Find a Conventional Boiler for Your Home

What Is a Conventional Boiler?

A conventional boiler is often called a regular or heat-only boiler. Therefore, be aware that they all mean the same so do not get confused if people separate them into different categories: it’s the same! This specific type of boiler is considered as the standard heating system in buildings possessing a central heating process. The water heated up by a conventional boiler is then stored in a separate water cylinder to keep it warm until it is used in the household. Therefore, with this process, you need two water cylinders: one to supply cold water to be heated up and one to store the hot water when it is ready to be supplied to the household.

This specific kind of boiler suits larger homes that need an important hot water and heating supply. It is also more convenient to implement it in big properties as you have more space to install it compared to regular houses. Indeed, as this system requires two water cylinders, you need to be able to store it in your house. Thus, a specific space should be allocated in your house for it if you plan on investing in this kind of boiler. Finally, a Heat-Only boiler can deliver hot water to several taps at the same time due to the amount of water already stored in the cylinder.

How Does It Work?

The cold water which is stocked in the water tank goes to the hot water cylinder and is heated up by the boiler through wires present inside the cylinder. When the water is hot, it is stocked in the hot water cylinder until it is used in the household for heating purpose or just at the tap. It is thanks to a pump that the water is able to circulate throughout the pipes to heat the radiators and therefore your home. The cold water tank has its importance because it moderates the supply of cold water going to be heated up inside the hot water cylinder by the boiler. As said earlier, you can use at the same time taps, shower or bathtubs. However, if all the water is used, it can take some times for the cylinder to reheat the water it contains.

How a Conventional Boiler Works

Pros of Conventional Boilers

  • It perfectly fits your needs if you possess a large property where the water need is more important than in normal houses. Indeed, thanks to the two water tanks, your water supply is higher than the one you could have with another type of boiler such as with a combi boiler.
  • You can use several sources of hot water at the same time without getting it colder. It is therefore perfectly suited if you have more than 2 bathrooms.
  • If you move in into an old property, it is easy to replace the old boiler system with a new conventional boiler as it will require few pipes to be replaced. You will then save time and money during the installation of your new heating system.

Cons of Conventional Boilers

  • This system takes a lot of space. Therefore, if you do not possess a large property, we advise you to invest in a smaller heating system, which is less space-consuming.
  • As said earlier, you have access to a large amount of water. However, this amount is limited by the size of your cylinder. So be sure to invest in the cylinder size that best fits your needs.
  • The pump used to push the hot water into the pipes is independent of the boiler structure and requires additional place.

How Much Does It Cost?

It is recommended to buy a new conventional boiler compared to a second hand one. Indeed, you will benefit from the supplier warranty, its customer service and the installation by a certified professional. This process will in the end save you time and money, justifying the initially higher new boiler costs in the long-run.

As with other boiler types, two main criteria are to be taken into account when choosing a new boiler; thus those factors influencing the boiler price.

First, you need to estimate your hot water and heating needs in order to adjust the power of the desired boiler type. If you have 3 bathrooms and an important property, you will need a more powerful conventional boiler rather than if you have only 2 bathrooms and a smaller home.
However, besides the size of your property, you also need to take into account the quality of the product you want to invest in, its efficiency and reliability. A boiler represents an important investment. You then need to choose it carefully.

According to the type of boiler you choose, it will cost you approximately £400 to £1,500.


What conventional boiler model should I choose and from which brand?

In order to be able to choose the right model that best fits your needs, first try to make an estimation of your heating and hot water needs. According to this estimation, that can be done by a Gas Safe Register engineer, you will know what kind of power output is essential for your home. Thanks to this estimation, you can then consult our page about boiler brands and, if you need any further help, you can contact us by filling in the form on the top of this page and we will provide you with a customised help.

Is the efficiency of a conventional boiler lower than any other type of boiler?

According to the age of your installed boiler, its efficiency will be impacted. Indeed, if you possess a relatively recent boiler, its efficiency will be subsequently higher than a central heating system installed in an old building. A Conventional Boiler differs from other boilers as it is particularly suited for larger homes. Therefore, if you possess a small to medium property, it is better to invest in a condensing boiler or a wood-fired/pellet boiler to save on your energy bills.

Are conventional boilers difficult to install?

If you are already equipped with an old central heating system, it will be pretty easy to replace it with a modern conventional boiler. The installer will only need to replace some pipes so your installation costs will be relatively low. However, if you switch from a condensing boiler to a conventional boiler, your installation costs will be higher as it will require the engineer more work to connect the existing pipes to the new system you wish to install.

Am I eligible for the boiler replacement allowance if I decide to invest in a new conventional boiler?

Among the criteria you need to fulfil in order to be eligible for the Boiler Replacement Allowance, you need to possess an old central heating boiler that is at least 15 years old. Thus, you should definitely apply for this grant if you want to replace it with a new conventional one. However, it needs to be SEDBUK 'A' rated.
