Benefits of a JLA Commercial Wall Mounted Boiler

In the UK, the majority of boiler replacements utilise wall hung models due to their compact size, the fact they are easy to access and are simple to-use. Wall hung boilers can also be ‘cascaded’ – whereby multiple boilers work together to ensure the load is balanced, meaning that you’ll never be without heating or hot water should a fault occur.
