You can use taditional radiators but these arent considered very efficient.
Underfloor Heating (UFH) has been around since Roman times in one form or another and now its been perfected to make best use of all that geothermal energy under your back garden.
There are limitations to where underfloor heating can be installed, new builds and restortions offer the best scenario for this kind of heating, dont worry if you dont fall into either catagory well decuss all options with you.
Each underfloor system will be designed to specifically suite each situation. Different areas of a building requires a different approached to laying the underfloor heating tubes, some areas will require more heat, other areas a lot less, again this will be discussed fully with you.
Once youve experienced underfloor heating you wont want anything else.
