What actually is a combi boiler?

As the name “combi” suggests this a combined boiler that provides the heat to your radiators and supplies instantaneous hot water. At present in Ireland these types of boilers are most popular. A combi has a hot water cylinder and a cold water tank. It comes a s an individual stand alone unit this means it is relatively easy to install. Some of the most popular brands would be Baxi and Potterton.

With a combi boiler when you turn on your tap the water is drawn directly from your mains supply. This is then fed through your boiler to be heated, voila hot water! If you use a lot of hot water it is possible to get a storage combi boiler which means you will always have a small back up supply.

The benefits of a combi boiler

  • You won’t have to wait for the cylinder to refill.
  • You have a more or less unlimited, constant hot water supply.
  • Economical and the perfect fit for small houses, apartments or businesses with smaller amounts of water usage.
  • Very compact and takes up very little space as there is no need for a hot water cylinder or a cold water storage tank.
  • All the tap water is potable and suitable for drinking as it comes directly from the mains supply.
  • If the water is heated up to 36 degrees a combi can provide between 17-18 liters of water per minute. This means you can actually run a pretty powerful shower from the bath taps.

The negatives a combi boiler has

  • They aren’t ideal for larger homes and businesses as they only supply full pressure through one water outlet at a time. If many water outlets are used at once this can dramatically reduce pressure.
  • Because the burner needs to warm up to heat the water, there can be a delay in the system providing hot water.
  • Combi boilers can’t supply hot water quickly enough for power showers and they can often seem to run very slowly when filling a bath.
  • There isn’t a back up supply of hot water if you have an issue with the gas of boiler as they do not have an immersion heater.
