Retrofitting underfloor heating into an older property is certainly possible. If your home features suspended timber floors, there are several available water underfloor heating systems available on the market which can be installed within the voids beneath original timber floorboards. This can be a complicated project, typically involving installing the system ‘from above’ or ‘from below’- from above meaning taking up the floorboards and from below meaning removing the ceiling in the floor below the room in which the floor heater is to be installed.
Electric systems can be easily installed into older properties, simply use the original floorboards as a subfloor onto which the system is installed and cover with a new floor finish of your choice. Timber also makes fantastic subfloor for underfloor heating as it is a naturally conductive material which distributes heat effectively.
