Have you ever gone on a ski vacation for the weekend and stayed at a little ski lodge? A lot of the times, they’ll have a huge fireplace in the main room with smaller bedrooms up in the loft area or second-story. But the problem is that when you’re in the main room with the roaring fire, you’re often overwhelmed by the heat and retreat to the bedroom, where it’s far chillier. You see, many vacation or weekend homes weren’t built with air conditioning ducts with which to deliver the heat to the different rooms of the house. However, there is a solution to adding heating to homes that have not been built for traditional forced air systems: radiant heaters.

As opposed to warm air systems (such as a forced air unit heaters), radiant heaters deliver the source of heat to the floor level, not the ceiling. Radiant heaters or radiant energy is the oldest form of heating used to provide comfort and is the basis for all heating systems.

Additionally, radiant heaters also offer more comfort than forced air heating by heating the atmosphere from the ground up. Since heat rises, the heat will be more evenly distributed, providing a much more comfortable atmosphere.

Radiant Heaters Tip: Radiant energy is totally pure radiation and is absorbed by an object without physical contact with the heat source or by heating the surrounding air, as is the case with convective, forced air systems.

The Mystery Warranty

How much do you really know about the warranties offered by manufacturers? Sure it may say “25 Year Warranty” on the package, but what exactly does that mean? Most manufacturers of radiant heating systems offer a warranty, but a 25 year warranty isn’t always better than a 10 year warranty and this is why:

I chose the Danfoss GX electric radiant heat cables to build an asphalt heated driveway at my residence. The heat of the asphalt combined with heavy weight, caused me to wonder how the GX cables were going to hold up, and what would happen if a problem occurred. I was pleased to discover that Danfoss products have a 10 year warranty, that covers up to 5 times the cost of original installation. Why is this exciting? Because the failure of a radiant heating system isn’t like a vacuum cleaner breaking down, you can’t throw it in your car and bring it back to the store for a refund. Fixing a severed cable requires tearing up the surface of the driveway – or in the case of indoor radiant heating, tearing up your brand new tiles or wood flooring. The process of tearing up a floor or driveway is time consuming and costly, not to mention annoying. Many manufacturers will replace the bad product, but you still have to pay out of your own pocket to tear up the floor and hire someone to fix the problem.

Danfoss is so sure that you won’t have any problems, their warranty is the best offered by radiant heat manufacturers. Not only do you get brand new Danfoss product, but they will cover the cost of floor removal, and reinstallation (up to 5 times the cost of the original installation). So when you install your radiant floor or driveway, you can rest easy knowing that unexpected problems are already covered.

Danfoss offers a myriad of cables for all kinds of projects, but figuring out the differences can be pretty tricky. I won’t go into technical details here, rather go over some basic differences that will help you choose which cable to use for which project.

All of the Danfoss products give you the option of choosing between individual cable in lengths (it comes on a roll) or in woven mats, which has the cable rows pre-spaced and makes installation much quicker and easier. The only difficulty with the radiant mats is that it works best with rectangular areas; however, the mat can be cut to accommodate corners and custom layouts. (Just don't cut the heat cable!) If you have a complicated, odd shaped area to heat, you may be better off with installing the individual heating cable.

Radiant Heaters Tip: Many people waste a lot of energy by not sealing cracks, doors and windows; checking to make sure a home’s insulation is in good shape and replacing it if it’s not is another good way to stop energy waste.

Radiant Heaters Tip: Radiant energy is totally pure radiation and is absorbed by an object without physical contact with the heat source or by heating the surrounding air, as is the case with convective, forced air systems.
