AQUATHERMAT® with condensation boiler

The high efficiency level, small size, ease of installation and moderate cost of the condensing boiler make it one of the best solution available as a heat source for AQUATHERMAT®.

  • A temperature sensor inserted in the substrate is used by the control system to calculate the supply temperature required to keep the soil at the proper set point.
  • The installation of a mixing valve is not required because it is possible to modulate the boiler temperature from as low as 85°F.

  • Their stainless steel construction also eliminates the need of a heat exchanger.

  • An expansion tank and a pressure regulator (12 PSI) must be installed in order to protect the mat's hot water conducts.

  • The circulation pump must be activated at all times in order to keep an even temperature across the mats.

  • The by-pass valve is used to adjust the circuit pressure.

  • The purge and shut-off valves are most useful to bleed the air out of the system at start-up.
