In recent years, we've switched hundreds of customers from fossil-fuel heating to electric. This number does not include hundreds of other conversions by other, independant electrical contractors. So what exactly is so appealing about electric heating?
Easy to fit and install
Most boilers can be easily replaced with an electric equivalent without too much disruption. Your oil storage tank can be removed too.
Will they work with existing radiators or underfloor systems?
Yes - we can replace an oil or gas wet radiator system or existing wet underfloor heating system with electric. The existing pipework and hardware can be kept, all the way down to the controllers - though you may wish to upgrade to a new 'smart' controller - so it's often a case of taking your old boiler out and simply fitting a new one in its place.
Some homes may require a separate water heater installed. This can be in place of an existing immersion heater, but if there isn't already a cylinder in use, our advisers can find the best place to install one with minimal impact. For completely new systems, we can advise on both radiator-based, underfloor or a combination of both to ensure you get the very best from your electric boiler.
Economical and 100% efficient
An electric heater is regarded as 100% efficient because its energy input – the electricity you are billed for – matches its heat output and nothing is lost in-between. In comparison, an old oil or gas boiler could be only 65% efficient, meaning you are only getting 65p of heat for every £1 on your bill. Unlike a fossil-fuel powered system which gradually loses efficiency with age, electric boilers will remain 100% efficient throughout their lifetime.
Electric heat also comes with less expensive equipment and lower installation costs.
Electric heating produces no toxic waste such as Carbon Monoxide. But why does this matter?
Burning fossil-fuels in air creates a number of harmful by-products. Oil and gas heating systems require an open flue which takes air from inside the room and uses it in the combustion process.
When any carbon-based fuel (such as mains gas, LPG, oil, solid fuel, wood, or charcoal) is burned, it uses oxygen as part of the combustion process. With a good supply of fresh air, this will produce fumes including Carbon Dioxide, which is safe in small amounts. However, global warming is caused primarily from putting too much carbon into the atmosphere.
If there is not a good supply of fresh air, the combustion process will produce fumes including Carbon Monoxide (CO), a toxic poison. If this is produced in a poorly ventilated area, the level of CO will build up in the air. When inhaled, CO absored in the blood becomes more concentrated and replaces oxygen, suffocating and poisoning cells in the muscles and vital organs.
All appliances reliant on fossil-fuels should be checked and serviced regularly by a qualified engineer. Rooms should have sufficient ventilation and include an audible carbon monoxide alarm.
Compact and quiet
As no flame exists, electric heating systems are significantly quieter than oil or gas heating systems. You can also get rid of cumbersome oil tanks, ugly gas bottles, unsightly flues and free up precious space in your garden or outdoor area.
Lower Running Costs
A 10-year gas boiler lease plan may sound tempting, but it could cost you more in the long run. In an average two-bedroom home a new gas boiler, which might be 85% efficient, could cost approximately £1,208 per year to run. In comparison, an electric boiler will cost just £695 per year to run in a similar home, based on the heating system using 7,500 units of electricity.
Initial installation costs for an electric heating system are often more than the cost of simply replacing an existing gas boiler with a new gas boiler. This is due to modifications required to the existing system pipework, the installation of additional electrical circuits and the fitting of a separate distribution board to connect to the superheat meter.
However, in most cases over the lifetime of the boiler, the combined installation and running costs of an electric heating system will normally work out better value for money than a gas heating system. If you let us have 12 months of gas bills we can work out exactly how much you would save as part of the service we offer.
Black mould caused as a result of moisture can be detrimental to health and the quality of your home. Condensation dampness can occur in rooms where lots of moisture is produce and on cold surfaces. Condensation can be avoided by reducing the amount of moisture produced at home, creating adequate ventillation, and increasing heating when required to raise the temperature of the air and warm cold surfaces.
Adequate heating is important for combating condensation problems as it warms up the air (allowing it to hold more moisture) and internal surfaces. Unheated bedrooms can often suffer from damp as cold walls and windows attract condensation. Bottled gas heaters in particular are not advised in homes which suffer from condensation problems as for every litre of fuel burned, the heaters will release an equal quantity of water vapour.
Electric heating helps reduce your carbon footprint as it emits no harmful emissions. Because the majority of Guernsey’s electricity can come from sustainable, lower-carbon sources, when you switch to electric heating you’ll already be doing your bit for the island to be greener.
Over 85% of our electricity is imported from guaranteed lower-carbon sources in France via our undersea cable, GJ1. Our energy mix is made up of 33% certified hydropower, 53% lower-carbon nuclear leaving only 14% generated on-island at the power station.*
Electric heating can also help reduce the number of vehicles on our roads as there's no need for fuel delivery lorries. With no domestic oil tanks or gas cylinders, it can also help reduce the risk of pollution from leaks and spillages.
Our Solar Panel array at the power station generates electricity for the benefit of the whole community. In its first 50 days, the solar panels generated enough energy to light and power seven homes for a whole year, or drive 100,000 miles in an electric vehicle (EV).

Safe and easy to use
As well as being simple and user-friendly, electric heating has no flammable fuels, no flames and no emissions, so there’s no carbon monoxide to worry about. Electric heating presents no potential safety hazards where flammable vapours may be present, such as garages, basements and storage rooms.
For added peace of mind, Guernsey Electricity offer heating maintenance packages to suit your budget. Every system, no matter how reliable. should be serviced regularly to ensure everything is functioning correctly.
If you're currently on an oil-powered heating system, make sure your maintaining your oil tank. Watch this video for more information.
It is recommended that all Gas appliances are serviced at least once a year to ensure safety and reliability. For Landlords, it is a legal requirement under the Health and Safety (Gas) (Guernsey) Ordinance to have a gas safety inspection and safety certificate every twelve months
Integrated with renewable technologies
A boiler or immersion heater can be used as a backup or to supplement heat stored from renewable energy, such as solar power.
Installing a new electric boiler is often fairly straight forward, requiring modifications to the existing system pipework, the installation of additional electrical circuits and the fitting of a separate distribution board to connect to the superheat meter.
However if your electric supply needs upgrading in order to meet the demands of the new heating system, a service upgrade would be required. But don’t panic, this doesn’t necessarily involve digging up your house floors. If required, we would carry out a survey for the service upgrade and discuss with you the best options to upgrade the service, with the least amount of disruption whilst ensuring any cables are hidden, or discreetly positioned.
If you think electric heating could be for you, arrange your FREE home visit.
Let us know your current heating costs and we’ll work out how much a new electric system would compare to your existing heating over a 10 year average. We’ll then provide a quotation for a new, modern heating system that best suits your home.
If you accept the quotation, we will schedule the work, install and test your new system, ensuring its operating on the correct tariff. Or, speak to your preferred plumber or electrician to arrange an installation.
