What exactly is ErP? Explained: Boiler Efficiency
The quality of a boiler indicates how efficiently it transforms fuel into heat for the house. Many modern boilers are over 90% powerful, which ensures that almost all of the fuel is converted into usable electricity.
Boiler quality can deteriorate with time, but there are a few things you can do to make your boiler more effective.
What exactly is boiler efficiency?
The efficiency of a boiler is measured by how much fuel is converted into useful energy and how much fuel is lost in the process.
A high-performance boiler with a 94 percent efficiency rating will waste just 6% of the fuel it consumes. We mean the gases that you see released outside from the flue pipe when we say ‘waste.’ To bring boiler quality into financial context, for every £1 spent on heating your home with a 94 percent effective boiler, 6p is wasted.
An unreliable boiler will use more electricity, increasing the heating bills, which will fail to meet demand. Older boilers could be running at performance ranges as low as 60% to 70%.
The percentage of boiler efficiency corresponds to the ErP and SEDBUK energy labels.
What exactly is ErP?
The Energy Related Products Directive (ErP) was adopted as part of the EU’s efforts to phase out obsolete appliances.
ErP refers to both domestic and industrial heating items in Europe and has two main advantages:
Fuel labelling should be clear so that people can select the most energy-efficient goods. This makes reducing greenhouse dioxide and saving money on energy bills simpler.
ErP adopted new ‘Ecodesign’ rules for suppliers. Before a commodity, such as a furnace, will be sold, it must first meet higher energy efficiency requirements. Boilers that do not meet the minimum specification are no longer made or sold.
Under ErP, boilers must be numbered with an efficiency rating varying from G (lowest efficiency) to A+++ (highest efficiency) (highest efficiency).
ErP (Energy Reduction Potential) of a Boiler
It is the duty of boiler suppliers and dealers to ensure that their items are appropriately branded. In addition, the installer who instals your new boiler must evaluate the overall energy efficiency of your heating system. For example, if they instal an A-rated boiler with smart thermostat controls, the controls can increase your system’s performance, and they must provide you with a rating for both.
What exactly is SEDBUK?
When ErP ratings were implemented, they took the place of SEDBUK. SEDBUK, which stands for Seasonal Efficiency of a Domestic Boiler in the United Kingdom, awards efficiency ratings to boilers ranging from A to G. Despite the fact that it has been replaced, many boiler manufacturers continue to display the SEDBUK quality ratings of their boilers.
Why is the efficiency of a boiler important?
Boiler quality is important for a variety of factors. An powerful heating system emits less carbon dioxide into the atmosphere because it uses less electricity. This is good news for the world, as pollution is a big contributor to climate change.
If helping the world wasn’t enough, you’ll still be helping your bank account. Since an effective furnace uses less power, you might save up to £305 a year on your heating bills.
What is the productivity of your boiler?
As previously said, all boilers have an ErP efficiency rating that indicates how well the boiler can operate. On our Boiler Review Tool, you can see the efficiency ratings of all gas, diesel, and electric boilers available in the UK.
“The efficiency of a boiler can steadily decline over time. This is one of the reasons why replacing a boiler after 8 years is a smart decision. Otherwise, efficiency will begin to fall, and the heating costs will rise.”
To ensure that modern boilers meet high performance requirements, a new law enacted in April 2005 mandated that all gas boilers manufactured in the United Kingdom use condensing technology. A condensing boiler, as opposed to a non-condensing boiler, will absorb some of the heat that would otherwise escape through the flue tubing. This means that you can generate more heat from the same amount of petrol.
When a boiler is used to heat a house, water vapour is produced (steam). This vapour, along with any heat it produces, is expelled by a non-condensing boiler through the flue. The Flue Gas Heat Recovery device in a condensing boiler, on the other hand, absorbs this heat and uses it to steam up the central heating.
If your gas boiler was installed after April 2005, it is condensing, and therefore more efficient than a non-condensing boiler.
Quick Methods to Increase the Efficiency of Your Boiler
Maintaining the health of your boiler would cause it to operate more efficiently. So, here are seven things you can do to improve the efficiency of your boiler.
Annual boiler maintenance.
It is important to get your boiler serviced on an annual basis if you want it to operate smoothly and successfully for as long as possible. A boiler service entails a Gas Safe certified engineer inspecting and examining the gas boiler in the same way as a vehicle has a MOT.
If you have an oil boiler, you would need an OFTEC technician to perform your annual boiler operation.
Radiators should be bled.
Having the effort to bleed your radiators on a daily basis will keep them working efficiently. Air may penetrate the heating system and create a blockage over time. As a result, the upper half of the radiator would be colder than the rest.
Bleeding the radiator allows air to escape from the heating system, allowing hot water to flow all the way around the radiator. You’ll be much more relaxed as a result, and your boiler won’t have to strain as hard.
Maintain adequate water pressure.
A adequate amount of water pressure allows the boiler to work effectively. If the boiler pressure decreases, it must work harder and use more fuel to heat your house.
You should use the pressure gauge to monitor the pressure in your boiler. It should preferably be between 1 and 2 bar, but you should still consult the boiler manual for manufacturer’s instructions.
Boiler pressure may decrease steadily over time or abruptly as a result of a water leak or shortly after the radiators have been bled.
You can raise the boiler pressure yourself if you obey our step-by-step directions, or you can employ a specialist.
Insulate the cylinder and the tubing.
When it comes to making your house colder and lowering your heating costs, making sure your property is well insulated should be a top priority. Insulating the cylinder and valves is something that is often ignored.
A cylinder is not needed if you have a combi boiler, but it is required if you have a machine or a standard boiler. Wrapping the cylinder in plastic will make the hot water colder for a longer period of time. This means that the furnace would not have to heat the water as much, resulting in lower energy consumption.
Each month, turn on the heating (even during the summer)
Over the season, you may want to turn off your boiler and forget about it. Although this may help you save money on your heating and electricity costs, it is not good for your boiler.
“Running the boiler at least once a month during the summer will protect the pipes from freezing and defects from forming further down the line.” This way, you’ll know you’ve got a reliable and powerful heating device ready to keep your home warm all winter.”
Utilise a smart thermostat.
Greater control leads to greater productivity. And, with a smart thermostat, you would have unprecedented power and monitoring of your heating system.
Nest and Hive are two of the most common smart thermostat models, and they provide features such as:
And if you’re not at home, you can monitor and adjust the heating from your mobile or tablet.
Tracks environmental conditions and then changes the heating automatically. Adapts to the specific home heating patterns.
It can detect when the property is vacant using Geolocation technology, meaning you will never have to think about leaving the heating on again.
You should replace your boiler.
Any boiler would eventually need to be replaced. If your boiler was built more than eight years ago, it’s time to think about repairing it. Modern boilers are incredibly powerful, and investing in a new boiler will reduce your heating bills by up to £305 per year. Not only can you save money on heating costs, but they will also be much more efficient, reducing the likelihood of a potentially expensive fix.
