Hydronic Underfloor Heating
Hydronic heating uses hot water to provide whole home heating. If used wisely, it can be an economical and highly effective form of central heating. In most hydronic systems, the water is heated in a boiler, and then pumped through piping to panel radiators or convectors positioned in each room. Heat is transferred directly from these to the room air. In-slab (‘floor coil’) systems are also available. In these, the heated water is pumped through piping laid in a concrete slab floor during its construction. Heat is released into the slab, and subsequently into the room.
What are the advantages of Hydronic Heating?
- Individual control valves to each panel allow individual rooms or zones* to be heated independently, enabling running costs to be substantially lowered.
- Panel radiators can provide effective heating for rooms with higher ceilings (details on which radiator types are suitable for areas with high and low ceilings are discussed over the page).
- There is no dust circulation and air movement with silent radiant heat distribution (unless using fan convectors).
- Flexibility as further radiators or convectors can be added to a system as required, provided there is adequate boiler capacity.
- Response time is generally good, and you will feel warm within 30 minutes.
- Low maintenance requirements.
- The proven effectiveness of hydronic heating—it has been widely used in Europe for almost a century.
- There is an extensive range of radiator sizes to meet all heating requirements with attractive panels, top grills, and side covers. Thermaboard skirting board convectors can take the place of a skirting board and are available in rolled edge and traditional styles.
- Hydronic heating is environmentally clean with a natural gas or LPG fired boiler simply heating water, which is then circulated. It is a closed system, with radiators and natural convectors providing clean natural heat by radiation and natural convection. This technique eliminates dust and allergens being blown throughout your home.
