HOT WATER CALCULATOR GUIDE Version 1 - GBCSA

Table 3: Boiler hot water system input data. In the case of dwellings with instantaneous gas boilers (i.e. no hot water storage), the rated/default recovery efficiency may be multiplied by a factor of 1.2 to account for the lack of storage heat loss. Instantaneous electric water heaters do not generally provide such a large

Sizing a Steam Boiler | U.S. Boiler Company

Dec 05, 2017 · Last month we discussed sizing a hot water boiler with a heat loss calculation. Unlike a hot water boiler, a steam boiler is sized by determining the square foot of radiation connected to the steam system. Once that's been determined, you can accurately select a boiler that's large enough to heat the connected load (radiation).
