3 Combi Boiler Benefits You Didn’t Know About

Combi boilers out there have several benefits that may make them the perfect option for your needs





Are you in the market for a new boiler? If so, you may be wondering if a combi boiler suits your home. A combi or combination boiler provides central heating and instantaneous hot water. It takes cold water directly from the main water line, heats it, and delivers it to the hot water tap.

Choosing a Combi boiler depends on how much water your household uses at once and how much space one has to install the boiler. However, the best Combi boilers out there have several benefits that may make them the perfect option for your needs. Here are three benefits of combi boilers that you may not have known about.


1. Combi boilers are more efficient than traditional boilers

Combi boilers can heat water and warm homes through radiators. They are considerably more efficient than traditional boilers, saving energy by only heating the water when needed and allowing you to enjoy hot water without waiting for a large cylinder to heat up.

Essentially, combi boilers heat water on demand directly from the mains. Hot water is delivered through your taps and showers at mains level power, allowing you to enjoy high-power showers without needing a storage tank like other traditional boilers.
A lack of a cold water unit also reduces the risk of pipes freezing during winter. Combi boilers are very efficient and cost-effective as they heat water instantly rather than storing heated water in a tank, which can lead to wasted hot water.


2. They’re ideal for apartments and small homes

Combi boilers are smaller in size with a wall-hung design, making them ideal for apartments and small homes. With no tanks in the loft, you will enjoy less pipework and a quick installation to get it up and running in no time. It is also easier to find replacement parts if a problem occurs.

Moreover, combi broilers have “hot water priority,” so their radiators have no heat output when hot water is being run. They are also very convenient for small homes because they do not require a hot water storage tank or a cold water feed tank. Those tanks are bulky and take a lot of space in the loft or basement.


3. You can save money on your energy bills with a combi boiler

Combis are relatively affordable, making them a cost-effective choice for homeowners on a budget. Since water is heated in small quantities, you save money compared to traditional boilers, which heat vast amounts of water even if you simply want to wash your hands.

According to Energy Saving Trust, you can save up to 40 percent on energy bills if you replace your decade-old boiler with an A-rated combi boiler. Combi-boilers have a smaller carbon footprint when compared to conventional boilers, and they are available in both gas and electric models, so you can choose the one that best suits your needs. Better yet, if you combine a combi boiler with solar panels, you can save even more money on energy bills.



Combi boilers are quick to install and provide hot water on demand. They also don’t have storage tanks or cylinders, so they’re ideal for small homes. However, it’s important to consider the number of bathrooms in your house to choose the boiler type and size that suits you. Expect a higher water demand if you have more bathrooms, so opt for a large combi boiler.
