Bosch Therm 330PN is the Direct Replacement for Bosch 1000P

The new Bosch Therm 330PN is the direct replacement for the retail model Bosch 1000P.  Bosch is no longer making the retail model heaters and is only selling wholesale versions.  The Bosch 330PN comes in either Natural Gas (NG) or Liquid Propane (LP).  The only difference between the 330PN and the retail model 1000P is the color of the front cover.  The 330PN has a silver cover as the older 1000P had a white cover.  All of the other specifications are the same.

Specifications for Bosch Therm 330PN:

• Piezo ignition system requires no electrical connection
• 78%+ thermal efficiency
• 75,000 BTU maximum input
• 3.3 gallons per minute capacity at 35F degree rise
• Endless hot water for 1 application at a time
• Minimum activation flow rate of 0.5 gallons per minute
• Minimum of 30 psi water pressure required
• High to low temperature control
• Vents with 4" galvanized B vent – natural draft
• Built for durability and serviceability with 15-year warranty and 20+ year life expectancy
• Available in NG and LP models

The Bosch 330PN is also a good replacement heater for the older Aquastar 38B as they both are similar in BTU size and both take a 4" vent pipe.

The Bosch 330 PN could also replace the older Paloma PH6.  The 330 PN is 75K BTU and the PH6 was 43,800 BTU but both heater are good for small applications for camps and cottages.  The 330PN takes a 4" vent pipe like the PH6 did.  Please be aware that the 330PN requires a minimum of 30 psi of water pressure.

Installing Bosch Gas Tankless Water Heaters in Bathrooms & Bedrooms

It is very dangerous to install a Bosch gas tankless water heater or any other gas appliance in a bathroom or bedroom that draws it's combustion air from that room.  Any Bosch gas tankless water heater or gas appliance that is naturally drafting and draws it's combustion air to burn from the room it is installed would deplete the oxygen in the room and cause asphyxiation.  The only Bosch gas tankless water heaters that are approved for installation in a bathroom or bedroom would be the direct vent ones.  The direct vent units are a twin pipe system and exhaust their gas to the outside and also take their combustion (intake) air from the outside.  Any direct vent unit installed in a bedroom or bathroom MUST take the combustion air from the outside.

It is against National Fuel Gas Code (NFGC) section 10.28.1 to install a gas fired appliance in a bathroom or bedroom where the door is normally kept closed.  This refers to all gas appliances that take their combustion air directly from the room they are in.  The only time a naturally drafting gas appliance shall be installed in a bathroom or bedroom is if they are installed within a closet with a self closing weather-stripped door with no openings.  All combustion air shal be obtained from the outdoors in accordance with section 9.3.3 of the NFGC.

Please also consult your local codes and local inspector for a safe installation.  Remember it is your life!

Replacing an Aquastar 125BL Low Pressure Unit with a Bosch 345ESR/450ESR

The older Bosch Aquastar model 125B LP L (Liquid Propane) or 125B NG L (Natural Gas) was 117,000 BTU and was a naturally drafting unit that was good for one major application at a time. The Aquastar 125BL unit was a low pressure unit design for non modulating applications for heating systems in conjunction with domestic hot water.  The Bosch 125BL had a standing pilot light and took it's combustion air from the room it was installed in.  The 125BL had to be vented with a 5" B-vent double wall venting going a minimum of 6' up through the roof vertical to a raincap.  The 125BL unit could have been vented out the sidewall also with the AQ1 powervent kit (now discontinued). The Bosch Aquastar 125BL unit is discontinued now and has not been made for over 8 years or so. The replacement model for the older Bosch Aquastar 125BL would be the Bosch 345ESR or 450ESR recirculating units.

Bosch 345ESR/450ESR

The gas tankless recirculating heaters, Bosch 345 ESR and the Bosch 450 ESR are temperature modulated and have electronic ignition. The ESR stands for Electronic ignition, Sealed combustion and Recirculating. These recirculating heaters are designed and approved for heating and recirculating potable water in conjunction with an indirect storage tank.  The Bosch 345ESR and the Bosch 450ESR would be able to replace the older Aquastar 125BL unit but there would have to be significant changes such as the venting is stainless steel, combustion air taken from outside using 3" PVC and that the gas line sizing would have to be appropriate.

The 345/450 ESR are not approved or designed for closed loop heating applications. The ESR units are not a tankless heater as they have no flow switch to respond to flow. Instead it’s a recirculating water heater designed for tank loading applications such as the older Aquastar 125BL units were designed for. When an AquaStat (not included) hooked up to a tank tells the ESR that water needs to be brought back up to temperature, the ESR will tell a circulator (not included) to turn on to create flow through the heater to reheat the water in the tank. Please refer to the installation and applications manual.  The basic setup for the indirect tank, aquastat, recirculation pump, check valves, etc. should be basically the same for the new ESR heaters.

The Bosch 345 ESR recirculating heater is a 95K BTU unit and can deliver 3.5 GPM at a 45 degree rise. Efficiency is 82%


The Bosch 450 ESR recirculating heater is a 120K BTU unit and can deliver 4.5 GPM at a 45 degree rise. Efficiency is 81%

The temperature control range for both heaters can be set anywhere from 115°F (45°C) - 190°F (90°C)

The 345/450 ESR comes with a standard ¾” pressure relief valve.

The 345/450 ESR has a special built-in freeze prevention cycle and is controlled by a sensor. Freeze protection is always assured by the operation of the appliance. If the primary NTC (temperature) sensor detects temperatures 9°F below the selected temperature, the appliance starts on minimum power until the sensor reads selected temperature. In the case of minimum set point temperature then it will start at 41°F. The use of non-potable additives like glycol is not approved.

The Bosch 345 ESR and the Bosch 450ESR must be installed indoors according to the provided installation manual. The 345/450 ESR is NOT approved for outdoor installations.

The Bosch 345/450 ESR recirculating heaters must be vented in accordance with the installation manual and require Category III 3” stainless steel sealed venting for the exhaust. These heaters are direct vent units and must be vented directly to the outside in accordance with the installation manual. These heaters cannot be combination vented with any other appliance. The intake should be taken from the outside and 3”PVC or other material can be used only for the intake air.

The Bosch 345/450 ESR recirculating heaters are gas specific so they cannot be converted from one gas type to another.

Replacing an older 125FX LP with a Bosch 660EF LP

The older Bosch Aquastar model 125FX LP (Liquid Propane) was 117,000 BTU and was a direct vent unit that was good for one major application at a time.  The 125FX LP had electronic ignition and was fan assisted and took it's combustion air from the room it was installed in.  The heater had a built in fan so the heater could be vented right out the sidewall of the building.  The 125FX LP had to be vented with a 4" sealed stainless steel venting going a maximum of 15' out the sidewall of the building into the FXHood.  The FX Hood was a termination hood specifically designed for the 125FX LP and had a built in flapper to keep cold air from penetrating the vent pipe and freezing the heater.  The Bosch Aquastar 125FX LP is discontinued now and has not been made for over 8 years or so.  The replacement model for the older 125FX LP would be the Bosch 660EF LP.

Bosch 660EF LP



The Bosch 660EF LP can be used for a direct replacement for the older Bosch Aquastar 125FX LP.  The 660EF Lp is also a direct vent unit, it is 140,000 BTU and has electronic ignition and is fan assisted to vent right out the sidewall of the building.  The 660EF LP has 3/4" water and gas connections on the bottom of the heater.  The 660EF LP also takes it's combustion air from the area where it is installed.  The 660EF LP is designed for 3" stainless steel venting and has a special 660EF adapter required for the top of the unit to attach the venting to.  You would then need to use a 3" to 4" increaser so you could go to 4" stainless steel venting and can then be adapted to hook up right to the existing FXHood.

If the older Bosch Aquastar 125FX LP was originally installed with 4" galvanized venting and there was no FX hood in place then the installer could use the AQ5EF sidewall vent for the new Bosch 660EF LP.  The AQ5EF sidewall vent kit comes with the 660EF adapter, 3"x90 degree elbow, 3oz tube of high temp sealant, wall thimble, termination box, a 3"x12" piece of stainless pipe and a 3"x18" piece of stainless pipe.



Z-Flex 3" & 4" Silicon Seals for Stainless Steel Venting

Z-Flex Inc. is a major manufacturer of category 3 stainless steel venting material (AL29-4C).  All of the stainless steel venting is a sealed vent pipe.  The stainless steel vent pipe has a seal on one end inside the female end of the pipe.  The vent pipe has a built in clamp on the female end also. 

The seal on the inside of the 3" & 4" stainless venting keeps the vent pieces sealed when connecting them together.  If there is ever a need to take the venting pieces apart then the gaskets would have to be replaced as they would be damaged by the prior heat and condensation.

Globaltowne has extra 3" & 4" replacement silicon seals in stock in case the venting has to be taken apart.  These seals are required for all the stainless venting and prevent any gasses from getting out into the home.

New Ariston GL6+S Electric Mini-Tank Water Heaters

The new Ariston GL6+S electric mini-tank water heaters have just arrived. This water heater is the direct replacement for the recently obsoleted Ariston GL6+ (GL6PLUS).

The main difference between the older GL6+ and the new GL6+S is that the GL6+ came with a power cord that plugged directly into a 120V wall socket while the new GL6+S does not come with a power cord. The GL6+S must be hardwired at the time of installation.

Globaltowne does carry a 6' cord for the Ariston GL6+S

Here are the features of the new GL6+S:

• 6-year warranty on tank
• Glass-lined tank for longer life
• Mounts on wall or floor
• Temperature/pressure relief valve included
• Must be hard-wired to 120V
• Dimensions: 17.5" x 17.5" x 14 1/2"
• Recovery at 90 Deg F Rise: 7 GPH
• 12.5 AMPS and 1500W Heating Capacity
• Temperature Range: 65 Deg F to 145 Deg F
• Meets ASHRAE 90.1 Standard
• Relief Valve = Installed
• Power cord not included

The new Ariston GL6+S model has many new improvements since it has been upgraded. The mini tank has a new temperature adjustment knob on the front of the unit to raise and lower the temperature from 65 Deg F to 145 Deg F. On the older model you would have to remove the blue oval cover to access the temperature knob.

The Ariston GL6+S model has a new improved thermostat that features a new sensing probe that is attached to the thermostat and inserts into the cavity of the new element so the heater can adjust temperatures quicker and maintain a more consistent heat.

Venting requirement for Bosch AQ4 Powervent Kit

The Bosch AQ4 Powervent Kit with built-in freeze protection is designed for the Bosch 1600H (Hydro Ignition) and 1600P (Pilot) tankless water heaters. This accessory allows the Bosch 1600H and 1600P tankless heaters to vent horizontally out the sidewall of the home. The AQ4 does require power to operate and operates on 120V and comes with a 3' cord to plug into the outlet.

The AQ4 is a power vent kit and will allow a horizontal vent run of up to 25 feet with one elbow (subtract 5 feet for every elbow). This kit includes the power vent motor. There is also a vent hood with damper that gets mounted on the outside of the home and this built in flapper prevents the cold air from coming in when the heater is not in use. Please make sure to refer to the installation manual and that the hood is properly installed so that the flapper stays closed all the way when not in use.

The AQ4 powervent kit comes with a 5" to 4" reducer. This reducer fits right on top of the heater and then you would use 4" type B, C or stainless steel AL29-4C venting (not included) to go to the powervent motor. There is a minimum of 2 feet of straight pipe required between the reducer and the blower motor. Any venting (if needed) "after" the powervent motor must be 4" sealed stainless steel AL29-4C. The Blower motor should be placed right at the opening where the termination hood with damper is to be installed on the sidewall of the home.

The AQ4 powervent kit is activated by a flow switch and gets attached to the cold water pipe on the right side of the unit just before it goes into the heat exchanger.

The blower motor for the AQ4 has a new design and includes a delay setting that goes from #1 - #5 and this lets the installer set the blower motor so that when it senses flow it can be delayed for 1 - 5 seconds before the blower comes on. This will help to ensure the pilot and burners light without getting sucked out by the blower motor.

There is also a built in safety spill switch that gets attached to the tankless water heater and this will detect high temperatures from any flue gases in the case the blower motor does not activate and will shut the unit completely down.

Timers for Ariston Mini-Tank Water Heaters

Globaltowne now has timers for the Ariston Mini-Tank water heaters.  Call to order - 888-726-9752

By using a 24 hour or 7 day timer you can save money by turning off the water heater during times when you are sleeping or not at home.  The Ariston's take from 15 to 30 minutes to heat up.  Set the timer to turn off the heater at a time when no one will require hot water, then set the timer to turn the heater back on 15 to 30 minutes before hot water is needed.  The 24 hour or 7 day timer can handle up to 15 amps and has a three prong 120 volt plug.  The 24 hour timer can be set for up to 24 on or off times per day.  The 7 day timer can be set for up to 6 on or off times per day.

To Install, plug the timer into a standard outlet or GFCI protected outlet and then plug the heater into the socket on the timer.  Use the tabs to set the times on the timer for the on and off cycles.  Now your heater will not be using power when it is not necessary.

Please note that some of our competitors are advertising the AQ3ES Horizontal Vent Kit as a side-wall kit option for the Bosch 660EF. Be warned that the AQ3ES Vent Kit does not fit the bill! The AQ3ES Vent Kit is missing the correct Bosch 660EF Adaptor and the high temperature silicone sealant. And it has an air intake piece and gear clamps that are not needed with the Bosch 660EF heaters.

Lastly, our company is the only company selling the correct Bosch 660EF Adaptor. For several years the wrong adaptor was sold and we have worked directly with Z-Flex to develop a proper adaptor.

Auto Reset Ground Fault Circuit Interrupters (GFCIs)

As Hurricane Sandy rolled across the US East Coast I lost power twice. I have a 199,000 BTU Bosch Tankless Water Heater in my house that has an electronic ignition. I have my tankless water heater plugged into an Auto Reset GFCI with an 18" cord.

I didn't even think about it until this morning, but both times I lost power my tankless water heater was protected -- and I didn't even have to go down to my basement to reset my GFCI when the power was restored!

Most wall mounted Ground Fault Circuit Interrupters have the Auto Reset feature. But most GFCI extension cords do not have the Auto Reset feature. The GFCIs from GlobalTowne have this Auto Reset feature and this weekend it was appreciated.

Bosch Heaters are LOW NOx

Bosch Therm Units meet low NOx - Gas Tankless Water Heaters

Bosch Thermotechnology North America, a leading provider of energy efficient water heaters, heating and air conditioning comfort systems as well as high quality solar thermal systems for commercial and residential use, announced today the following Therm tankless products from Bosch meet recently enacted Low emission (NOx) requirements passed by utility regulatory agencies in California and Vermont: Therm C 1210 ES/ESC; C 1050 ESC; 950 ES; 940 ES/ESO and 830 ES. All models offer NOx emissions of 14 ng/J or 20 ppm or less. California and Vermont are currently the first two states to enact the 14 ng/J or 20-ppm NOx level.

In accordance with the new guidelines as published in new Air Quality Management District (AQMD) ordinances, the following Bosch models will no longer be sold nor allowed for installation in areas that are subject to these AQMD ordinances: Therm 520 PN/HN; 330 PN, and 660 EF/EFO. AQMD’s are regulatory agencies supported by state government to help control and preserve air quality standards for a given area.

Therm units from Bosch include a unique design using a wide flame pattern and secondary dilution air that results in a lower flame temperature during the heating process. Combined with condensing technology, which utilizes a secondary heat exchanger to capture more heat from the exhaust for preheating incoming cold water, these models offer an attractive tankless water heating option that meets future code requirements today while offering optimal efficiency.

The complete Therm line from Bosch features models with updated software that delivers performance-enhancing characteristics including a minimum activation flow rate of 0.5 gallons per minute (GPM) and the ability on many models to cascade up-to-24 units for larger commercial applications. The Therm line includes ENERGY STAR® rated models, powered by natural gas or propane, which have an industry best 15-year warranty.

HVAC & plumbing professionals and affected homeowners in California and Vermont are encouraged to check with local regulatory agencies to ensure compliance of all tankless units with the new low NOx requirements.

Bosch Wireless Remote Control TSTAT2

The Bosch Wireless Remote Control TSTAT2 for the Bosch AquaStar 2700ES / 2400ES / 2400E / 2400EO / 250SX / 250SXO allows you to program your Bosch tankless gas water heater to a comfortable and safe temperature from around your home from a distance of up to 98 ft.

The TSTAT2 remote is particularly useful if you own a jacuzzi or hot tub that requires a hotter water temperature than you normally desire for regular shower use.

Please note that the electrical control of the Bosch AquaStar 2700ES / 2400ES / 2400E / 2400EO / 250SX / 250SXO must be removed and opened in order to install the wireless receiver circuit board to enable the use of the TSTAT2 Wireless Remote Control.

The Newer Bosch models, 2700ES and Bosch 2400ES tankless water heaters have been redesigned to make the installation of the wireless receiver circuit board much easier. The circuit board is basically a plug and play unit.

The TSTAT2 controls the temperature of your water heater and does not have a reset button.   If the heater has an error then a code will be on the display of the heater and the user has to go to the heater to reset it from there and should document the error and then see if it returns after resetting.

The TSTAT2 Wireless Remote Control for Bosch 2700ES / 2400ES /2400E / 2400EO / 250SX / 250SXO features the following:

• LCD displays temperature, error codes and functions
• Temperature measured in °C or °F
• Low battery level indicator
• 98 feet user range
• Alkaline AA LR6 2x1.5V battery power 915 MHz
• Security lock function
• IP X6 Protection
• Priority function - temperature cannot be modified by other user interface when water is running

Don't forget to periodically change the two AA batteries in your Bosch wireless TSTAT2 thermostat as they will certainly corrode over time. The batteries in TSTAT2 thermostats that are kept in bathrooms will corrode faster than in other less humid environments, such as kitchens. Your batteries should be checked yearly for any signs of corrosion and replaced every five years in any case.

Freeze Protection for Bosch Gas Tankless Water Heaters

Most all of the Bosch gas tankless water heaters come with built in freeze protection.  The heaters listed below have built in freeze protection and are approved to be installed in some outside installations.

Our Bosch Outdoor Tankless Water Heaters (Bosch 2700ES with AQOK Outdoor Cap / Bosch 2400ES with AQOK Outdoor Cap/ 125BO / 425HNO / 2400EO / 250SXO) have built in freeze protection and are designed to handle an occasional overnight freeze. They plug directly into the wall and provide freeze protection down to 5 deg F above zero. In order for the freeze prevention kit to provide adequate protection,120V AC must always be supplied to the water heater.They are approved for use in the following areas:


Florida, Georgia, North Carolina, South Carolina, Alabama, Mississippi, Arkansas, Texas, Virginia (only in zip codes beginning with the first three digits 233-237), Arizona (in zip codes beginning with the first three digits 850-857 and 864), Oregon (in zip codes beginning with the first three digits 970-975), Washington (in zip codes beginning with the first three digits 980-986), California (except in zip codes beginning with the first three digits 935 or 961).

Installation instructions state that the water heaters must not be installed in a location where it may be exposed to prolonged freezing temperatures. If the heater must be left in a space which is likely to experience prolonged freezing temperatures, all water must be drained from the heater.  If precautions are not taken, resulting damage will not be covered under the warranty. NOTE: Use of agents such as anti-freeze is not permitted as they may cause damage to the water heater's internal components.  The freeze prevention will not protect plumbing outside the appliance from freezing. Precautions should be taken.

The Bosch 250SX/2400E/2400ES and 2700ES come with built in freeze protection and these units are for inside installation only.  The freeze protection helps the unit if it is installed on the inside of an outside wall where it may be cooler than normal.

Bosch AquaStar 2700ES vs. Bosch Evolution 500 Tankless Water Heaters

The Bosch AquaStar 2700ES is Bosch's top-of-the-line 199,000 BTU retail tankless water heater. As a retail tankless water heater the Bosch 2700 ES can be sold directly to home owners and is the perfect water heater for Do-it-yourselfers (DIY).

The Bosch 2700ES is available in both natural gas (Bosch 2700ES-NG) and liquid propane (Bosch 2700ES-LP). The 2700 ES direct vent tankless water heater requires special 3" or 4" stainless steel vent pipe and can be vented either through the roof or out the side wall. In approved areas the 2700ES can also be mounted outdoors as it comes with freeze protection that is good down to 5 degrees F above zero and provides protection against occasional overnight freezes.

In addition to coming with built-in freeze protection, the AquaStar 2700ES also comes with a pressure relief valve (PRV) and an external water filter.

The Bosch Evolution 500 is identical to the Bosch AquaStar 2700ES. It also comes in natural gas (Bosch Evolution 500 NG) and liquified petroleum (Bosch Evolution 500 LP) models. As a heater in Bosch's professional line of tankless water heaters, however, the Bosch Evolution 500 can only be sold to licensed installers or builders. As a Bosch Professional heater the Evolution 500 comes with a 15 year warranty on the heat exchanger and 5 years on all other parts.

Like the 2700ES, the Evolution 500 direct vent tankless water heater also comes with built-in freeze protection, a PRV and an external water filter. It requires the same Z-Flex Z-Vent 3" or 4" special stainless steel vent pipe.

So, if you intend to have your tankless water heater installed professionally, have your installer visit www.prowaterheatersupply.com and check out the Evolution 500. These heaters are specially priced while supplies last.

Gas Conversion for Bosch Retail Gas Tankless Water Heaters

Some of the Bosch Retail gas tankless water heaters can be converted from one gas type to the next, i.e. from Natural Gas (NG) - Liquid Propane (LPG) and also from LPG - NG. The Gas Conversion Kit, part #8719002176 includes a jumper for placement on the control board, a set of instructions for calibrating the gas and air mix and also some stickers to be placed on the heater stating it has been converted.

The tools required for the gas conversion are: 

• Flat and Phillips Screwdrivers
• #40 torx driver
• Digital CO2 Gas Combustion Analyzer
• This procedure must be performed by a licensed gas technician

The Bosch Retail Gas tankless water heaters that CAN be converted using the gas conversion kit are the 2700ES/2400ES/2400E/2400EO/250SX/250SXO.

The Bosch Retail Gas tankless water heaters that CANNOT be converted are the 1600H/1600P/1000P and all of the 125 series heaters as they are not designed or approved at all for gas conversion.

NEW Ariston GL2.5S & GL4S Mini Tank Heaters

Designed by the world's leading point-of-use water heater manufacturer, the New Ariston GLS series combines Italian design and state of the art features including glass-lined tanks, a 6-year warranty and highest recovery time.

Installing an Ariston electric mini-tank water heater under the sink puts hot water right where you need it - at the point of use. Lightweight and compact and also the Ariston mini tank heaters are great for those long hot water runs from your tank heater or tankless heater and will shorten the wait time for hot water.

The New Ariston GL2.5S mini-tank electric water heater stores 2.5 gallons of hot water.

The New Ariston GL4S mini-tank electric water heater stores 4 gallons of hot water.


Please note: The New Ariston GL2.5S is not the direct replacement for the Ariston GL2.5 as the Ariston Gl2.5S is 10 3/4" in depth and the older Ariston GL2.5 was 10 1/4" deep.  The new Ariston GL4S is not the direct replacement for the Ariston GL4 as the GL4S is 13 1/2" in depth and the older Gl4 was 12 1/4" deep.  The replacement parts for the new Ariston GL2.5S and the GL4S will not work for the older GL2.5 and GL4 mini tank heaters.


 

• 6-year warranty on tank 
• Glass-lined tank for longer life  
• Mounts on wall or floor 
• Temperature/pressure relief valve included  
• Plugs into standard 120 volt outlet

The Ariston GL2.5S & GL4S models have a new improved thermostat that features a new sensing probe that is attached to the thermostat and inserts into the cavity of the new element so the heater can adjust temperatures quicker and maintain a more consistent heat.

The new Ariston GL6+S can either be hard wired to an independent breaker or wired to a power cord with 3 pronged plug.  Globaltowne has a 6' power cord in stock for the GL6+S.
