Nero Triple Coil

The Warmflow triple coil hot water cylinders feature a total of three 22mm heat exchanger coils. This flexibility means that, for example, the cylinder might be heated by a solar thermal system via the renewable coil, a wood pellet boiler supplying the primary coil and a back-up oil or gas boiler on the tertiary coil.

Seamless welding & duplex stainless steel design our cylinders are supplied with all the necessary parts for a quick, easy & professional installation. We supply only the highest quality components from recognised, market-leading suppliers.

Excellent product and service
