Heat only boilers are also known as regular boilers or conventional boilers. Heat only boilers are designed for more significant properties.
Ideal offers 3 different heat only boilers: Logic Max Heat, Logic+ Heat, and Mexico HE.
If you are wondering what a heat-only boiler is and you are not sure if you have one, if you have a small expansion tank and sizeable cold water storage in your loft, it is likely that you already have a heat-only boiler.
In the guide below, we will discuss the critical information about the three individual Heat Only Boilers:
The gas Logic Max boiler is A-rated for efficiency and is part of the Ideal award-winning Logic+ range and uses the Ideal system filter to lengthen the life of the boiler.
The Logic Max boiler is available in the following output flow rates -12kW, 15kW, 18kW, 24kW, and 30kW.
The optional outputs mean the boiler range is suitable for two-bedroom homes, four-bed homes, and five-plus with multiple bathrooms. Your Gas Safe engineer will decide on which output you need, and the price will vary depending on the output size you need.
The prices vary between £870 and £1,195, including VAT but not installation fees, which will be an extra cost.
