How long does it take a Warmup heating system to heat up?

Remember: Heat up times are up to 3 times faster when Floor Heating is combined with proper floor insulation. Heat up times will vary depending on the construction of the sub floor. For example, uninsulated concrete subfloors will take considerably longer than plywood sub floors. Heat-up times will depend on such variables as the thickness of the tiles and the design of the sub-floor however, here are some rough guidelines:
  • Concrete with 10 mm tile-backer insulation board : 1 hour
  • Un-insulated concrete slab: 2 - 8 hours
  • Insulated concrete slab - insulation under screed: 2 - 5 hours
