Water Underfloor Heating Running Costs

Water Underfloor Heating Running Costs

water UFH

 

 

Water Underfloor heating is usually more energy-efficient than warm water radiators or electric underfloor heating, so the running cost is lower.

 

This is because the heat emitted from an underfloor system is more evenly distributed than heat from a single radiator, so the system can use water at a lower temperature, It's usually between 27°C and 31°C

The running cost will also depend on a lot of other factors, including:

· How energy efficient your home is

· Room size

· Using time
