Combi Boiler

The boiler is essentially the beating heart of any home. It’s the ever-lasting furnace that keeps your rooms toasty and your showers steamy, working tirelessly in the background.

Unfortunately, we don't realise how much we value our boilers until they conk out on us. What a thankless life they lead.

The combi boiler (cool slang for combination boiler) is the energy efficient heating and hot water solution that is replacing most conventional boilers in the UK and is perfect for households that need all the space they can get.

Originally they were only intended for use in one-bedroom or two-bedroom homes, but recent models are capable of supplying much bigger properties meaning it's an ideal option for just about any home.

Advantages Of A Combi Boiler

Have a blast with a power shower.

Since a combi boiler doesn't require a cylinder or storage tank it releases water directly from the mains, so you can enjoy a proper non-trickle shower without needing to buy an extra pump.


Extra Living Space.

Gas combi boilers are renowned for being compact and lightweight which means there’s more space in your home for something more enjoyable. With hot water cylinders and cold water tanks out of the way, think of the exciting objects that could take their place. It might give you the opportunity to convert your loft, and your airing cupboard could just become a nice place to stand in.

Quick Installation.

When you buy a new boiler for your home, the initial cost of installing it can be pretty hefty, often being more costly than the unit itself. A combination boiler however takes much less time to install since it has everything it needs tucked away inside and less pipework. It’s simple: a shorter installation time means a smaller fee.

Green Machine.

With other types of boiler, energy is wasted on keeping the tank of water permanently hot. Heat escapes (it always does), and the boiler has to use more energy to replace it. With a combi boiler, water is heated only when it is required, meaning barely any energy is wasted. Benefiting you and the environment.

Electric Or Gas Combi Boiler?

Despite their many advantages and versatility, the combi boiler isn't capable of powering itself. So the onus is on you to provide the power, but which is best?

Electric Combi Boilers

Electric combi boilers work similarly to a gas combi in many ways, it performs all the usual tasks of a gas combi boiler but using only electricity to power your central heating and hot water. You can use an electric combi boiler for hot water only, but usually it will meet all of your heating needs.

A big reason given by many customers who opt for an electric is the environmental impact. When you go electric, you no longer burn gas in your home and release it into the atmosphere. It's not 100% clean but it is the most eco-friendly central heating system that you can have, being far better than gas boilers for the Earth.

If you thought combi boilers were compact, wait till you see an electric combi boiler! As well as being the best for efficiency, it is also the most compact type of boiler you can get since it requires less clunky parts meaning you can slot it right in one of your kitchen cupboards.

Gas Combi Boilers

Electric combi boiler running costs are the main sticking point when it comes to deciding between an electric or gas boiler. Gas is a much cheaper fuel to use, meaning that you could end up paying a lot more for your energy bills following an electric combi boiler installation.

Natural gas boilers are the most commonly installed heating system in the UK. As of 2020, around 80% of homes in the UK rely on gas central heating. Properties that aren’t connected to the gas network can still have a gas boiler installed too though. However, rather than natural gas, it will need to run on LPG. LPG is a natural gas alternative which is a liquid.

It's also worth noting that although a gas combi isn't quite as efficient or eco-friendly as the electric boiler, they are still A-rated for efficiency and are better for savings and the environment than say a system boiler or open vent gas boilers.

Additionals things to consider

So we know how combi boilers work now, but what's the best choice from our vast range of efficient heating products? Well, there are a few things that are worth evaluating first, so you know what to look out for before purchasing.

Energy Efficiency

A boiler’s ‘energy efficiency’ refers to the percentage of energy created that is used by your house vs the energy that goes to waste. Naturally, the more inefficient the boiler, the more money you’ll be spending to heat your home. Therefore, it’s really important that you get a high-efficiency boiler. The good news is, all UK boilers now must have 92% efficiency, so most new ones are really good but combi's have the potential to go much higher. Some combi boilers are smart enough to reduce their energy usage on their own.

Output

Measured in kilowatts (kW), a boiler’s output refers to how much hot water it can generate at any given time. If you live in, say a 4 bedroom, 1 bathroom house, then a 24-27kW combi boiler will probably be sufficient, capable of running about 10 radiators and one bathroom. Meanwhile, in a larger home (i.e. three or four bathrooms), a 28-35kW boiler would be more suitable.

Size

Most conventional natural gas boilers take up a fair bit of space. If you have one you'll understand, so it's important to take into account how much space your new heating system will take up. Fortunately combi boilers, like mentioned, are usually compact and you'll find might even fit in a kitchen cupboard.
