Electric Boilers

In the UK it is common for most people to be connected to the main Gas grid. This in turn allows them to use the gas supply to power their central heating, ensuring their property is nice and warm and has ample access to hot water.

There are a massive range of different boilers available and the one you will need will likely depend on your properties current central heating setup and how much you are prepared to pay.

For example, you may need one of the following types of boilers:

  • Combi boilers:
    Provide both heat & hot warm by heating it from the main water supply and sending it to the various outlets in the property, such as your radiators and taps.

  • LPG boilers
    Popular for properties that aren’t situated on the mains gas grid, LPG boilers use an external LPG gas source that is hooked up to the boiler. The consumer can therefore shop around for the cheapest gas prices when they are close to running out of fuel.

  • Regular (conventional) boilers
    This kind of setup is common in older, larger properties. It consists of a conventional boiler that burns gas to produce heat energy. This heat energy is then passed through a heat exchanger which in turn transfers this heat onto the water, which is transferred directly to radiators for your central heating and stored in an external water tank for use when required. Cold water and feed & expansion cisterns and a water storage tank sit outside of the boiler, commonly located out of the way in loft spaces or airing cupboards, so regular boilers do require a lot more space. 
  • System boilers
    Pretty much work in the same way as a regular conventional boiler, but benefitting from having a lot of the required components built into them and removing the requirement for a feed and expansion cistern. This helps to make a system boiler a lot more space efficient.     

What happens if I’m not on the main gas grid?
Although most people in the UK have access to the central gas supply, this of course doesn’t apply to everyone.  
One option, as previously mentioned, is to have an LPG boiler, which will rely on an external gas source to fuel your boiler.


Another option is to join the increasing number of people who are choosing to rely on electric boilers. Despite being more expensive than gas as a fuel source, electric fuel boilers can actually provide a highly efficient level of performance and can actually contribute towards a financial saving on your heating bill outgoings. The reason for this is that electric boilers do not rely on the combustion of fuel within the boiler to generate heat energy (this occurs in power stations when the electricity is initially created), so almost all of the energy is utilised.

In a gas boiler a percentage of the heat energy generated is lost when waste gases are expelled from the property (despite massive improvements in condensing technology in recent years. Operating at efficiency levels of around the 99% mark, electric boilers do not need to worry about this as no such gases are created.

Electric boilers, like most other appliances, come in a variety of power outputs, with more powerful boilers more suitable for larger homes and vice versa. The Trianco Boiler range for example is one of the most popular electric boilers available on the market and boosts a range that stretches from 6kW to 12kW.

Electric boilers are nice and compact (as they don’t require additional components) and are easily installed. What’s more you don’t need to worry about arranging an annual service like you do with other gas boilers. Instead you just maintain your electric boiler system much like you would with any other electrical appliance, with the PCBs (printed control board) readily available to purchase should they ever need replacing.

If you aren’t on the mains gas grid, you could do a lot worse than considering an electric boiler for your home.
