    Where are heat only boilers usually located?

    These boilers directly provide heating and hot water from a storage cylinder, usually installed in the airing cupboard in your kitchen.

    A tank, usually in your attic, would supply the boiler with cold water, using gravity because that’s where they work best.

    Of course, the expansion cistern is separate from the boiler. This means that this boiler system needs more space as a result.

    Price Range:

    The Heat-only boilers differ greatly in price depending on the brand in question. Moreover, these models usually start at £500, and reach up to £2000 for some of the more well-known brands and models.

    Heat-only boilers are perfect for larger homes as they provide a high flow rate, are able to meet high hot water demands, and you are able to use multiple taps or showers at any given time.

    They will, however, need more space than other boiler types such as the combi boiler. In another case, the use of hot water is limited by the size of your cylinder. So once it’s empty, you have to wait for it to reheat.

    What to consider when getting a heat-only boiler?

    Firstly, the cost of installing a new heat only boiler depends on whether you have a similar system in place at the moment.

    A heat-only boiler needs the use of two water cylinders, one in the attic and the other, usually in the airing cupboard.

    It is usually less expensive to upgrade from a similar system where the external pumps are already in place than to convert your current plumbing to fit a new heat-only boiler.

    It’s important to place safety ahead of cost-cutting when installing a new boiler, .

    Always ensure that your boiler engineers are gas safe registered because this will ensure that your installation will meet the legal and safety guidelines.

    For one thing, always check the quality and standards of the work that they carry out because this will ensure that you are happy with the quality of work.

    What are the benefits of a regular boiler?

    Replacement is simple and easy

    Replacing your old regular boiler with a newer version is less costly and damaging to your home. So it’s always the safer option to go with if you don’t want to spend a lot or worry about damages.

    Meets your high demand of heating and hot water

    If you have a home with multiple bathrooms, then a regular boiler is a great choice. It can meet your demand for hot water and heating. With a large capacity to store hot water, it means that you can use several taps and outlets at the same time.

    More efficiency

    Older boilers with no condensing technology should be replaced with a condensing boiler. Condensing boilers are more efficient and consume less energy. As a result, they will reduce the cost of your heating bills. Nowadays, some regular boilers are 97% efficient.

    Able to have an immersion hearer as a backup

    A backup immersion heater would make sure that you don’t go out without hot water in case you boiler breaks down. The immersion heater would be fitted in the hot water cylinder.

    Solar compatibility

    presently, you can use solar thermal panels to produce hot water using solar power. Just make sure that your cylinder and the model you buy are compatible with solar thermal.

    What are the disadvantages of regular boilers?

    Hot water isn’t always instant in busier times

    Once you use all the stored hot water in your cylinder, you have to wait for some time to be able to use hot water again. Always buy a cylinder with the capacity to meet your hot water demands and needs.

    Needs lots of space

    Regular boilers need space for the water tank and the hot water cylinder. That’s why it’s not a good choice for smaller homes that don’t have much space. For smaller homes, a combi boiler is more suitable.

    Installation can be costly

    Because there are many parts to be installed around the house, a new boiler installation can be pricy. Aside from being expensive it can also take a lot of time.

    What is meant by a Condensing Boiler?

    The terms condensing and non-condensing can be confusing to people shopping for a new boiler.

    Presently, it is stated by law that new boilers must use condensing technology. In short, you don’t have to worry about getting a condensing boiler.

    Condensing is not a type of boiler, but rather a technical feature. In a Condensing boiler you get a much bigger heat exchanger. They also produce additional heat from the fuel. The same fuel that would have been wasted in a non- Condensing boiler. As a result, they are more efficient.

    non-condensing boilers are less efficient by 50% since a lot of heat was lost in the combustion exhaust gases. On the other hand, new boilers would capture this heat and use it to heat water.

    condensing boilers are energy efficient by 90%. They use excess energy to heat your property. Not to mention, they are environmentally friendly and reduce your heating bill.

    • A Combi boiler installation should have one energy-saving feature.
    • Thirdly, you should have functioning time and temperature controls.

    FAQ’s

    How long do heat only boilers last?

    A good boiler should not only heat your home efficiently but also be able to do it for a long time. If you have newly bought a new boiler, you do not have to worry about getting a replacement for many years. Most modern boilers last for anywhere between 10 to 15 years on average.

    What is the difference between a heat only boiler and a system boiler?

    Heat only boilers (conventional or regular) work with a cylinder in the airing cupboard. System boilers are more than often found in modern homes with an ‘unvented’ hot water cylinder.

    What does heat only mean?

    A heat only boiler heats a home by using a cold water tank, a hot water cylinder, in addition to a feed and expansion tank. Heat only boilers are usually found in larger homes because they are able to supply hot water to multiple radiators, taps and showers all at the same time.

    How long does it take to install a regular boiler?

    A regular boiler can take between 1 to 3 days. The complexity of the installation will determine the duration. A like-for-like boiler replacement would be the quickest to do. However, replacing a different kind of boiler would take longer time to finish. For instance, a combi boiler replaced with regular boiler will require installing a hot water cylinder, a tank and re-routing the pipework. Lastly, moving your boiler would also increase the installation time.

    Is a regular boiler the right choice for me?

    To get what you exactly need, you should take a look at the pros and cons of regular boilers. There are a lot of things to think of when it comes to choosing the most suitable boiler for you. So here are some of the most important things to keep in mind:

    How do regular boilers work?

    It is all pretty simple. Basically, a regular boiler will take water from the tank to provide heating. It is important to place your tank as high as possible to have a better water flow in all the system.
    A heat exchanger warms up the cold water once you turn on the hot tap or switch on the heating. After that the hot water moves to the hot water storage cylinder where it is kept and circulated. Then valves will direct hot water to the heating system or the taps and outlets.
