Previously, water-based underfloor heating was often not looked upon as an alternative when building outdoor rooms because of the risk that the underfloor heating pipes would be damaged by freezing. One alternative has been to allow the heat to be on all year, even during the coldest months when the outdoor room is not in use, or to install electric underfloor heating. There is now a simple pre-assembled solution that offers you an opportunity to use the house's water heating system. Using LK Underfloor Heating you can enjoy your outdoor room from early in the spring to late into the autumn. The solution is the LK Heat Exchanger Pack, which separates the underfloor heating from the heating system used in the rest of the house. The underfloor heating system can then use frost protection with glycol and in this way you can safely shut down the system without risking damage from freezing.
