Is a Combi Boiler Right for You?

4.3When it comes to a new boiler, one type of boiler is vastly more popular than others. The combination boiler or the combi boiler is the most common boiler choice today. But given that the cost of a new replacement boiler is high, you need to know that you are making the right decision when you purchase a combi boiler. Is a combination boiler right for your needs? What advantages and disadvantages does a combi boiler have over the traditional, conventional boiler?
Differences Between the Combi and Conventional Boilers
The conventional boiler, or regular boiler, has a boiler plus a water storage tank. The boiler takes water and heats it, storing it in the tank. The combi boiler takes water for heating directly from the main supply. There is no need for a separate tank, hence the name “combination”.

Advantages of a Combi Boiler

When you use a combination boiler in the home you have unlimited hot water, on demand. With the conventional boiler you must wait for the water in the tank to heat up and if you use all the water in the tank you have no more hot water and need to wait. The combi boiler has the benefit of always supplying hot water for showers and baths. The water pressure remains high, so you don’t need to fit a separate shower pump to ensure the shower pressure is strong enough. You also do not need space to keep a storage tank. This space need can be considerable, and if you do not have an attic there may be no room for a tank. The combi boiler is compact and fits into an airing cupboard or a kitchen cabinet.
For boiler installation London engineers often recommend the combi boiler because it is quick to fit, with the minimum of new pipes needed. Installation can be carried out with the minimum of fuss.

Is a Combination Boiler Right for Me?

In some cases it would be more appropriate to fit a conventional boiler. For example, if your home is larger and you have more than one bathroom a conventional boiler may be best. This is because you experience a drop in water pressure if more than one tap is operating at the same time. For a home with several bathrooms, and lots of people in the family, it can be difficult to use a combi boiler successfully. If you have lots of space for the tank it may be better to fit the conventional boiler.
Or, if you do use the combination boiler, try to limit your use of different taps or appliances at the same time. If you have concerned about this aspect of the boiler, ask your heating engineer to recommend the best combi boilers to deal with the issue. Some boilers are better than others at regulating water pressure. There are a range of boilers available on the London market depending on what you are looking for in terms of water conservation, heating cost, and size of boiler. Ask your London heating professional for more advice.
