Combi vs regular boilers - which is best?
What boiler is best for your home?
When it comes to choosing a new boiler for your home, there are two main options: combi boilers and heat-only boilers. Each type of boiler has its own advantages and disadvantages, and the right choice for you will depend on your individual circumstances and preferences.
We’ll explore the key differences between a combi and heat-only boilers to help you make an informed decision.
Combi Boilers:
Combi boilers, or combination boilers, are a popular choice for many homeowners because they provide hot water on demand without the need for a separate hot water cylinder. They work by heating water directly from the mains supply, which means that you don’t need to wait for a tank to fill up before you can have a shower or bath.
One of the main advantages of a combi boiler is that they are generally more compact and easier to install than heat-only boilers. They are also often more energy-efficient, as they only heat the water that is needed at the time, rather than constantly keeping a tank of water hot.
However, combi boilers do have some disadvantages. Due to the fact that they rely on main pressure to deliver hot water, they may not be suitable for homes with low water pressure. They may also struggle to deliver hot water to multiple taps or showers at the same time.
Heat-Only/regular Boilers:
Heat-only boilers, also known as regular or conventional boilers, are a more traditional type of boiler that requires a separate hot water cylinder and cold-water tank. They work by heating water in the cylinder and then distributing it around the home as needed.
One of the main advantages of a heat-only boiler is that it can deliver hot water to multiple taps or showers at the same time without a drop in pressure. They are also typically more reliable than combi boilers, as they don’t rely on mains pressure to deliver hot water.
However, heat-only boilers do have some disadvantages. They are generally larger and more complex to install than combi boilers, which can make them more expensive. They also tend to be less energy-efficient, as they need to keep a tank of water hot even when it isn’t needed.
In summary, the choice between a combi boiler and a heat-only boiler will depend on your individual circumstances and preferences depending on your home's needs.
If you live in a small home with good mains pressure and only need hot water from one or two taps at a time, a combi boiler may be the best option. If you live in a larger home with multiple bathrooms and lower water pressure, a heat-only boiler may be the better choice.
