Our comprehensive, easy-to-install boiler cascade options boiler cascade options increase heating reliability and efficiency while providing added design flexibility. 

Spreading the total required heat output over several boilers in cascade configuration offers several advantages:

  • Greater reliability
  • Higher efficiency
  • Improved design flexibility
  • Quick and easy installation


Cascade options are available with the Quinta range and Gas 220 Ace boilers.


To make it as simple as possible to create a boiler cascade arrangement, we offer complete cascade systems for use with our wall-hung Quinta range. The small footprint of the Quinta range boilers allows an exceptionally compact cascade configuration, making it possible to install a high heat output up to 1,292kW in an extremely small area.

We offer a number of different cascade options for installing two to ten Quinta boilers, including linear and back-to back configurations, and wall-mounted or free-standing arrangements. There is the added option for multiple output configurations, combining the Quinta Pro with Quinta Ace 160 boilers, for increased design flexibility.

We also offer a cascade arrangement for the Gas 220 Ace floor standing boiler range - up to 8 boilers back to back. The Gas 220 Ace boiler is particularly suitable for use in cascade systems due to their small footprint and width of only 90cm which allows an exceptionally compact cascade configuration. For example, when using four Gas 220 Ace boilers back to back (excluding the low loss header), approximately only 1.8m x 1.5m floor footprint is required for up to 1240 kW (50/30oC).

Our boiler cascade systems are very comprehensive and use smart gas and water connection technology for easy installation. This means the hydraulic and gas system can be put together entirely without welding, using screw connections, compression connections and flanges. The individual components of the cascade systems are available for independent cascade installation.

Remeha have installed boilers on cascades for a variety of different locations, including Aspire Leisure Centre, Farley Junior school and Hexham Abbey, achieving impressive energy savings.
