You can use warmth trapped within the earth's crust to heat your house. Installers bury pipes underground, then fill those pipes with water. The water absorbs the earth's heat, warms up and can then be pumped - as warm air - into your house.
The QuickBOLT is THE affordable mounting solution for Asphalt Shingle Roofs. Not only is it the lowest cost system in the industry, it also maintains the fastest install time of any mounting system available. Unlike other Asphalt Mounting systems that require bulky flashing, the QuickBOLT uses a small EPDM washer and is 100% waterproof!
