Pros and Cons of a Combi Boiler

Combi boilers, also known as combination boilers, having seen their popularity increasing rapidly in the United Kingdom over the last few years. More than 70% of households prefer to install combi boilers over the tank system or hot water boilers.

There are significant features that have enhanced the popularity of combination boilers across the UK, making it the most popular boiler. Combi boilers offer a variety of benefits, and that's why they are preferred.

Benefits of Combi Boilers

More Efficient

When compared to standard boiler models, they tend to be more productive. Combi boilers are relatively affordable as they can save you more than £300 annually if you decide to replace your standard model with a combi boiler.

Affordable

When compared to traditional boilers, combi boilers are easier to install; which means installations are affordable. Finding the replacement parts of combi boilers is easier when compared to traditional ones in case of a problem.

Faster

Since there are no water tanks for heating up, combination boilers can offer a sufficient supply of hot water within a reasonable amount of time.

More Compact

Combi boilers assume little space when compared to standard heating systems because a separate water tank is not necessary. Making them perfect for households with space limitations.

Safer

The cold water stored in a combination boiler system is safer for drinking since it comes from the source. Older systems keep the cold water in tanks even before it's piped around the household.

Fewer possibilities of experiencing pressure concerns

A combination boiler system is not prone to low pressure, and there are fewer chances of suffering from airlocks since the warm water is pulled from the primary source.

Cleaner

A combination boiler is not susceptible to the build-up of sludge. The water is drained from the primary source and not stored in a cylinder or tank where it can attract dust and debris.

Easier to Service

The rise in popularity of combination boilers serves as an indication that most boiler experts are well trained in matters concerning repair as well as servicing them.

Combi boilers, like any other heating systems, have their drawbacks. Irrespective of their popularity, there are numerous concerns you have to keep in mind when thinking of replacing your boiler.

The Negatives of Combination Boilers

Dependence on Water Pressure

Combi boilers function correctly in the presence of the appropriate pressure levels from the mains supply. When having a brand new boiler, you need to consider pressure being generated by the mains in your area before installing your combi boiler.

Limited usage

Combi boilers cannot run multiple flows of water simultaneously. It's also not possible to open the hot water tap while taking a shower. If you reside in a household with multiple bathrooms or with many people, this can become an issue.

Absence of Immersion Heater

Since there are no water tanks, a breakdown of the combi boiler will leave you with no warm water or central heating.
