How is a circulator used in a radiant heating system?
Heating circulator pumps or “zone circulators” are used to force hot water from the heating boiler through radianting devices such as hot water baseboards or radiators. The circulator is switched on as needed or in some designs may be wired to run continuously.
Can a baseboard heater be used with radiant floor heating?
You can use baseboard heaters with any type of flooring, including carpeting and hardwood, without worrying about the source. Radiant floor heating is a more expensive option because of the labor needed to install the system and ensure it is properly anchored to the existing subfloor.
How much does a radiant floor heating system cost?
A high-efficiency boiler system costs on average $4,000 along with a hot water heater or x-block that run between $1,000 and $3,000. The installation cost will vary depending on the amount of labor required. Expect to pay between $50 and $70 an hour for installation. On average, hydronic radiant heating systems cost between $6,000 and $14,000.
How are circulator pumps used in a home heating system?
Also see ZONE VALVES, HEATING – home. Even a single zone heating system might use two circulator pumps. In this case the second circulator is being used to control a separate indirect-fired water heating system to provide domestic hot water for washing and bathing. See INDIRECT FIRED WATER HEATERS.
Which is the best circulator pump for radiant heat?
The heating load of a building is dependent on factors such as outdoor temperature and thermostat setting. Variable speed pumps are best for zone valve systems with a one system circulator. They are also ideal in radiant heat systems that use manifold actuators with multiple zones on a single manifold.

Is the circulator pump running on my radiator?
The circulator pump may be running but baseboards or radiators don’t get hot enough.
What kind of foam for radiant floor pump?
I put down R-10 rigid foam insulation, four zones of 1/2″ tubing, 300′ long each. The concrete is 3″ thick over the tubing. The tube spacing is about 11″, and I ran the tubing around the exterior perimeter of each zone before looping back through the interior of the zones. The edges are insulated with foam as well.
