Retro-fit options like Rapid Response® floor heating boards are laid directly under your floor finish and when covered with the optimum thickness of 200 micron aluminium they provide Rapid Response® warmth reaching desired temperatures in 30 minutes and ensuring an even heat across the entire floor – this makes floor heating just as controllable as radiators.
Old fashioned floor heating laid deep in concrete could take up to 72 hours to heat up or cool down.
