System boiler installation in North London

We recommend this type of boiler installation in homes whit multiply bathrooms.

  • This boiler can deal with a high demand for hot water, so if you recognise yourself, this is the best boiler type for you.
  • Supplying water to more shower at the same time with the same efficiency and power, to serve more people comfortably in the house.

It is ideal for homes with no space in the loft.

» For the boiler, we only need to install 1 storage cylinder, which gives more free space in the loft.

» System boiler can replace the regular boiler. And also we can remove the tanks from the loft saving up a lot of space.

» The boiler is heating your radiators. The hot water produced and stored in a separate storage tank.

» This types of boilers are like a regular (conventional) boiler.

» The big difference is that the system boiler takes the water supply direct from the mains.

» This boiler is a compact unit but it will supply a high volume of domestic hot water.

We will help your dreams come true by boosting your system and have a powerful pressure in your shower! You will have it all.

Below you can see a system boiler installation diagram:


The system boiler advantages:

  • We don’t have to install a cold water tank in the loft, saving up a lot of space.
  • Easier to install compared to other types of boilers.
  • This boiler responds quick to your hot water demand, because of a built-in pump.
  • You can use more shower at the same time, without losing any power at the shower.

The great performer system boiler has a few disadvantages:

  •  We only need to install one hot water tank, and this can take up a little more space.
  • You have to use a storage tank in the airing cupboard, your hot water capacity depends on the tank size! If you are used all of your hot water, you just wait a little longer to heat up in the storage tank!
  • You will have some heat loss on the pipes, but you don’t have to worry about this, because we will put isolation on them!

Heat only boiler installation in North London

Also called a conventional, traditional or regular boiler. This is the oldest system in the UK, and some places are still working fine.

Regular boilers are ideal for more than one bathroom. Where the water pressure is low and where is a high demand for hot water.

We upgrade this heat only boiler with a system or combination boiler. We supply and install these heat only boilers, where the old heat only boiler has broken down.

You have three installation options which you can choose:

1. We can install the same heat only boiler.

2:  We can install a system boiler:
  • by removing the tank from the loft.
  • we save you space in the loft by removing the feed and expansion tank.
3:  We can convert your conventional heating system to a sealed system. For system conversion, we install a combination boiler.

Below you can see a system boilers installation plan:


The heat only boilers also have one hot water storage tank, where stored and heated at the same time. The heat only boiler also has a water tank in the loft.

This tank will supply the water for the cylinder. The hot water cylinder will heat and producing through immersion.

  • There is a separate central heating feed tank (also known as f&e tank) in the loft. This will top up the system through a feed pipe when it needed. For a conventional system, a heat-only boiler is a perfect choice.
  • It is because there is low pressure, the radiators and heating pipes are old. The weak system can not resist the high pressure what a system or a combination boiler will deliver.

Conventional boiler advantages:

  • You have water backup. In case the boiler breaks down you can use the electric immersion heater.
  • If you don’t have an electric immersion heater, we can install this for you!
  • You can use more shower at the same time without any effect on the pressure or temperature.
  • Any new heat only boiler can work with an old conventional system.
  • The conventional heating system is also compatible with solar thermal panels.

The most reliable conventional boiler has a few disadvantages:

  • This takes up a little more space than other types, but this is not a big issue.
  • We need to install a cold water tank in the loft to feed the storage tank.
  • We will install a feed and expansion tank for the heating system for better performance.
  • If you are used all of your hot water from the storage tank, you will have a new one heated up within a few hours. 
  • To avoid the legionella bacteria to grow inside the tank, make sure you always heat the tank above 60°C.
  • You have to deal with some temperature loss on the pipework, but that is not an issue for us, we will insulate them.

You still can’t decide if a heat-only boiler is the right choice? Give us a call to give you more information!
