Combi Boiler VS Oil Boiler

When choosing which boiler is right for your home, there are many factors you need to consider. Immediately choosing the cheapest option may not pay off in the long run, as investing in a more efficient boiler will actually be more economical over time. You also need to check which kind of boiler will work with the set up of your home. The kind of energy accessible to your home will affect the boiler options available to you. To help you decide, we explore the difference between the combi boiler and the oil boiler. This will help you to understand which boiler is right for you and your heating needs.

What is a Combi Boiler?

A combi boiler provides hot water on demand. The combi boiler eliminates the need for a hot water storage tank, as the combi boiler is of an on-demand gas boiler design. It is possible to buy an oil-fired combi boiler, but gas and LPG models are more common. People living in smaller homes and flats may want to consider a combi boiler for its compact design. Those who are eco-conscious will be impressed by the combi boiler’s ability to conserve energy. As energy is not wasted by keeping water at a certain temperature throughout the day.

However, the combi boiler is tricky to install, and you must be prepared for any necessary rewiring and installation of new pipes to accommodate the plumbing. The combi boiler is an ideal choice for those who wish to see energy savings of up to 30%.

What is an Oil Boiler?

An oil boiler, as you can expect, is powered by heating oil which is supplied from tanks on your property. People who live in rural areas often use an oil boiler as they may not be able to access gas networks, but can rely on deliveries of heating oil. Nowadays, oil boiler designs are just as advanced as combi boilers, so they can provide hot water when necessary.

Oil has a higher energy density compared to natural gas. Oil boilers can achieve at least 95% efficiency when turning fuel into heat. If your home has the required fuel tank set up, then an oil boiler may be the right choice for you.

What are the Benefits of a Combi Boiler?

Cost and Energy Efficient

The combi boiler is the most popular boiler among homeowners in the UK. The cost and energy efficiency of the combi boiler aids its popularity, as it reduces gas and electric bills for your home. Replacing your old boiler with a new combi boiler could actually help you save up to £300 a year on your heating bills.

Installations are Typically Cheaper

Combi boilers are cheaper as they are way less complex than traditional boilers. This means that installations are often cheaper. It is also easier to find replacement parts for a combi boiler if necessary.

Hot Water Instantly

Combi boilers are also faster, as there is no water tank to heat up. Meaning you can have hot water on demand. The cold water from a combi boiler system is always safe to drink as it comes directly from the mains. This is not always the case with traditional systems, which may store
cold water in a tank before it is supplied to the rest of the house.

Less Issues

Combi boilers are also less likely to suffer from pressure issues, as the hot water is taken directly from the water mains. Another benefit of a combi boiler is the fact that it is cleaner, with less sludge build up. This is due to the water coming straight from the mains and not kept in a tank where rust can develop over time.

Easy to Service

Combi boilers are easy to service, as their popularity means the majority of boiler engineers are trained on how to repair and service them. It will be easy to find a qualified engineer in your area. As combi boilers are popular and more efficient, this can be a selling point if you wish to sell or rent your property.

Small and Compact

The small sizing of a combi boiler allows it to fit into small spaces. Making it ideal for small homes and flats which don’t have a lot of storage space.

What are the Benefits of an Oil Boiler?

Cost Effective for Rural Areas

Oil as a fuel is known to be efficient, so you will see a return on your money. If you live in a rural area, an oil boiler might be the best option as you may not be connected to a mains gas supply. Costs of an oil-fired boiler are usually lower than that of an electric boiler. And oil boilers are also energy efficient as they only heat water on demand.

No Contracts

Oil boilers also provide the homeowner with the freedom to change suppliers whenever, as there are no contracts with a mains gas supplier. You wouldn’t have this same freedom with a gas or electricity supplier. To save money, you can also buy oil in bulk, if you have a large enough storage tank. You can buy and store oil on demand, while the price fluctuates over the different seasons.

Uses Renewable Resources

Oil boilers can be used by renewable energy heaters, which allows the homeowner flexibility with their heating. Renewable technologies include solar heating and ground source heat pumps, which are both compatible with oil boilers. Supplementing your oil boiler with renewable energy heaters can bring your monthly fuel bills down even more over time.

Which Boiler Should I Choose?

Which boiler you should choose depends on your personal needs and your location. If you live in a small flat or home with little storage space, a combi boiler is most likely the right choice for you as it will be able to fit in your home.

However, if you live in a rural area, an oil-fired boiler may be the best option for you as a mains gas supply may be inaccessible.

Choosing your new boiler can be a difficult decison. But, with the benefits of both the oil and combi boiler laid out in this article, we hope that making the decision is a bit easier. As you can see there are benefits to both types of boilers. Your needs will depend on the boiler type you select to have installed in your home.

To Conclude: Combi Boiler VS Oil Boiler

When deciding between a combi boiler and an oil boiler it is important to keep several things in mind. It is a good idea to consider the size of your house, your location, how much hot water you need at a time, and the existing system in your home. Think about your heating and hot water needs.
