Underfloor heating has been in use since Roman Times and, with refinements, still provides steady comfortable heat for the modern home.
How it Works
Approved plastic pipe (PEX) is embedded in the concrete of a new home slab covering all or some areas of the home. Pipes are laid throughout the floor in a series of Loops of approx 100m per loop maximum. Water at a temperature of approx 45C-50C is pumped from the heat source and through a mixing valve, which regulates the temperature, around the pipe and therefore heating the floor.
The heat source can be a Wood Fired Boiler, Gas Fired boiler or even a Heat Pump System
Water temperatures can be kept low as the entire floor is heated evenly and as the room is heated from the bottom up leaving no areas of cold and producing no noise or draughts. Compared to wall hung radiators, underfloor heating takes longer to heat up , as the entire slab has to heated , however it also takes a longer time to cool down. This means that there is less of a temperature drop in the case of the wood boiler , or gas boiler being turned off or going out. If the wood fire goes out overnight the floor temperature will not drop as fast as a wall hung radiator.
floor heating is unobtrusive with the distribution manifold being housed in a plant room or cupboard the underfloor part of the system is invisible.
Installation should be carried out by a qualified and experienced tradesman. The pipe is laid in the floor prior to the concrete being poured with the manifold etc being installed during the plumbing stage of the build.
