What are "combined" and "separate" radiant heating systems? A combined hydronic radiant heating system used the same tank to heat both the water for showers and sinks and the water that is circulated in a closed loop to heat your home or office. A separate radiant heating system has one tank or boiler for the space heating and another for the domestic hot water.
What is a radiant barrier? A radiant barrier is a layer of metallic foil that blocks radiated
heat, assisting in the energy performance of a home. It significantly
reduces attic temperatures in the summer. If your cooling ducts are in
the attic you will see an improvement in the cooling of your home.
