Clyde gas condensing boilers come in two complimentary ranges – stainless steel heat exchangers and aluminium heat exchangers.

In all installations, and especially boiler replacement situations, we recommend that the boilers are hydraulically decoupled from the system by a Low Velocity Header or Plate Heat Exchanger.

Clyde Modulex is a truly modular boiler comprising 2 to 8 modules and outputs from 100 to 900 kW. It has an aluminium / magnesium / silicon alloy heat exchanger that is light, strong and resistant to corrosion. An efficiency of up to 109% net and a turn-down ratio of up to 40:1 make this a class-leading boiler – Download Datasheet
