RELIEF VALVE You must have a relief valve on your boiler. Water expands as it is heated. If there is no place for the water to expand into, water pressure will build up inside the boiler and system. Should this happen, the relief valve will automatically open at a pre-determined pressure. This will relieve the strain on the boiler and system. Run a[...]

CIRCULATING PUMP Every forced hot-water system requires a circulating pump. A separate pump or zone valve is required for each zone, if you have a two or more zone system. This pump must have the capacity to provide the circulation required by your system. The pump is connected into the return main just ahead of the boiler. It is also wired to the [...]

HOW A HOT-WATER SYSTEM OPERATES Your entire heating system (boiler, piping and radiation units) is filled with water. As the water in the boiler is heated, it is pumped from the top of the boiler through the supply main to the radiation units. The cooler water in them flows back through the return main to the boiler. This provides positive and rapi[...]
