The Rinnai Twin Flow System

Fully modulating, condensing central heating boiler to meet latest heating regulations SEBUK “A”. OpenTherm is the name of a non-manufacturer-dependent system of communication between the central heating boiler and room thermostats. The system consists of a communication protocol and an interface specification. OpenTherm combines simple installation techniques with high functionality and future expansion possibilities.
Weather compensation will enhance comfort and fuel efficiency.
This technology varies the heat output of the boiler according to the outdoor temperature, thus ensuring that the boiler doesn't use too much gas. Energy is saved by ensuring that maximum boiler output is hardly ever used.
2 stage frost protection to the boiler and central heating system.
