Answers to most Frequently Asked Questions

Q: What happens when the concrete cracks?

A: The concrete cracking will have no effect on the tubing. Almost all concrete cracks to a greater or lesser degree. The only time the tubing will be effected is when the floor actually shifts causing a shear to develop which would rip the tubing. This occurrence is rare and can be prevented with proper reinforcement and ground preperation

Q: What size tubing should be used?

A: This depends on the size of the building. 3/4" tubing can be laid out in circuits up to 500' long. 1/2 tubing should be kept to around 250'/circuit. Therefore if the building is large such as a shop or warehouse, 3/4" tubing is used to save on manifolding and labor costs. In a smaller building or house 1/2" tubing is typically used because of the smaller rooms or area to be covered.

Q: What is the spacing of the tubing?

A: Typically 12" spacing is adequate, however in buildings or rooms with a high heat loss, closer spacing may be needed. In well insulated buildings a wider spacing may be acceptable.

Q: Can a water heater be used instead of a hot water boiler?

A: Water heaters can be used when the heat load is small such as in a small shop or home. When the BTUH heating requirement is around 100,000 BTUH though, it is generally more cost effective to install a boiler. A boiler is more efficient, will last longer, and has more safeties that a water heater.

Q: Why is floor heat so expensive when compared to forced air?

A: This initial expense of forced air is generally less, however, there are several factors which enter into this. The distribution of heated air in a building is accomplished by means of duct work strung through the floor and ceiling with the air coming out in a few places within a room or building. Floor heat utilizes the entire floor as the distribution system. If you are in a room that is 500 sq. ft. you in effect have a 500 sq. ft. heater. The components such as pumps, boilers, valves, fittings, tubing and other controls tend to be more expensive than forced air components. The reason for spending the extra money however include; Much greater efficiency than forced air (pay back of extra cost range from 3 to 10 years.), Much greater comfort. Because you are standing (siting, lying sleeping, working) on the heater, you will experience an extremely comfortable heating environment. Absolutely nothing even comes close to the comfort of a heated floor. More healthy environment. There is no blowing air or dust with a heated floor and it does not dry the air. Individual room control. This is easy to accomplish with a heated floor which means if you want your bathroom warmer than your bedroom, no problem. Not so with forced air.
