Domestic hot water generation is becoming more important in many homes and commercial buildings today as occupants require generous volumes of hot water delivered in the most efficient way possible. Environmental awareness and sound economics is driving the need for more efficient and durable water heating solutions than those of the past.
Many traditional direct-fired storage type water heaters have efficiency ratings in the low 60% range as apposed to 90% plus for condensing boilers. As well, in many areas of the country, these heaters last less than 5 years due to mineral build-up, adding a big burden to our landfill and recycling facilities.
IBC Indirect fired water heaters use the hot water from an IBC boiler, diverted through a closed-loop heat exchanger coil in the tank, to heat incoming domestic hot water. The generous coil size allows us to operate the boiler at lower water temperatures so that we can take advantage of the energy gained through condensing operation of the boiler. Since the heat exchanger coil has a much cooler surface than the heat exchange surfaces of a direct-fired tank, mineral build-up is greatly reduced, resulting in a much longer service life. Made of stainless steel, our tanks are also very resistant to corrosion from aggressive water.
The deep modulation range of IBC boilers allow for very efficient, low level operation during the bulk of the heating season while having the instant availability of the higher output range for fast recovery of domestic hot water.
Well insulated, our water heaters can hold a large volume of hot water ready for instant use with minimal energy loss from the jacket. Unlike conventional water heaters, there is no chimney flue to act as a heat scrubber, further saving energy. Unlike the tankless-type heaters, our indirect approach offers sufficient delivery volumes for the most demanding loads - such as soaker tub fillers and "carwash-type" showers - with true instantaneous response times. For a comparative discussion of Indirect vs. Tankless DHW technologies, please refer to the attached.
Available in many sizes up to 120 US gallons, right sizing of the water heater allows end users to have as much hot water on tap as they want, whenever they want it.
