What is a System Boiler?
System boilers, unlike combi boilers, come with a separate unvented hot water storage cylinder allowing the system to supply hot water continually throughout a property.
This is in contrast to combi boilers, which can only offer hot water on demand.
Given how system boilers work, they are well suited to larger properties with a high heating and hot water demand.
The average system boiler is somewhat more expensive to install than a combi boiler.
Cost of Installing a System Boiler in the UK
It is likely to cost somewhere in the region of £1,500 to £3,000 to have a system boiler installed.
This would factor in both the price of labour and the standalone cost of the boiler unit. Some additional expenses may apply.
Of course, how much you’d actually pay for a system boiler will depend on a whole host of factors.
The most important cost factor is the standalone price of the system boiler itself.
Of course, the higher the output or/and the quality of the boiler, the more expensive it is likely to be.
However, beyond that, the total cost of having a system boiler installed would also be shaped by the ease of installation, your property location and whether or not you are converting from one type of boiler to another (e.g., combi to system boiler) or you’re looking for a like-for-like replacement.
The reason that the location of your property can shape the cost of installation is that labour prices differ across the UK.
Labour prices tend to be below average in northern England, Scotland and Northern Ireland whereas they tend to be above average in the southeast of England.

How Much Does It Cost to Run a System Boiler?
The cost of running a system boiler will primarily depend on the fuel source, the power output of the boiler in question and its energy efficiency.
With prices set by the Energy Price Guarantee, depending on how you pay for your heating, you’d pay around £0.10 per kWh if using natural gas or £0.34 per kWh in the case of electricity.
However, what you’d end up paying per month or annually would depend on the various cost factors mentioned above as well as any other applicable cost factors.
