About boiler repair, boiler installation & boiler replacement London

Selecting the best boiler for your boiler installation in London is not always easy, with Combi the most popular option, a system that combines a water heater and central heating system in one package.This kind of boiler installation in your London home does require an external tank but with that, it only stores hot water, while the heating is carried out by the boiler itself. 

Another type of boiler installation that London customers have the option of is a standard boiler. These boilers need hot and cold water tanks and are often preferable for  older homes with existing heating and storage systems.

In most cases, we expect a new boiler installation in London properties to be needed after 10 to 15 years, the average lifespan for a boiler, with some lasting longer, some less.

Our boiler installation experts in London are on hand to advise you about the right time for this.

Boiler Servicing, Maintenance Tips
by best Boiler Replacement Company London

Get the boiler
serviced every year

Check the
Boiler Pressure

Our boiler servicing in London includes many checks, one of which is checking that the pressure is at the right level, ensuring that your system is circulating hot water around the pipes and radiators in your home . Checking the pressure gauge will allow our boiler servicing engineers in London to the correct level according to the manufacturer’s user instructions, usually between 1 and 2 bar.

Bleed the radiators
Every Year

As our boiler servicing experts in London remind customers all the time, bleeding radiators can help clear the pockets of air that prevent the radiator from heating up fully. This action does not require a boiler servicing expert to visit your Lonodn home, as you can release this air by bleeding the radiators.

Balance the

With many boiler installations in London homes the radiators which are furthest away from the boiler are cooler than those near the boiler, which is where balancing comes in. Not as simple as the bleeding process, balancing radiators can be part of boiler servicing in London homes and can help the system to heat more evenly throughout the home.

Check for
Radiator Problems

As our boiler servicing experts in London know all too well, radiators getting hot at the top but remaining cold at the bottom is a common issue. This is often due to debris and dirt amassing in your boiler system over time, before settling at the bottom of the radiator. A regular boiler servicing in your London property could avoid this, as well as the more expensive energy bills that are a result of leaving this unchecked.

Never try to Repair a Boiler Yourself

When it comes to boiler repair and boiler servicing in London it is always better to get a professional engineer to do the work. If not handled properly, or without professional knowledge, gas pipes and appliances can be extremely dangerous and could cause fires, explosions or carbon monoxide poisoning. For all your boiler servicing and boiler installation needs in London, call in our professionals.

Does water quality affect my choice of boiler installation & replacement in London?

When it comes to boiler installation projects, the quality of your water can make a difference. When you have checked the quality of the water you receive in your home, you can determine what is best for you in terms of your boiler installation.

Water in the UK varies in terms of whether it is hard or soft, with the scale being quite variable from country to city areas. Most cities have harder water, meaning boiler installation in London should be based on that level of water quality.

Our boiler installation teams are used to working with hard water preferable systems, but with a wide choice of boilers, getting a boiler installation is not difficult. Certain boilers are preferable for hard water areas, so asking your boiler installation engineer in London to advise on these issues is important.

Ultimately, the boiler installation choice is more down to cost and efficiency than it is to the water quality.
