See the Central Heating Design article for pros and cons of underfloor heating compared to radiators etc.
The use of warmed floors to heat spaces goes back at least to the Romans who used hypocausts to heat buildings using wood as fuel. Modern Underfloor Heating systems ("UFH") can be designed and installed as part of a wet hydronic Central Heating system or can be separate Electrically heated areas.
The following regards wet CH-based systems:
Suppliers
Uponor
Uponor (formerly Wirsbo) are long-established suppliers of UFH.
Their web site's pages carry the now-common indication of the path through the document tree to the current page e.g.
but you can't always get further along the path from a given page! Instead you have to use the pop-up menus from the navigation bar on the left of the page. |

Royalle
Supply a range of typical UFH systems but also make a thin (15mm or 25mm finished) screeded system based on zinc-plated steel honeycomb which, it is claimed, can be laid over existing wooden floors, even those in poor condition. The system is also claimed to have relatively short warm-up and cool-down times.
