There are three main types of boilers in operation in the UK:

• Regular boilers, which require a separate water tank
• Combi boilers, which heat water on demand, as it enters the home
• System boilers, which have major components, such as the pump and expansion vessel, built into the boiler design

The most common fuel type for a boiler in the UK is gas, which accounts for about 60% of all domestic boilers. LPG is now also an option, as well as heat pumps and oil-fired boilers.

The Efficiency Of Old And New Boilers

These boilers all come in a range of efficiency levels which determine how much you end up paying for your heating and hot water. Energy rating agencies rate boilers on a scale from A to G, where A is the most efficient and G is the least efficient. The higher the rating, the less energy the boiler uses and the lower your carbon footprint and energy bills will be.

Boiler energy efficiency depends on several factors, including:

• Age
• Type
• Size
• Fuel
• Performance

Since 2010, all new boilers in the UK must have an A rating or above. Therefore, if you have an older boiler, your new one will be significantly more efficient, saving you money. According to the Energy Saving Trust, replacing an old G-rated boiler with a new A-rated one could save you up to £315 per year on your energy bills.
