It circulates water in the cooling pipe of the furnace when starting the operation and at low load and always maintains the flow in the pipe approximately at a fixed speed.

Troubleshooting a Gas-Fired Hot Water Boiler

Modern boiler systems for home heating are hydronic systems, in which the boiler heats water for circulation throughout the house.They are closely related to steam boiler systems, but rather than circulating actual steam, hydronic systems have pipes carrying the hot water that radiates heat through either steel radiators or baseboard convectors (sometimes called "fin-tubes").

The water is evaporated in this boiler within a hermetically closed cir-cuit. The steam flows to the heat exchanger and the condensate flows by gravity back

plumbing - Should a circulator pump be installed on the

Water pumps pump water, not air, so putting it on supply side makes water allways available for circulator to pump. If you put that circulator on other side it could be hard to fill system with water and avoid air pockets. And basicly you can't pump air with water pump as it makes them break.

Close the water cock side, the water connection is clear. Close the drain cock. Open the water cock, water should then gradually come rise up to the top of the gauge glass. Open the steam cock, the water in the glass should fall to the level of the water in the boiler. Why need to blow down the boiler water ?

The National Board of Boiler and Pressure Vessel Inspectors

Typical industrial boilers are "natural circulation" boilers and do not utilize pumps to circulate water through the tubes. These units rely on the differential density between hot and cold water to provide the circulation. As the water removes heat from the tubes, the water temperature increases and it rises to the boiler steam drum.
