Troubleshooting a Gas-Fired Hot Water Boiler

Jan 15 2021 · A boiler is a bit more complex than a forced air furnace in that it has more parts valves and controls. However gas-fired boilers are fairly reliable and when problems do occur they are usually related to the expansion tank or water circulation pump(s). The major components of the boiler for a hot water (hydronic) system include:

How to size a Circulator Pump. Taco pump curves.

Assuming that system calls for 100000 BTU/hr a circulator pump should have a minimum 10 Gallons Per Minute flow rate at a given pressure drop. For snow melt systems with a 50/50 mix of glycol and water the above equasion is slightly different: 1 GPM = 11000 BTU/hr The next step is to calculate the head loss or pressure drop in the system.
