Compare System Boilers

System boilers provide good water pressure along with a constant supply of hot water. System boilers are a great option for some households as they allow you to run several taps, baths or showers at the same time. For this reason, they are ideal for larger properties, guest houses and hotels.

System boilers are closed system boilers, typically consisting of two parts; namely a boiler to heat water as well as a hot water cylinder to store hot water. The central heating boiler warms up your water which is in turn stored in the hot water cylinder for later use.

System boiler cost

When you compare system boilers, expect the cost to start at around £650, rising to in excess of £1,500. Remember, the cheapest boilers may not be the best boilers for your property. It’s really important to ensure that the system boiler you select is big enough to cater to your household’s needs.

Another factor to consider as you compare system boilers is the cost of installation. Prices typically start in the region of £150 to £2,000 and will depend largely on the size of the system required and whether a hot water cylinder is also needed. 

Installation costs also vary from tradesperson to tradesperson. Some will charge you more than others. Some may offer a fixed fee, whilst others will offer an estimate. Make sure you are being offered a fair price and a professional service – don’t get caught out. And remember – in the UK, regulations state that any gas installation needs to be conducted by a Gas Safety registered installation engineer.

Why you should choose a system boiler?

If you have a larger property with two to three bathrooms where several people may need to use hot water at the same time, a system boiler could be the right choice for you.

Energy-efficient

A new system boiler will typically be a condensing boiler, meaning that it uses a condensing technique to heat the water. These boilers are highly energy-efficient, extracting over 90% of the heat from the fuel that they burn.

Multiple taps

A system boiler stores hot water in a cylinder, which means that multiple taps or showers can be used at once without compromising on water pressure. Their capacity to cope with high levels of usage makes them perfect for larger properties.

Economical

When compared to other types of central heating, system boilers are pretty economical. This is because they store hot water in water cylinders. A new ‘A-rated’ energy-efficient system boiler will reduce the average heating bill by up to £200 per year.

Reliable

System boilers are known for being reliable, so you don’t have to worry as much about paying out regularly for maintenance costs. You can rest assured that with the right boiler for you, these can be kept to a minimum.
