Choosing the right boiler for your property is an important decision. Oil and gas boilers are two common options, each with their own benefits and considerations. In this blog, we’ll explain the key differences between the two, helping you decide which one suits your needs.
Fuel Supply & Storage
The main difference between oil and gas boilers is the way they are fuelled. Gas boilers are powered by natural gas, which is delivered directly to your property through the energy grid. This means there’s no need to store fuel on-site, making it a convenient option for homes and businesses connected to the gas network.
Oil boilers, on the other hand, require heating oil that is stored in a tank on your property. You’ll need to monitor your fuel levels and arrange for regular deliveries to avoid running out. This can be less convenient, but it’s a practical choice for rural or remote properties without access to the gas grid.
Installation Considerations
When it comes to installation, gas boilers are often more compact and can fit into smaller spaces, such as kitchen cupboards. They’re usually installed indoors, which is ideal for properties where space is limited.
Oil boilers are often larger and noisier, so they’re commonly installed outdoors. While this saves space inside your home, it might not be practical for smaller properties or those with limited outdoor space.
Efficiency & Environmental Impact
Gas boilers are generally known for their energy efficiency and lower carbon emissions. Natural gas burns more cleanly than oil, and liquefied petroleum gas (LPG) is an even cleaner-burning alternative that produces less soot and ash.
Modern oil boilers can be very efficient too, with some condensing models achieving up to 95% efficiency. However, oil does produce more carbon emissions compared to gas, so it may not be the best choice if you’re looking to reduce your environmental footprint.
Costs Of Installation & Running
The cost of installing and maintaining a boiler varies depending on the type and size of the unit, as well as the specific needs of your property. Gas boilers are often cheaper to maintain, and their running costs are usually lower because natural gas prices tend to be more stable.
Oil prices, on the other hand, can fluctuate due to changes in the global oil market. During colder months, demand for heating oil increases, which can drive up costs. While oil boilers can be economical to run when prices are low, they can become expensive during peak demand periods.
Suitability For Different Properties
Gas boilers are a good choice for properties connected to the gas grid. They offer convenience and a steady supply of fuel. They are well-suited to urban and suburban areas where access to the gas network is common.
Oil boilers are ideal for rural homes or isolated properties without access to the gas grid. They provide a reliable heating solution, but users need to manage fuel storage and deliveries, which may require extra planning.
