5 Benefits of Choosing a Combination Boiler

1. Combination boilers are generally cheaper.

Because of the simplicity of combination boilers, which take water from the mains and heat it for showers and taps, installing them will typically be cheaper than alternatives.

Plus, you won’t have to pay for a hot water cylinder or a cold water tank, which you would require with a regular boiler or with certain system boilers.

As these boilers combine both your central heating and hot water, it’s a useful all-in-one solution for your home.

2. Get your hot water instantly.

One of the disadvantages of choosing a system boiler is that your boiler has to utilise a hot water cylinder to heat your water. Once it runs out, you have to wait for more water to be heated up.

On the other hand, a combination boiler takes its water from the mains, which means you can get hot water instantly.

You also won’t run out of hot water, and your cold water will be safe to drink because it’s taken directly from the mains.

3. Combination boilers have a compact size.

Many combination boilers will give you slim and sleek designs, which often means that they can be installed in a small space, such as your kitchen cupboard.

This means you won’t have to sacrifice any loft space for a cold water tank or hot water cylinder.

4. They are easier to maintain and service.

Making sure that you make your boiler last as long as possible is an essential part of keeping your home safe and warm.

Because combination boilers are a popular choice, it means that most engineers will know how to service and maintain your boiler.

5. Combination boilers are efficient.

Combination boilers are a more efficient choice for many households because they are less likely to suffer from pressure issues, as water is taken from the mains. Also, because water isn’t stored in a tank, it won’t be at risk for rust or any particulates.
