The time required to heat 75 kg of water (c p = 4.2 kJ/kg o C) from temperature 20 o C to 75 o C with steam produced from a boiler with capacity 200 kW (kJ/s) can be calculated by transforming eq. 2 to t = m c p dT / q = (75 kg) (4.2 kJ/kg o C) ((75 o C) - (20 o C)) / (200 kJ/s) = 86 s

B oilers that use radiators or in-floor pipes to distribute heat are the most common type of heating system. Before designing a heating system you need to know the heating capacity and after that calculating boiler size .

Calculation By analysing the heat output on an item of plant using heat transfer equations, it may be possible to obtain an estimate for the steam consumption. Although heat transfer is not an exact science and there may be many unknown variables, it is possible to utilise previous experimental data from similar applications. The results

Once thatâ€™s been determined, you can accurately select a boiler thatâ€™s large enough to heat the connected load (radiation). You only need enough steam to fill the system; any more could result in short cycling.
