[A Homeowner's Guide]

Installing a new boiler is not something that homeowners do on a regular basis. It is a major investment for any household, so it is crucial to get it right the first time. Yet, several homeowners often make typical errors during the installation process, resulting in expensive repairs or, even worse, a faulty boiler.

In this guide, we will discuss some of the most common mistakes that homeowners make during a boiler installation and provide tips on how to avoid them.

Common Mistakes to Avoid During a Boiler Installation

Choosing the Wrong Size Boiler

When it comes to boiler installation, choosing the right size boiler is crucial. Many homeowners make the mistake of thinking that a bigger boiler always means better performance, but this is not necessarily true. In fact, choosing a boiler that is the wrong size can result in energy wastage and increased utility bills.

One of the most common mistakes made during a boiler installation is choosing an oversized unit. An oversized boiler may seem like a good idea, as it can quickly and easily heat up your home. However, an oversized boiler will constantly cycle on and off, which wastes energy and puts unnecessary strain on the system.

On the other hand, a boiler that is too small might find it challenging to fulfil your home's heating needs. This means it will need to put in more effort and time to reach the desired temperature, leading to increased utility bills and potentially premature wear and tear on the system.

In fact, choosing the wrong size boiler can be a reason for wasted energy and higher utility bills.

To avoid these issues, it is important to consult with a professional boiler installer who can accurately determine the correct size of boiler for your specific needs. They will consider factors such as the size of your home, the number of occupants, and your heating requirements to ensure you have a properly sized boiler that efficiently meets your heating needs.

Skipping Professional Installation

Another mistake that homeowners make is attempting to install the boiler themselves. While it may seem like a good way to save some money, this can lead to serious problems down the line. Professional installers have the necessary training, experience, and tools for your new boiler installation according to manufacturer specifications.

By skipping professional installation, you risk damaging your new boiler or even putting yourself and your family in danger.

Neglecting the Size of the Environment

The size of your home and the number of people living in it can impact the type and size of boiler you need. Make sure to communicate this information clearly to the installer so they can recommend the right size for your needs.

The size of your home and the number of occupants are key factors in determining the right boiler size for your household.

When a boiler becomes too small, it struggles to meet your heating needs, while one that is too large will lead to wasting energy by constantly cycling on and off.

It's essential to communicate this information clearly with your installer so they can recommend the appropriate size for your specific requirements. This will ensure that your new boiler is the perfect fit to provide efficient and reliable heating in your home.

Also, it's vital to consider any potential changes in your household when determining the size of your boiler. Are you planning to expand your living space? Will there be an increase in occupants? These factors can affect your heating needs and should be taken into account to avoid any future problems with an undersized boiler.

Not Considering the kW Output Power

Regarding boiler installation, it's essential to consider all aspects of the system, including the kW output power. The power of a boiler is a vital factor because it determines the level of heat it can produce. To ensure that your home is adequately heated, it's crucial to work with a professional installer who can recommend the appropriate kW output power based on the size of your home and your heating requirements.

Not Considering Energy Efficiency

Choosing an energy-efficient boiler for your home with the rising energy costs is important. Therefore, think about the energy efficiency rating of the boiler you choose. This will have an impact not only on your heating bills but also on the environment. Opting for a higher efficiency rating saves you money in the long term and reduces your carbon footprint.

However, many homeowners do not consider this during the installation process. It is important to research and compare different boilers to find one that offers the best energy efficiency for your budget.

Not Upgrading Other Heating Components

When installing a new boiler, it is important to consider the condition of other heating components in your home. For example, if your radiators are old and inefficient, they may not work well with a new boiler.

By upgrading these components at the same time as your boiler installation, you can ensure that your entire heating system is working efficiently and effectively.

But Wait! There's More!

Do not Neglect Regular Maintenance and Annual Boiler Service

One of the biggest mistakes homeowners make is neglecting regular maintenance for their boiler. Like any other equipment, boilers require regular upkeep to function properly and efficiently. By ignoring maintenance tasks such as annual servicing, you risk facing costly repairs or even premature failure of your new boiler.

Don't forget also to consider the long-term maintenance and servicing costs of your chosen boiler. While cheaper options may seem more appealing at first, they may end up costing you more in the long run if they require frequent repairs or have a shorter lifespan.

Additionally, think about the energy efficiency rating of the boiler you choose. This will not only have an impact on your utility bills but also the environment. Opting for a higher efficiency rating can save you money in the long run and minimise your carbon footprint.

Lastly, don't hesitate to ask your installer any questions or concerns you may have about the installation process or the chosen boiler. It's important to have clear communication and understanding to ensure a successful installation.

What Boiler Best Suits Your Needs?

With so many options available, choosing the right boiler for your home can be overwhelming. That's where consumer research companies WHICH? can help. They provide unbiased reviews and ratings of boiler brands based on factors such as reliability, customer satisfaction, and efficiency. Consulting with them before making a decision can give you peace of mind that you are investing in a reputable and reliable brand.

However, there are three main types to consider: heat-only boilers, combi boilers, and system boilers.

Heat-only Boiler (Regular Boilers)

  • Also known as conventional or open-vent boilers, these boilers rely on two tanks—the boiler and the hot water storage cylinder. The mains water fills the cold water tank, which then directs water to the hot water cylinder. The heat exchanger inside the boiler warms up the water, distributing it to showers, radiators, and taps.
  • Suitable for larger properties, heat-only boilers are capable of meeting the demands of both heating and numerous taps or shower heads. They are ideal for managing substantial hot water requirements, whereas a combi boiler may struggle to keep up.

Combi Boilers

  • Combining hot water and heating, combi boilers are space-efficient, making them ideal for properties with limited space. They provide hot water on demand, eliminating the need to wait for the water to heat up when using taps.
  • Particularly suitable for small terraced houses, flats, apartments, and bedside installations. However, a drawback is that if the boiler malfunctions, there is no water storage facility, resulting in no hot water or heating until the boiler is repaired.

System Boilers

  • System boilers do not require a header tank in the loft, saving space and avoiding the need for repairs/maintenance associated with tanks. They draw water directly from the mains, and any leaks in the system can be easily identified through a drop in gauge pressure.
  • Unlike heat-only boilers, system boilers do not have storage tanks, expansion tanks, or external expansion vessels. They operate without these additional components and only require a cylinder for hot water storage.

Installing a new boiler is a major investment for any homeowner that shouldn't be taken lightly. When you avoid these common mistakes, you can guarantee a smooth boiler installation, keeping your home warm and cosy all year round. Remember to consult with a professional installer, research energy-efficient options, and keep up with regular maintenance to get the most out of your new boiler.
