Oil Boiler Types Explained

External Oil Boiler Installation Bristol

Oil Combi Boilers

Combi (or combination) oil boilers produce both heating and hot water on demand, without the need for a cylinder. They are very economical and a great solution for properties with limited space thanks to their compact, single unit form.

Oil System Boiler Installation Bristol

Oil System Boilers

System boilers use a cylinder to store hot water, but the majority of heating still takes place in the boiler itself. These are ideal for homes with multiple bathrooms where hot water is in high demand.

Oil Regular Boiler Installation Bristol

Oil Regular Boilers

Regular oil boilers are more traditional, and they use a hot water cylinder as well as cold water and an additional storage tank, usually in the loft space. These are often an excellent option for replacing existing old oil boilers without having to update your entire central heating system.

Helping you Select a New Oil Boiler

Looking for a new oil boiler?  Mains connected gas isn’t always available so oil boilers are popular choice for more rural locations. Our central heating experts can help you choose the best oil boiler that’s perfectly suited for your lifestyle and household.

Firstly we’ll review your existing heating system, and then we’ll discuss your household’s heating and hot water requirements.

After a comprehensive review our friendly and skilled heating experts will give you a free no-obligation oil boiler quote for installation which reflects your household’s budget and lifestyle. We can also give you a selection of finance options to help you spread the costs.

Oil Boiler Installation Prices

We always try to offer highly competitive prices for new oil boiler installations.

It’s important to note that oil boiler installations aren’t always a ‘one size fits all’ as every home is unique and has different requirements. The total cost of installing a new oil boiler will vary based on the condition of your existing central heating system, the size of your property and the number of bathrooms you have.

Sometimes you may need additional work added to the quotation, eg. removing a hot water cylinder. However, if you are replacing an old oil boiler with a like-for-like replacement, this is often pretty economical.

What is the cost of a new combi boiler?

The cost of a new combi boiler depends on the size of your home and how many radiators you have. For example, a smaller one-bedroom flat with around five radiators will usually need a lower output boiler, which is typically more affordable. In contrast, a larger detached home with multiple bedrooms, bathrooms, and a higher number of radiators will require a more powerful boiler, which can increase the cost.

At Plumbco Heating, we offer a range of high-efficiency combi boilers to suit all property sizes and budgets. We’re happy to carry out a free home survey anywhere in Bristol and surrounding areas to recommend the right boiler for your home, with transparent pricing and no hidden fees.

During your installation

How long does a replacement boiler installation take?

In most cases, a new boiler installation with Plumbco Heating takes 1 day. If you’re replacing your old boiler with the same type in the same location, the job is usually straightforward and quicker.

However, if you’re changing boiler types – for example, upgrading from a regular boiler to a combi – or if you’re relocating the boiler to a different part of your home, the installation can take a little longer due to additional work like adjusting pipework and rerouting flues.

Not sure which boiler type is right for your home? Our friendly engineers are happy to talk you through the options during a free home survey, helping you choose the best boiler for your property and budget.

How efficient is my gas boiler?

Boiler efficiency plays a big role in how much you spend on your energy bills. The more efficient your boiler, the more heat you get for every pound you spend on gas, which can make a real difference to both your wallet and your carbon footprint.

If your boiler is over 10 years old, it may be running at just 60–70% efficiency, meaning a significant portion of your energy is being wasted. In contrast, every new boiler we install at Plumbco Heating is A-rated for energy efficiency, helping you save money on your gas bills and reduce your home’s environmental impact.

We’re also happy to share practical tips on how to get the most from your current boiler – like bleeding radiators, setting heating schedules, and installing smart controls.

👉 Thinking about upgrading? A new energy-efficient boiler could pay for itself over time.
