Underfloor Heating Systems

AHC are the leading installers of hydronic underfloor heating systems in Hamilton and the Greater Waikato. Underfloor heating offers a number of advantages over conventional heating methods such as, forced air systems, convection heaters and wood stoves. These traditional heating methods tend to produce an uneven heat with the highest air temperatures being at the ceiling or closest to the source. Heating is restricted to the immediate room area.

How Underfloor Heating Works

Hydronic underfloor heating systems heat through special tubing laid into the concrete foundation of a building. Heated water circulates through this tubing which in turn heats the mass of concrete and radiates up through the floor into the building. Heat is gently drawn up into the room. As it rises, there is even temperature throughout the room and superior comfort throughout the entire building. As energy is not wasted, fuel bills are cost-effective.

Factors to Be Considered

Factors to be considered are the heat source that suits your system needs, the type of floor coverings to be used and the areas to be heated. The aim is to achieve maximum results for minimal cost. What is Radiant Heating? An efficient form of heating, radiant heating supplies heat to your home, office or business using the simple method of air passing over hot water. This method of heating is typically delivered in two forms, underfloor heating and hot water radiators.

Underfloor Heating Options

We offer a wide selection of options - air-to-water heat pumps, natural gas boilers, diesel and solid fuel boilers. Advancements in technology are making these sources increasingly more efficient, ensuring that you don’t get left out in the cold. AHC can help you to choose the best heat source to meet your particular requirements and ensure on-going comfort at minimum cost.

When to Install Underfloor Heating

Underfloor heating needs to be considered before the building process begins, preferably at the planning stage.
