Did you know heating equipment takes about 15¢ from every dollar of energy cost to operate itself? The house takes the remaining 85¢.
SEALING YOUR HOME’S ENVELOPE
Your heating equipment is only part of the equation. The efficiency of the envelope (the outer walls, floor, ceiling or roof) also calls for thought. A heating system provides heat and the house uses (or wastes) it, in exact balance.
AIR LEAKS VS. INSULATION
Most homeowners assume insulation is the answer. However, insulation is not the whole story. Air leakage is the biggest robber of heating dollars.
Houses leak air because of the difference between indoor and outdoor air pressure. Think of a hot air balloon. The biggest pressure differences are high and low in a building. Holes in these areas leak more air than holes in the middle. Warm air rises and leaks out any unsealed areas at the top of the building. Leaks inward tend to be at the bottom of the structure, pulling in cool air.
"Airtight" homes are economical and more comfortable, if proper ventilation is provided. No drafts, just controlled air flow. Home that leak have moist, heated air escaping into cooler areas, such as insulated walls and ceilings. This vapor condenses, causing mold, mildew, rot and other moisture-related problems. This is a major health concern as it is a primary source of allergy symptoms.
