Combi boilers are the latest in boiler technology and they have been growing in popularity recently.

It’s estimated that about 70% of households in the UK have a combi boiler and we can expect these numbers to continue increasing. They still remain a mystery to many people who may still be wondering what they have to offer, however. Combi boilers have many advantages over traditional options, but they aren’t for everyone, hence why you need to understand their specificities first. Let’s take a closer look at what combi boilers are and whether they would be a good option for your property.

What Are Combi Boilers, Exactly?

The way combi boilers work is pretty simple. They use heating elements to heat water straight from the main supply without any need for a separate water tank. These systems tend to be much smaller than other water heaters and combine both central heat and water heating into one compact unit, hence the name, ‘combi’.

What are the Benefits of Combi Boilers?

The biggest benefit of combi boilers is that that they do not require as much energy to run. Water doesn’t have to be constantly heated to be maintained at a certain temperature. A lot of people already have the habit of turning off their boiler before going to sleep to prevent it from heating water unnecessarily. You don’t need to do that with a combi unit.

No matter how energy efficient your traditional boiler is, it won’t stand a chance against a combi boiler. It has been estimated that making the switch could allow you to save as much as £300 per year on heating. Not only that, but these units are much less complex than most traditional heaters. This means that they cost less to buy, install, and repair as well.

If you want to find the best combi boiler unit for the price, we would suggest you check out Boiler Central. They not only run down the best models on the market, but the best brands as well. They show the pros and limitations of each as well as things such as warranty, energy rating, and controls among others.

The other benefit of combi boilers is that you will never have to deal with the tank running out of hot water. If you’re the only person using the water, you could have hot water infinitely. Another benefit is the fact that they are so compact. This makes them perfect if you have limited space, as is often the case in some homes.

A home with a combi boiler could also be easier to sell because of the benefits and lower maintenance that comes with it. Speaking of maintenance, combi boilers are much cleaner since no sludge will build up like with other systems, so that’s another point in their favour.

Do they Have Any Drawbacks?

Unfortunately, there are some drawbacks to combi boilers, and it’s very important that you understand what these are before you have one installed. The biggest issue with combi boilers is that they can’t supply many uses at once since they don’t have a tank and instead heat water on demand. You won’t be able to run more than one shower at a time, and you won’t be able to use hot water for cleaning while someone is taking a shower either. So, you will have to look at other options if multiple people routinely use the hot water at once in your home. Know, however, that you always have the option of installing parallel combi boilers, but this could end up costing you more than you expected.

Another issue with combi boilers is that you will be dependent on your mains pressure. If you have poor pressure where you are, the unit will not perform as well. This is why you will need to take a look at the mains pressure in your home before you consider the option. This also means that you won’t be able to have power showers as power will be dictated by your water mains.

Also, since there is no water tank on these systems, you might have serious issues if it breaks down. This means that you could run out of hot water and heating at the same time. Having a tank also buys you time if it breaks down as the water in it will remain hot for a good while.

If you were still in the dark about combi boilers and their benefits, we hope we were able to clarify a few things for you. Try to learn as much as you can about these units and don’t hesitate to speak with a technician about them today if you are considering having one installed.
