New Bosch Hydronic Air Handler

Global ProTankless Supply is pleased to announce that we are now selling the new Bosch Hydronic Air Handler Systems: AHU70 and AHU50. These systems are designed to be used in conjunction with the Bosch Greentherm C1050ES & C950ES units.  The new Bosch Hydronic Air Handler can replace furnaces with a ducted system, eliminating the need for a gas pipe, venting, and fresh air in-take required for furnaces.

The new Bosch air handler has an integrated control board that connects to the home’s thermostat. When the thermostat calls for heat, the air handler will turn on the integrated pump immediately and turn on the fan 30 seconds later to allow the heat exchanger to preheat. When the thermostat calls for cooling, the control board will only activate the blower.

The air handler connects seamlessly with tankless water heaters, transferring the highly efficient water heater’s hot water through a hydronic heating coil within the air handler. As the hot water circulates through the coil, warm air is sent through the residential duct system as the cool water by-product recirculates to the tankless unit to be reheated and reused.

Bosch Hydronic Air Handling Units AHU70 & AHU50

The Bosch hydronic air handler is available in two models, AHU 50 and AHU 70, which can be sized with most CFM and BTU output ratings to suit a range of home sizes.

The Bosch Hydronic Air Handler is designed to work efficiently with the ENERGY STAR rated Bosch Greentherm tankless water heater to provide a complete solution for home heat and domestic hot water.

The hydronic air handler can also be used with A/C systems - a compatible A/C coil can be placed on top of the hydronic air handler and the blower inside of the hydronic air handler turns ON when the thermostat calls for cooling.

For further information and to purchase a Bosch Air Handler please call Global ProTankless Supply at 866-289-4652.

Using Bosch Gas Tankless Water Heaters For Breweries & Distilleries

Did you know that it takes many gallons of hot water to make nice cold beer and this is why many breweries around the United States are starting to integrate gas tankless water heaters into their system. The Bosch gas tankless water heater keeps a more stable temperature and delivers endless gallons of hot water.

There are many different Bosch Gas tankless water heaters to choose from but the largest is the Bosch Therm C1210ESC commercial unit and comes in either Natural Gas (NG) or Liquid Propane Gas (LP).  The Bosch C1210ESC has a max temperature of 180 degrees and is great for brewing or cleaning the storage tanks.  The Bosch Greentherm C1050ES is also another great unit for a Brewery. The Bosch Greentherm C1050ES can reach temperatures up to 140 degrees F but after adding the high temperature kit the unit can also go up to 180 degrees F.  Depending on the size of the Brewery and the amount of hot water needed at one given time the Bosch gas tankless water heaters can be cascaded together to deliver more gallons per minute (gpm).  The Bosch Greentherm C1050ES can be cascaded with up to 24 units and deliver up to 290 GPM of hot water.

Depending on your needs for hot water and the amount used at one given time there are different applications such as tank loading as this may be more easy to use and store the hot water.

For your hot water brewing needs please call Global Pro Tankless Supply at 866-289-4652 to go over the many different Bosch gas tankless water heaters and the applications they can cover.

Bosch Gas Tankless Water Heaters and Tank Loading Applications

Global Pro Tankless Supply is always trying to make it easier to figure out the right Bosch tankless water heater that is designed for the right application.  A tank load system, because of the added storage, can provide a high peak flow with fewer tankless units and lower installed cost. This will cover the basics for a tank loading application that will enable the user to have more domestic hot water and can also be set up for heating applications.  The Bosch gas tankless models such as the C1210ESC/C1210ES/C1050ES/C950ES/940ES and 830ES are all capable and designed to work with a tank loading applications.  Tank loading can be done using a standard tank heater as a storage tank or an indirect tank such as the Bosch SST Indirect Storage Tanks.

Many of the tank loading applications range from small singular tank loading to commercial tank loading such as for hotels and Inns.  Please see the diagram below for a basic design of a tank loading application.

For all the different tank loading applications please review the Bosch Applications Manual or call Global Pro Tankless Supply at 866-289-4652.

Please refer to the installation manual for proper installation of the Bosch Therm Intelligent Cascading Kit.

Installing the Bosch Therm High Temperature Kit #7736500074

The Bosch Therm High Temperature Kit (7736500074) allows the maximum temperature of the Bosch tankless water heater to be raised from its normal maximum of 140 degrees F up to 180 degrees F.

The Bosch Therm High Temperature Kit is designed to work with the following Bosch tankless water heaters:  Greentherm C1050ES, Therm C10505ES, Greentherm C950ES, Therm C950ES, C800ES, Integra 500, 940ES, 940ESO, Evolution 500 and 830ES.

The Bosch Therm High Temperature Kit is not designed to work with the Bosch Therm C1210ESC or the C1210ES.

The Bosch Therm High Temperature Kit is bascially some instructions and a couple Jumpers.  The installation of the kit is very easy.  There are 2 small jumpers that will be inserted on the control board in the Bosch tankless water heater.

Installing the Bosch Therm High Temperature Kit:
*Make sure power to the unit is TURNED OFF!
1.  First remove the front cover of the heater.
2.  Then remove the screws holding the control unit on the bottom of the heater.
3.  Once the control unit is detached then you can access the back of the control unit and you will see a square cutout on the back and some pins where the jumpers will be inserted.  The pins are labeled JP5, JP6, JP7, JP8 and JP2 on the bottom.  Insert the 2 small jumpers from the high temp kit into pins JP7 & JP8.
4.  Double check connections and then screw the control unit back into place and put the front cover on.
5.  Turn the power back on and the heater should default to 120 degrees F.  You will now be able to raise and lower the temperature on the unit from 100 - 184 degrees F.  Please take into consideration that when the heater is set at say, 180 degrees that the unit will only be able to flow about 1.5 - 3 GPM depending on the heater you have.  The higher the temperature the lower flow you will get.

Bosch Therm External Water Filter

The Bosch External Water Filter (8703305356) replaces the internal water filter that comes with the heater. Having the water filter external means it is located under the Bosch Therm tankless water heater and is therefore easy to access and clean out. Odds are that if you do not install the external water filter then the internal water filter will not get regularly cleaned out as you would have to open the cover and remove the control board to get to the internal water filter, which is not very convenient.  It is recommended to clean the filter screen at least once a year for periodic maintenance.

The Bosch Therm External Water Filter is designed to work with the following Bosch Therm Tankless Water Heaters: C 1210 ESC, GWH C 920 ESC, C 1210 ES, GWH C 920 ES, C 1050 ES, GWH C 800 ES, C 950 ES, 940ES, 940ESO, GWH 715 ES, and 830ES.

This accessory is not included with these heaters and is highly recommended.

The Bosch External Water Filter is included with the Bosch Integra 500 and Bosch Evolution 500 water heaters.

The Bosch External Water Filter is NOT compatible with the new Bosch Greentherm C950ES and Greentherm C1050ES tankless water heaters.

Replacement filter screens part 8700507059 are available for the Bosch External water filter.  Please call us at 866-289-4652

New Greentherm PP Concentric up and out vent kit

New for the Bosch Greentherm C 950 ES & C 1050 ES is the polypropylene concentric up-and-out venting kit consisting of the appliance adapter, a 90° elbow, and a termination. This is the simplest and quickest venting option possible for a condensing tankless unit. The outer metal pipe and the inner polypropylene pipe make it both lightweight and rigid. The termination is telescopic to allow for varying wall thicknesses.

This new PP concentric up and out vent kit is approved for the New Green Therm C950ES & C1050ES tankless water heaters.  The PP concentric up and out vent kit is also approved for the Bosch Therm C950ES & C1050ES.  

Before attaching the appliance adapter to the top of the heater, a second metal plate comes with the kit and would cover the other intake air hole.  Then you would want to remove the exhaust collar from the top middle of the heater and then attach the appliance adapter as this will enable the heater to exhaust to the outside and also take its combustion air down the outer side of the same hole.

Bosch Greentherm PP concentric up and out vent kit (7738003210)

The Greentherm models C 950 ES & C1050ES are also approved for PP twin-pipe venting systems. Availability of generic PP vent pipe has increased and systems are becoming more popular due to ease of installation.  The twin pipe installation would be used if the customer needed to go out a different area out the sidewall or through the roof and would need to take the combustion air from the outside also.



New Bosch Greentherm C 1050 ES Condensing Tankless Water Heater

The New Bosch Greentherm C 1050 ES Condensing tankless water heater is a top performance, fully condensing gas tankless water heater from Bosch. This 199,000 BTU heater is designed for residential or commercial applications and can deliver hot water up to 140 degrees F with a 10.5 GPM flow rate.  Not approved for space heating applications.

This Energy Star approved tankless water heater can produce enough hot water for 2-3 major applications in most homes or is good for most commercial applications.  The Greentherm C 1050 ES is now 94% energy efficient.

Unlike traditional non-condensing models, condensing technology captures heat from the exhaust gas and uses it to preheat the incoming cold water. This increases efficiency and reduces emissions -- well ahead of the 2012 Low NOX emissions standards set by SCAQMD (California -- South Coast Air Quality Management District).  The Greentherm C1050ES now has NSF Certification (National Sanitation Foundation) for commercial kitchens.  The Bosch Green Therm C1050ES now has an added bypass tube connecting the cold and hot water lines inside the unit so the heater can mix a little cold water with the hot to alleviate and fluctuations and maintain a more stable temperature.  Standard now also are three NTC temperature sensors. With a new sensor immediately after the HEX, the Greentherm achieves benchmark temperature control. The NTCs are no longer clipped on, but rather installed into the inlet and outlet pipes.

The Bosch Greentherm C 1050 ES features an electronic ignition system and can vent through either 3 inch or 4 inch diameter PVC vent pipe either through the side wall or up through the roof.  The Greentherm C950ES now takes a new concentric venting system and attaches right to the top of the heater and takes its intake air and exhaust out through one hole to the outside.  The Greentherm C1050ES can now be cascaded together with up to 4 units and they can all vent into one pipe using a special venting kit to the outside.  Installation can be done venting up to 4 units together into the one pipe having the heaters mounted side by side or back to back.  The combustion air for the units will need to be taken from the inside of the building.

The Bosch Greentherm C 1050 ES comes with built in freeze protection.  The Greentherm C1050ES also comes with an external water filter screen.  The Bosch Green Therm C1050ES does not come with a 3/4" pressure relief valve, this is an accessory that would have to be ordered separately.

The freeze prevention kit is designed to provide protection for the water heater down to approximately 5°F for short term conditions only. It will not protect the appliance in areas where the temperature is routinely expected to be below freezing.  The freeze prevention kit will not protect plumbing outside the appliance from freezing.

The Bosch Greentherm C 1050 ES comes with a limited 15 year warranty on the heat exchanger and 5 years on all other parts.  Service and labor costs are not covered.

Bosch Protankless C800ES Condensing unit

The Bosch Protankless C800ES Condensing tankless water heater is a top performance, fully condensing gas tankless water heater from Bosch. This 199,000 BTU heater is designed for residential applications and can deliver hot water up to 140 degrees F with a 10.5 GPM flow rate.  Not approved for space heating applications.

This Energy Star approved tankless water heater can produce enough hot water for 2-3 major applications in most homes.

Unlike traditional non-condensing models, condensing technology captures heat from the exhaust gas and uses it to preheat the incoming cold water. This increases efficiency and reduces emissions -- well ahead of the 2012 Low NOX emissions standards set by SCAQMD (California -- South Coast Air Quality Management District).

The Bosch C800ES features an electronic ignition system and can vent through either 3 inch or 4 inch diameter PVC vent pipe either through the side wall or up through the roof.  A 3" PVC concentric vent kit is available for venting vertical or horizontal and allows the unit to be vented and also have its intake air from the outside through one hole.

The Bosch C800ES does not come with the built-in Freeze Protection kit but it is available as an accessory.  The C800ES also does not come with an external water filter screen but is also available as an accessory.  The Bosch C800ES does come with a standard 3/4" PRV.  The Bosch Therm C 1050 ES tankless water heater is about the same as the C800ES except that it comes with the freeze protection kit.    The Bosch Integra 500 is also about the same as the C800ES and the C1050ES and it comes with the freeze protection, 3/4" PRV and the external water filter screen.  All three tankless heaters are 199,000 BTUs and have the same temperture rise. 

The freeze prevention kit is designed to provide protection for the water heater down to approximately 5°F for short term conditions only. It will not protect the appliance in areas where the temperature is routinely expected to be below freezing.  The freeze prevention kit will not protect plumbing outside the appliance from freezing.

The Bosch C800ES comes with a limited 15 year warranty on the heat exchanger and 5 years on all other parts.  Service and labor costs are not covered.

New Bosch Tankless Universal Control Board

Bosch has released a new Universal Control Board (part number 87072073680) for their "World Two" tankless water heaters.

The board comes with three jumpers and instructions as to where to place those jumpers to make the board model-specific.

One jumper specifies if the heater is a 175,000 BTU or a 199,000 BTU appliance, another jumper specifies the gas type - NG or LP, and another jumper specifies if the heater has a surface-mounted outlet temperature sensor or is using a newer immersed sensor that is included on some recent production heaters.

Additionally, the world two universal control board is able to automatically determine if it is being used on a condensing or non-condensing tankless water heater.

This universal control board can be used on the following Bosch tankless water heaters for both natural gas and propane:

• C1050ES, C950ES, 940ES, 940ESO, 830ES
• C800ES, 715ES
• Integra 500, Evolution 500
• AquaStar 2700ES, AquaStar 2400ES
