How to Calculate the Proper Flow Rate for any Hydronic

Water is the way in which heat is distributed from the boiler room out to where the people are. How much water determines the flow rate and GPM. An accurate assessment of heat loss in a building is very important to establish the design load conditions. Once the load is established, then we can calculate the necessary flow rate. GPM = Heat Load
