The Definitive Guide to Condensing Water Heaters or Boilers

Feb 08, 2019 · In summary, for optimal operation, condensing boiler systems need the return water temperatures well below the dew point of the boiler exhaust (for natural gas, this is around 140°F in the Bay Area and 125°F in Denver), ideally around 80°F or lower. Non-condensing boiler systems require the return water temperatures to be above the dew point of the boiler exhaust (hence the warm-up loops).

MYTH #1 – WE NEED TO MAINTAIN 180°F HOT WATER SUPPLY FOR THE SYSTEM TO WORK Prior to condensing boilers, it was common for systems to be designed with high hot water supply temperatures in the range of 180°F to 200°F. One of the main purposes of the high hot water temperature was to satisfy the hot

Condensing boilers - heating hot water - timed or

As hot water is drawn out of the tank, it is refilled with cold water. The electronic controls monitor the water temperature and reheat the tank when necessary. The primary difference is that the high-efficiency condensing gas tank water heaters are designed to transfer and retain more heat into the water than a standard gas water heater.

1 Simple Trick to Get the Most Of Your Condensing Boiler

Jun 01, 2013 · Condensing boilers, while commonly installed for heating hot water applications, often fail to deliver their inherent efficiency advantage because of deficiencies in the system design, start-up, and operation. Condensing or "high efficiency" boilers are constructed to allow them to operate with lower water temperatures than traditional boilers.

A standard hot water supply temperature for a condensing boiler should start at a minimum of 140°F with the ability to go lower, provided enough heating capacity is available at a reasonable cost from the heating coils and terminal units. Although a lower water temperature may be possible, there is a point where the increased first cost for

Measure Guideline: Condensing Boilers - Control Strategies

Dec 16, 2013 · By designing hot water supply and return water temperatures lower than conventional designs, it is possible to increase the efficiency of the boiler as more water vapor is condensed from lower hot water return temperatures and more energy is recovered that would otherwise be discharged out the flue, providing an efficiency increase of approximately 10% to 12% compared to noncondensing boilers.
