Launched in September 2015, the European Energy Policy requires changes in the efficiency and type of heating systems permitted in European homes over the next several years.
Because of this, modern boilers have been forced to increase their efficiency by up to 50% in a short period of time.
In the U.K., modern British building codes require that all new gas replacement boilers installed in homes are high-efficiency and/or condensing boilers. The Sedbuk Seasonal Efficiency boiler rating system, which stands for Seasonal Efficiency of a Domestic Boiler in the UK, is a system used to classify a boiler according to how efficient it is in converting fuel into heat during peak seasonal times.
If the boiler is older than 10 years, the probability is high that it is not a condensing boiler and is therefore rather inefficient, and more costly to run (especially in winter!).
Ratings on new boiler systems are important and to us, we’d only recommend a boiler with an “A,” rating.
Having said this, with the new system it is more useful to use the efficiency class Sedbuk 2009 rating system if you are interested in how one boiler is compared to another. This is especially important when calculating long term running costs.
High Efficiency Boilers UK: Modern Boilers
Modern condensing boilers can be divided into three types, which are actually defined by the type of system used to supply central heating and domestic water.
From a combi boiler, which heats the mains water supply inside the boiler unit to provide hot water and heating, to a system and regular or conventional boiler which supplies the hot water and heating from a cold water storage tank and a hot water cylinder usually in an airing cupboard.
One of the main components in a new boiler is the stainless steel or aluminium , highly efficient heat exchanger which is used to heat and to supply the hot water, This is then returned to the radiators and is also fed to heat the water to supply quick on demand heated water to taps.
Most types of modern boiler systems use the same high-efficiency technology, but the best system for your specific home will depend on various factors, including the type of system already installed, the size and amount of the radiators, if any cylinders need removing or replacing and other factors.
It makes sense to use a boiler cost calculator to see what suits your home exactly. This way, it is an exact fit which will give you 3 boilers to choose from with cost to install, a calendar for a convenient install date should you need it, and even flexible financing.
High Efficiency Boilers: Identifying Information
Some parts of the world have colour-coded scales that help consumers compare the efficiency of different makes and models of boilers to get an idea of how much better they would be if they already had one.
For example, a modern condensing boiler would achieve an “A” and an older pilot, or conventional boiler a “G.” It is quite astonishing how quick the increased efficiencies have increased over such a short period of time.
Although the SEDBUK rating is still used in the UK, the scale is being replaced by the Energy-related Products Rating System (ErP) in the UK. Many boilers currently on the market do not meet this efficiency standard and we recommend consumers to check the efficiency class before purchasing or installing a boiler manufactured before April 2018.
Keeping up with Efficiency:
New gas and oil boiler systems have a programmed timer so owners can monitor their heat accurately. Gas heating is one of the most energy-efficient heating systems in the UK and new, high-efficiency boilers could significantly cut your bill, according to the Energy Saving Trust. This rating is given on a scale of 1-10, which makes it easy to see how energy efficient your new gas, oil or gas boiler will be.
Again, the current rating system is the SEDBUK, which stands for seasonal efficiency for domestic boilers in the UK. The directives give a rating of 1-10 for gas, oil and gas boilers, but new directives mean that all heating products must meet even higher energy efficiency standards and are rated on a scale of A-G. Every boiler installed in Britain must meet a certain level of energy efficiency, and this will increase even further in the years to come.
Savings from Efficiency:
You can get an A-rated condensing boiler with any type of boiler system (combi, regular, etc), including those available from most boiler manufacturers.
To understand how a new boiler could save money, you need to consider the energy that inefficient boilers waste. If your boiler is only 70% efficient and you spend £100 to heat your home, you’re wasting £30 on energy lost. However, if your newer boiler reaches an efficiency of 90%, it will only lose £10.
It is important that you have the right boiler for your home, as heating accounts for 60% of your energy consumption per year, so it is important that you make sure you have the most efficient type of system. The biggest advantage is that energy-efficient boilers and condensing boilers in particular are widely available, especially the newer models with a larger heat exchanger.
It is important to note that combi boilers are more efficient overall, but a normal boiler produces more hot water. Large families that use a lot of hot water are probably better off with a normal boiler, while smaller households that use less are better off with a combi boiler.
Combi boilers do not require a hot water cylinder and therefore require less space in your house.
Another tip is if you are thinking about installing a solar water heating system, it should be noted that many combined boilers are not compatible with a solar heating system and cannot be used effectively.
Modern combi boilers, more technically referred to as condensed high-efficiency boilers, help to reduce fuel consumption and allow households to make significant savings compared to the standard products installed just a few years ago.
Condensing boilers work by recovering waste heat that is normally released into the atmosphere. They are becoming increasingly important in the UK to meet current boiler efficiency requirements. Modern gas combi condensing boilers offer a considerably higher efficiency than a regular or combi boiler of just 5 years ago.
