The cost of purchasing and installing a new furnace is often expensive for the average homeowner. In addition to purchase costs, homeowners must consider operational costs during times when the winter weather outside turns home heating equipment into an essential tool. Home heating is an essential comfort, but it can also be an expensive one. In order to help consolidate their expenditure, London, Ontario homeowners must have a contractor correctly size their furnace before installation. Within this article, we’ll focus on the importance of the size of the furnace when reviewing the great range of product options currently available on the market.In the past, homeowners regularly installed furnaces that were too large for their property. This meant that peak energy usage efficiency was rarely achieved within the property. But with energy costs comparatively low in previous decades, few homeowners spent time worrying about the extra few cents they were paying due to their inefficient furnace systems. These days, energy prices have risen to levels that have left millions of Canadians paying high energy bills each month. And now homeowners across the country are looking to heating specialists for help in implementing cost-effective, high efficiency solutions within their property. Heating efficiency is an important element involved in selecting the requisite furnace product. When optimal efficiency is achieved, homeowners can reduce their overall expenditure significantly and ensure they have the financial flexibility to cover all home ownership costs. So the question is: how can homeowners determine the ideal size of product for full heating efficiency within their property? The first step in determining the size of furnace required involves conducting a heat loss calculation. In order to be completely accurate, the heat loss calculation must be carried out by a qualified local-area heating contractor. To determine the level of heat loss within the property, the London, Ontario furnace specialist will take into consideration various environmental parameters. These include: the house age, the area of heated space, the efficiency and size of windows, as well as the insulation depth in the attic, walls and basement. By completing this heat loss analysis, heating contractors will then be able to determine how much energy, measured in BTUs (British Thermal Units), is required to adequately heat a property during periods in which the weather outside is extremely cold. Gas furnaces will have both a BTU input number and an output number. The smaller the difference between the input number and the output number, the higher the level of efficiency offered by the product. Once this number is achieved, the heating contractor will then be able to determine the size and style of furnace required for the property. That’s because all furnace manufacturers provide a BTU sizing for each product they build and furnace size across the market is measured in increments of 10,000BTUs. Not all heating contractors will be able to conduct a heat loss analysis. So it’s imperative for homeowners to ensure that the London, Ontario furnace experts they select can carry out this task with professionalism and accuracy. By selecting the right organization for the job, homeowners can ensure they save thousands of dollars over years of high-efficiency furnace use. For more information visit:http://www.myfireplace.ca/ .
