What is a system boiler & how do they work?

A system boiler is unit that heats up water for radiators, taps, showers & anything else linked to your central heating system for you to use. A system boiler has two main parts to it. The first part is the unit that the mains water enters and heats up the the water.  The 2nd part is a large storage tank where any hot water that has been heated up is kept until it is needed at any outlets like taps and showers. The radiators are heated up on a separate closed pipeline as and when in the same way.

You need to ensure that you do not mistake a system boiler for a regular boiler which has 2 tanks, one at height usually in a loft space. If you are unsure you can always get a heating engineer to come round and have a look. If you have no tanks at all, you will have a combi (combination) boiler. Combis are the most common boiler in the UK

So, if you think you have a system boiler and want to know if you should keep it, or change to another boiler e.g a combi boiler, take a look at our guide to system boilers and why you should of shouldn’t get one. We’ll even give you a guide on some of the best ones to buy along with guide system boiler prices for some of the top manufacturers in the UK right now such as, Viessmann, Worcester Bosch, Ideal, Baxi, ATAG & Glow Worm.

 

What are the advantages & disadvantages of a system boiler?

 

Here are some of the main advantages of having a system boiler for your hot water & central heating system:

System boilers are great for homes with high hot water demand.

If you have a larger home with 4 or more occupants then you should really consider a system boiler. The fact your home is larger will also mean that you have space for the hot water tank which is required to store the water. If you think you use ALOT of hot water at peak times such as morning and evenings between you then you should definitely consider a system boiler.

They can be super economical.

If your hot water tank is insulated properly and you choose the right size boiler for your home, you can have years of low cost heating. Nearly all system boilers built in modern times are also condensing system boilers, which means that they re-use some of the wasted energy is re-used within the boiler to continue heating up your hot water. Very clever. They can do this very quickly and an in-built pump ensures that hot water is distributed quickly around the system, saving time and money!

They are easy to install

If you already have a system boiler, or want to get rid of that big tank if your loft, then installing a system boiler will be a doddle. You can keep all the excellent hot water attributes flowing through your home and pay less to have one installed in your home as you will just be “swapping” your boiler! If you want to get rid of every tank in your home, consider a combi boiler, but also consider it may not be the best type for your home.

Better water pressure at your taps & showers

Because a system boiler uses the mains water supply, you can get a much improved flow rate at your taps and showers. Who doesn’t love a power shower. If you have a regular boiler you will no longer have to rely on gravity out of your tank. Plus there won’t be one anyway if you change to a system. Happy Days!

Solar panels can be used to heat the water in your tank too

How system boilers are set up means that you can also use your solar energy to warm up your water. You need to ensure that your boiler and tank are compatible but if not there are always ways to make sure that they are. This is a great idea towards being self sufficient in the future and can save you hundreds of £££’s every year.

 

Some disadvantages of a system boiler installed in your home:

They have a hot water tank which takes up space

As we have said, system boilers need a hot water tank. These hot water tanks aren’t small. You will need somewhere to house this tank, usually in an airing cupboard or hidden space. But if you don’t have that much room, you may want to look at a combi boiler which is just a single unit that does it all.

You may have to wait for your hot water!

If you don’t have a hot water tank big enough or there is an excessive amount of hot water used in your home, you can use up all the hot water. If this happens, you will have to wait till the tank is full again and at the right temperature. Not something you want to be doing when you’re in a rush to work on a morning!

All in all, if you get a tank big enough you shouldn’t really have any issues, but then a large tank, requires more space. It really does come down to ensuring you get the right size boiler and tank for your home.
