A conventional boiler, or regular boiler, is the kind that heats water in a tank rather than supplying on demand hot water. This is fed from a cold water tank that is usually kept in the loft. Many people prefer to have this kind of system if they have multiple bathrooms that may be in use at the same time, as this system does not have the problems of getting suddenly very hot or very cold water that you can get from multiple taps on a combi boiler system. It provides central heating efficiently too.

The installation process is much the same for the boiler itself, although you may also choose to have a back boiler, which does not take up space in the kitchen. These are often installed into a chimney breast behind a gas fire. Obviously there is more work to install the boiler and it is not as accessible for maintenance, but it does mean that you do not lose space elsewhere.

Getting your conventional boiler put in

The amount of work needed to install your conventional boiler will depend on whether this an entirely new installation or if it is to replace an existing boiler. If this is a new installation then there will be significant preparation work needed to install the boiler and the feed tank (along with an expansion tank to keep the system safe and efficient) as well as a hot water tank to store the heated water.

There could also be extensive pipework to be laid and fitted. Once this preparation work is done, or if you are simply replacing your old boiler, the heating engineer will fit the boiler and attach it to the gas, central heating and water supply before testing. The engineer should explain things like the timer, thermostat and how to work the immersion heater or other functions to provide extra hot water. This job will take most of the day to complete and can take even longer in some circumstances.

Pros and cons of a conventional or regular boiler

  • You can get hot water from multiple taps at the same time.
  • Ideal if you have multiple bathrooms.
  • The hot water can run out and you’ll have to wait for it to reheat.
  • You need to find room for the cylinder and the tank.
