And conversely, if you try to save money on a cheaper, lower-powered boiler for a large family, you'll probably find you frequently run out of hot water and have tepid radiators. That's why you need to calculate the size of boiler for your particular household, either for right now or for the near future, if you anticipate changes happening

Consequently the boiler is required to supply enthalpy to bring the water up to boiling point. Most boilers operate at pressures higher than atmospheric, because steam at an elevated pressure carries more heat energy than does steam at 100°C.

Use boiler horsepower to calculate steam flow. Boiler horsepower is not related to mechanical horsepower. It is a boiler industry rating that predicates the amount of saturated steam a boiler will generate starting with water at 212 degrees Fahrenheit and 0 pounds per square inch gauge (psig--meaning atmospheric pressure) and ending with steam at 212 F and 0 psig.

A hot water baseboard heater uses radiated heat from heated water to warm a room. Essentially, hot water baseboard heaters work the same as older cast iron radiators, except they take up less space. When you size hot water baseboard heaters, you are not determining the physical dimensions of the equipment; you are determining the required heat

Subtract the supply water temperature from the return water temperature to find the system temperature change. Calculate System Delivered BTU To find the system delivered BTU, multiply the BTU multiplier of 500 x the estimated Pump GPM x the System Temperature Change. Example: Say you calculate the pump pressure at 5.4 feet of head. Using the

The size of hot water tank will vary between houses, larger houses having larger tanks as it is assumed that the need for hot water is greater. For this exercise, a 120 litre tank is assumed. First a design reheat time needs to be established, this normal assumes that all the hot water has been used and the tank is filled with cold mains water.

2013-1-13 · We need a new boiler in our house and have had a lovely plumber calculate our Heat Calcs (heat loss?) for the house to be 34.87 kw. We have 3 bathrooms, but only use 2 of them unless we have guests (rarely!!) - my question is how do we calculate the hot water need in order to calculate the size of the boiler?
