Condensing Boiler Prices & Installation Costs Guide 2024

Condensing combi boiler prices guide for 2024

A condensing boiler heats the water in your boiler by using some of the heat produced by the boiler, which would typically be released into the flue.

As a result, the boiler is much more effective and requires less energy to maintain hot water. The most popular type of condensing boiler is a gas combi boiler, but there are other types as well, including gas boilers that produce only heat.

You can choose a combi boiler with a lower output, typically up to 30kw, if your house is smaller and only has one bathroom. You might need a combi boiler that is more powerful than 30kw if your house is bigger.

This is to make sure it is capable of keeping all the radiators in your home hot and at the same temperature while supplying hot water to your taps with good pressure.

Condensing System Boiler Prices

Every new boiler is condensing, just like combis. Having a separate hot water tank distinguishes a system boiler from other types of boilers.

This has no bearing on whether the boiler in question is a condensing boiler or not because it is the primary device in your home that pumps water to the faucets.

For larger homes with higher hot water demands, condensing system boilers are more appropriate. They can easily supply hot water to two or three showers simultaneously without experiencing any loss of boiler water pressure.

A larger home is typically more appropriate because it requires more space to house a hot water storage tank, which they have. Consider a condensing combi boiler for better efficiency if you live in a smaller house or a larger house but need to create some space.

If you already have a system boiler, it might be more economical to simply replace it with a new one rather than switching to a combi boiler. Expect to pay a fee to have all of this changed over if you want to switch to a combi. Given that most combi boilers are more cost-effective when used properly, it might be worthwhile in the long run.

The cost of condensing system boilers varies according to their power

Make sure the condensing system boiler you purchase is the appropriate size for your house. A higher output (KW) boiler is typically required for larger homes. This indicates that it can easily send hot water at the desired temperature to each radiator in your home.

You might need a system boiler with a 25kw capacity if your house is smaller. Larger homes would need an output of at least 26kw. In general, the price in each range is increased when the output is higher.
