FAQs

What is a combination boiler?

A combination boiler is the most popular type of hot water system in the UK. Comprised of an energy efficient condensing boiler, a storage cylinder and a pump unit combination boilers heat water and generate hot water at the same time.

Combination boilers are more efficient than traditional boilers because they use less fuel to heat the same amount of water as conventional systems, saving you money on bills. They're also more economical than storage heaters because factors such as flushing out pipes regularly to remove limescale can reduce your costs by up to 50%.

How does a combi boiler work?

A combi boiler is a water heating system that provides both central heating and hot water. The name ‘combination boiler’ comes from the fact that it is a combination of two elements; an electric storage heater, and a gas or oil burner.

Combination boilers use less energy than traditional systems, by using several sources of heat to provide both central heating and hot water. This results in higher levels of efficiency overall.

Combination boilers can be more cost effective in terms of running costs too, as they don't need separate boilers for hot water and space heating purposes like some other systems do (such as an electric instantaneous heater).

What is a combi boiler?

A combi boiler is a central heating system that uses a heat exchanger to heat water. Unlike traditional boilers, combination boilers typically use less energy to heat the same amount of water and are often more efficient when compared to other methods of heating your home. Combination boilers can be installed as standalone systems or in conjunction with other technologies such as solar panels and inverters.

Are combi boilers efficient?

A combi boiler is a combination of an electric storage heat pump and gas boiler. With a combination boiler, you can use the heat pump for heating your water in the winter months and use the gas to heat your home during the summer. Combination boilers are more efficient than traditional electric storage systems because they can capture wasted heat from the hot water cylinder and transfer it into your home’s heating system.

This is how efficiency ratings work:

Each rating has two numbers separated by a slash (e.g., 10/11). The first number refers to “cold weather” energy efficiency while the second number refers to “hot water” energy efficiency.

For example, if you see an 8/10 rating on an item with this format, it means that this product would consume 80 percent less energy during cold weather conditions compared to standard products in its category (8). It also means that this product would produce 10 megajoules per kilowatt hour of electricity when operating at full capacity (10).

How much does it cost to run a combi boiler?

  • The cost of running a combi boiler depends on the size of your boiler, and the size of your house.

  • A combi boiler is more energy efficient than a standard boiler.

Combi boilers are the most popular for private homes.

Combi boilers are the most popular choice for private homes because they're an efficient way to supply both hot water and heating. They're relatively simple, and there's no need for separate systems or equipment.

Combination boilers can be used to heat homes with either a high demand for hot water or a low demand for hot water depending on what you need, you'll get your money's worth out of this type! You can have these installed at any time during construction, or even retrofitted into older properties where additional heating isn't needed.

Combination boilers work by mixing the gas from natural gas burners with an extremely heated stream of water from an electric pump (which is attached directly onto the appliance).

This gives off much more heat than either system would on its own while traditional heating methods require multiple pieces of machinery connected together through plumbing lines in order to provide adequate warmth throughout your home so it makes sense why so many people prefer them!


Final thought

When you consider the cost savings, comfort and convenience of having a combination boiler hot water heater installed in your home, it’s easy to see why this is the best option for most homeowners.

With so many different brands and models on the market today, it can be difficult to make an informed decision about which one will work best for your needs but we hope that our guide has been helpful in narrowing down those choices!
