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.
Household heating/cooling takes up some 35% - 45% of residential energy use, you can achieve plenty of saving on energy when adopting a 'dual fuel' hybrid system; using heat pump for less punishing weather and stick with a gas furnace for really cold months. It is a proven technology and you can now alternate very warm air with very hot air through heat pump and furnace respectively.
Energy used for `residential heating has been on the rise lately. According to a 2005 survey, the average American household burned somewhere around $1200-$1500 for heating alone. It makes sense that we look into ways to bring down this amount. One of the necessary measures is to give your furnace a proper tune up in order to make it run more efficiently.
Residential heating systems are made up of three components:
Annual Fuel Utilization Efficiency, or it AFUE for short, gives an indication (measures in percentage) of how much fuel is successfully turned into heat in relation to the resultant exhaust gas. It is not uncommon to find high-efficiency gas furnaces which offer AFUE reading of 90 to 95%. What this means is that as much as 90 to 95% of the fuel is used to produce heat, while the balance of 5 to 10% is being wasted as exhaust gas.
