What is the right combi boiler for me?

The combination or ‘combi’ boiler takes its name from its dual function: it’s a high-efficiency water heater and a central heating boiler combined in one compact unit. They provide heating and hot water directly from the boiler, which means almost immediate hot water. A combi boiler will suit your home if… You have a smaller property, perhaps with a single bathroom, and fewer people in it. This is because the smaller unit means a big tank or cylinder will otherwise take up valuable space, and water pressure can decrease if more than one person uses the water.

Which combi boiler should I choose?

There are two main things to consider before you buy a combi boiler, they are 1) lower tap flow (if more than one tap or appliance is being used at a time, a very slight pressure decrease can occur) and 2) whether you have more than  one bathroom. If you do then you might need a larger model. These tend to be better at mitigating any pressure loss if the system is under any strain. Because of the clever space-saving design and swift water heating function, combi boilers are the most popular type in the UK, accounting for over half of all new domestic boilers installed every year. A combi boiler works by supplying limitless on-demand central heating and hot water directly from the boiler. The water comes directly from the mains, so that water is constantly available, and at a high water pressure.

Vaillant Combi Boiler Range

What are the main benefits of getting a combination boiler?

main benefits of getting a combi boiler in 2016

Quicker & cheaper installation

There are fewer parts and pipes in a combi central heating system; they tend to come near enough pre-assembled. Installation tends to be fairly straightforward and no tank in the roof space means less pipe work. Time is money, so less installation time means more money staying in your pocket.


No bulky storage container, and no need for a separate cold water tank or hot water cylinder in the loft. Combination boilers tend to be smaller, meaning less space is taken up. They fit easily into kitchens and storage cupboards. This type of boiler can be especially helpful if you are a landlord and have tenants living in your property. We offer a full boiler and service plans for Landords.

Better water pressure and power showers

Because combinations use water that feeds straight from the mains, the pressure stays high even after extended and heavy usage and hot water is delivered – almost immediately – at mains pressure with no need for a pump so showers can be enjoyed all the time.

Bigger, more extensive range

Combi boilers are growing in popularity, because of this, boiler manufacturer’s like Vaillant and Worcester offer a wide range of models to suit any home. Well-sized boilers are also more efficient than over or undersized boilers.

What should I consider before I buy a new combi boiler for my home?

Do you need a complete overhaul for the old boiler stocked away in your airing cupboard?

Are you really fed up with the starting problems that are a nuisance for your boiler? If you answered yes to any or both of these questions, you are ready to invest in a new boiler. Even better, choose a combination boiler to get a more technologically advanced result for your homes or offices.

The gas combination boiler or also known as the Combi boiler is the most efficient of the lot. For starters, it is a combination of a traditional heating unit and hot water cistern. So you can run your central heating and get hot water with the installation of just one device!

This saves up a lot of space. So, it is an ideal solution for houses with short storage spaces. You only need a space for the device and do not have to put in a separate cylinder for hot water or a feed cistern for the cold water. There might be just one small con related to the device. You will have to wait for a short time after turning on the tap for the water to turn hot. This of course also depends on the boiler’s model and capacity of how fast it can heat the cold water.


How to find the best combi boiler for my home

The best way to find an ideal combination type boiler is to lead the search with features. You need to know what your home needs from your boiler, and then use that as a reference to make an informed decision.

Boiler warranty

Look for at least a 2-7 years of warranty on your product. It is important because boilers are heavy heating equipment and they do not come at cheap prices. You should be able to look at it as a long time investment and not worry about continuously replacing the device at frequent intervals.

Access to authentic fittings

You need to buy a brand that also has easily available authentic fittings for the device. This is because you will need to maintain your device down the line and you should not have to scour the market all the time to find a few fittings when you need to replace them.

Reviews online

Look for customer and expert reviews online. It is the safest way of finding out about any new product before you buy it. For boilers it is doubly important because being heavy equipment the more research you do before the purchase, the lesser the chances of having to replace the device later.

Energy efficiency

Always find a model of boiler which suits the energy needs of your home. So, if you have a big family and need a combi boiler that provides sufficient hot water for all members, you cannot opt for a smaller model in the series. It will not be energy or cost efficient over long term.

Returns policy for the brand

The brand of boiler that you opt for should have a good returns policy. Often consumers, especially the ones outfitting their homes for the first time, would have some trouble with finding the best combi variety boiler right off the bat! They should have a good peace of mind when buying the product, knowing that if they find it unsuitable and need an upgrade or an exchange, they can return the product easily.
