Hot water flow rates and combi boiler power - Ian

Handy rule: multiply the hot water flow rate in litres/minute by the temperature rise in celsius. Divide by 100 and multiply by 7 to get the boiler DHW output in kW. Example: 12 litre/min at 40C rise: 12 x 40 = 480. 480/100 = 4.8. 4.8 x 7 = 33.6kW boiler DHW output.
