Hot Water Boilers in Ohio, Kentucky and Indiana | Lathrop

Hot Water Boilers. Hot water boilers, also called hydronic boilers, supply energy for a variety of facility operations. They are most commonly used in heating and process applications, supplying water at temperatures of 130F to 200F. If a system requires temperatures greater than 240F, a high-temperature hot water boiler can be specified.

Boiler Flow Rates (Why Mains Pressure Matters) | Combi

Now take the volume of water in the jug, in litres, and multiply by 10. (eg 0.9 litres x 10 = 9 litres per minute). Anything below 10 litres per minute is considered low pressure. A reading between 10-15 litres per minute is average and a flow above 15 is considered good. Once you have established your mains flow rate, it's simply a case of
