Answers to questions on Radiant Floor Heating

Sometimes we get calls or questions about radiant floor heating systems, and I thought I'd cover a few of the most common inquiries here.

First of all, radiant floor heating comes in two varieties - either an electric heating cable is set into the mortar under a tile floor, or there is a piping system through which hot water travels, heating the floor and objects above.

In regards to cost, a radiant floor heating system is going to be more expensive at the outset. For one thing, you have a higher labor cost, because it has to be installed as part of the flooring system, and followed by a tile or other flooring installation. But as an offset to that cost, a radiant floor system tend to run 20 to 40 percent more efficiently than a standard forced air furnace, and it does add to the resale value of your home. For most people when you consider the added comfort provided, those benefits outweigh the initial expense.

Yes, you can still use air conditioning with radiant floor heat, and the two work quite well together. Radiant floor heating can be used to heat the whole house, or just a few selected floors, often the master bath and bedroom.

Installation is typically a two-person job. Be sure to use a contractor who is not only familiar with installation procedures, but has actually performed several successful installations. Because Radiant Floors are less common, it's worth checking to make sure your contractor has experience with these. All QualitySmith Contractors have the experience and customer recommendations needed to pass QualitySmith standards.

The hotter it gets the better it works

It almost sounds like a contradiction, but solar-powered air conditioning makes use of an absorption chiller to convert heat into a thermal reaction that cools water pipes that in turn are used to cool airflow.
The system still uses energy for pumping the water, running the fans, and keeping rooftop mirrors aimed at the sun, but it's a step in the right direction.
Another similar rooftop mirror-based system is being developed at Southern California Gas Co. and it's parent company, Sempra. Both systems are experimental, and both make use of an absorption chiller to convert hot water to cold water.
Sempra Energy has a strong record of pioneering solar energy projects.
