To work effectively, under floor requires water temperatures of between 45oC and 55oC. These temperatures are easily obtained by blending flow water and return water from the under floor system by means of a thermostatic mixing facility supplied.
No, advances in material technology make it possible to have a cost-effective heating system that incorporates energy efficiency and high performance, utilizing low water temperatures of between 45oC and 55oC. Typically, radiator systems operate on higher temperatures, thus making them less cost effective in the longer term.
Every system is custom made to individual project requirements including bespoke design. It is important to design every under floor heating system individually so that the exact heat requirements of the room can be met. The danger with kits is that the heat requirement is calculated incorrectly leaving the room with inadequate heat.
On screened floors the approximate output is 100W/m2 in living areas and up to 130W/m2 in hall areas. On plated and floating floor applications the approximate output is 70W/m2
