So, you might want to choose a boiler than fits the decor of your home despite there being far more pressing considerations, even that’s possible.

But if you are unsure where your priorities should lie when making your new boiler decision, perhaps more information will help.


A budget for yearly maintenance is a crucial element to keep your system at optimal efficiency but on the whole, when you are replacing a system, you’ll be thinking about the price of the boiler.  Costs vary depending on the efficiency, size and brand and model. 

  • Electric boilers costing anywhere between £1100 to £4000 may be used for homes without gas network
  • Depending on its strength, new gas boilers may be priced within the range of £700 to £2000
  • Depending on size and type, Baxi Boilers range from  £700 to £1300
  • Depending on your house’s built-in systems, another combi boiler may cost from £650 to £1500
  • Oil boiler systems are costly just as much as they are efficient. For these, you should be mentally prepared with a range from £1180 to £2700

 Do your research

There are some key considerations you have to take into account while acquiring your knowledge on the different types and makes of boiler.

 ErP rating: This rating criteria differentiates energy efficiency levels from the lowest (labeled with the letter G) to A+++, which is the highest. This is a replacement for the UK’s SEDBUK (Seasonal Efficiency of Domestic Boilers UK) rating system set for energy-based items. 

 ErP efficiency: Using ratings of A and a 100 % for defining high levels of efficiency, this measure helps calculate how much fuel is used by the boilers for energy conversion and how much or how less wastage is produced in the process. Since April 2018, boilers in the UK are required to be 92% efficient however, aim for 100% or an A graded super efficient boiler.

 Decibels: Decibels levels of up to 80db are not considered dangerous for people. But a 50db is ideal for the least amount of sound pollution and peace in your home environment. 

Kilowatts: The kilowatt is a measure of energy. In this case, particularly, it measures the amount of energy required by a boiler to heat your house. With larger homes requiring up to 35kw and smaller ones only up to 24kw, this is a reliable measurement of energy use. 

Nitrogen oxides: emission of harmful gases like nitrogen oxide must be kept a close check on. Under 30 is an ideal. 35 or over is worrying but can be controlled. Over 40 however, is alarming and could mean there are problems.  This statistic figure is measured in milligrams per kilowatt. 

 Size: the perfect boiler choice greatly depends on the availability of space as a few require huge tanks. If you have space and size constraints, you need to concentrate on choosing a combi or electric boiler. 

It might look as if there is a lot to consider when deciding on which new boiler to buy. Just keep reminding yourself you need an energy efficient way to heat your home and make hot water.

Concentrate your efforts in that direction and the rest, such has how loud it will be, will effortlessly fall into place. Furthermore, you can check to gather more information about buying and installing an energy-efficient boiler.
