Boiler Circulator Pump – Hydronic Components


Boiler Circulator PumpBoiler Circulator Pump – The boiler circulator pump induces the flow of hot water through the boiler and the boiler loop. Usually the boiler circulator pump is controlled by the aquastat however there are various levels of control that can be found that control pumps. One way is by the aquastat as mentioned above. Another way is by an end switch in a zone valve. A thermostat in a particular zone will call for heat and the thermostat calls for the zone valve to open. When the zone valve is fully open an end switch closes the circuit to energize the circulator pump. Typically, the circuit is a control circuit so when the end switch closes it closes the circuit for a relay to energize the circulator pump

Boiler Components: Aquastat Temperature ControlThe boiler aquastat controls the temperature of the water inside the boiler jacket. The boiler aquastat is a device to a boiler like a thermostat is to an air conditioner, heat pump, or gas/oil furnace. The boiler aquastat controls the temperature inside the boiler just as the thermostat controls the temperature for an air conditioner or heat pump. The boiler aquastat will turn the burners on and off and also controls the circulator pump on a hot water boiler system.

HVAC Tips: Helping You Learn

According to studies done by the Department of Energy, 50 percent of the heat loss experienced in the average home occurs through the ceiling. That makes a lot of sense since heat rises. You can reduce that heat loss (heat gain in the summer months) by adding another layer of insulation in the attic. That will hold more heat in our homes for a longer period of time which means the furnace will cycle less. That means you are going to save money. A lot more money than another layer of insulation costs. Additionally, having an attic fan controlled by a thermostat installed in your attic will remove a lot of heat in the summer. This will help you, in addition to having more insulation, reduce heat gain from the attic in the summer.
