When getting a new boiler in London, the cost can differ depending on a few factors, such as the type of boiler, the size of your home, and the complexity of the installation. In general, prices for a new boiler in London usually start from £2,000 and may go up to £5,000 or higher.

Here are some of the things that can change the cost of a replacement boiler:

Type of boiler: There are multiple kinds of boilers available, including combi, system, and conventional. Combi boilers are usually the most budget-friendly option, while system and conventional boilers may be more pricey.

Size of your home: The size of your house will determine the size of boiler you need, and as a result, the cost. Generally speaking, a bigger house requires a larger boiler which costs more.

Complexity of the installation: The sophistication of the installation will affect the price. If you need to set up a fresh gas pipe or adjust your existing heating system, then it will cost more.

Frequently ASked Questions

What is the best combination boiler?

Selecting the perfect combi boiler can be difficult, as it all depends on your own needs and preferences. Fortunately, some of the most popular and highly-rated boilers on the market include the Worcester Bosch 8000, the Viessmann Vitodens 100-W, and the Vaillant Ecotec Plus Combi. Not only are these boilers efficient and reliable, they are also capable of managing your entire heating and hot water needs. Additionally, they come with great features such as smart controls, weather compensation, and quiet operation.

When choosing your ideal combi boiler, be sure to consider your home size, hot water needs, and budget. Talk to a professional heating expert for their advice and to make sure you get the right combi boiler for your home. And always check that the boiler comes with a solid warranty and after-sales support, giving you peace of mind. The best combi boiler is the one that meets your needs and keeps you warm and cosy all year round.

What is the best boiler for a flat or 2 bed house in London?

If you’re snug in a flat or 2 bedroom house, a smaller combi boiler could be ideal. Combis do the job of both your heating and hot water system, making them excellent for saving space in smaller dwellings. A 24-28kW combi boiler should be sufficient! Some of the most popular models in this size range include the Worcester Bosch Greenstar i Junior, Vaillant ecoTEC Plus and Ideal Logic Max.

Take the time to consider your space and hot water needs when selecting your boiler. Consult a heating expert to identify the ideal boiler for your flat or 2 bedroom house. The perfect fit will be a boiler that is efficient, reliable, and compact, ensuring your home stays warm and comfortable.

What is the best boiler for a 3 bed house in London?

If you reside in a 3 bedroom house, it’s likely that you need to purchase a bigger combi boiler that can keep up with your heating and hot water demands. A 28-33kW combi boiler is generally considered suitable for such dwellings, but it is advisable to get professional guidance from an experienced heating specialist. They will assess your unique needs and guide you towards the most suitable size.

The size of your home will determine the power of the boiler you need. Those with larger homes with more bedrooms and bathrooms will likely require a higher output boiler to ensure everything runs as it should.

When making a decision about which boiler to install, consider what features are most important to you. Think about smart controls, energy efficiency and the warranty available. To ensure you make the best choice for your home, it may be wise to seek advice from an experienced heating expert. The best boiler for a 3 bedroom house should keep you cosy and warm throughout the year, as well as meet your needs.

I’ve got a large house in London– what’s the best boiler for me?

Do you live in a large house and need a new boiler? A combi boiler might not be the way to go. Combis supply both heat and hot water, but in some cases, a large house needs more hot water than a combi can provide. That’s where system or conventional boilers come in!

Big households with lots of bathrooms need a reliable boiler that can provide them with enough hot water. A system boiler is an excellent choice because it comes with a separate hot water tank and pump. This means you’ll never run out of hot water. However, if your home requires both heat and hot water, then a conventional boiler would be more suitable.

If you have a larger home, it might be best to go for a system or conventional boiler, as they tend to be more energy efficient and cost-effective than combi boilers. To find the ideal boiler for your home, it’s always a good idea to talk to a professional heating expert. They can evaluate your specific requirements and assist you in selecting the best option.

Combi Boiler Installers London

Learn more about Combi boilers

Homeowners in London can benefit from the installation of a Combi boiler. This type of boiler is renowned for its space-saving qualities and combines both hot water and central heating within one unit. This removes the need for a separate hot water tank.

If you have a single bathroom, Combi boilers are an excellent option since they can only supply hot water to one tap at a time. Before installing a Combi boiler, you should inspect your home’s water mains pressure. If the pressure isn’t up to par, you may need to investigate other possibilities, such as installing a Heat-Only or System boiler with a separate hot water tank, or increasing the mains water pressure with a pump and break tank.

Homeowners in London can enjoy a range of benefits when they install a combi boiler. Not only do they save space, but they are also incredibly energy efficient and simple to maintain. Combi boilers are often a more cost-effective heating option, as they only heat up the water when you need it, leading to lower energy bills. Moreover, combi boilers are incredibly reliable and can last over 10 years with a standard guarantee.

When it comes to installation, Combi boilers are relatively straightforward. They don’t require a separate hot water tank, making installation much easier and quicker than traditional boiler systems. Plus, Combi boilers are compatible with many modern heating controls, such as smart thermostats, so you can easily control the temperature of your home with the touch of a button.

Are you looking for an energy-efficient solution for your home? Then a Combi boiler is definitely worth considering. These boilers are designed to be highly efficient and produce fewer emissions than traditional models, making them a better choice for the environment. So, if you want to reduce your carbon footprint, a Combi boiler is a great choice for any household in London.

London System Boiler Installers

Learn more about System boilers

A system boiler is a type of boiler heating system, used in larger London homes that have multiple bathrooms. Unlike a combi boiler, a system boiler needs a hot water cylinder to store and heat the supply of hot water that is then used to operate taps and showers in the home. This type of boiler is designed to be used in homes that require a greater level of hot water storage capacity, and deliver hot water to multiple taps and bathrooms simultaneously.

If you’re tired of running out of hot water when several people need to shower at the same time, a system boiler is the perfect solution. This type of boiler can supply a steady and reliable stream of hot water to multiple bathrooms at once, without sacrificing pressure or temperature. Unlike other types of boilers, such as combination boilers, system boilers can maintain a consistent high level of hot water pressure, no matter how many bathrooms are in use. So, if you want a hassle-free heating system for your large family home, a system boiler is definitely the way to go.

System boilers may not be the ideal choice if you live in a home with limited space. This is because they require an additional hot water cylinder and associated pipework, which can take up a lot of space. The installation of system boilers is also more complex than other types of boilers, and therefore the installation cost tends to be higher than a combi boiler.

Selecting the right system boiler is crucial for meeting the hot water demands of your home. If you have a large family, multiple bathrooms, or take frequent showers, it’s recommended that you choose a system boiler with a larger cylinder capacity for maximum efficiency.

London Heat only Boiler Installers

Go to our heat-only boilers page

Installing a heat only boiler can be an economical solution for your home’s heating and hot water needs. It is an ideal choice for larger homes as it can provide consistent hot water on demand if coupled with a large hot water cylinder, even if multiple taps or showers are using hot water at the same time. The design of a heat only boiler is quite simple and easy to maintain, making it a great choice for new builds and renovations.

Heat only boilers are also known as regular or open-vent boilers, as they are the more conventional way of heating your home. They are able to operate with a hot water tank on either an open vented or sealed heating system. Plus, they have the added benefit of working even if there is a low mains pressure.

Are you in the market for a new boiler to replace your old conventional one? Consider a heat only boiler for its cost-effectiveness and versatility. With the ability to provide heat for your central heating and hot water for your cylinder, it can also handle multiple taps or showers with ease.

A heat only boiler installation guarantees a steady supply of hot water and central heating for your home. Not to mention, it can work successfully with low mains pressure, which is an added bonus.

Are you on the lookout for a new boiler? A heat only boiler could be the perfect choice for you. Its simple design and easy maintenance requirements make it an excellent option for both new builds and renovations.
