The allure of radiant heat is the absence of loud steam radiators, vents blowing pockets of air, and the dust accumulation of ductwork. In essence, radiant heat turns entire floors into radiators creating an invisible blanket of heat in the area you want it.
Hot water is pumped from a heat source (typically a boiler) and distributed through a loop of flexible tubes buried underneath the floor. In hydronic systems hot water circulates from the boiler or water heater through loops of flexible tubing. These tubes can be installed (1) on top of the subfloor in grooved panels or snap-in grids; (2) clipped into aluminum strips on the underside of the floor; or (3) embedded in poured concrete. Once the system is in place, you can cover it with most types of finished flooring, including hardwood and tile. Carpet, however, can be tricky, especially if it has thick padding underneath.
Although hot-water radiant may cost more to install than other types of heating systems, as a separate air-conditioning system for cooling will be needed, once up and running the radiant system may be up to 30 percent more efficient than forced heating (dependent on how well your home is insulated).
In contrast with a conventional forced-air heating system, air blows out of the registers, rises to the top of the room where it quickly sheds heat, then drops back down as it cools. This can leave your head bathed in warmth while your bottom half is left cool. Secondly, there is the issue of cycling. In forced-air the hot air reaches temperature and the air is pumped out of the registers however when the hot air stops pumping out of the register it can leave you with sense of coolness due to the lack blowing air.
Radiant heating involves multiple components and no one manufacturer supplies all, it takes a skillful and expert heating contractor to put a system together, if you are interested in more information please contact Amhac Sales Department.
