Trench heating is where we install a hydronic convector system within a trench in the subfloor with a grill over the top that matches with your flooring.
It is the preferred method of heating a room with large expanses of glazing, little wall space or if panels are not desired. The pipes are laid from the boiler through the slab or subfloor to the end of the trench. The hot water heats a convector that is in one side of the trench so that as cold air falls off of the glazing into the trench it is then heated and rises.
The Trench box is built by your builder and should be a minimum of 230mm opening and 280mm deep at the length to suit heating the house. Most builders use any spare yellow tongue or similar and paint it black internally. At rough-in, the pipework is installed to service the trench(s) and will be the same pipework that services any radiator panels you may have.
