Using Bosch Tankless for Domestic Hot Water Recirculation


Bosch tankless water heaters can be used in recirculation applications and there are many different set ups for this such as direct recirculation and indirect recirculation.  Certain models of the Bosch tankless water heaters are approved for direct recirculation and are listed below.  Please be aware that the heat exchanger warranty of 15 years will be reduced to 3 years for direct recirculation.  This is stated in the warranty section of the installation manual.   All of the Bosch tankless water heaters can be set up for an indirect recirculation application in conjunction with a mini tank, recirculation pump and aquastat as described in the image below. The warranty for recirculation through an indirect mini-tank and not directly through the heater is 15 years.

Bosch tankless water heaters approved for direct recirculation:
Bosch Therm C1210ES
Bosch Therm C1210ESC (Commercial Unit)
Bosch Greentherm C1050
Bosch Greentherm C950
Bosch Therm 940ES
Bosch Therm 830ES

New Bosch Tronic 3000T ES Mini-Tank Water Heaters

Bosch has rebranded the Ariston Pro Ti line of electric mini-tank water heaters. They are now labeled as Bosch Tronic 3000T ES Electric Mini-tank Water Heaters.


The old Ariston Pro Ti models GL2.5Ti & GL2.5TiS are now the Bosch ES 2.5.
The old Ariston Pro Ti models GL4Ti & GL4TiS are now the Bosch ES 4 .
The old Ariston Pro Ti models GL8Ti & GL8TiS are now the Bosch ES 8.

The new Bosch ES2.5, ES4 and ES8 electric mini-tank water heaters are the same size as the mini-tanks that each replaces.  The replacement parts for the new Bosch ES2.5, ES4 and ES8 are different now and will not work for the older Ariston GL2.5Ti, GL4Ti or the GL8Ti.

*  Please note that the new Bosch ES4 is not a direct replacement for the retail model Ariston GL4 as the Bosch ES4 is 13 1/2" in depth and the retail Ariston GL4 is 12 1/4" deep.

The new Bosch ES2.5, ES4 and ES8 have many new improvements since they have been upgraded. The mini tanks have 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 models you would have to remove the grey oval cover to access the temperature control knob.

The Bosch ES2.5, ES4 and ES8 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 heating element so the heater can adjust temperatures quicker and maintain a more consistent heat.

The new model ES8 now has to be hard wired to a plug for 110V.  Global Protankless Supply carries 6' cords for the Bosch ES8 heater.

7 Ways to Heat Domestic Hot Water with Bosch Products

Are you looking to heat your domestic hot water (DHW) for your showers, sinks, dishwasher and washing machine? If so, Bosch offers 7 different ways to achieve this goal in highly efficient ways! This blog entry provides a detailed comparison of the different ways Bosch can help you heat your DHW.

1) Bosch Therm gas and propane condensing tankless water heaters. Bosch offers several models of condensing tankless water heaters ranging from 175,000 BTUs up to 225, 000 BTUs. These electronic-ignition tankless water heaters have a secondary condensing heat exchanger that reclaims heat and redirects this heat back to the water thus reducing the exhaust temperature. As a result the exhaust temperature is cool enough to be exhausted via 3" or 4" PVC or CPVC piping. These heaters are generally about 92% efficient and can produce enough hot water for 2 to 3 showers at a time, depending on where you live.

2) Bosch Therm gas and propane non-condensing tankless water heaters. Bosch offers several models of non-condensing tankless water heaters ranging from 75,000 BTUs up to 199,000 BTUs. On the higher end from 175,000 BTUs up to 199,000 BTUs the Bosch tankless water heaters have an electronic ignition and require special 3" or 4" stainless steel venting. These heaters are about 82% efficient and are a great solution for most families. On the lower end the heaters range from 75,000 to 117,000 BTUs and have either a standing pilot light or use Bosch's patented Hydro Ignition system. These heaters are perfect for "off-grid" installations or areas with frequent electricity outages. In the mid-range Bosch offers both indoor and outdoor electric-ignition 140,000 BTU heaters that require 3" stainless steel vent pipe.

3) Bosch Tronic electric tankless water heaters. The Bosch Tronic line of electric tankless water heaters are available both in whole-house models (Tronic 5000 Series) or in point-of-use models (Tronic 3000 Series). Both the Tronic 5000 and 3000 Series heaters are tankless and will produce endless hot water. Be sure to verify that your electric supply meets the minimum requirements for these heaters. The Amperage is the key.


4) Bosch Ariston Pro Ti electric mini-tank water heaters. The Ariston Pro Ti line of mini tanks range from 2.5 gallons up to 7 gallons. Like a regular hot water tank, these mini-tank heaters keep water hot and ready for use in highly efficient glass-lined tanks. These heaters are perfect for point-of-use applications, but will generally be insufficient for showers. The heaters plug directly into a 110 wall outlet and draw only 12.5 Amps.

5) Bosch Compress 3000 HP 200-1 heat pump. The 50 gallon Bosch Compress heat pump is a great addition to the Bosch line of domestic hot water heating products. This ultra efficient water heater uses technology similar to an EnergyStar qualified refrigeratorRather than taking heat from the inside of the appliance and moving it outside as a refrigerator does; the Bosch heat pump technology takes heat from outside the appliance and uses it to heat the water!


6) Bosch Greenstar Combi Boilers. Bosch offers two Greenstar Combination ("Combi") boilers ranging from 100,000 BTUs up to 151,000 BTUs. Each of these two Combi boilers can heat hot water for space heating as well as provide for a domestic hot water loop. These wall-hung, gas-fired condensing boilers are highly efficient. They come ready for natural gas and include a kit to swap over to propane use. Heating DHW with a Greenstar Combi boiler is perfect for homes that require hot water for their space heating needs.


7) Bosch Greenstar Boilers with Indirect Tanks. The Bosch Greenstar lineup of space heating boilers includes four gas-fired condensing boilers ranging from 57,000 BTUs up to 151,000 BTUs. Heating DHW with a Bosch Greenstar space heating boiler is simple when used in combination with a Bosch SST Stainless Steel Indirect Storage tank. Bosch offers four models of indirect storage tanks ranging from 40 gallons up to 119 gallons. The boiler heats a coil that runs through the indirect storage tank which in turn heats the potable water in the tank. 


With seven different ways to heat DHW, Bosch offers a solution for just about any application or need.
