Fireplace Efficiency The best way to determine the efficiency of a gas fireplace is to look on the EnerGuide label for its Fireplace Efficiency (FE) Rating based on the CSA-P.4 test method. What are HIGH EFFICIENCY Gas Fires? WHAT WE ARE DOING TO PROTECT YOU? What are the different gas fire styles? Sit back and enjoy the fire, without worrying about how much it might cost you. The lowest efficiency allowed by law for new gas furnaces is … NA. Another factor is the efficiency of the heater. Typically the difference between the value of the net combustion efficiency and the value of the gross combustion efficiency for a natural gas fire is around 5 to 8 percentage points with the net value being higher than the gross value. Gas fireplaces cost 17-19 cents an hour to run, or about $60 annually, Electric Fireplaces Direct says. That means almost every one of the methane molecules combines with two molecules of oxygen, producing one molecule of carbon dioxide, two molecules of water vapor, and some heat. Gas fires are seen as more efficient to run than their electric counterparts, and they also give out more heat. However, for a gas fireplace the actual amount of heat can be measured because it delivers heat directly into your home. Annual Fuel Utilization Efficiency (AFUE) is typically used with appliances that continually cycle on and off to maintain a constant temperature, such as a furnace. Gas fireplaces use between 7,000 and 16,000 BTUs, are between 70 and 90% efficient at converting energy to heat, and cost around $60 a year to run. Use this checklist to help find the right fireplace for your home. Glass fireplace doors raise the efficiency somewhat but only to about 20 percent. Gas – approx 5p per kw; Wood – dependant on source, approx 10p per kw; BioEthanol – approx 90p per kw; Fireplace Efficiency Rating. Gas Heat: Steady-State vs. AFUE/EnerGuide. The running costs of a gas fire can be calculated quite simply using the following calculation: Running Cost = Energy Input (gross) x Your Gas Bill Tariff.Example for a Blenheim High Efficiency Gas Fire: Energy Input (gross) 5.0kW x Gas Bill Tariff (gross) 4.00p/kWh = Running Cost 20.0p per hour. In practice, efficiency varies depending on the style of the appliance. This FE number may be found in a number of different locations including the … Some of the heat gets lost in the ductwork as it travels throughout the house. You should always make sure your appliances are energy efficient models and are running properly to avoid wasting fuel. The Steady State efficiency rating, which offers a higher and more impressive number, is taken only once, after the appliance is fully heated up and burning steadily. READ ABOUT FIREPLACE TYPES Some home upgrades will pay you back, and some won’t. Two-pipe vented gas fireplaces that draw fresh air from outdoors … In simple terms, it is a measure of how much of the heat generated goes into heating the room compared to how much is wasted (e.g. Insert. Gas appliances have a BTU consumption rating that indicates the amount of gas they use in an hour. Gas fireplaces come in three types: inserts, for folks who want to retrofit a wood-burning firebox with something more convenient and efficient; built-ins, for those who want a fireplace where there isn't one now; and log sets, basic burners that sit in existing, open fireplaces. The second type – a heat producing type – is a gas insert or gas fireplace. Different methods have been used to measure the efficiency of gas fireplaces. 1895 S.
