For boiler sizing there is a relatively simple yet sufficiently accurate calculation known as the whole-house boiler sizing method. The method is described in the Energy Saving Trust worksheet (PDF) An online calculator implementing the method is available at: IDHE (Institute of Domestic Heating & Environmental Engineers) calculator DEAD LINK 4

Pump Flow Rate. Condensate pumps are typically sized at three times (3x) normal condensing or evaporation rate. These guidelines are based upon design and operating experience. However, upon proper application, units can be sized at two times (2x) the condensing or evaporation rate. Enter the load. Condensing or evaporation rate factor.
Condensing Boiler. This is a design of boiler which can have an increased efficiency over the more traditional boiler. The efficiency of a typical non-condensing boiler is around 75%, whereas with condensing boilers it can be over 87%. This increased efficiency is due to the extraction of heat from the otherwise wasted flue gases.
Aug 18, 2014 · Determine Pump Head & Select Pump. Given that our recirculation line is 300 feet in lenth, and our flow rate is 1.9 gpm (rounded up), we must calculate the total friction loss: Pipe pressure drop = 300 ft. x 1.4/100 = 4.2 ft. Check valve pressure drop = 1.0 ft. Supply Pipe (negligible) = 0.
Feb 01, 2010 · A condensing boiler was designed to be more efficient than a conventional boiler. It achieves this by reducing the temperature of the flue gasses where latent heat is released rather than escaping with the flue gases. In order to accomplish this, a condensing boiler will use either an extra large heat exchanger or a second heat exchanger.
Feb 01, 2009 · conventional boilers and comply with their operating limitations, then the maximum benefit to be achieved by the condensing boilers may not be realized. In both cases, success is dependent upon a system configuration and control strategy that will protect the conventional boilers while leveraging the condensing boiler benefits.

System boilers and conventional boilers preheat hot water to be stored in a hot water cylinder and therefore hot water flow rate is not as critical. The heat load for an average home can vary from around 10 kW to 20 kW, which means that system boilers and conventional boilers can be sized lower than combi boilers.
