Scientific principals confirm that humans ‘feel warm’ if the air temperature around them is just 5 or 6 degrees Centigrade above blood heat. This can easily be achieved by turning the whole floor into a giant radiator with warm air gently rising naturally from the floor and cooling on its way to the ceiling. Typically with underfloor heating the floor air temperature is 22 ºC -   a metre up from the floor it’s 18 ºC and the ceiling is 16 ºC.

This runs counter to traditional radiator central heating which works on completely different principals. Heat from a radiator is thrown up to the ceiling where it collects before being forced down to the floor to heat the people in the room. Typically the floor air temperature away from the radiator is 14 ºC - a metre up from the floor it’s 18 ºC and the ceiling is 24 ºC. We’ve all experienced an overheated room where we have hot heads and cold feet.

Heating the floor instead of the ceiling seems such a simple and logical solution to heating that it begs the question as to why its taken so long to become popular in the UK.

Huge cost savings can also result from warm water underfloor heating - radiators require water to be heated up to 80 ºC whilst in underfloor it is between 30 ºC to 40 ºC  this huge difference in temperature results in savings of up to 30 % on heating bills.

It also means that several different types and combinations of heat sources can be used to produce warm water: solar, heat pumps, wood chip, biomass, electric, oil, coal and gas.
