Boiler Installation and Replacement: FAQs and Everything You Need to Know

What are the types of boilers?

There are three types of boilers: system, combination or combi, and regular. System boilers usually get water from a storage cylinder and are perfect for larger homes with multiple bathrooms. Combination or combi boilers are ideal for smaller homes with just one bathroom, as they provide hot water directly from the mains. Lastly, regular boilers are typically found in older homes, and they require a separate hot water storage tank and a cold water storage tank.

What size boiler do I need?

The size of the boiler you require depends on the size of your home, the number of rooms you have, and the amount of hot water you use. Boiler sizes can range from 24kW to 42kW. To accurately size your boiler, you can consult with a heating engineer who can assess your needs and determine the appropriate size. Looking to dive even deeper into the topic?

How much does a boiler replacement cost?

The cost of a boiler replacement can range from $2,500 to $7,500 depending on the type of boiler you require and your location. Additional costs may include labor, installation, and removal of the old boiler. It’s important to obtain multiple quotes from different heating engineers and choose the one that best fits your budget and requirements.

What should I consider when choosing a new boiler?

When choosing a new boiler, there are several factors to consider. You should consider the size of your home, the hot water demand, the energy efficiency rating of the boiler, and your budget. You should also consider the type of fuel you want to use, such as gas or oil. Additionally, you should think about warranties and ongoing maintenance costs.

How long does a boiler installation take?

The installation of a new boiler can typically take anywhere from 1 to 3 days, depending on the complexity of the installation and the type of boiler required. The installation may also take longer if additional work is needed, such as installing a new hot water cylinder or upgrading your heating system.

What should I do if my boiler breaks down?

If your boiler breaks down, you should contact a heating engineer immediately. They can assess the issue and determine the best course of action, whether that be repairing the boiler or installing a new one. If you have a warranty or boiler cover, you should also contact your provider to see if the repair or replacement is covered under the policy.

How often should I service my boiler?

A boiler should be serviced annually to ensure that it is working efficiently and safely. Regular servicing can help prevent breakdowns and prolong the lifespan of the boiler. During a boiler service, a heating engineer will check for any faults or issues, clean the boiler, and perform any necessary repairs or maintenance.

What is the lifespan of a boiler?

The lifespan of a boiler can vary depending on several factors, including the type of boiler, how often it is used, and how well it is maintained. Generally, a boiler can last anywhere from 10 to 15 years. Regular servicing and maintenance can help prolong the life of your boiler.


One of the latest innovations in the boiler industry is the adoption of smart technology. Many manufacturers have started producing smart boilers that can be controlled by a smartphone app. This allows homeowners to monitor their heating and hot water usage, set schedules, and adjust temperature settings from their mobile device. Smart boilers can also notify homeowners if there is an issue or if maintenance is required, making them more convenient and energy-efficient.

Another innovation in boiler technology is the development of condensing boilers. These boilers are designed to be more energy-efficient, using the heat from exhaust gases to preheat the water in the boiler. This results in less wasted energy and reduced energy bills. Condensing boilers can also be compatible with solar thermal panels, further reducing energy consumption and costs.
