Combi Boiler

All of our boilers are high efficiency boilers made with the highest quality components for efficient working. High efficiency domestic boilers combines the finest German engineering and British manufacturing, to give you a outstanding performance and long lasting reliability from your heating system. With a broad range of combination, system and open vent boilers available in outputs to suit all types of properties/ house types.

What is a combination boiler?

This popular type of boiler heats hot water.There is no need to install a hot water cylinder or cold-water tank, as the boiler is connected directly to the water mains ‐perfect for homes with limited space and a smaller hot water requirement.


  • Gas Combi boiler contains almost all components within the boiler itself,
    which makes the boiler system more compact and neater looking.
  • There's no need for a cold water or feed and expansion tank in the loft and you can immediately get hot water heated on demand.

What is a system boiler?

This type of boiler works together with a hot water cylinder, but usually doesn’t require a cold-water tank, as the system can be filled directly from the water mains. This type of system benefits from having an electric immersion heater within the cylinder that means you can still have hot water even if your boiler breaks down.

What is an open vent boiler?

This type of system is more traditional and is found in older houses. They work alongside a separate hot water cylinder (often found in the airing cupboard) and use a cold-water tank (often found in the loft). Like a sealed system, this type of system is normally suited to a larger home with a higher hot water requirement.

Installing the right boiler

Most old gas and oil boilers are regular boilers. They have a separate hot water cylinder to store hot water, rather than providing it directly from the boiler. When you replace your boiler you have a choice of buying a new regular boiler, and keeping your hot water cylinder, or buying a combi boiler that doesn't need a cylinder. A regular boiler is more efficient than a combi at producing hot water in the first place, but then some heat is lost from the hot water cylinder, so a combi may be the most efficient and these days most commonly used boiler.

The best option for you will depend on a number of factors:

Boilers account for about 55 per cent of what you spend in a year on energy bills, so an efficient boiler makes a big difference.

Replacing an old gas boiler with no controls, with an A-rated high efficiency condensing boiler and full set of heating controls will significantly cut your home's carbon dioxide emissions, and could save you as much as £305 a year.

Why are new boilers more efficient?

Modern boilers are more efficient for several reasons, but their main advantage is that they are all condensing boilers. All well-maintained boilers burn their fuel very efficiently, but they inevitably lose some heat in the hot gases that escape up the flue. A condensing boiler has a bigger heat ex changer, so it recovers more heat, sends cooler gases up the flue and is more efficient. Sometimes the flue gases get so cool that the water vapor in the gas condenses out.When this happens, even more energy is recovered from the condensing vapor, and the efficiency gets higher still. If it is time to change your boiler, then the first thing is to decide what type of boiler you need.

Free replacement for old boilers is available under ECO (Energy Company Obligation) scheme. It offers free survey and if the boiler is approximate more than 8 years old. It offers free replacement with A-rated condensing boilers. In non mains, the replacement is allowed for LPG/Oil boilers. It is an initiative by affordable warmth to lower down energy bills cost of lower income households.


We are certified for insulation services like cavity wall, external wall and loft insulation. We work under ECO (Energy Company Obligation) schemes which offer free funding for few wall and loft insulations.


We offer cavity wall extraction process that includes removal of previous improper installation instances from wall cavities. Improper instances occur due to unexpected circumstances or selection of wrong property type.
