• If a circulator fails, heat is interrupted only to one zone. The other zones function as normal. Failure of the circulator in a zone-valve system will prevent heat delivery to the entire system. It is important to note that a springloaded flow-check valve must be installed in each zone of a multi-circulator system. If there are no check .

Gravity Circulating Heating System. In a hot water gravity heating system the circulation of water is a result of the density difference between hot water in the supply lines and cold water in the return lines.. The hot water tends to flow upwards and cold water tends to flow downwards. The elevation of the supply and return lines are therefore important for proper functionality.

Circulator pump - Wikipedia

Circulator pump - Wikipedia

A circulator pump or circulating pump is a specific type of pump used to circulate gases, liquids, or slurries in a closed circuit. They are commonly found circulating water in a hydronic heating or cooling system. Because they only circulate liquid within a closed circuit, they only need to overcome the friction of a piping system (as opposed to lifting a fluid from a point of lower potential .

How to size a Circulator Pump. Taco pump curves.

Since most of the radiant heating systems utilize a 20F temperature drop, the formula can be changed to: 1 GPM = 10,000 BTU/hr, meaning that for every 10,000 BTU's of heat load the circulator must output a 1 gallon per minute flow. Assuming that system calls for 100,000 BTU/hr, a circulator pump should have a minimum 10 Gallons Per Minute flow .
