Did you know that 60 per cent of your energy consumption comes from running a boiler in your central heating? Yes, while your boiler plays a crucial role in all your heating processes and applications, it can have a huge impact on your energy use and overall cost. 

For this reason, you want to invest in the right boiler and make sure it works efficiently with optimal performance and results. When it’s in good shape and working condition, your boiler can provide your heating needs and help you save up on your energy bills in the long run.

Let’s explore the three primary types of boiler, along with their advantages and disadvantages. Keep on reading to learn more, so you can decide on what’s best suited for your home.

1. Combination boiler

A combination boiler has these two features: a high-efficiency water heater and a central heating boiler combined in a single compact unit. There is a wide range of commercial boilers available in the market in terms of shapes, sizes, and costs.

  • Pros: A combination boiler is compact and easy to store. It doesn’t need to be installed in a loft and is perfect for smaller rooms or spaces. With a combination boiler, there is a less structural change in pipes, so installation is more affordable.
  • Cons: A combi boiler may not be suitable for a big household with plenty of bathrooms. It may be hard to run hot water from two sources all at once.

2. System boiler

A system boiler or sealed system consists of cylinder storage stored in an airing cupboard aimed to provide both central heating and hot water. It directly heats your central heating system and produces hot water in the storage cylinder for use. 

  • Pros: A system boiler is best for larger homes with multiple bathrooms and en-suites. It works for households with several occupants, ensuring a constant supply of hot water. Also, it doesn’t require installation in a loft.
  • Cons: One drawback of a system boiler is waiting for the water to heat up once it runs out. Also, it can be a bit tricky to find space for your cylinder unit.

3. Open vent boiler

An open vent boiler is a regular boiler that is often known as a traditional, conventional, or heat-only boiler. It generally provides central heating and hot water by way of a storage cylinder. The cylinder is housed in the airing cupboard, and the water tank is kept in your loft.

  • Pros: An open vent boiler has a high water flow rate. This boiler type is best for a powerful shower.
  • Cons: The problem with an open vent boiler is that it takes up a lot of room in the average loft. It can be hard to find space to fit the cylinder unit. Also, there’s a waiting period if the hot water runs out.

When it comes to investing in a boiler, you have two routes to take—change your existing one or consider a boiler repair. Investing in a newer, more efficient boiler can help you save on your energy bills every month. On the flip side, it’s a practical solution to get a repair if it’s just a minor problem. 

Furthermore, there are a few things that you can do to ensure the efficiency of your boiler. You can upgrade your heat recovery devices, insulate the hot water cylinders, and invest in chemical inhibitors. Whether it’s a combination boiler, system boiler, or open vent boilers, taking these small-scale measures can make a huge difference.
