Choosing the perfect boiler for your 4-bedroom house can be a daunting task. With so many options available, it’s important to know which type of boiler will provide you with the most efficient and cost-effective heating solution. In this comprehensive guide, we will explore the three main types of boilers – combi, system, and regular – and help you determine the best boiler for your specific needs.
Determining the Ideal Boiler Size for Your 4-Bedroom House
When discussing boiler size, we refer to its output capacity in kilowatts (kW). To estimate the required boiler size for your 4-bedroom house, consider the number of radiators in your home. As a general rule, allow 2kW for each radiator. For instance, a house with 20 radiators would need a boiler with a central heating output of around 40kW.
Keep in mind that this is only an estimate, and consulting a professional installer for expert advice is always recommended.
