A new boiler installation cuts energy bills1

Replacing an old or inefficient boiler or heating system can mean big savings on household bills. A new boiler will help you stay warmer at home too, and give you hot water you can rely on at the turn of a tap.

How efficient is your boiler?

We forget how much we depend on a boiler. It’s only when it breaks down that we realise just how much we need it every day. From a hot morning shower and doing the dishes, to welcoming warmth on a cold night, the boiler is the heart of life at home.

Ask us for a no-obligation home energy assessment and we can assess your boiler and heating system and its controls. If it looks like your boiler needs maintenance, or it’s time to be replaced, we can let you know.

The best boiler for your home

We make sure we understand the lifestyle and needs of your household before recommending the best boiler for your home. For example, if you have a loft conversion, or you live in a flat or bungalow, a Combi or System boiler may be right for you. If you live in a larger property with more than two bathrooms, a Regular, System or floor-standing Combi boiler may be a good choice.
Low mains water pressure is also taken into account, as is the age of your property and its existing central heating system.

The extra efficiency of ‘condensing’ boilers

We install the most efficient condensing boilers from leading manufacturers, known for their quality and heating technology.
A condensing boiler not only creates heat when it burns gas or oil, it also creates condensation. This helps to recover more of the heat left from cooling flue gases, further improving fuel efficiency. In effect, 90% of the fuel a condensing boiler uses is turned into heat. That means at least 90p in every £1 you spend on fuel goes towards keeping your life comfortable at home.

Savings and cost

The cost of installing a new boiler will depend on your property’s size, age and current heating system.

If you need to upgrade your boiler we can help you find the best value option. We’ll talk you through the recommendations and give you a fixed price quotation, so you know exactly what you’ll pay if you decide to go ahead. We can also check to see if you qualify for any grants or funding to help pay towards your boiler replacement.

Boilers – a quick guide

Combi or Combination Boiler

  • A good choice when living space is at a premium: heats water directly from the mains when you turn on a tap, so there’s no need for a separate hot water storage cylinder or a cold water storage tank in the roof space.
  • Acts as a high efficiency water heater and a central heating boiler in one single compact unit.
  • Hot water always available on tap, no waiting for it to heat up.
  • Very cost-effective and energy efficient as water is heated instantly, rather than being heated and stored in a cylinder.
  • Hot water is delivered at mains pressure; can provide a powerful shower without the need for a separate pump.
  • Less pipework needed means installation is usually more cost-effective.

Regular Boiler

  • Ideal for a home where lots of hot water is used at the same time, and where there are two or more bathrooms. Also sometimes called a traditional, conventional or heat-only boiler.
  • Heats the central heating system directly, with the hot water stored separately in a hot water cylinder.
  • Needs a cold water storage tank in the loft to feed into the system.
  • Regular boilers are compatible with solar water heating systems.
  • Can be the best boiler replacement for a property that has an older radiator system, as it does not operate with the higher water pressure of a System or Combi boiler.

System Boiler

  • Works like a Regular Boiler, storing hot water, but many of the workings of the heating and hot water system are already built in to a System Boiler, making installation faster and easier.
  • No need for a tank in the loft, so suitable for homes where there is little roof space or the loft is converted.
  • Economical to run and is also compatible with solar water heating systems.
