Boilers account for around 60% of the carbon dioxide emissions in a gas heated home. By replacing an old G rated boiler with a new high efficiency condensing boiler and improving your heating controls, you will significantly cut your home’s carbon dioxide emissions and could save as much as £225 a year. If you are a senior citizen ask Atlantic how we can save you money on installation costs.
The current lifespan of a boiler is around 12 years and fitting an A rated high efficiency condensing boiler with the correct heating and hot water controls can make a huge difference to your heating bills over time.
What is a high efficiency condensing boiler?
A high efficiency condensing boiler works on the principle of recovering as much as possible of the waste heat which is normally wasted from the flue of a conventional (non-condensing) boiler. High efficiency condensing boilers convert 86% or more of their fuel into heat, compared to 65% for old G rated boilers.
Is my boiler a high efficiency condensing boiler?
If your boiler is an A-rated boiler according to SEDBUK ratings then it is a high efficiency condensing boiler.

Heating controls will keep your home at a comfortable temperature, making it warm when you want it but switching off when you don’t. They include: a programmer, a room thermostat, a combined programmable room thermostat, a cylinder thermostat and Thermostatic radiator valves (TRVs).
Frequently asked questions
So, how much energy and money could I really save with a better home heating system?
By fitting a condensing boiler and improving your heating controls you could save up to £225 a year and 1.1 tonnes of CO2 .
Is a combination condensing boiler more efficient than a regular condensing boiler?
A combination boiler can be more efficient because of the way it supplies hot water to your home. Other types of boilers produce hot water and then store it in a cylinder for use as and when it is needed. This is quite an efficient process – but if the hot water is not used before it cools down, then inevitably some heat will be wasted.
Combination boilers are most suitable for smaller homes but can also suitable for larger homes depending on your hot water requirements. Atantic can advise you which type would suit your home best.
Are condensing boilers overcomplicated and unreliable?
In a word no. The main difference between non-condensing boilers and condensing boilers is the design of the larger heat exchanger in the latter. Another difference is the condensing process itself: when the flue gases cool, water condenses inside the boiler and needs to be drained away. But this shouldn’t cause any problems if the boiler is fitted properly by a registered company such as Atlantic Plumbing & Heating.
I want to replace my old boiler. How do I know what size of new boiler to get?
The type and size of your new boiler will depend on a range of factors like the size of your property, how well it is insulated, and the type of fuel and heating system you use to heat your home.
Again, Atlantic engineers will be able to advise you on the type and size of boiler best suited to your home.
How often should I get my boiler serviced?
It’s important to have any gas or oil fired appliance like a boiler serviced once a year. The flue will need checking to make sure it is clear, and our engineers will also check that your boiler is running safely and efficiently for you.
It’s best to check with your manufacturer about service schedules: as some boilers may need servicing more than others.
How can I make my central heating system more efficient without spending lots of money?
Your first step should be to make sure you are using your heating controls correctly. Review your boiler thermostat, cylinder thermostat, time programmer and thermostatic radiator valve settings and re-set them to match your needs more closely in terms of timing and comfort. Also keep the system clean – see our power flush section.
Control individual room temperatures with thermostatic radiator valves
If you have radiators, make sure that they are not blocked by furniture or curtains. Any obstructions will stop air flowing freely around the radiators – and so reduce their overall efficiency. Fit reflective insulation panel boards on the wall behind the radiators, especially if it’s an outside wall. Rigid reflective radiator panels are an ideal solution if you don’t want to take your radiators off the walls.
Also, try insulating your pipes in unheated parts of your home like the loft. Insulation material for a standard 15mm pipe costs around £1.50 per metre and will reduce heat loss. Fit a jacket, 3 inches or 75mm thick, to your hot water cylinder too if it isn’t already insulated. Jackets cost around £12 and could save you around £35 a year.
Getting your boiler serviced once a year will make sure it continues to work as efficiently as possible.
I don’t get consistent heat throughout my radiators. What can I do to fix this?
Air can stop water from reaching all parts of the radiator and decrease its effectiveness. A radiator that needs bleeding will not be as warm as other radiators, and it’s heat will be concentrated at the bottom. The heating system should be switched off when you bleed radiators to stop more air from entering the system. Hold a tea towel underneath the radiator key and open the valve very slowly as dirty water can spray out.
Energy Efficiency Bands
SEDBUK efficiencies are expressed as a percentage, and an A to G scale of percentage bands was also in use until October 2010. This has been withdrawn to avoid confusion with the proposed European energy label using similar ratings based on different principles. The meaning of the SEDBUK bands was as follows:
