Combination Space and Water Heating

The GFX can be combined with tankless water heaters to not only recover heat from drain water, but to heat the whole house. The following diagram shows how such a system can be configured.

Advantages include:

  • Minimal standby losses from stored hot water.
  • Two consecutive showers pose no problem with the GFX heat recovery unit.
  • Very low operating costs.
