Why Buy a New Boiler?

Boilers are an essential part of any home, providing heating and hot water for your daily needs. However, like any mechanical system, boilers can experience faults and failures, and may eventually need to be replaced. Buying a new boiler can be a significant investment, but there are several good reasons to consider doing so.


  • Faults and Failures

    One of the most common reasons to buy a new boiler is due to faults and failures. As boilers age, they become more prone to breakdowns, and the cost of repairs can quickly add up. A faulty boiler can also be dangerous, as it can lead to gas leaks or carbon monoxide poisoning. If your boiler is showing signs of wear and tear, such as leaks, strange noises, or a drop in pressure, it may be time to consider replacing it.


  • Heating and Hot Water Problems

    If you’re experiencing problems with your heating and hot water, it could be a sign that your boiler is not working efficiently. For example, if your radiators are not getting hot, it could be due to a blockage or a faulty pump. If you’re not getting hot water, it could be due to a faulty diverter valve or a broken thermostat. In some cases, these issues can be resolved with a repair, but in others, a replacement boiler may be necessary.


  • Energy Efficiency

    Another reason to consider buying a new boiler is to improve your home’s energy efficiency. Modern boilers are much more efficient than older models, and can help you save money on your energy bills. For example, a condensing boiler is designed to recover heat that is normally lost through the flue, and can be up to 30% more efficient than a non-condensing boiler. A new boiler can also help you reduce your carbon footprint by producing fewer emissions.


  • It’s Beyond Economical Repair (BER)

    In some cases, a boiler may be beyond economical repair, which means that the cost of repairs would be more than the cost of a new boiler. This can happen if your boiler is very old or if it has been poorly maintained. If your boiler is BER, it’s important to replace it as soon as possible, as it could be costing you more money in the long run.

  • Boiler Relocation

    If you’re renovating your home or making significant changes to your heating system, you may need to relocate your boiler. For example, if you’re converting your loft into a bedroom, you may need to move your boiler to make space. Relocating a boiler can be a complex process, and it’s important to work with a qualified heating engineer to ensure that the work is done safely and efficiently.


  • Boiler System Does Not Satisfy Current Usage

    If your current boiler system is not able to meet your current heating and hot water needs, it may be time to upgrade. For example, if you’ve added an extension to your home, you may need a larger boiler to heat the additional space. Or if you’re experiencing low water pressure or inconsistent temperatures, it may be a sign that your boiler is struggling to keep up with demand. Upgrading to a new boiler that is better suited to your needs can help you ensure that your home is warm and comfortable all year round.


In conclusion, there are many good reasons to consider buying a new boiler, from faults and failures to energy efficiency and changing needs. If you’re unsure whether it’s time to replace your boiler, it’s a good idea to speak to a qualified heating engineer who can assess your current system and advise you on the best course of action.

Choosing The Right Boiler

Choosing the right boiler for your home is an important decision. With so many different types of boilers and installation options available, it can be difficult to know where to start. In this article, we'll explore the three main types of boilers - conventional, system, and combi - as well as the different installation options available, including wall-mounted, floor-standing, and back boilers.

  • What Type of Boiler Should I Choose?

    The type of boiler you choose will depend on several factors, including the size of your home, your hot water usage, and your budget. Let's take a closer look at the three main types of boilers:


  • Conventional Boilers

    Conventional boilers, also known as heat-only or regular boilers, are a traditional type of boiler that are best suited to larger homes with multiple bathrooms. They work by heating water and storing it in a hot water cylinder, which is usually located in an airing cupboard. When you turn on a hot water tap, the water is pulled from the cylinder and delivered to the tap.

    One of the main benefits of a conventional boiler is that it can provide hot water to multiple taps at the same time without losing pressure. However, they do require more space than other types of boilers due to the need for a hot water cylinder and a separate cold water tank. This can make them more expensive to install, particularly if you don't already have the necessary infrastructure in place.


  • System Boilers

    System boilers, also known as sealed system boilers, are a type of boiler that works in a similar way to conventional boilers but without the need for a separate cold water tank. Instead, the system boiler incorporates a built-in expansion vessel and circulation pump, which means that they can be installed in homes where space is at a premium.

    Like conventional boilers, system boilers can provide hot water to multiple taps at the same time, but they are more efficient as they don't lose heat through a cold water tank. They are also easier to install than conventional boilers as they require less pipework and have a smaller footprint. However, they do still require a hot water cylinder, which can take up valuable space.


  • Combi Boilers

    Combi boilers, also known as combination boilers, are a popular type of boiler in the UK as they don't require a hot water cylinder or cold water tank. Instead, they heat water on demand as it passes through the boiler, which means that they are more energy-efficient than conventional or system boilers.

    Combi boilers are ideal for smaller homes or apartments where space is at a premium, as they don't require any additional storage space. They are also the cheapest type of boiler to install, as they require less pipework and only need to be connected to a gas supply and a water supply. However, they can struggle to provide hot water to multiple taps at the same time, and their flow rate can be affected by low water pressure.


Types of Boiler Installation

In addition to choosing the right type of boiler for your home, you also need to decide on the best installation option. Here are the three main types of boiler installation:


  • Wall-Mounted Boilers

    Wall-mounted boilers, also known as wall-hung boilers or wall-mounted gas boilers, are a popular choice for small homes and apartments as they don't take up any floor space. They are usually installed on an external wall, and the flue runs straight out of the wall, which means that they are less obtrusive than other types of boilers.

    Wall-mounted boilers can be either conventional, system, or combi, depending on your needs. However, they can be more expensive to install than floor-standing boilers, particularly if you need to install additional pipework.


  • Floor-standing boilers

    Floor-standing boilers are a type of boiler that are designed to sit on the floor, rather than being wall-mounted. They are usually larger and more powerful than wall-mounted boilers, and are often used in commercial properties or larger homes with high hot water demand.

    One of the main advantages of floor-standing boilers is their high output capacity, which means that they can supply large volumes of hot water to multiple outlets at the same time. They are also very durable and reliable, with a long lifespan and low maintenance requirements.

    Floor-standing boilers can be either conventional or system boilers, and are often used in conjunction with a hot water cylinder to provide an efficient and reliable source of hot water. However, they do require a lot of space, which can make them unsuitable for smaller homes or properties with limited space.


  • Back Boilers

    Back boilers are a type of boiler that were popular in the past, but are now less commonly used due to their inefficiency and high running costs. They are a type of conventional boiler that are designed to be fitted into a fireplace, with the flue running up the chimney.

    One of the main benefits of back boilers is their low profile, as they are hidden from view and don't take up any floor space. However, they are very inefficient, with a low energy efficiency rating and high running costs. They are also difficult to repair or replace, as they are often built into the fabric of the property. In 2005 Building laws changed requiring all new boilers to that were fitted to be high efficiency condencing boilers, and so the back boiler came to an end.


In conclusion, choosing the right type of boiler and installation option for your home is an important decision. It is essential to consider factors such as the size of your home, your hot water usage, and your budget when making your decision. Conventional boilers, system boilers, and combi boilers all have their advantages and disadvantages, and the installation option you choose will depend on your individual needs and preferences. Whether you opt for a wall-mounted, floor-standing, it is important to choose a boiler that is efficient, reliable, and easy to maintain, in order to ensure that you have a constant supply of hot water and heating for many years to come.
