Boiler size actually refers to the output in kilowatts (kW), not the physical dimensions. A kilowatt is a unit that is used to measure how much energy is output by the boiler in the form of heat. Generally speaking, the more heat and hot water you require, the higher the output you will need although other factors also play a part in choosing the right size.

C orrectly Sizing a Steam Boiler-What do I need to know? The correct selection of a steam boiler output is critical to its operation, efficiency and performance. If undersized for the system load, then steam pressure will rapidly decrease thus causing the boiler to collapse its steam space, in turn causing low water alarms and ultimately burner lockout.

It's not height, width or depth that we're discussing, but rather its output in kilowatts (kW). The more power the boiler can generate in kWs, the bigger it is in terms of 'size'. For reference, let's take a look at our range of domestic gas boilers. Our combi models are available from 24 to 40kW; system from 15 to 32kW; and heat only

10/3/2010 · Step 2 – Adding Extras. Add the extras to this calculation to work out exactly how much hot water your boiler needs to produce to keep your radiators ticking over. You will have to add 35kw to each radiator in order to account for pressure switches and valves. You should then also add 10% to the total calculation to allow for very bad weather

There are three main types of boiler (combi, system and conventional), but within these types, there is a range of "sizes" that homeowners have to choose from. The size has nothing to do with the physical dimensions – they're all about the same within each type – it's all to do with the amount of energy they can put out into your heating and hot water system.
