Is Oil Fired Central Heating energy efficient ? This is a question asked by many many of our users especially as winter approaches. The answer is yes. A good quality oil fired central heating system, well installed, should give you every bit as much efficiency as a gas system. For the best oil fired heating system the same control should be offered as those given in any similar system.
- Room Thermostats should be used, especially in the lounge.
- The thermostats and boiler should be wired in an interlock to stop any short cycling when either hot water or room heating are not needed.
- The hot water tank should have a cylinder thermostat
- Hot water and heating should be programmed seperately on a 7 day timer
- Thermostatic Radiator valves should be placed on appropriate radiators.
Oil Fired Boilers
An oil fired boiler, especially a condensing model, can give an efficiency rating of up to 98% just as gas can. From April 2007 it must be noted that boiler installations must be made with a condensing boiler. Oil fired combination boilers are also available but it should be noticed that the hot water on demand feature of a combination boiler is a little slower in the oil boiler field. Oil boilers can be fitted with balanced flues or with open flues but we would suggest that a balanced flue boiler is much more versatile, efficient and can be used in more siting locations.
Oil Used in Central Heating
Just about all oil fired central heating used in Britain on a domestic level uses 28sec oil. This oil is sometimes referred to as Kerosene. 28sec oil burns very cleanly leaving minimal deposits on afterburn. 28sec oil can also be used in popular kitchen ranges like AGA. The CO2 emissions for oil fired heating are, using an efficient boiler, no greater than normal gas.
Fitting an Oil Fired Central Heating Boiler
Fitting of Oil Fired Central Heating boilers should be done by a competent fitter. That is a fitter who is capable of measuring flow and pressure before the boiler is commissioned and again afterwards to make sure there are no leaks or dangers to the home owner. It is not recommended by DIY Doctor or Oftec ( http://www.oftec.org.uk/ )that any form of central heating boiler is installed in a DIY Fashion.
Central Heating Oil Tanks
Oil tanks are sited outside the house and should be seperated from the boiler by an automatic shut off valve which will prevent any fire in the boiler spreading to the tank. Modern oil tanks are made of plastic and are relatively easy to keep clean and maintain. Rules and regulations concerning the siting and care of combustion appliances and fuel storage systems can be found in Approved Document J of the building regulations. Information regarding Chimney stacks, flues and hearths can also be found in this document. The rules governing how far an oil tank should be away from the building depends on a few things including whether part of the building will overhang the tank in any way or at any height. Slim line tanks could solve the problem if space is an issue.
Providing, of course, that the walls to your house offer a minimum fire resistance rating a tank can be sited a lot closer to a house than one would think. See our project on building regulations to find out more.
