Bromley Boiler Replacement – What to Know

  • by

There are many factors to consider when replacing a boiler. We will discuss the key factors involved in the replacement of a boiler and assist you in choosing a boiler that is right for you and your heating needs.
Dimensions of the Property

Your property’s size will determine which boiler is best suited for you. System boilers and conventional boilers both use a cylindrical (conventional boilers need a water tank). This makes them more suitable for larger homes. A combi boiler is an excellent choice for smaller properties because it is directly connected to the mains. You should also consider the size and shape of the boiler. Small boilers might not suit small properties, while smaller boilers may be better suited for larger homes.

It is tempting to swap out a conventional boiler or system for a combi boiler, but it may be a wiser choice to keep your existing boiler system (“likefor-like swap”). A combi boiler could be a great way to free up space in your house, but you should also consider the fact that any remnants of an old boiler system, such as a water tank or cylinder, will need to be removed. This will increase the installation cost. A combi boiler may not be the best option if you have old radiators. They might not be able to handle the increased pressure. You may end up paying more if you don’t consider these factors.

There are many bathrooms and showers

System boilers are better suited for homes that have more bathrooms than conventional boilers. Combi boilers can heat hot water simultaneously in multiple bathrooms, but you cannot run two showers or baths at once with combi boilers. A traditional boiler is the best option for large families. The hot water cylinder’s size limits the amount of hot water available. The type of shower you have could also be a factor. A combi boiler replacement can often be incompatible with a power-shower.

The Area has High Water Pressure

When replacing your boiler, it is important to consider the water pressure in your locality. Some boilers are unable to produce enough pressure by themselves. A traditional boiler (also known as a regular or conventional boiler) is the best choice for properties with low water pressure. It can provide high water pressure by using a water tank, which is usually located in the loft. These properties will not find the combi boiler they need.


When replacing your boiler, it is important to take into account the brand of boiler you are using. Different boiler brands offer different levels of energy efficiency. This can impact your gas and water bills. Gas boilers are rated on a scale of A to G. A-rated boilers convert at least 90% of the fuel into heat. A G-rated boiler will be available if your boiler is older than 15 years. These boilers waste 30p per PS1 of gas. This can lead to a significant increase in your annual energy bill of more than PS350. A new boiler’s price will depend on the brand you choose. You should determine what you are able to afford before buying. Trustworthy boiler installation companies should be able offer affordable payment options that allow you to spread out the cost of your boiler replacement Bromley over a longer period.

Type of property

It is important to consider the type of property you own. Older properties that already have a traditional boiler system are more likely to be able to maintain the existing boiler type. Any changes to an existing boiler system are likely to be minimal. You should also think about whether you are planning to extend the property in the future. Radiators will become more frequent in larger rooms, which can put additional strain on the boiler. When choosing the size of your next boiler’s kilowattage, you should keep this in mind. A system or conventional boiler might not be the best option for small houses or apartments where space is limited.

Boiler Flow Rate

The boiler flow rate is the amount of water that can flow through the boiler. It also indicates how fast it can come out from the tap or faucet. The boiler that has the highest flow rate is not always the best. It all depends on the pressure in your mains. If your mains water supply can only handle 10 litres per hour, it is not necessary to buy a replacement boiler with a flow rate of 13.

Boiler flue system

There are many types of flues. This will help you choose the right boiler for you. A horizontal concentric flue design is not the same as one that uses a vertical concentric flue, and vice versa. You need to think about your boiler flue design before you begin looking for a replacement boiler.

Gas Safe Installation

Installation of a boiler can be stressful. A gas safe engineer should conduct your boiler installation. Ask your engineer to show you his identification card. All registered engineers must have one. Online, you can check if their registration number has been valid. Verify that the engineer is qualified. Unqualified engineers could cause irreparable damage to your boiler and invalidate your warranty.
