If your current boiler is starting to struggle (or worse, has broken down completely) it might be time to consider an upgrade. A modern boiler not only improves the comfort and efficiency of your home, but it can also lower your energy bills and reduce your carbon footprint. At AF Bathroom and Heating, we’ve helped homeowners across Plymouth, Devon, and Cornwall make smart boiler choices based on their home size, lifestyle, and budget. In this guide, we’ll walk you through the different types of boilers, when to replace your old one, and what to consider when choosing a new model.
Why You Might Need a New Boiler
Boilers typically last around 10–15 years, but if yours is over a decade old, it may no longer be performing efficiently. Common signs that you may need a new boiler include rising energy bills, inconsistent heating or hot water, strange noises, frequent breakdowns, or visible leaks. In some cases, parts for older models become hard to source, making repairs expensive and unreliable. Replacing an outdated boiler with a modern, energy-efficient system can not only solve these issues but also bring long-term savings and peace of mind.
Types of Boilers Explained
There are three main types of boilers available in the UK: combi, system, and conventional. Each one has unique advantages depending on your home’s size, water usage, and existing heating setup.
Combi boiler (short for combination) is a space-saving option that heats water directly from the mains whenever you turn on a tap. This means there’s no need for a hot water cylinder or cold water storage tank. Combi boilers are ideal for smaller homes or flats with one bathroom, as they deliver hot water on demand and are highly efficient.
System boilers use a separate hot water cylinder but don’t require a cold water tank in the loft. This setup is great for homes with multiple bathrooms or higher hot water demand, as it allows for simultaneous use across taps and showers.
Conventional boilers, also known as regular or heat-only boilers, require both a hot water cylinder and a cold water tank, often in the loft. They’re best suited for larger homes with traditional heating systems already in place. While less common in new builds, conventional boilers are still a reliable choice in properties with older pipework and radiators.
How to Choose the Right Boiler for Your Home
Selecting the right boiler involves more than just picking the latest model. You’ll need to consider your household’s hot water usage, number of bathrooms, available space, and whether your current system needs upgrading. It’s also wise to think about futureproofing… a boiler that meets today’s needs might not be the right fit if your household grows or your hot water demands increase.
Energy efficiency should also be a top priority. Look for boilers with an A-rating for efficiency, which can significantly reduce energy waste and lower your monthly bills. Modern condensing boilers are designed to recover more heat from exhaust gases, making them up to 90% more efficient than older models.
