The cost of a new boiler in London can vary depending on several factors, such as the type of boiler, the size of your home, and the complexity of the installation. Generally, prices for a new boiler in London range from about £2,000 to £5,000 or more.

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 complexity of installation can have a bearing on the cost. For instance, if you need to put in a new gas pipe or alter your pre-existing heating system, then you’ll end up paying more.

questions & answers

What’s the best combi boiler?

Choosing the best combi boiler can be a bit tricky, since it all depends on your own needs and preferences. But don’t worry, some of the most popular and well-loved boilers on the market include the Worcester Bosch 8000, the Viessmann Vitodens 100-W, and the Vaillant Ecotec Plus Combi. These boilers are known for being efficient, reliable, and able to handle all your heating and hot water needs. Plus, they come with cool features like smart controls, weather compensation, and quiet operation.

Selecting the right combi boiler? Start by thinking about your home size, hot water needs, and budget. Don’t forget to consult a professional heating expert to make sure you get the best combi boiler for your home. And make sure to choose a boiler with a good warranty and after-sales support, so you have peace of mind knowing you’re in safe hands. The best combi boiler is the one that meets your needs and keeps you warm and comfortable.

What’s the best boiler for a flat or 2 bedroom house in London?

If you’re occupying a flat or two-bedroom home, you could benefit from a compact combi boiler. These boilers act as both a heating and hot water system, making them an ideal choice for smaller properties. A 24-28kW combi boiler should do the trick! Some of the most popular models in this size include the Worcester Bosch Greenstar i Junior, Vaillant ecoTEC Plus and Ideal Logic Max.

When looking for a boiler for a flat or 2 bedroom house, make sure to consider how much space you have and how much hot water you need. Talk to a heating expert to help you find a model that is reliable, efficient, and compact, ensuring your home remains cozy and comfortable.

What’s the best boiler for a 3 bedroom house in London?

Are you the proud owner of a 3 bedroom property? You will likely require a combi boiler with additional power to meet your hot water and heating needs. Usually, a 28-33kW combi boiler should be sufficient for this size of house, however it is recommended that you consult with an expert in heating to identify your individual requirements and assist you in finding the optimal size for your home.

To ensure your home is heated and supplied with hot water, it’s important to have a boiler that can cope with the demand. A bigger household with more bedrooms and bathrooms will require a higher output model to keep it running correctly.

When buying a boiler, don’t forget to consider the features that matter most to you – such as smart controls, energy efficiency and warranty cover. If unsure, get in touch with an expert in heating who can guide you towards finding the perfect fit for your home. The most suitable boiler for a 3 bedroom house is one that meets your needs and keeps you comfortable all year round.

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

If you have a big house and need a new boiler, we’ve got you covered! Combi boilers that provide both heat and hot water may not be the best option for larger homes. If you need more hot water, then system or conventional boilers are the way to go!

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.

System and conventional boilers are often more energy-efficient and cost-effective than combi boilers for larger homes. To find the right boiler for your home, it’s always wise to seek the advice of a professional heating expert. They can assess your individual needs and help you select the most suitable option.

Combi Boiler Installers London

Go to our Combi boilers page

Combi boilers are a great choice for London households as they are a space-saving option. Combination boilers combine both hot water and central heating in one unit, eliminating the need for a separate hot water tank.

Combi boilers are perfect for households with one bathroom and no chance of two taps being used at the same time. Prior to installation, it is important to check the water mains pressure of your home. If the pressure is inadequate, you could consider alternatives like a Heat-Only or System boiler with a separate hot water cylinder, or a pump and break tank to boost the mains water pressure.

Heating your home in London can be expensive, but it doesn’t have to be. Combi boilers are an excellent heating option that can save you money on energy bills. These boilers are energy-efficient, low maintenance, and compact, making them a popular choice for many homeowners. Combi boilers heat water only when needed, which means you won’t waste energy heating up water you don’t use. And with most combi boilers having guarantees of up to 10 years, you can trust in their reliability and durability.

Installing a Combi boiler is a hassle-free process that can be completed quickly. No separate hot water tank is required, making it easier than traditional systems. Combi boilers can also be integrated with modern heating controls like smart thermostats, so you can manage your home’s temperature with ease.

Thinking of making your home in London greener? Combi boilers are a great option. They’re designed to be highly efficient, meaning they have lower emissions than traditional boilers. With a Combi boiler, you can reduce your carbon footprint and help the environment.

London System Boiler Installers

Find out more about System boilers

A system boiler is a popular heating system for larger homes located in London that have multiple bathrooms. This type of boiler requires a hot water cylinder to store and heat the supply of hot water used for taps and showers in the home. It is designed to deliver hot water to multiple taps and bathrooms simultaneously, making it perfect for homes that require a greater level of hot water storage capacity.

If you have a large family or your home has multiple bathrooms, a system boiler is the best option for you. Unlike other boiler types, such as combination boilers, system boilers are designed to sustain and maintain a high level of hot water pressure regardless of the hot water demand from multiple bathrooms. This ensures your family always has a plentiful supply of hot water.

System boilers can occupy a large amount of space due to the hot water cylinder and associated pipework that needs to be installed. If you have a home with limited space, then this type of boiler may not be suitable for you. Furthermore, the complexity of installation for a system boiler is greater than other types of boilers, so the installation cost will be higher than if you were to install a combi boiler.

When it comes to selecting a system boiler, it’s important to choose one that is the right size and power for your home’s hot water needs. If you have a large family or multiple bathrooms, it’s recommended that you opt for a system boiler with a larger cylinder capacity for optimal performance.

Heat only Boiler Installers London

Find out more about heat-only boilers

For those seeking a budget-friendly and reliable heating and hot water solution, a heat only boiler is worth considering. It’s particularly suitable for larger homes, as it can deliver a steady stream of hot water even when multiple taps or showers are in use. Additionally, the uncomplicated design of a heat only boiler makes it easy to maintain, which is why it’s a top choice for new builds and home 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.

If you’re in the market for a new boiler to replace your old conventional one, a heat only boiler is a wise investment. This option offers both cost-effectiveness and practicality, providing heat for your central heating and hot water for your cylinder while being able to handle multiple taps or showers with ease.

By getting a heat only boiler installed in your property, you can be sure of a dependable source of hot water and central heating. Not to mention, the system can be relied upon to work even with a low mains pressure.

Replacing an old boiler can be daunting, but a heat only boiler is a great choice for those in need of a new one. With a straightforward design and simple maintenance requirements, this type of boiler is perfect for new builds and renovations alike.
