This model is compact and stylish, taking up little space in your home while tending to your energy needs.

This kind of boiler is highly efficient, which means that you can avoid overspending on fuel to keep your appliance running. However, before opting for the Greenstar i Junior for your home, you should carefully consider your energy consumption requirements.

The Logic Max System is also known for its quiet operation, which means that you will be enjoying your boiler’s benefits without any disruption to the comfort of your home. 

Before choosing the Logic Max System for your home, you should know that this appliance involves a complex installation process. As a result, you might be spending more on installation costs than with another boiler model. You should reach out to a heating engineer to find out whether this Ideal boiler model would be the best option for your home. 

Best cheap conventional boilers under £1,000

As you will see, conventional boilers are typically a more expensive option, as they require additional components to function. In the table below, we selected some of the best cheap conventional boiler options available today based on the quality of their performance and their low cost

Worcester BoschGreenstar Ri Regular2-5 years24 kW£750 – £1,000

When choosing a new conventional boiler for your home, one of the models you should keep an eye on is the Baxi 400 Heat. Baxi boilers are known for their reliability and cost-effectiveness, which also apply to the 400 Heat conventional boiler. 

The Baxi 400 Heat is an A-rated appliance with an efficiency rating of about 89%. While this rating might be lower than other models, the 400 Heat can still tend to the energy needs of small homes very well. What also makes this appliance appealing to homeowners is the fact that it comes with a standard warranty of 5 years for both parts and labour. 

If you are considering the Baxi 400 Heat conventional boiler for your home, you should first carefully think about your energy consumption requirements. While this boiler model is a great choice for smaller homes, it might not be able to attend to the needs of larger households. A heating engineer will be able to help you determine whether the Baxi 400 Heat is the right appliance for your home. 

Cheapest boiler installation

When trying to calculate central heating prices, one of the key factors you will need to consider is the cost of your new boiler installation. Typically, installation costs range anywhere from £500 to £4,000. Whether the exact installation costs for the job on your home will be lower or higher will depend on several factors. 

Installation costs

Firstly, the type of boiler you choose to have fitted will significantly affect your expenses. A combi boiler is usually the cheapest to install, whereas system and conventional boilers have higher installation costs. This is because they require additional elements such as water storage tanks, which take more time and effort to install. 

In addition, the kind of boiler swap you require affects the total installation costs. A like-for-like boiler replacement will cost less than switching to a different boiler type. For example, if your old boiler was a combi but you want your new one to be a system boiler, installing the additional components of this boiler type will involve higher service costs. 

At the same time, the complexity of the installation will affect the service costs a heating engineer will charge you. For instance, if the pipework in your home requires adjustments to accommodate your new boiler, your expenses will be higher when it comes to paying parts and labour.

Another factor to consider is the accessibility of the installation site. To keep your installation costs as low as possible, you will want to ensure that the space where your new boiler will be fitted is cleared. If the installers need to remove any obstacles from the installation site, their job will take longer and you will be spending more on labour costs. 

Finally, the installer you choose to work with significantly impacts the installation costs you will pay. To find the cheapest boiler installation for your home, you will want to compare the service costs of several different installation companies. 

Finding information about prices on your own can be a tedious task that takes up hours of your precious time. Fortunately, you can avoid the hassle and get the process of consulting a heating engineer started in just 1 minute!

What type of boiler is cheapest to run?

Before choosing your cheap boiler, you will also need to consider running costs, as those will determine your yearly heating bills. Some factors to keep in mind when making your calculations are your boiler’s efficiency, the cost of installation, as well as the kind of fuel your appliance runs on.

For a better idea of how much you will spend per year on keeping your boiler running based on the kind of fuel you use, you can consult the overview below: 

Annual boiler running costs per fuel type
