Dual Purpose Water Heater

Accessories 

Three capacities - 99,000 , 120,000 and 199,000 Btu/h are available.

These units have efficiency levels of 90% AFUE on the heating operation and an energy factorof up to 0.85 for DHW production.  These outstanding efficiency levels are achieved by utilizing two heating exchangers, including a wet recuperative heat exchanger.  This heat exchanger condenses extra energy from the hot flue gas to provide additional performance and energy.These units are capable of being vented in Schedule 40 PVC.

Innovative Design

Our innovative Heat Exhanger design flows the flue gas in  "S" line configuration to improve heat transfer & unit efficiency.

S Line Heat Exchangers

The S Line heat exchangers have our innovative design.  Placing the
latent heat exchanger at an angle above the sensible heat exchanger
ensures complete separation from condensate, increasing unit
longevity.

Flue gas flows upward providing stable & quiet operation even with up
to 45 ft equivalent flue lengths. 

The design of the latent heat exchanger reduces flue gas temperature
to below 140 DegF at all times, allowing the use of Schedule 40 PVC
as the vent material. 

 

Modulating Gas Valve

The modulating gas valve allows complete control of the gas flow to the
burner assembly. This unit has a turndown ratio of 2:1 to provide
performance across a wide range of heat loads.

 

Durable Hydroblock

To increase efficiency, reliability and service a modular concept is used to
mount all of the components controllingheating and DHW flow directly to
the DHW heat exchanger.

 

 

Easy to Use Unit Controller (DSR-100F)

Each unit is supplied with a unit controller allowing both the heating water temperature and the Domestic Hot Water temperature to be set by the end user.

Heating water temperature can be set from 122 DegF to 179 DegF and DHW temperature from 98 - 114 DegF, 120, 130, 140DegF.  (Quietside recommends the installation of an anti scald valve on the DHW system).

The unit controller will also display fault codes in the unlikely event of a malfunction ocurring with the unit.
