Hydronic Concrete Slab In Floor Heating System

Mainly heated slabs radiate outward rather than downward so insulation on the edges of the slab is most important.

Hydronic concrete slab in floor heating system.

The system works via pex pipe a small pump a water heater and a thermostat. Hydronic slab heating turns your whole floor into a radiant heater producing that amazingly comfortable warm home that hydronic floor heating is known for. The most cost effective system for medium to larger homes is hydronic since the amount of power it would take to heat a whole home with electric would be substantial. The floor construction in that case is a 4 in concrete slab sitting on 1 in.

There s two basic types of concrete floor heating hydronic and electric. This is about installing hydronic radiant floor heating in a slab floor system. As warm water circulates through the tubing or as electricity warms the heating elements the concrete flooring turns into an efficient inconspicuous radiator. It has a lower required operating temperature than a panel radiator system hence is ideal for integration with a solar power source.

Pex tubing spaced 12 in on center. Typically radiant heating systems warm floors to temperatures of 75 to 80 degrees f. Digital non programmable thermostat for hydronic radiant floor heating quyoting. Like sand concrete is an ideal carrier of radiant heat because of its inherent thermal mass.

R 5 polystyrene insulation and covered by 3 8 in oak flooring. Radiant hydronic underfloor heating or slab heating is an efficient and comfortable form of central heating. Remember that your slab will be about 75 degrees f. D 508f digital non programmable heat only thermostat is designed to control either ambient air temperature a mode or floor temperature f mode or a combination of ambient temperature with floor temperature limits af mode.

In all you can expect to pay anywhere from 6 000 to 14 000 to install a hydronic radiant floor heating system. An auxiliary remote sensor is provided to measure slab temperature in order to control the floor temperature within maximum and minimum limits in af mode in hydronic radiant floor. Any cooler surface in contact with the slab will try to steal its heat. While it was done as a new house was being built in my last house i poured a concrete floor on top of a wood framed floor system and could have put radiant heat in that as well.

Embedding your radiant heating system into a concrete slab is one of the most cost effective ways to install it and most energy efficient being that concrete is a great thermal mass. This includes the system itself and the cost for a dedicated water heater or boiler generally 360 to 1 000 for a 50 gallon water heater or approximately 6 000 for a boiler. Due to it s density and low conductivity concrete retains heat very well. The cost of slab heating is usually around 60 00 per square metre based on a minimum area of 120sqm for a natural gas system.

If you will be using a concrete slab or basement slab it is important to utilize the exterior perimeter insulation as well as under slab insulation. The embedded tubing circuit consists of 1 2 in. This is the best choice for new construction and areas receiving new slabs.
