Choosing the right combi boiler will not just help you save a lot of money but will also ensure you keep your home warm all year round. It would help if you considered all the factors associated with the functionality of the boilers before choosing one. As such, the answer to what is the best combi boiler will differ for every person.
The size of a combi boiler is shown by its capacity, which is measured in kW. Most companies categorize their combi boilers according to their power output, and that should be one of the factors that guide you when you’re searching for a suitable boiler. In most cases, small apartments or flats do well with combi sizes that range between 24 kW to 27 kW.
However, if your home has multiple bathrooms and is larger with 3 or 4 bedrooms, a combi boiler between 28 kW and 34 kW should be enough to cater to our heating needs. A larger sized boiler of 35 kW will serve you well if you have a bigger house. It’s important to note that combi boilers don’t work well when two bathrooms are being used simultaneously. Consider having a system boiler that has an unvented cylinder if you have multiple family members likely to take a shower at the same time. It’s also important to note that the bigger the boiler size, the better the water flow will be.
Combi boilers are generally more efficient, but you should still make sure the one you’re investing in will help you save energy. They should be able to heat your water as well as the rest of your house to ensure you don’t rely on other heating sources. Check the energy ratings to ensure it falls within your regular usage.
Different combi boiler manufacturers issue different warranties, ranging from 5 years to 10 years. The longer the warranty, the more value you’ll get. Longer warranties also show that the manufacturer has faith in their product, which shows you that the combi boiler is a quality investment.
