Boiler Installation

Boilers account for around 55% of what you spend in a year on energy bills, so an efficient boiler makes a big difference. Over four million homes in the UK are not connected to the mains gas supply and must use other fuels to power their central heating and hot water. A modern oil-fired central heating system can provide a cost-effective alternative and although oil produces more carbon dioxide than gas, a high efficiency boiler offers an environmentally acceptable option where gas is not available. The cost of fuel and energy is continuing to rise, so it is important to make our homes as energy-efficient and therefore as cost-effective as possible. With heating accounting for over half the average spend on energy in the typical UK household, a good heating system should be a priority. An effective central heating system in a well-insulated property will reduce heating bills and give the house a much warmer, more comfortable feel..

Oil Boiler efficiency

Since 1 April 2007 oil-fired boilers must have a Sedbuk efficiency of 86% or more (unless an exception is allowed). In practice, only condensing oil-fired boilers can meet this efficiency requirement. Typically, a new condensing oil-fired boiler will have an efficiency of 92% to 93%, compared with 85% for a new non-condensing Boiler and 60% to 70% for older Boiler Modern boilers are highly efficient and some manufacturers specify seasonal operating efficiencies reaching 97%, and there are a variety of ‘A’ rated boilers for oil systems on the marketplace. You can even check the efficiency of your boiler by checking the SEDBUK (Seasonal Efficiency of Domestic Boilers in the UK) database.

Oil central heating

An oil central heating system requires a storage tank on the property for the oil, which is burned in a condensing boiler or a combination boiler to heat water through a heat exchanger. The water is circulated round a network of pipes in the house, carrying heat to the radiators; just the same as a gas system. A good oil-fired system should have all the controls associated with gas central heating. The heat should be controlled by a single room thermostat, preferably in a living room rather than a hallway.

Practical alternative for central heating

Oil provides a very practical alternative for central heating for those homes, which are not connected to the mains gas supply. Most UK households, which have oil central heating, run the system on 28sec oil (kerosene). The oil is cleaner burning than 35sec oil (gasoil), and has the advantage that it can be used in kitchen range cookers such as AGA’s. Oil is not thought of as a clean or environmentally friendly fuel. If you are concerned about your carbon emissions, make sure you get the most efficient boiler possible, to reduce your carbon footprint as much as you can. DEFRA (the Department for the Environment, Farming and Rural affairs), estimates the carbon content for kerosene heating oil at 0.245KgCO2 per kWh, this is comparable to the figure for LPG of 0.214KgCO2 per kWh, and a carbon content in gas of 0.184 KgCO2per kWh. An ‘A’ rated, high efficiency boiler will help to minimise the difference in the amount of carbon you produce.

Installation costs

The installation of a full oil central heating system including the storage tank, boiler, radiators and controls is a large job, and one that is likely to cost several thousands of pounds. The Energy Saving Trust estimates that the cost would be around £3,500 – £4,500 for the installation of the system.


Once your installation is completed we will issue you guarantee for material, workmanship and installation, leaving you with peace of mind and a warmer home.
