Hydronic radiant floors
Are you aware that as much as 35% to 45% of residential energy bills go to heating/cooling? Radiant floor designs can save 40% of your heating costs while keeping the house comfortable. It also comes with 'no-noise' guarantee since heat is transmitted over the floor (it does not make use of mechanical parts like fans or blowers). It can go under the existing floor between the joists or under most finish materials.
