Introduction Gas boilers are a popular choice for homeowners, particularly in the United Kingdom. They’re easy to install and maintain, compact and efficient, and provide instant hot water – making them an ideal option for upgrading your existing heating system. Which is the most efficient gas boiler? best high efficiency gas boiler A condensing boiler is the most energy efficient gas boiler on the market. It can produce up to 70% efficiency, which means that it converts more than three-quarters of your fuel into heat. This makes a huge difference in terms of saving money on your gas bills and reducing CO2 emissions. A non-condensing model will only reach around 65% efficiency, at best – so if you’re serious about saving money and the environment, you should go for a condensing model instead. でも, remember that this isn’t an option for everyone because they are more expensive to buy and install than standard boilers – which would explain why most people opt for non-condensing models instead! How much does it cost to install a new high-efficiency boiler? gas boiler install cost The cost to install a new high-efficiency boiler will vary depending on the type of boiler you choose, but generally speaking it can be expected to cost between £1,000 and £6,000. It’s important to shop around for the best deal on your new boiler. There are three main types: open fire, condensing and non-condensing. Open fires are very popular as they tend to be cheaper than other types of boilers; however they’re not very efficient because they lose heat through the chimney when burning fuel at low temperatures. Condensing boilers recover heat which would otherwise go up the flue pipe when burning fuel at high temperatures, meaning that less energy is lost in this way (around 80% compared with 50% for an open […]
