What is a combination boiler?

If you are on the hunt for a new boiler, you have probably already run into combi boilers. This type of boiler has greatly risen in popularity in recent years, making up about 74% of new boilers in the market.

The name combination boiler comes from the fact that this system is capable of providing heating as well as hot water. It heats cold water from your mains and sends it to your taps on demand. As such, cold and hot water storage tanks are no longer required.

The same hot water is pumped to radiators around your house to heat the room. Without storage of water, combi boilers only provides heating when you need it.

As of April 2005, regulations prescribe that all replacement or new boilers must be condensing boilers. This further increases the already high efficiency rate of combi boilers.

If your property has poor water pressure from your mains, a combi boiler is not the best option. Conventional or system boilers are more suitable for low water pressure mains.

While a combi boiler works well with most showers, it is not powerful enough for a power shower.

You might experience a significant reduction in water flow if multiple water outlets are in use. Combi boilers are less suitable for larger houses with more than 1 bathroom.
