Diesel Boiler Guide: Diesel Combi Boiler Price List 2022

The diesel combi boiler is an efficient boiler that can last for many years. Combination boilers are also known as dual-fuel boilers because they can run on both oil and gas. If your home has an existing oil-fired boiler, then it’s likely that you’ll need to replace it before upgrading to a new system with an integrated gas-condensing boiler. The good news is: there are plenty of models available at affordable prices which makes the investment worth it in the long run! So how much does it cost?



Are diesel combi boilers efficient?

Diesel combi boilers are more efficient than oil boilers, although the difference is not necessarily huge. This is because the modern diesel boiler features a much-improved combustion system and a higher efficiency rating than older models. The latest models can achieve a condensation rate of up to 95%.

Combined-cycle boilers have much greater energy efficiency than single-cycle models. They use two different types of fuel – gas, and oil – in order to produce more heat per unit of fuel used. As well as being more economical, these can also be cheaper to run in terms of initial investment costs because you don’t need an expensive dual-fuel appliance fitted in order for them to work efficiently.

Diesel combi boilers are more efficient than oil combi boilers but still fall short when compared with their combined cycle counterparts.

Q What kind of fuel does your boiler use?


How efficient are oil combi boilers?

Oil combi boilers are more efficient than gas, electric, and even LPG systems. They can be used to heat water and provide central heating for your home or business. The energy efficiency of a boiler that uses oil as its fuel source is measured by the rate at which it heats the water. This is known as its thermal efficiency.

The thermal efficiency of a boiler depends on many factors, but one of the most important ones is how well-insulated your home or building is. Boilers are often installed in buildings with poor insulation so they will be less efficient than they could be – though this isn’t always necessary because there are other ways to reduce energy costs!

How long does a diesel combi boiler last?

While it’s impossible to predict exactly how long a diesel combi boiler will last, you can expect to get at least 10 years out of one if kept in good condition. The lifespan of your boiler will depend on the amount of use it gets and the size of your home. If you have a large family that lives in an old house with low insulation, then you may find yourself replacing your boiler sooner than average. On the other hand, if most people in your household are small children or elderly relatives who rarely take baths or run water heaters at full capacity, then chances are good that yours will last longer than average.



How does a diesel combi boiler work?

The diesel combi boiler is a high-performance, low-emission boiler that uses a combination of combustion and hot water storage to provide heating and hot water. The heat generated during the combustion process passes into an enclosed primary heat exchanger (PHE) where it is transferred to the water. The PHE is surrounded by an external casing made of stainless steel or mild steel (steel with a small amount of nickel added). This casing acts as an insulating blanket, preventing heat from escaping from the PHE.

After leaving the PHE, this heated water circulates through copper pipework within your heating circuit before entering individual radiators throughout your home. As it passes through each radiator, some of its energy is lost due to friction and other factors such as poor connections – but much more energy is lost in transmission via central heating pipes and central heating systems which are usually poorly insulated and leaky or corroded due to age.

When you’re not using your home’s hot water supply, cold mains water can be used instead of warmed-up mains cold feedwater so there’s no need for any expensive pumps or other equipment required when using tankless systems like electric instantaneous or LPG condensing types.

What are the advantages of a combi boiler?

  • Combustion efficiency: Since a combi boiler is an indirectly fired appliance, it’s more efficient than other types of boilers. This means that you’ll be able to improve your home’s energy efficiency and reduce your fuel bills with a combi boiler.
  • Reduced fuel costs: A typical oil or gas boiler uses about 5-10% of the heat generated for space heating purposes and up to 90% for hot water production, but this can vary depending on the size of your home. As mentioned earlier, a combi boiler has better combustion than an open-vented system (the most common type of central heating system). Because it uses less heat for water production, there is less waste heat produced by your heating system overall

How much does it cost to replace an oil-fired boiler?

  • What is the cost of repairing an oil-fired boiler?

The cost of repairing an oil-fired boiler depends on how much work needs to be done. If you need to replace any parts or components, that would be included in your quote. You may also have to pay for labor to put the new parts in place and test the unit after installation. Your repair company or plumber should give you a detailed breakdown of everything they will do when they come out for service calls like this one, so make sure you ask questions if there are any things unclear about their process or pricing structure before signing off on anything!

  • What does installing an oil-fired boiler cost?

Installing an oil-fired boiler will require some heavy lifting (an experienced professional can help), but once it’s up and running, maintenance costs are minimal compared with other types like gas-powered models that require constant upkeep due to their fragile nature.



There are lots of advantages to using a diesel combi boiler. They’re more efficient than standard boilers, so they use less fuel and generate lower emissions. They can also be used for heating or hot water and are available in various sizes to suit different homes and businesses. It’s important when choosing one that you choose a trusted supplier who will give you great advice about which model is best suited to your requirements both now and in the future!
