Remeha Gas 210 Ace - Floor Standing Boilers

Floor Standing Boilers

Gas 210 Ace

A compact, lightweight structure makes the Gas 210 Ace floor standing boiler quick and easy to install. It has the capacity to be installed back-to-back, which provides added flexibility in space-saving design. The optional secondary return feature makes this boiler particularly suitable with heating technologies that use low-grade heat, such as heat pumps or underfloor circuits.
