What is a Combi Boiler?

Combi Boilers… what are they? If you’ve often heard them but not quite sure what they are then this blog might just help you out

Not all people like change, and changing your boiler and hot water system can sometimes be a big thing to some people. CBQ engineers will always talk you through your options, most of the time a combi boiler is the best option;

  • How water comes through via mains pressure, so not aditional pump or cylinder required (so you can have your loft space back!)

How do combi boilers work?

Combi boilers are one of the most efficient boilers on the market, they remain in a state of standby when there is no demand for heat or hot water. When you turn on a hot water tap, the boiler will activate immediately and produce the heat. This way, there is very little wastage of energy because the boiler does not have to be constantly heating hot water to store in a tank.

  • The small size of a combi boiler means that they can fit into tight or small spaces – so this can work in most houses!
  • Combi boilers tend to have better energy efficiency than conventional boilers, saving you money over time!
  • Combi boilers are quicker to install- this is due to the there being less pipework. Means less disruption and down time in your house!

The cons of a combi boiler are:

  • A combi boiler might not be the best choice if the property has poor mains water pressure, something you can discuss when we give you a quote if a concern.
  • When a combi boiler has a fault or encounters an issue, there is no backup heater system so the property will be without heating and hot water! This is never fun, but your guarantee will hopefully cover you for up to 10 years.
  • A combi boiler can struggle to produce hot water if more than one hot tap is in use at the same time…
