As a nation, we are increasingly aware of our carbon footprint and the impact our everyday actions have on the environment. Governments have also been putting in place legislation and regulation to reduce the effect countries as a whole have on the environment and to reduce greenhouse gas emissions.
Some of the choices we make are personal ones. If you are interested in finding out about measures you can take in your home to reduce the energy you use, the Energy Saving Trust provides some useful information.
Some regulations are mandatory and enforced, sometimes without us having much knowledge about them. Two such regulations are SEDBUK and ErP energy ratings.
These two ratings relate to the efficiency of products in the home that use energy, specifically heating and hot water systems. SEDBUK stands for seasonal efficiency of domestic boilers in the UK and ErP stands for energy-related products. The ErP rating system replaced the SEDBUK standard in 2005, although the latter is still regarded as a more comprehensive standard.
The ErP rating relates to the amount of energy an appliance uses to generates energy versus how much is wasted in the process. The aim is to keep wasted energy to a minimum.
How do they affect us as consumers?
To a certain degree, these regulations don’t affect us. Responsibility for meeting the standards lies with the manufacturers prior to their products being made available for sale; however, as a responsible homeowner, it is worth knowing what they are. As an example, this knowledge means that you can check with a potential installer that they are supplying you with a boiler that meets the regulations.
These ratings are also important to us in relation to our energy bills. In most homes, more than half the energy we use goes on heating and hot water, so a more efficient boiler system should mean lower energy bills in addition to a reduction in the amount of waste carbon emitted. Given that the life of a boiler can be up to 20 years, it is possible that many homes still have a less-efficient boiler in situ.
