In my opinion, the undoubtedly best type of boiler is radiant heated flooring. There is no comparison to the benefits provided by this particular innovation. While there are electric mats that can be retrofitted quite particularly into an existing home, I would like a hydronic system. It starts with a boiler that heats up water & pumps it through a series of pipes concealed under the floor. Utilizing water rather than air to move heat energy ensures quiet operation, eliminates energy waste & provides a more gentle form of comfort. Because the pipes create a closed loop, using the same water over & over, there is no occasion for contaminants to enter the system. Boilers are often advocated for people who suffer asthma, dust sensitivities & respiratory infections because of the cleanliness. The heat from the pipes spreads evenly across the surface of the floor. There are no cold spots in the corners & no drafts. Everything sitting on the floor, such as tables & chairs, are warmed up & help to further radiate heat. The temperature from floor to ceiling never varies more than three degrees from the thermostat setting. The machine takes up no residing space & doesn’t require furniture to be arranged to accommodate it. It doesn’t create an eyesore or make any noise. Plus, radiant floor allows for the easy set up of zone control. A thermostat in each room provides independent temperature control. This caters to room occupancy, requirements & preferences & helps to trim running costs. Radiant flooring is attractively energy efficient & saves money on monthly energy bills.
