Heat Loss Concrete Floor

Electric systems if you are installing a concrete floor as part of a new build project our inslab cable system is an ideal electric floor heater choice.

Heat loss concrete floor.

The heat transmission through a building wall or similar construction can be expressed as. If i were building a new home i would install it in all my concrete floors. U overall heat transfer coefficient u value btu hr ft 2 o f w m 2 k. An uninsulated or under insulated basement floor is a major source of heat loss in the home.

It may be way too simplistic thinking to break that out of a complex software program and if so then so be it. If anyone can disclose how the fancy software programs do this i d love to know. Notice the styrofoam going up the edge of the slab to reduce heat loss. The first thing to consider when looking into different types of concrete floors is why it s so important to insulate the floor slab.

H t u a dt 1. I ve been dancing around this issue searching yakking etc and i still don t know how exactly to calculate heat loss out of a slab on grade. Why it s important to insulate a concrete floor in the basement. Check out this article for a list of slab edge insulation solutions and episode 125 for my interview with henry edney of maxraft.

This is one step i see left out of a lot of radiant installations. Although concrete is not a particularly good insulator heat loss or gain through a concrete slab is unlikely to be as significant as heat transmission through above. Concrete floors and heat loss. You can step onto a warm and inviting floor even one built on a concrete slab by adding in floor heating.

A wall area ft 2 m 2. Dt temperature difference o f k. Three key benefits of insulating the concrete floors in the basement are heat loss prevention moisture prevention and a higher level of comfort. H t heat flow btu hr w j s.

The heat retention properties of polished concrete make it an ideal floor finish for heating with a radiant floor heating solution. Finally i just found one heat loss estimation guide that puts the u value of concrete floors at a very modest 0 7 w m 2 c. It is probably illegal immoral too. The overall heat transfer coefficient the u value describes how well a building element conducts.

I do think concrete floor heat is a great way to go. While hot water and air based radiant heat systems require pipes being laid beneath the.
