Selkirk 5 Inch Type B Venting Double-Walled Galvanized

GlobalTowne stocks 5" Selkirk Metalbest Type B Double-walled Galvanized vent pipe for the Bosch AquaStar 1600H and 1600P tankless water heaters.

The Selkirk Metalbestos 5" Type B vent pipe will connect up directly with the 1600H and 1600P tankless hot water heaters and will also connect up directly with the Bosch H/P VVT vertical vent kit.

The Bosch H/P VVT vertical vent kit contains all of the venting parts needed to vent the Bosch 1600H and 1600P heaters through the roof except for the straight pipe.

Our customers have found that ONLY the Selkirk Metalbest vent pipe will mate up with the H/P VVT vent kit piping, so this is the 5" Type B venting that we stock.

Z-Vent Installation Tips and Hints

GlobalTowne is one of Z-Flex's largest distributors in the US. We carry all of the Z-Flex Z-Vent stainless steel vent pipe that is needed to exhaust tankless water heaters and boilers.

Here are some generic Z-Vent Installation Tips and Hints directly from the vendor:

1. A venting system that exits the structure through a sidewall or the like, shall terminate not less than 12 inches (254 mm) above the ground.
2. The termination of a system shall be located above the snow line in geographical areas where snow accumulates. The termination area should be kept clear of snow and ice at all times.
3. The vent shall not terminate less than 7 ft. (2.13 m) above a paved sidewalk or driveway.
4. The termination shall be 6 ft. (1.8m) or more from the combustion air intake of any appliance.
5. The system shall terminate more than 3 ft. (.91 m) from any other building opening, gas utility meter, service regulator or the like.
6. Exterior mounted venting systems should be enclosed below the roof line with a chase to limit condensation and protect against mechanical failure.

Always refer to your tankless water heater or boiler's Installation Manual as their requirement may differ from these Z-Vent Tips.

AE 115 and AE 125 Heaters and control

Many times we have been asked if the Bosch AE115 and Bosch AE125 can accept pre heated water. The answer is no.

The reason lies in how the unit controls the temperature. These large KW whole house tankless water heaters are designed to take cool water and heat the water to shower temperature as the water passes through the heater. The heater turns on as flow is detected and turns off when the water flow ceases.

There is a temperature sensor on the inlet water pipe (cold) and a sensor on the outlet pipe (hot). The switch that turns the heater on is a solid state style switch or SCR switch. This type of switch has no moving parts and is very reliable. However, SCR or solid state switches generate heat as they switch electrical current. To cool these switches, they have been located on the inlet (cold) water inlet. So the copper pipes act as a heat sink for the SCR switches. If hot water is passed through the pipes and the heater turns on the SCR switches could over heat and FAIL.

Call us for any applications involving the need to have pre-heated water through a tankless heater. We can provided gas and electric heaters for floor heating or other applications needing to circulate warm or hot water.

Bosch 2700ES Vs. Bosch Pro 715ES - A Comparison

The Bosch AquaStar 2700ES tankless hot water heater is similar in many respects to the Bosch Pro 715ES tankless hot water heater.

They are both 199,000 BTU tankless water heaters and they both sit in the same chassis or case - the new "World 2" case.

Both have modulating gas valves and have the same .65 GPM minimum activation rate.

There are a few key differences between the two heaters, though.

One key difference is that the Bosch 2700ES comes with built-in freeze protection. This freeze protection is meant to keep the heater from freezing in locatons that experience occasional overnight freezes. The Bosch Pro 715ES does not come with this freeze protection -- but it is an optional accessory that you can pay extra for.

Another difference between these two heaters is the water filter.

In the Bosch 2700ES tankless hot water heater the water filter comes with the heater and is very easily accessible without having to even remove the cover. As you can see from this image, (1) is the water filter.

Bosch recommends that you inspect and clean the water filter once per year as part of your annual maintenance of the heater.

With the Bosch Pro 715ES, the water filter is an optional accessory - albeit a highly recommended accessory!

The Bosch Pro 715ES is a wholesale product that is meant to be sold directly to an installer. It is designed to be professionally installed. As such, it comes with a 15 year warranty. The Bosch 2700ES is a retail product that is meant to be sold directly to home owners and it comes with a 12 year warranty.

Z-Flex 3" Termination Options for Bosch 2700ES/2400ES Tankless Water Heaters

We stock the full line of Z-Flex Z-Vent 3" and 4" stainless steel vent pipe. There are a variety of termination options for both the 3" and 4" venting.

All of our termination pieces come with a built-in bird screen to ensure that birds and other critters cannot get into your venting system.

The AQ3ES Side Wall Vent Kit for the Bosch 2700ES and 2400ES tankless water heaters comes with the 3" Termination Box with a 10" sleeve (2SVSTB03). This special OEM part is exactly the same as the Z-Flex part 2SVSRTF03. The 2SVSTB03 and the 2SVSRTF03 can both also be used for intake air.

If you have vinyl siding then you do not want to use the 2SVSTB03 or 2SVSRTF03 Termination Box as the hot exhaust gases may melt your vinyl siding. The recommended part for vinyl siding is the 3" Termination Hood (2SVSHTX03). This part can also be used for intake air.

We also sell the 3" Termination Hood with Damper (2SVSHTD03), but this part is not approved for either the Bosch 2700ES or Bosch 2400ES tankless heaters. The concern is that if the damper gets frozen shut then the exhaust gases cannot escape. The 3" Termination Hood with Damper cannot ever be used for intake air!

We carry the 3" Termination Coupling (2SVSTPF03). This will exhaust the gases straight out from your house, so safety is a concern when using this part for exhaust. This part can be used for either exhaust or intake.

The 3" Termination Tee (2SVSTTF03) exhausts the gases out in two directions. This part can also be used for intake air.

The 3" Termination Elbow (2SVSTEX0390) will shoot the exhaust gases out in a single direction. This part can also be used for intake air.

The Z-Flex Z-Vent 4" stainless steel vent pipe part numbers are as follows:

• 4" Termination Box 2SVSRTF04
• 4" Termination Hood 2SVSHTX04
• 4" Termination Hood with Damper 2SVSHTD04
• 4" Termination Coupling 2SVSTPF04
• 4" Termination Tee 2SVSTTF04
• 4" Termination Elbow 2SVSTEX0490

Noritz 0751 Series Residential Tankless Water Heater

Today we received a call from a customer who was looking for 4" stainless steel vent pipe for his Noritz 0751 Series Residential Tankless Water Heater.

He wanted to purchase Z-Flex vent pipe and wanted to know the correct venting adaptor for this heater. He also wanted to know how to connect the Z-Flex exhaust to his Noritz VT4-TL Sealed Combustion Long Vent Termination.

The correct Z-Flex adaptor for the Noritz 751M-DV tankless water heater is the 4" Noritz Adaptor (2SVWA04). This adaptor connects directly to the heater and allows you to exhaust with Z-Flex 4" stainless steel vent pipe.

The Z-Flex Stainless Steel Vent Pipe connects directly to the Noritz VT4-TL Sealed Combustion Long Vent Termination.

ESHCK Concentric Vent Kit for Bosch 2700ES / 2400ES

Bosch has recently approved the ESHCK Concentric Vent Kit for the Bosch AquaStar 2700ES, 2400ES and 715ES tankless water heaters.

The ESHCK side wall concentric vent kit is actually a shell piece of stainless steel venting that will work with vent pipe manufactured by Z-Flex, ProTech Industries or Heat-Fab. (Of course, we always recommend using Z-Flex stainless steel AL29-4C vent pipe.)

Part number ESHCK is a 5" diameter shell through which you can stick a 3" x 3' piece of stainless steel vent pipe. This piece of straight pipe is terminated by either a Termination Tee or a Termination Elbow. The ESHCK shell that fits around this straight pipe creates the air intake vent pipe.

The air intake from the Bosch 2700ES, 2400ES or 715ES tankless water heater can be run using PVC and connects directly to the ESHCK. The air intake port on the ESHCK can be rotated 360 degrees around the ESHCK to bring the combustion air in from any angle. Bosch recommends that you bring the air in from the top, particularly in areas that are prone to freezing.

The ESHCK is actually 20" long, but when you stick the 3" x 3' pipe and the termination piece through the ESHCK then the total length of the ESHCK Vent Kit is about 41" long. When you add the required 3" x 90 degree elbow the total length is about 47" long. The square flashing that rests against the outside wall is 8" square.

Bosch requires that the termination tee or termination elbow be a full 12" away from your exterior wall. This is meant to ensure that the exhaust air does not get recylcled back through the air intake. Don't go beyone the 12" either as this may increase your potential for condensation in the exposed pipe section.

We sell a complete kit called the ESHCK-FULL-KIT Concentric Vent Kit that includes the ESHCK shell, a 3" x 90 degree elbow, a 3" x 3' stick of pipe and a termination tee.

Please note that this concentric vent kit will protrude quite a bit through the inside wall making it very difficult for you to mount the tankless water heater on the same wall that you are venting out of. The easiest way to use this ESHCK concentric vent kit is to mount your tankless water heater on a wall that is perpendicular from the wall that you are venting out of.

With this configuration, you will need a 90 degree elbow coming off of your water heater. Then we recommend using a horizontal drain pipe to catch any condensate that gets generated. Then you may need additoinal straight pipe to connect up to the ESHCK concentric vent kit which protrudes from the wall.

If you do want to do and "up and out" venting through the same wall you mount the heater on with the ESHCK then you will need to install your 2700ES or 2400ES tankless water heater out away from the wall. This will help you avoid using an excessive number of 90 degree elbows.

One of the big advantages of using the ESHCK concentric vent kit is that you only have to have a single hole through your exterior wall. This may greatly reduce your installation costs if you have a difficult wall to drill through, such as a thick stone wall.

Another advantage of using the concentric vent kit is that for some installations it is impossible to meet the 3' distance requirement between the exhaust and the air intake.

Aesthetically it may also be more desireable to have a single vent through your outside wall.

Please see the Bosch 2700ES Installation Manual or the 2400ES Installation Manual for the full details of installing the ESHCK Concentric Vent Kit.

Propane and Propane Tankless Water Heaters

There has never been a better time for propane to fuel American homes. Homeowners are looking for smart approaches to enhancing home enjoyment and value while minimizing environmental impact. Whether providing an instant flame for gourmet cooking or offering an endless supply of hot water in the shower or backyard pool, propane is helping millions of American families enjoy richer, more comfortable lives with less impact on the planet. And the lower cost of operation means homeowners will be rewarded for a smart choice each month with lower energy bills. Getting more for less while helping the environment - that’s a message worth sharing.

Fact: Propane delivers instant hot water with a lighter impact on the environment.

• Propane tankless water heaters produce 61 percent fewer greenhouse gas emissions than electric tankless models.¹
• Propane tankless water heaters save families an average of 10 to 20 percent of their daily water use.²
• Propane tankless water heaters reduce standby energy loss by up to 20 percent compared with tank water heaters.²
• Propane tankless water heaters cost approximately 60 percent less to operate than tank water heaters.²
• Propane tankless water heaters are Energy Star qualified for efficiency; electric tankless water heaters are not.

Note: Using any kind of Tankless Water Heater is better for the environment than using a tank water heater. And even though electric tank water heaters are not energy star rated, that are significantly more environmentally friendly and less costly to operate than even Energy Star rated electric TANK water heaters.

Determining Your Water Flow Rate for Tankless Water Heaters

Selecting tankless hot water heaters isn't very difficult. Select one based on the maximum amount of hot water to meet your peak demand.

Selecting Tankless Water Heaters

Selecting tankless hot water heaters isn't very difficult. Select one based on the maximum amount of hot water to meet your peak demand. Use the following assumptions on flow for various appliances to find the size of unit that is right for your purposes: Faucets: 1.0 gallons (3.78 liters) to 2.5 gallons (9.46 liters) per minute.

Low-flow showerheads: 1.0 gallons (3.78 liters) to 2 gallons (7.57 liters) per minute. Older standard shower heads: 2.5 gallons (9.46 liters) to 3.0 gallons (11.36 liters) per minute.

Clothes washers and dishwashers: 1 gallon (3.79 liters) to 2 gallons (7.57 liters) per minute.

Unless you know otherwise, assume that the incoming temperature is 55° F (12.78° C). You will want your water heated to 110° F (43.33° C) for most uses. To determine how much of a temperature rise you need, subtract the incoming temperature from the desired output temperature. In this example, the needed rise is 55° F (12.78° C).

List the number of hot water devices you expect to have open at any one time, and add up their flow rates. This is the desired flow rate for the heater. Selecting a tankless water heater is nearly impossible without knowing the flow rate you need.

As an example, assume the following conditions: One hot faucet open with a flow rate of 1.0 gallons (3.79 liters) per minute. One person bathing using a shower head with a flow rate of 2.5 gallons (9.46 liters) per minute. Add the two flow rates together. If the inlet water temperature is 55° F (12.78° C), the needed flow rate through the heater would need to be no greater than 3.5 gallons (13.25 liters) per minute. Faster flow rates or cooler inlet temperatures will reduce the temperature at the most distant faucet.

Installing Un-Sealed Bosch Tankless Water Heaters in Enclosed Occupied Spaces

Installation of un-sealed gas utilization equipment in bedrooms, bathrooms or any occupied rooms with doors normally kept closed is prohibited by standards set forth in the National Fuel Gas Code. These standards conform to all known building codes throughout North America and are included in your product installation manual.

Oxygen deprivation and carbon monoxide poisoning are serious health risks that can result from such installations, due largely to the lack of combustion and ventilation air present in enclosed spaces. Premature appliance failure is also a consequence of lack of combustion and ventilation air. For details pertaining to combustion and ventilation air requirements for your Bosch water heater, please refer to the product installation manual or contact a qualified service agency. Failure to properly install Bosch water heaters voids all warranties, written or implied.

If your un-sealed Bosch tankless water heater is installed in a bathroom, bedroom or enclosed occupied space, you are strongly urged you to have the unit relocated and its installation inspected by a qualified gas service agency.
