Radiant Heating & Specialties
The benefits of radiant heat flooring are that it is silent, cost-efficient and practically maintenance free. Homeowners who use radiant heat also claim that the heat produced is exceptionally comfortable because there are no layers of air in the room that are warmer or cooler than any others. Though radiant heat is more expensive to install than traditional forced-air heating, it makes up for it in energy savings over the years.
The options related to this kind of system are endless. Looking to cut down on the cost of installation? We can pipe just one zone of radiant into the master bath, kitchen or both. Then we would tie the boiler into an air handler.
The air handler is a ducted system for forced hot air with a coil for air conditioning. Our state of the art boiler pipes right to it and would heat the entire house. The installation is cheap and adds the benefit of air conditioning.
