Saskatchewan's Green Directory Helping Saskatchewan choose a better environment

Underfloor water pipes are generally an environmentally preferable option to conventional air-blown systems for a number of reasons. They enable more consistent heat distribution, with no serious hot or cold spots. By operating at a low temperature they enable condensing boilers to run at maximum efficiency for much of the time. They can make a solar contribution to space heating viable in a well-designed system. Perhaps most significantly, in the absence of continuous forced air flow, residents/occupants feel comfortable at lower indoor temperatures, enabling the thermostat to be turned down.

What to look for

• The installer should use PEX or Kitec piping, for reliability in avoidance of leaks.

• The system should be designed and installed by a competent specialist who can provide evidence of a good track record.
