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.

Come home to hot water or a lighted house by using a timer to turn on and off heaters, lights, seasonal displays or electric candles so you can enjoy your decorations without having to turn them on and off.

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.

We worked directly with Z-Flex to develop a custom adaptor that properly fits the 660EF heaters.

We also carry the AQ5EFPLUS 660EF Horizontal Vent Kit which contains all parts from the AQ5EF kit PLUS a GFCI with an 18" extension cord and a Webstone 44443PR Isolation Valve Kit.

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 and check out the Evolution 500. These heaters are specially priced while supplies last.

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.

  • Glass-lined tank for longer life  
  • Mounts on wall or floor 
  • Temperature/pressure relief valve included

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.

Bosch Retail Water Heater Program Changes

Bosch Thermotechnology has stopped manufacturing and distributing its retail line of Gas and Propane Bosch tankless water heaters. It appears that Bosch has decided to step back from the do-it-yourself (DIY) model of selling this wonderful brand of gas and liquid propane tankless water heaters directly to homeowners.

As a Bosch Authorized Distributor, GlobalTowne still has a supply of these heaters. So, if you are a homeowner looking for a gas or propane Bosch Tankless Water Heater that you can purchase and install on your own, act quickly as these retail tankless water heaters are going fast!

Just to be clear, the Bosch retail line of PowerStar electric whole-house and point-of-use tankless water heaters and Ariston mini-tank electric water heaters are still being manufactured and distributed. In fact, Bosch is in the process of rolling out newly-improved electric water heaters!

Now for the really good news: Bosch's commitment to their wholesale line of Gas and Propane Bosch Therm tankless water heaters has never been stronger!

The entire retail lineup of Gas and Propane Bosch tankless water heaters are available on the wholesale side of the business. But, even more importantly, the Bosch Pro gas and propane wholesale lineup includes super high efficiency Condensing Tankless Water Heaters that were never available through the retail channel.
