What types of boilers do we install?

We deal only with the leading boiler brands, including Worcester Bosch, Alpha, Viessmann, Valliant, Glow Worm, Ideal, Baxi, and Zanussi.

We also only install the best boiler types, from combi to electric. The price of your installation in London depends on the make and model you choose as well as the installation company. For your new boiler, you can choose from the following types:

combi boiler london

Combi boiler installations

A combi is the most common type of boiler, being as simple, efficient, and compact as it gets. Short for combination boiler, combis are designed to combine all of the main elements of a traditional boiler into one unit.

They supply a combination of both heating and water and are so compact that they can fit neatly in your cupboard like the Viessmann Vitodens 050-w.

Combi boilers are amongst the most economical options, as you only pay for what you use. It can provide your home with warmth directly, on-demand, and without the need for a tank.

Factors that impact the cost of combi boiler installations include moving the boiler positioning, what floor you’re on, and boiler flue issues. However, with fewer parts, they are generally easier to install than the likes a system boiler. For this reason, they may be the most cost-effective boilers to install, particularly if you live in London.

We can provide combi boiler installations in London starting from £1,840.

System boiler installation

A system boiler is the opposite of a combi boiler. It features two separate components, a boiler and a cylinder, and takes up more space than a combi boiler.

system boiler hot water tank london

The two components are typically split up, with the hot water tank commonly stored in the loft and the water cylinder in the airing cupboard.

Although not as efficient as a combi boiler, a system boiler does have benefits over the likes of a conventional boiler. The latter requires both a hot and cold tank, whereas a system boiler only needs one hot tank.

This tank can store plenty of hot water, meaning you can easily run two taps at once and expect the same volume of hot water from each.

System boilers are typically more expensive to install than combi boilers as both the water cylinder and the tank need to be fitted.

We can fit system boilers easily in all areas of London

Condensing boiler installation

Condensing boilers are a type of boiler in their own right, but you can also get condensing system boilers, condensing combi boilers, and so on. Condensing boilers are 90% energy efficient, as it recycles the heat from the gas it produces and uses it to warm the central heating system.

In other boiler types, this heat energy escapes through the flue, which renders non-condensing boilers only 60% energy efficient. Ensure any installation company you use in London provides you with a condensing boiler!

Q What kind of fuel does your boiler use?

Conventional boiler installation

A conventional boiler – also referred to as a heat-only boiler and a regular boiler – is the oldest boiler type still commonly in use. It consists of two tanks, one for holding cold water and the other for holding hot.

The cold water tank is stored in the loft, which sends water down to the boiler when required. The heat exchanger turns this into hot water, which is then stored in the hot water cylinder.

A regular boiler is recommended for families who need hot water in several places at once. It is also amongst the easiest boiler types to replace.

Our conventional boiler installation starting price is £1,740.

Oil boiler installation

oil boiler london

Oil boilers work almost exactly the same as any other boiler, except gas is swapped for oil. Getting an oil boiler installation is recommended for those who live off the gas grid and require a reliable alternative.

The oil is stored in a tank, which is normally kept outside, and oil is fed to the boiler when hot water is needed. The oil is ignited in the combustion chamber, and the heat produced is used to heat water, which is then sent around your central heating system.

Both the boiler and the oil tank make this option a more expensive one. However, oil boilers are far more durable than other boiler types and can last over 35 years after installation.

Oil boilers in London are expensive to buy new. For example, the Worcester Bosch Greenstar Heatslave II has a starting price of £2,369 and will require an OFTEC registered installer.

electric boiler london

Electric boiler installation

An electric boiler is another good gas alternative appliance. It is far easier to install than gas boilers, as a flue won’t be necessary. This means that the boiler installation cost may be significantly less.

Instead of using gas or other fuel, electricity is used to heat the water in the boiler. Cold water is fed directly to the heating element from the mains water supply, which the boiler can then turn into hot water.

With no gas or fuel burned or wasted, electric boilers are more energy-efficient than combis and other types of boilers.

We sell a range of different electric boilers in London that we can install, starting from the Electric Heating Company’s Comet, priced at £695, to the Thermaflow TH 9/210U, priced at £2,300.

How Long Does It Take to Install a New Boiler?

tools for installation london

If you order a new boiler from us before noon during the winter or 2 pm during the summer, you can get next-day boiler installation anywhere in London.

There are not many boiler providers who can provide such a fast turnaround, especially in London. Our engineers will arrive at your home between 8 am – 10 am.

The length of time it takes to install the new boiler depends on the type of boiler being installed and other labour factors.

For example, to replace an existing combi boiler with another combi, you can expect labour time to be as short as 6 hours. However, if you want to relocate the position of the combi boiler, you can expect this to take up to 2 days to complete.

If you require a boiler conversion to be carried out, you can expect it to take between 1-2 days.

The most lengthy boiler replacement procedure is swapping a back boiler to a combi, which can take between 2-3 days. This takes a while because back boilers are positioned behind your fireplace, making them difficult to remove.

  • The complexity of the job – Boiler replacements are generally cheaper than boiler swaps, as all the wiring and piping will already be in place. However, if you’re swapping over from a conventional to a combi boiler, you can expect labour costs to be significantly higher. This is due to the amount of additional fitting or replacement work that will be required.
  • The boiler type – An electric boiler installation is cheaper to install than a system boiler.
  • Where your boiler is installed -We charge more for boiler relocations, as this costs a lot more in labour time and effort.
  • The number of add-ons – If you are also getting thermostats and filters fitted, you can expect to pay more.
  • The weight of the boiler – The heavier the boiler, the more you’ll have to pay in labour costs. If you’re getting a sizable boiler installed, you’ll likely have to pay for a two-man installation job.
