Slab Insulation and Radiant Heating

Before the basement concrete slab was poured, a 2″ thick EPS (R7) was put in place to reduce the heat transfer to the soil beneath.  In addition, PEX tubing was run in 90% of the basement floor space to allow for in-floor radiant heating.  In-floor radiant heating allows for a more comfortable basement floor as it is no longer cold to walk on, and is efficient as heat rises throughout the house in the winter, as well as a reduction in the heating area that the fan coil has to service.  The garage was insulated and roughed-in with the same system for the ability in the future of a heated garage.

The tubes are connected to the Daikin Altherma system, which provides radiant heating to the basement floor as well as the fan coil to heat the ground and second floors, as well as heating the hot water for the house.
