‘Which oil boiler should I buy?’ is an important question to ask if you’re in the market.
Oil boilers in principal, operate in a similar way to any gas-powered system, in that they both use their respective fuels to fire up the boiler and heat water. When this is done you have heat provided across the property, through the radiators and out the taps, so you can do all those important jobs like the washing up!
The key thing to remember when choosing which oil boiler is right for you, is that the fuel will be delivered into your tank. This fuel will need to be stored somewhere on the property, but it means you can always be aware of what sort of rate you’re going through the fuel.
All oil boilers are condensing, including regular/open vent boilers, but deciding which one depends much more on what sort of property you’re currently living in.
The main difference of combi boilers against the rest of the boiler types out there, is that they only heat the water when you actually need it. This way, energy bills are largely cut down as there’s a lot less work put in to get the same result.
How do Oil Boilers actually work?
When deciding which oil boiler to buy, understanding how they work can be just as important as their pros and cons. Essentially, once the oil for the boiler is set alight, cold water can be warmed up by the heat exchanger that either comes out your taps and showers, or through the central heating system.
Depending on whether you have a combi boiler or a regular boiler, the water itself would come from either the mains supply, or in a cold water storage tank in the attic. Some see this as a decision-maker – if you have any concerns about limited space or potentially wasting energy then a combi boiler is probably the best choice for you.
When choosing which oil boiler to buy, the main thing to remember is the nature of the fuel itself. An external storage tank is needed to store your oil but don’t worry – these are designed to house enough oil to last normally for about 6 to 9 months, so you always have ample time to plan ahead. While there are options for what size tank you can go for, the maximum size for a domestic storage tank is 2,500 litres. However, you should bear in mind that most domestic applications require about 800 to 1,200 litres.
As well as this, all modern oil storage tanks have to be double skinned, which is also more commonly known as ‘bunded’.
Many oil boilers today use kerosene – also known as C2 – as their fuel, which is one of the cleaner oil types available.
Which Oil Boiler Efficiency
Modern condensing oil boilers have an efficiency rating from 89% up to 93.3%. So, if you replace your old boiler for new condensing one, you would be getting a more energy efficient system for your money.
Whilst budget and price play a big part, it is essential you have the right model and size of boiler to meet your requirements.
As a rule of thumb today, oil boilers are required to have an efficiency rating of at least 86% in order to adhere to building regulations. That means that by choosing an oil boiler that is right for you, you can be reassured you’re getting a good quality unit with excellent efficiency. For old systems that are past their prime, you might be looking around 60-70% but at this point, you’ll definitely want to be looking for a replacement.
However, there are many oil boilers available on the market today along with more modern controls like a smart thermostat, for example a Nest Generation 3 Learning Thermostat. With these smart controls combined with a new efficient oil boiler, your energy efficiency will exceed well over 90%.
So, with all that in mind, you have a much better idea of whether having a new boiler installed will save you from further repair costs and headaches with your existing boiler.
Let’s not forget that the older the boiler is the harder it is to get parts; parts are expensive especially for oil boilers and it can be a costly call out too.
With all this considered, you should choose a qualified, reliable professional like B T Morgan who can provide the service that you need.
All installers need to hold the right qualifications to install or replace an oil boiler. These qualifications are usually achieved by attending a BPEC training centre for assessment and examination. Following this, a certificate is issued and is valid for 5 years.
OFTEC (Oil Firing Technical Association) is one of the most recognised certification body for competent persons installing oil boilers.
Always check with whatever company or engineer you choose that they have these qualification/certifications (or equivalent), before replacing or installing you new oil boiler. You can always check OFTEC’s find an installer page to see if the company you are interested in carrying out the work for you is approved with them. This will give you piece of mind.
