With gas prices continuing to rise and soaring energy bills for UK households, many of you are looking at ways to reduce your energy spend each month. One of the easiest methods for reducing the amount of energy you consume is by increasing the efficiency of your gas-using appliances, none more so than your boiler.
While you might have paid it much attention previously, the efficiency of your boiler could be quietly having serious implications for your gas usage every month. An old and inefficient boiler could be costing you hundreds of pounds a year, so it’s worth checking the official efficiency rating if you haven’t yet done so.
But what are these ratings, and how do they work?
How Are Boilers Rated for Efficiency?
UK boilers are rated for efficiency using the Energy-related Products Directive (or ErP for short). It ranks boilers from A to G, with G being the least efficient. The following ErP ratings can be broken down into the following efficiency percentages:
- A – 90% and above
- B – 86% – 90%
- C – 82% – 86%
- D – 78% – 82%
- E – 74% – 78%
- F – 70% – 74%
- G – Below 70%
In recent years, boiler technology has become so advanced that the old scale is no longer fit for purpose. Some boilers manufactured today are rated A+++, producing an astonishing 100% efficiency. While they might be much more expensive up front, they can produce considerable savings over a period of 15 years or more if well-maintained.
Why Should I Pay Attention to My Boiler Efficiency Rating?
Essentially, a higher-rated boiler allows you to squeeze more heat per unit of energy you purchase, stretching your money further. If you were to compare an A+++-rated boiler with a B-rated model, you would notice an enormous saving in energy consumption to get the same output, keeping costs down.
Therefore, investing in a new energy-efficient boiler is one of the best ways to save money on your gas bill and protect yourself against ever-increasing energy costs.
My Boiler Seems Fine, Why Should I Replace It?
The number one reason for putting off a new boiler installation is cost. With your current boiler seemingly doing the job, the urge to replace it with a more energy-efficient one can seem unimportant. However, every day that your boiler uses gas inefficiently is costing you money in increased gas costs.
The mantra of “if it isn’t broke, don’t fix it” doesn’t apply to boiler replacements, especially for older, more-inefficient models. The savings you could recoup can often cover the cost of the installation and boiler unit over the lifetime of your new boiler. Plus, with flexible finance packages available from the GHS Group, a new boiler installation might not cost anywhere near as much as you might have initially thought.
