Remeha Gas 320/620 Ace

Engineered for reliable and efficient performance, the Remeha Gas 320/620 Ace floor-standing boiler is designed with new and old building plant rooms in mind.

 

It’s a compact boiler, easy to install and easy to maintain. The Remeha Gas 320/620 Ace has the capacity to be installed side to side, which provides flexibility in floor design.

 

It also has an optional secondary return feature that makes this boiler particularly suitable with heating technologies that use low-grade heat, such as heat pumps or underfloor heating circuits.
