Choosing a boiler is a confusing and frustrating topic for many people.
With climate and the environment being such a hot topic in today’s world, ensuring your boiler is energy efficient is also crucial and could save you money on your energy bills. So, this article will help clarify which type of boiler is considered the most energy-efficient.
A combi boiler is considered one of the most energy-efficient, as they heat water only when you need it. Compared to a regular boiler, a combi doesn’t require a water tank or cylinder, so no excess water is stored.
However, combi boilers aren’t suitable for larger homes, or bigger families as hot water can only be used at one source at one time. In other words, you can’t run hot water from the kitchen tap when someone is in the shower.
These boilers require a hot water cylinder and a cold water tank (normally situated in a loft).
An A-rated regular boiler that condenses is a good option and is more energy-efficient However, regular boilers require water to be heated in advance, and often results in using more heat than you need. This greatly diminishes the energy efficiency of regular boilers.
Despite this fact, regular boilers are still more suitable for bigger households, and homes with more than one bathroom, as hot water can be accessed everywhere simultaneously (unlike combi boilers).
System boilers are similar to regular boilers as they need to heat water in advance, which is stored in a hot water cylinder. However, they don’t require a water tank; therefore, system boilers are more efficient than regular boilers. Also, they’re suitable for larger homes, and they can integrate with solar thermal systems giving them scope to become more energy-efficient.
The main factor to consider is whether the boiler is condensing, and is A-rated for energy. If so, you just need to choose the type that suits your needs. Once your boiler is installed, you should consider how you consume energy, for example, how long your lights are left on. Washing machines and dishwashers consume the most energy, so perhaps using these less frequently will help your home become more energy-efficient.
Furthermore, consider how energy-efficient your appliances are and ensure that TVs, lights, fridges, and freezers have a high energy rating.
These decisions will greatly reduce your energy consumption, drive down your bill and help the environment at the same time.
