B6 - WATERLOO CHRONICLE, WEDNESDAY. OCTOBER 23, 1985 rafty doorways affecting the comfort of D your home? Doors that are not well sealed and insulated will allow a lot of cold air into your house and have a noticeable effect on your heating bill. In any doorway, properly installed weather-stripping will make a big difference. You should look for a product that is strong,' secure and resilient. It should also be easy to replace, since it will be under a lot of stress from opening and closing the door. . "WEEK olosihg iiiiiuddr, you should have to pull it to get it latched. This indicates a pressure seal that will stop air leakage. - _ _ - . Where possible, the tops and sides of any door frame should be weather-stripped so that it makes contact with the edge of the door to provide a good seal even if the door should warp. The V-shaped compressible metal or vinyl weatherstripping is best. . Weatherstripping against the face of the door should be checked often, because it will have to be adjusted occasionally to match the warping of the door. It is very important to weatherstrip the threshold of the door because this is frequently the location of serious drafts. This can be achieved with weatherstripping attached to the threshold or to the bottom of the door. "If "tiiGvdatiferstripping is attached directly to the top of the doorsill, it must be very durable to withstand heavy use. Remember to check for Close door on wasted heat ith uncertain oil prices, the patterns of energy use in Canada are changing. and one element of this is a move back to biomass fuels - those which are derived from plant matter and are renewable, such as peat moss, animal manure and logging residues. The Queen Elizabeth Hospital and the Hillsborough Hospital near Charlottetown, Prince Edward Island, for example, have more than their location in common - they are both partly heated with garbage. The energy-from-waste (EFW) facility, located in the town of Parkdale, converts refuse generated by the surrounding population into steam for the two hospitals. By using municipal waste as an energy source they are saving more than 2 million litres of imported oil each year. This is the last Autumn in which Canadian Home Insulation Programme (C.H.l.P.) grants will be available. Residences built before Sept. I, 1977 are eligible for grants of up to $500.00. Where the grant has been partly used, the balance can be applied for. For registration and In “not. call The forest industry has been the pioneer in this transition to biomass. Pulp and paper mills and sawmills have been converting much of their wood waste into useful forms of energy like heat and electricity. Hospitals, food processing industries and other large-scale energy users are now following the lead. Charlottetown had a growing problem with waste disposal because it is surrounded by fertile agricultural land. Landfill sites were difficult to find, so the refuse had to be trucked far from the city. The establishment of an energy-from-waste plant assisted in solving this problem as well as providing energy from a local. renewable energy soqrce. HOME INSULATION GRANTS -..“W ___-Pee'-. The facility was designed and assembled on site. It consists of three modular-type combustion units that are highly efficient. each capable of handling 33 tonnes of garbage a day. A heat exchanger extracts the heat from the combustion gases and generates steam. which is sent by pipeline. at a high pressure, to the hospitals. The cost of the facility was approximately $9.5 million. of which Energy. Mines and Resources Canada provided $4 million - . . _. . - A ----_ I.___t:‘_ "s.. IAIICIK].

Any number of other materidis will provide an effective seal, but the key is to check it regularly because there is so much movement within the house structure, as well as from the movement of the door. If your door has glass in it, you should take the same precautions as you would with any other window. Double glazing should be used with adequate caulking around the edges. Since patio doors are usually used only as windows in the winter, they should be thoroughly sealed with weatherstripping or duct tape. North-facing patio doors are probably the best place to start if you are considering insulated blinds or shutters. Vestibules form an airlock that can significantly reduce energy loss through doorways. A closed porch, garage or specially constructed entranceway can lower heat loss when doors are opened. If your home does not already have one, you should consider constructing a vestibule entranceway when home renovations are planned. Storm doors provide an extra layer of insulation from the cold and can be a valuable energy conservation measure. They are fairly inexpensive and their installation is not complicated. Ask about the new brought to you by the remarkable heat pump If you're looking for a more efficient heating system that also gives you central air conditioning, look at the remarkable heat pump. The heat pump provides warm, even heat in winter, and with a flip of a switch, cools and dehumidifies your home in summer You can select a model that can be added on to your existing furnace, or replace your old heating system with an all-electric heat pump. A heat pump in your home could save you up to one-third of what you're now paying to heat with an oil or gas-fired system, Remember, a heat pump gives you year-round comfort and maximum energy efficiency 77’5ka " LOANPLAN l-I-l -- -- “I ';"-Fr), TLC' j/il/til m on I. -l llTPrlf 'rr/r, I II-I-I a“; -..'I-.!I I _- TPrllz:l:j I Several colors Barth known -- and natural and natural o ore, ox' 1‘ D.
