While the beautiful open countryside of Cheshire makes it an extremely attractive region to live in, many properties in the region do not have the convenience of a mains gas supply and instead rely on an oil boiler. Although oil boilers have traditionally been fitted inside the home, improved technology means that external boilers are becoming an increasingly popular option. So what are the advantages of an external oil boiler and why might it be the perfect choice for your home? We take a closer look.
Before we take a closer look at the benefits of replacing your existing boiler with an external oil boiler, let’s take a moment to look at the key difference between the two. They both work exactly the same way, however an external boiler features a weatherproof housing - meaning it can be located outside your home in a location of your choice. If you are replacing an existing internal oil boiler and have suitable space outside, then this could be an extremely attractive option for you.
There are several reasons why an external oil boiler is a great choice:
Switching from an internal system to an external oil boiler is a great way to free up valuable space in your home that you can put to other purposes.
Oil boiler technology has come a long way in recent years. Old boilers are often large and unsightly and can be difficult to work around when you want to improve the appearance of your home. With a cutting-edge external oil boiler, you can finally say goodbye to having a large and unattractive device inside your home and enjoy improved aesthetics instead, while still enjoying the convenience of an efficient and reliable boiler.
Although there have been drastic improvements with new technology, even a modern oil boiler will make a certain level of noise when operating. With a boiler located outdoors, this will never be a problem.
Carbon monoxide leaks, although rare, are nonetheless a real risk with both gas and oil boilers. Putting the boiler outside substantially reduces the risk of carbon monoxide leaking into your home.
When using an oil boiler, there is always the possibility of oil leakage, which can cause damage and odours which can be hard to remove. With an outside boiler, this risk is eliminated.
Locating your oil boiler outside can make it more accessible to engineers, minimising any disruption during your annual boiler service or maintenance.
Although the advantages of an external boiler are numerous, it is worth considering a few factors that you should bear in mind when making a decision.
It is important to make sure that you have a suitable outdoor location for the boiler within a reasonable distance to the rest of the system, including the oil storage tank. This is rarely a problem for properties that already rely on oil, but if you are uncertain then our experts are happy to advise further.
All boilers lose a certain amount of heat to the air around them, whether indoors or outdoors. With an internal boiler, this heat will escape into your home and therefore not have a negative impact. With an external boiler, a small amount of heat will be completely lost, which will slightly impact energy efficiency. Heat can also be lost from the pipes as it transports hot water from the boiler to the property. However, there are ways to protect against this, such as cladding. Your installer will be happy to advise.
The Worcester Bosch Greenstar Heatslave II is one of the leading external oil boilers and features cutting edge technology housed within a robust cabinet that protects it from the elements. It is suitable for small, medium and large sized homes with up to two bathrooms.
