As a homeowner, installing a new boiler is a major household decision. It is a long-term investment, and needs to cater for both your current and future requirements.
There are a number of factors that you will need to consider, such as how much hot water your family is likely to use, the size of your property, and the number of bathrooms you have.
One of the first factors you’ll need to consider when choosing what size of boiler you need is your hot water demand. For most households that have a single bath and shower, a smaller combi-boiler of 24-30 kW is your best bet. If you have an additional smaller bathroom, a larger 30-35 kW boiler would be better suited to your household. However, if you have a house that regularly has several bathrooms in use at once, a system boiler will be your best option, as this type of boiler pre-heats and stores hot water in a separate cylinder.
Another consideration is the amount of space available in your property. If you have a house with limited storage, a combi-boiler (that provides hot water directly from the mains) will be more space-efficient than having a boiler with a separate hot water tank. For homes with a little more room, a storage combi could be a good alternative. These boilers are similar to combi boilers, but have a small cylinder as part of the boiler framework, meaning that they are able to provide hot water at a quicker rate than a standard combi boiler.
All these types of boilers have their various pros and cons, and it is worth carefully weighing these up before making your investment in your new boiler.
