Looking for a new conventional boiler?

Understanding the different boiler and central heating types can be a little confusing. One of our friendly surveyors can explain the various types and help you decide the best solution for your home.

Don’t worry if you don’t know the differences between a conventional boiler and hot water cylinder  as our surveyor will explain this on their visit. In the meantime, you will see below we have put together some helpful information on conventional boilers. This will help you to identify the benefits of replacing your existing gas boiler and the costs associated.

What is a conventional or regular boiler?

Regular boilers (sometimes known as traditional, conventional or heat only boilers) are typically suited to properties that already have a traditional central heating system and hot water system which are linked to a separate hot water cylinder.

If you are thinking of a regular type for your new boiler, you should bear in mind that these need a cold water storage tank in the loft to feed the hot water cylinder, as well as a f&e tank that maintains the water level of the central heating system.

Regular boiler may be the best solution for replacing an existing regular boiler if the property has an older radiator system, as it may not be able to cope with the higher water pressure (pressurised system) that is delivered by system boilers or combi boilers.

Pro's & con's of a conventional boiler

Every household is different, so each home will have their own central heating requirements. There are a number of advantages of having a conventional boiler installed into your home, however they may not be suitable for everyone. Here’s a list which in our opinion details some of the pros and cons of regular boilers:

  • Great for properties with more than one bathroom
  • Constant supply of hot water to multiple taps at the same time
  • A good solution for areas where water pressure is low
  • If you have an electrical immersion heater fitted to the hot water cylinder, you'll have a back-up, just in case your new boiler breaks down.
  • Only heats up water in advance, so effecienctly programming your time controls is important
  • Hot water supply can run out
  • Takes up more area than a combi & system boiler

How much does a new conventional boiler cost to install?

The price of a conventional boiler differs depending on the brand, size, output. The more powerful the boiler, the more it’s likely to cost. Rather than trying to cut costs, you’ll need to choose your new boiler based on the requirements of your home.

Price is likely to be an important factor when choosing your new boiler, so it’s best to work out which type will be the most cost effective with regards to installation, as well as in the future. In some cases, installing the same boiler type (e.g. regular boiler for regular boiler) could be the cheapest option, however this is not always the case, nor is it always the best choice. If you feel like your home could benefit from having another boiler type installed it may be best to switch.
