Floor Heating Heat Sources


Heat Source < 120° F

The heat source choice depends on availability and regional cost. The system is readily adaptable to a dual source heat supply.

When the construction is Ground Slab Construction (Basements), Suspended Concrete Flooring or Tile Flooring, the temperature for “in concrete" tubing is typically less than 120 deg. F. This low temperature makes this heating system suitable for any heat source.
Geo Thermal Heat Pumps and Solar Panels are readily adaptable.
 

 

Solar Heat Sources - Efficiency may be infinity

Heat can be drawn directly from the solar panels or can be drawn from a solar storage system.


Through good design and the use of concrete within the dwelling, solar storage
can be accomplished in the floor very effectively. The accumulated energy (heat) can provide comfortable temperatures throughout the night.


Solar systems should have a series of limiting thermostats, both high and low temperature, to avoid over heating or cooling depending on water temperature.
We recommend that you work with your local solar expert.

 

 

Heat Pump - Up to 300% Efficient

When using a heat pump, it is desirable to remove all heat produced. Removing the maximum amount of heat will increase the efficiency of the heat pump and consequently, the heating system. Always using a heat pump with a single zone system is recommended.
 

 

Heat Source < 160° F

When Q-Panels are used a higher temperature is needed. Typically up to 160 deg. F from Natural Gas, LP Gas or Electric (night current).

 

Natural Gas or LP Gas - Features should include the following description:

  • Heat source should be a condensing design to operate at low temperature and at a maximum efficiency

  • Sealed combustion air intake and exhaust should be piped for max. efficiency to avoid oxygen consumed from inside the dwelling.

  • See the WarmmFloors Product Catalog.
