Combi Boilers 2020 boiler

If you’re looking for a residential boiler that’s likely to be the most cost-effective for you, it’s worth looking at a new boiler.

Combi boilers are the most common boiler types to be bought in the UK.

Combi boilers are generally the most cost-effective and efficient boilers around.

Combination boilers control the hot water and the central heating, hence the “combi” name.

These boiler types are especially popular for anyone conscious about their own environmental impact and want to do something to reduce their carbon footprint.

Combi boilers do not have any extra parts of the boiler. It is a 1 unit system.

That’s another thing that makes combi boilers appealing to homeowners; it means they don’t take up much storage space in the home. Often they live in a standard kitchen cupboard or can be wall-hung.

Installing these types of boiler keeps costs low as they are simple to install.

The downside of these central heating boiler types is they are not great with pressure. You can’t run water from more than one tap or shower at the same time.

Pros and Cons of a combi boiler:

Pros:

  • Unlimited heating and hot water on demand for homes with up to 4 bedrooms.
  • Only heats the water you need at a specific time, making it cost-effective and eco- friendly.
  • No cylinder needed so will fit in a kitchen cupboard.
  • It’s easy to find what size boiler you need for your home.

Con’s:

  • Water pressure can reduce if you run more than 1 tap at a time.
  • No backup source of hot water if the boiler breaks down.
  • Very rarely will be compatible with solar panels.

 

System Boilers system boiler

If you have multiple bathrooms with a high demand for hot water, a system boiler may be the boiler for you when choosing a new boiler.

System boilers are better options for some people because they allow you to run multiple taps or showers at the same time.

If you have a couple of showers in the home that people tend to use around a similar sort of time in the morning, a system boiler will make that possible where a combi boiler doesn’t.

System boilers tend to be quite economical to run, and they are relatively compact too. This boiler type would mean the boiler would live in a kitchen cupboard and then the hot water cylinder would live in the airing cupboard.

They offer a constant supply of hot water on demand, and you won’t need to worry about low boiler pressure problems.

Pros and Cons of a system boiler:

Pros:

  • Faster and more simple to install than a regular because all components are built into one unit.
  • Saves space because no cold-water tank is needed.
  • Faster and more effective hot water to multiple taps at once.

Con’s:

  • If the cylinder is not insulated well, it may lose heat.
  • Storage will be needed for the cylinder.
  • Hot water ready on demand will depend on the size of your cylinder.

 

Conventional Boilers conventional boiler

Conventional boilers are the oldest type of boilers on this list, and that’s why they’re also known as traditional boilers.

Conventional boilers are often known as regular boilers.

They use both a hot water cylinder in the airing cupboard and a cold water storage tank in the loft. Therefore meaning they can take up quite a lot of space in the home.

If you have that space available, you shouldn’t necessarily rule out this option because it does offer some benefits that other types of boilers can’t offer as well.

These boilers are very good at supplying water to different parts of the home at the same time, which is something that combi boilers really struggle with.

Conventional boilers are also by far the best option for homes that already have problems with low water pressure.

They are also compatible with a wide range of energy-efficient options such as solar thermal systems.

However, water has to be heated, so it’s not available on demand.

Pros and Cons of a conventional boiler:

Pros:

  • Hot water can run from more than one tap at a time.
  • Heat only boilers can work even if boiler pressure is low.
  • Compatible with solar panels.
  • If you already have this system, a few pipework changes could be possible for a new installation.
  • An electrical immersion heater can be installed in the cylinder, so if your boiler breaks down; you still have hot water back up plan.

Cons:

  • Takes up a large amount of space.
  • Could be more costly to install.
  • Could be more complicated and time-consuming to install.
  • The amount of hot water ready at one time will depend on the size of your cylinder.
  • The cylinder has to be well insulated, or it will lose heat.
