Conventional Boilers

Conventional Boilers

There are different types of boilers, each suited to specific needs and certain styles of homes. We understand that it can be a little confusing, so we’re here to explain the key differences and features in no-nonsense language, plus one of our experienced surveyors will discuss your options when they visit your home.

What is a conventional boiler?

When it comes to conventional boilers (also known as regular, traditional or heat only boilers), they’re usually best suited to homes that have a traditional central heating and hot water system already in place. This will be connected to a separate hot water cylinder, which is often in an airing cupboard, whilst the cold water storage tank that feeds into it will be in the loft. 

There will also be an F&E (feed and expansion) tank that maintains the water level of the central heating system. The result is a large system that takes up a lot of space, but which also offers benefits that other types of boilers don’t.

Can I change to another system?

If you have a conventional boiler and want to upgrade to a system boiler or combi boiler, it may not be possible. If this is the case, it will be because the radiator system is an older variety that isn’t capable of coping with the higher water pressure that newer systems send through them. 

However, ProTech specialises in installing the latest models of conventional boilers, so there’s a very good chance that we can upgrade your system and improve its performance and efficiency. 

What are the pros and cons of a conventional boiler?

To give a clearer comparison of conventional boilers to other types, below are some advantages and disadvantages. 


  • Perfect for properties that have more than one bathroom
  • Constant supply of hot water to multiple taps simultaneously
  • Removes the inconvenience of low water pressure in areas that are generally affected by it
  • By fitting an electrical immersion heater to the hot water cylinder, you’ll have a backup hot water supply in the event of your boiler breaking down


  • Water is heated in advance, so you’ll need to efficiently programme its time controls so that you have it when required
  • The hot water supply can run out and then needs time to refill and heat up
  • The system requires a lot of space, including in the loft and an airing cupboard, which could be freed up by a combi or system boiler
