What is a boiler flow rate and how does it affect my hot water supply? When manufacturers & installers talk about water heaters, especially combi-boilers, a key phrase used is "flow rate". In most cases this is really referring to how much water can flow through the boiler & how fast it can come out of a tap or shower head once the boiler is working.

Get A QuoteA reasonably well-insulated shell or water-tube boiler of 5 MW or more will lose between 0.3 and 0.5% of its energy to the surroundings. This may not appear to be a large amount, but it must be remembered that this is 0.3 to 0.5% of the boiler's full-load rating, and this loss will remain constant, even if the boiler is not exporting steam to the plant, and is simply on stand-by.
