Yes, but check with your local code enforcement department (some require boilers only) and make sure your water heater is sized correctly for the area you are heating. Set the water heater temperature control to high and make sure to install a thermostatic mixing valve and expansion tank.

There are many variables that dramatically affect heat loss, but here are some general guidelines, based on a new construction radiant slab, well insulated (walls, ceiling and under slab), in a moderately cold winter climate area using a thermostatic mixing valve: A standard 50 gallon electric water heater with (2) 4500 watts elements and a 20 gallon per hour (gph) recovery rate can usually heat about 250 sq ft.

We have had good luck with the Polaris, but it does require competent installation. You should have a competent gas man do the work. This is not a good do it yourself project. Some people should have been given their money back instead of getting a new Polaris, because the problem is at the site. See similar questions...

We have provided a heater specially designed for iPool. It includes a heater, a filter pump (1000gal/hr), and connector. The heater is optional for iPool, the cost is $600 plus $60 shipping and handling fee. Please click iPool Heater for more information. See similar questions...

Most water heaters are only in service for 2-3 hours per day and they often have enough capacity to do extra work. If the BTU heating output of the water heater is equal to or greater than the heating load, you can probably use it to heat as well. Look at the label on the heater for the BTU output.

Cork is a natural insulator so just by having a heated house; the floor will draw the warmth. If you still want to install radiant heat, it has posed no problems. The floor may take slightly longer warm up but the heat will be retained efficiently. Only floating floors should be installed over radiant heat systems. Floating floors tend to go through normal contraction and expansion as a unit since they are not attached to the sub-floor. See similar questions...

A sulfurous or rotten egg-like odor in the hot water is caused by bacteria growing in the water heater. This usually happens when the water heater is turned off while on vacation, when the hot water has not been used for a long time, or when the temperature setting on the heater is set too low. The bacteria in the water heater are not a health threat; however, they must be eliminated to stop the odor problem. The procedure for eliminating the bacteria is called heat disinfection.

Yes. There are different manufacturers and different methods, but it has become more and more common this past decade. See similar questions...

Vanguard has tested and approved glycol for use in Pex tubing, and recommends a 50/50 glycol/water mix for maximum freeze protection. Typical automotive antifreeze is not recommended due to the many additives in automotive antifreeze, which have not been approved for use with Pex. See similar questions...

All solar water heating systems deliver both higher temperature water and more water volume than conventional water heaters. They heat typically 40 to 80 gallons more water than conventional water heaters. See similar questions...

Only in areas subject to temperatures below 40 degrees for three or more days in a row. Water in the bio tanks should be kept at above 60º degrees F., 70º F. and above is ideal. See similar questions...

Most floor coverings can be used over a hydronic heating system, keeping in mind that the system is designed for that particular covering. Tile is the most efficient, since it is the most conductive. Hardwoods come next and then carpet and pad. Even vinyl or linoleum can be used. Typically the only design variance between these three common floor coverings is supply temperature.

Low-voltage radiant heat is safe, reliable, efficient and long-lasting solution to your floor warming, space heating and snow melting needs. High-voltage systems, on the other hand, have much shorter warranties (5-7 year average) and typically don't last as long. The high-voltage current wears out the carbon based heating element. The durable bronze ZMesh has an industry leading 25 year warranty and the low-voltage current has almost no detrimental effect on it. See similar questions...

If you want radiant heat and air conditioning, we recommend installing a distribution system for air conditioning within the ceiling and radiant heat tubing within the floor. Combining a forced hot air heating system and an air conditioning system utilizing floor registers is a less comfortable, dustier, and more expensive alternative than using two separate systems.

The tankless water heater could be used in a radiant system, provided that the incoming/returning water temperature will be less than 100 F degrees. Please consult with the manufacturer of the radiant system to determine the suitability of a tankless water heater with that particular radiant system. See similar questions...
