System Boilers: The Benefits and Drawbacks to Help you Decide

Individuals choose to change their boiler for a variety of factors. It may be that their existing one is malfunctioning, old or ineffective.

When you’re choosing a new boiler, you have numerous options offered. These include combi boilers, conventional boilers and system boilers.

Each of these boilers operate in various ways and are matched to different home sizes.

System boilers are often known as sealed system boilers. Like conventional boilers they have warm water cylinders, but they do not have cold water tanks. System boilers are usually set up in bigger domestic or business homes.

To help you decide whether you need a system boiler in your home, we have produced a list of their benefits and drawbacks.

Pros

Can provide hot water to a number of taps

System boilers can supply hot water to a number of taps at one time. They can do this without setting off a drop in water pressure. This is because system boilers heat water ahead of time, so when hot taps are turned on the hot water can right away go to any place it’s needed.

This contrasts with combi boilers, which don’t heat water in advance and as a result struggle to heat adequate water for numerous taps at the same time. This can lead to water that is not at an adequate temperature or low in pressure.

So while combi boilers are fantastic for smaller sized homes, system boilers are better suited for larger domestic or commercial properties, where hot water may be needed from numerous taps at the same time.

Takes up less space than a traditional boiler

System boilers use up less space than standard boilers. This is since they do not have a cold water tank, whereas standard boilers do. So if you wish to install a system boiler in your home, you simply need to find space for a hot water tank and the boiler itself.

Compatible with solar hot water heater

Like standard boilers, a great deal of system boilers work with solar water heating systems. This is due to the fact that they have hot water tanks, which can be adjusted or changed to heat water using solar energy.

Combi boilers do not have hot water tanks, and are therefore not generally compatible. So if you wish to utilise solar water heating, a system boiler might be an excellent choice for you.

Cons

Only warms up water ahead of time

System boilers just heat water ahead of time. This means that you have to have your boiler on a timer that you can set to heat water for when you generally need it, or you’ll have to keep in mind to turn it on before you need it.

This usually works well for individuals who have routine regimens, nevertheless if you desire to use warm water at various times on different days, a system boiler might not be for you.

Hot water can run out

Another downside to the way system boilers work is that the hot water they produce can run out. A system boiler’s hot water tank can only store a certain amount of water, so if you utilise a huge quantity of hot water at one time it may end up running out. And as system boilers can only heat water ahead of time, you’ll have to wait for the hot water tank to fill prior to using hot water again.

Takes up more space than a combi boiler

System boilers take up more space than combi boilers. This is due to the fact that combi boilers do not need a hot water tank, whereas system boilers do. So if you have limited space in your house, a system boiler might not be the absolute best choice.
