Compare Johnson and Starley Boiler Reviews


Since 1922, Johnson and Starley has been an icon of comfort in the UK domestic heating and ventilation market. The company was started in Blackpool by Mr Johnson and Mr Starley with a small garage.

Over the years, the company has worked tirelessly to achieve the vision the pioneering fathers had of the brand. As the years passed, the manufacturer grew and had major advancements. The brand has been known for its flair in terms of innovation and ability to create high energy efficiency boilers.

Most recently, the company has had a knack for building boilers aimed at addressing condensation problems effectively and efficiently. This is one of the reasons why the company has been receiving a lot of limelight in the recent past.

Johnson and Starley features a full range of boilers which include combi, system and regular boilers in different sizes and outputs to suit the needs of different homes.

Typical Prices for Johnson and Starley Boilers

Johnson and Starley is keen on ensuring boiler safety and the best performance of their boilers. To guarantee this, the boilers are not sold directly to the client but through a team of trained and qualified installers. This ensures that the boilers are correctly installed and are safe for use.

While Johnson and Starley Boilers promise a premium experience, the price tag is quite reasonable. The company manufactures most of its parts and components in-house, which allows them to keep a tight grip on the cost of their boilers. A Johnson and Starley boiler will cost you anywhere between £700 and £1,200 depending on the type and size of the boiler.

Other than the cost of buying the boiler, you will also need to consider the cost of installation, which is also significant. However, unlike boiler prices, the boiler installation cost is not easy to estimate. You need to consider a variety of factors like where the boiler is being installed if it’s a first-time installation or a replacement as well as your location.

Because the boiler installation cost is vital for your budgeting, Compare the Boiler Market can get up to three qualified boiler installers in your area to send you comprehensive and accurate boiler installation quotes. These will help you get an idea of the total cost of getting the boiler up and running.

Even though boilers are essential for the comfort of your home, the cost of installing one is significant. That’s why there are boiler installation companies that offer boiler financing that allows you to get your boiler now and pay for it in small and manageable payments over an agreed period.

Why Choose a Johnson and Starley boiler?

The boiler market is extremely competitive. To stay relevant, each boiler brand has to choose an aspect that they focus on to make their boilers more appealing to homeowners. Johnson and Starley boilers are no different. Certain factors make these boilers such a catch to those who buy them.

Understanding these factors can go along way in ensuring you get a good quality boiler for the most competitive price possible. Considering that Johnson and Starley have been around for close to 100 years, it’s evident they not only understand what boilers are about but also what their clients are looking for.

Each year, Johnson and Starley runs a survey where more 8,000 members participate. This keeps the brand on toes on what the market is looking for and different ways that they can improve their products.

As a result, Johnson and Starley has improved its range of condensing boilers to make the condensation process more efficient. This ensures the boilers are not only safer but more energy efficient.

Benefits of Johnson and Starley Boilers


One of the greatest benefits of using Johnson and Starley boilers is the extended warranties. While other boiler brands offer up to 5 years of warranty, Johnson and Starley offers up to 8 years. This is highly commendable to ensure you have the best experience and peace of mind when purchasing the boiler. The warranty covers both parts and labour.

Built-in frost protection

With the cold weather outside, one of the challenges that condensing boilers face is blockages because of frozen condensate pipes. This can cause the boiler to fail. To prevent this, Johnson and Starley boilers have built-in frost protection that ensures you get the best performance out of the boiler even when the weather is not favourable.

Flexible flue system

Johnson and Starley boilers have a vertical or horizontal flue system. This allows for multiple installation positions for the boiler. The flexible flue system also means the boiler is easier to install and could save you money on the boiler installation cost.


Johnson and Starley has close to a century of experience designing and manufacturing boilers. This, paired with their dedication to understanding consumer needs and wants, ensures that they can build effective and long-lasting boilers. This is evidenced by the extended warranties offered with all Johnson and Starley boilers.

Customer-based approach

Every year, Johnson and Starley conducts a survey. Over 8,000 consumers of their products participate in the survey. This allows them to identify areas that need improvement both in their service delivery and product line. With such an approach, the manufacturer can provide better boilers that not only appeal to the buyers but also solve their problems and needs.

Johnson and Starley Boiler Warranty

Johnson and Starley boilers are built to last. Even though there’s little to no chance that you will run into any problems, it’s always good to have a warranty backing your boiler in case of unexpected breakdowns.

Standard Boiler Warranty

Standard Johnson and Starley boiler warranty is 2 years. However, some models like the Quan Tex HR 28c Combi boiler come with a warranty of up to 5 years. Other models come with up to 8 years of warranty.

What’s Covered by the Warranty?

As long as the warranty is active, your boiler will be covered for faults caused by faulty parts or poor workmanship in the manufacturing process. In the event that your boiler fails, Johnson and Starley will repair or replace the boiler free of charge. In some cases, Johnson and Starley can also authorise the repair work to be completed on their behalf. However, this is only done in writing from the boiler company.

Compare Our Range of Boilers

In the many years that Johnson and Starley have been in the market, they have come up with a variety of boiler solutions for different homes and different needs.

Each of their boilers is a product of careful consideration of the needs and challenges that different consumers face. Since one boiler cannot solve all the problems, the manufacturer has come up with a variety of different types of boilers aimed at addressing the various challenges.

Johnson and Starley Combi Range

Combi boilers are best suited for homes that are struggling with limited space but need hot water. Combis don’t require hot water cylinders or cold water storage. Since the boiler doesn’t require all these additional parts, it saves up on space.

Combi boilers provide hot water on demand. Even without the water cylinders, the boiler produces enough hot water for a small home. The boiler has everything in one unit, which also makes installation relatively easier and of course more affordable.

If you’re considering getting a combi boiler from Johnson and Starley, there are a variety of options you can choose from. The Johnson and Starley combi boilers come in different outputs and efficiency to suit different sizes of homes with varying demands for hot water.

Johnson and Starley combi boiler range includes:

  • Johnson and Starley QuanTec HR 28c Combi
  • Johnson and Starley QuanTec 24c Combi
  • Johnson and Starley QuanTec 30c Combi

Benefits of a Combi Boiler

  • Combi boilers heat water on demand which reduces heat loss and improves energy efficiency.
  • The boiler has everything in one unit, making it easier to install. It also takes up less space in the house.
  • The boiler doesn’t need tanks which means it doesn’t require a lot of pipework during installation.

Johnson and Starley System Boilers

Larger homes with loft space and high demand for hot water can do better with a system boiler. To keep up with the high demand, system boilers are fitted with hot water cylinders that are automatically topped up each time you use the water.

Because of the hot water cylinder, system boilers require additional space in the loft for the tanks to be installed. The boiler also needs more pipework compared to a combi boiler. However, given the convenience that comes with this type of boiler, it is safe to say that the additional installation work and space are worth it.

For system boilers, there’s the Johnson and Starley QuanTex 24s System boiler rated 24kW. At the moment, the manufacturer does not have any other models of the system boiler.

Benefits of a Johnson and Starley System Boiler

  • System boilers are the most adaptable. They can be used in different households with plenty of success.
  • A system boiler balances between efficiency and conserving space. It is small enough to be installed in a kitchen cupboard while the tanks are installed in the loft and big enough to supply a home with multiple bathrooms with hot water.
  • The hot water cylinders of the boilers are always topped up, so you never have to worry about running out of hot water.

Johnson and Starley Regular Boilers

For homes with old pipework or in areas where water pressure is a concern, regular boilers are the best. Even though this type of boiler requires extensive installation work because it has cold and hot water storage tanks, it’s still effective, particularly when it comes to providing vast amounts of hot water.

This is why regular boilers have remained relevant even though the interest is gradually dwindling because of the higher efficiencies of system and combi boilers.

Purchasing a regular boiler can save you money if you’re looking to replace a similar type of boiler and pipework is still in good condition.

In case you’re interested in purchasing a regular boiler, Johnson and Starley has a few options available which include:

  • Johnson and Starley Quantec 24r Regular boiler
  • Johnson and Starley QuanTex 16kW Regular Gas boiler

Benefits of a Johnson and Starley Regular Boiler

  • Regular boilers are ideal if you live in a place with low water pressure.
  • The boilers come in different output sizes to suit the needs of different homes.
  • You don’t have to worry about the supply of hot water with a regular boiler. The boiler is capable of producing plenty of hot water for the entire household.

Johnson and Starley Boilers Problems and Common Fault Codes

Johnson and Starley boilers are built to provide you with long-term service. However, it’s always advisable to know as much as possible about your new boiler and prepare for some of the most common problems. Should anything happen, you have all the information you need, and you can quickly mitigate the problem.

No heating or hot water

This problem is often caused by a broken diaphragm or an airlock. It’s possible that the motorised valves in the boiler could have failed, you don’t have enough water in the boiler, or the thermostat is not working correctly.

Suggested fix

Check the pressure gauge to make sure there’s no problem with the boiler’s pressure. You should also check the thermostat. If the readings seem fine, call in a Gas Safe registered engineer to troubleshoot and fix the boiler.

Radiators not heating up

Radiators not heating is a problem that affects many boiler brands. There are several reasons for this which include the build-up of sludge or air in the system.

Suggested fix

If the problem only affects the bottom of the radiator, you can try bleeding the radiator. If your system has been active for a couple of years, you should consider having a power flush done to remove the sludge.

Leaking or dripping

If the boiler leaks, you shouldn’t repair it by yourself. Boiler leaks are often a result of a bigger problem which you need an engineer to assist you with. In most cases, the leak is caused by a faulty internal component like a worn-out seal or a loose pressure valve.

Suggested Fix

Once you locate the leak, you need to call in a Gas Safe registered boiler engineer to identify the source of the problem and fix it. This requires the boiler to be opened and this should only be done by a trained professional.

Boiler keeps turning off

If the boiler keeps going off, it could be as a result of low water pressure, weak water floor because of a blocked or closed valve or a problem with the thermostat.

Boilers often go off to prevent further damage. As such, it’s not advisable to turn the boiler on again before determining what the problem could be.

Suggested fix

You need to start by finding the cause of the problem. If the boiler has low pressure, find the external filling loop and use it to add water into the system until the pressure gauge reads about 1.5 bars.

If it is any other problem, you will need to call in an engineer to assist you to determine the problem and fix it.
