Main Eco Compact 18kW Regular Boiler

It is important to remember, that when purchasing a regular boiler, you will need to have an additional hot water cylinder installed, as well as a cold-water feed and an expansion tank. For this reason, we don’t recommend regular boilers for homes with limited space.

On the other hand, if space is not an issue in your home and you have a high demand for instant hot water, then a regular boiler could be perfect for you. This is because regular boiler systems can store hot water ready for when you need it.

With that said, if you are looking to purchase a new or replacement Main Eco Compact 18kW regular boiler, then this model is most suitable for homes with around 10-15 radiators and moderate demand for instant hot water, thanks to its central heating output of 19kW. Smaller homes with lesser demand for central heating and instant hot water would benefit more from the 15kW model. On the other hand, we recommend 24kW or 30kW model for larger homes. 

The Main Eco Compact 18kW regular gas boiler has an efficiency rating of 89%, making it a B-Rated boiler. As a result of this efficiency rating, you may be paying over the odds for your energy bills. If you currently have this regular boiler installed in your home, we recommend that you upgrade to save money on your monthly costs.
