Best boiler guide : condensing oil boiler

condensing oil boiler are becoming increasingly popular, yet there is still a lot of confusion surrounding them. So what exactly is a condensing boiler? How does it work, and why should you consider installing one in your home? In this article we take you through everything you need to know about condensing boilers

What is a condensing oil boiler?

The condensing oil boiler is a modern, energy efficient, and cost effective way to heat your home.

Unlike conventional boilers, it doesn’t lose energy through the chimney and so can be smaller in size. This makes them more compact and discreetly installed in retrofit applications where room space is at a premium.

The condensing technology means that less heat is lost from the system – so even though it’s smaller than a conventional boiler, it still produces enough hot water for your home (up to 100 litres per minute).

What are the disadvantages of a condensing boiler?

  • Condensing boilers are more expensive.
  • Condensing boilers are more complicated to install.
  • Condensing boilers are more expensive to maintain, as they require regular cleaning and servicing.
  • The condensate removal is more complicated with a condensing boiler than it is with an open-vented system, so you should consider this when choosing your heating system: if you can’t handle regularly emptying your boiler’s tanks, then a condensing boiler may not be best for you!

Are condenser oil boilers more efficient?

You may be wondering, are condensing boilers more efficient than standard boilers? In short, yes. Conventional oil boilers waste a lot of heat energy because they use a single stage process to heat water and release some of this energy in an open flue system. However, when you add a second stage to your condensing boiler (the “condenser”), it is able to recapture waste heat from the flue gas released by the first stage heating process and transfer it into your hot water system – making it far more efficient overall!

Are condensing boilers cheaper to run?

When you’re looking for a boiler that’s going to help you cut down on your heating bills, it’s important that you consider how much energy the unit uses. A condensing boiler is more efficient than a conventional boiler because it uses less fuel to produce the same amount of heat.

Condensing boilers are also more efficient in another way: they have a higher thermal efficiency rating, which means that they can transform more of their fuel into heat than other types of boilers.

How long will a condensing boiler last?

This is a question that has been asked many times over the years, and it’s not always an easy one to answer. Boilers come with different warranties, so the length of time for which you can expect your new boiler to last will depend on what type of warranty was offered with your purchase. If you’re buying a secondhand boiler, the answer becomes even more complex as there’s no telling how old it actually is or when it may require repair or servicing in future.

When choosing a new condensing oil boiler, whether it’s gas or LPG powered, make sure that you find out how regularly they need servicing and check if there are any particular guidelines regarding maintenance before signing up for an installation package from your local heating engineer.

Is a condensing boiler the same as a combi boiler?

A condensing boiler is different to a combi boiler. A combi boiler heats water, which is then used to both heat your home and provide hot water for showers and baths. A condensing boiler uses the heat from the flue gases to heat the water in your radiators, as well as providing hot water. The main difference between these two types of boilers is that when you use a combi boiler, some energy is wasted in heating your loft space with cold air released through vents in your roof and any excess heat not used goes out through an exhaust pipe attached to it.

However, with a condensing boiler all this unwanted cold air gets trapped and taken away by the fan inside it before it reaches the flue outlet – so there’s no waste at all! And because they’re more efficient than ordinary boilers (and therefore produce less CO2), they are more environmentally friendly too!

Is a condensing boiler the same as a combi boiler?

A condensing boiler is a type of water heater that improves efficiency by reusing excess heat produced in the process of heating water. A combi boiler, on the other hand, is a system that incorporates both a traditional storage tank and a modern energy-saving system.

The most significant difference between these devices is that while combi boilers use some energy to heat water before it enters your home (which makes them more efficient), condensing boilers don’t waste any extra energy—they simply reuse what they already have.

While it might seem like a no-brainer to opt for an eco-friendly option like this if you care about saving money, there are many factors you should take into account before making your choice: cost upfront; lifespan; installation costs; maintenance requirements; and more!

Are condensing oil boilers any good?

If you’re thinking about installing a new oil boiler, it’s important to understand which type of boiler makes the most sense for your home. A condensing oil boiler is considered more environmentally friendly and more cost-effective than traditional boilers because it is more efficient and reliable in use.

Additionally, this type of system has been shown to be much less prone to problems with moisture accumulation—which can cause major damage over time—so that’s another benefit. The bottom line: if you want an energy efficient way to heat your home and save money on monthly utility bills, then a condensing oil boiler may be the right choice for your home!

What are the benefits of a condensing boiler?

You may be wondering what the benefits of a condensing boiler are. Well, here are just a few things that you should know:

  • Condensing boilers are more efficient than non-condensing boilers. The basic idea behind this is that when water vapor cools down enough to become liquid again, it absorbs heat from the surrounding air and then turns back into gas. When it does this inside your house instead of out in the open air, your home stays warmer for longer—which means you don’t have to use as much energy to heat up your place!
  • Condensing boilers save money on heating bills compared with conventional models because they’re more efficient at turning fuel into usable heat in households where there aren’t many people living at once (i.e., single-person households). This is because they require less fuel per person per day: while non-condensibles need about 50% more gas than their counterparts do during colder months when everyone’s in bed all day long but still needs warm showers before going out again after work; on top of reducing CO2 emissions by 30% over traditional units due partially due their inherent design

How much can you save with a condensing boiler?

So, how much can you save with a condensing boiler? The answer depends on your current energy usage. For example, if you currently pay $1,000 per year for heating and hot water, a condensing boiler could save you up to 60% on that cost. But if your annual bill is $2,000 or more (the national average), then it might be hard to notice any difference at all—especially when factoring in the higher initial costs of installing a new system.

So how do you make sure that the investment is worth it? It’s important to first make sure that the company offering services has been certified by either Energy Star or Natural Resources Canada (NRCan). These certifications ensure that all of their products meet certain standards so they’ll perform well without costing too much money over time. Once this has been confirmed then all that remains is making sure there are no hidden costs involved during installation like extra piping materials needed for proper installation which could increase initial costs significantly but not necessarily provide additional savings later down the road due to increased efficiency provided by these extras being installed properly from day one instead of after initial purchase only because they weren’t thought about originally before buying equipment later down road once everything was already paid off!

what is the best oil condensing boiler to buy

The best oil condensing boiler is one that suits your home and lifestyle. A lot of people think that the right type of boiler will save them money, but this isn’t always the case. If you don’t switch to a new system, then you won’t save anything at all.

Before buying an oil condensing boiler, find out how much energy you use and how much you can save by switching to this type of heating system. You should also know what type of boiler you have now since it’s important when choosing a new one. If necessary, contact an engineer who understands this kind of heating source so they can help decide which one is best for your needs

how much does a condensing oil boiler cost

It can be difficult to determine the cost of a condensing oil boiler as it depends on many factors, including the size of your home and the brand you choose. Newer condensing boilers have become more efficient and are cheaper to run than older ones, so if you’re looking for an upgrade then it’s worth checking out some options online or in store.

If you’re replacing an old model with a new one, then there will be no payback period as it’s essentially a straight swap. However, if you’re building from scratch then there may be some costs associated with fitting out your new heating system before installation: installing pipework behind walls or floors; connecting gas pipes; connecting water pipes; connecting electricity supply cables and wires etc.. These costs vary depending on how far away these different elements are from each other within your property (usually around £500-2k).

A typical 5 bedroom house would need between 2-4kW per hour of heating output – this would give around 3000kWh/year at full output which would cost around £1200 per year (assuming average energy prices) – but by fitting a condensing boiler instead this could reduce by 30% which equates to savings of up to £240 per year in most cases!


So, there you have it! A condensing oil boiler is a good choice if you want to save money on your energy bills and make the most of your home. With their efficiency and low running costs, they are an environmentally friendly choice that will save you money over time while also reducing carbon emissions.
