This unique combination is able to provide the user with hot water immediately at the outlet of the appliance
temperatures at both extremely low flow rates or when several taps are opened together.
The TSS@ is a 5 litres, independently controlled mini unvented storage cylinder, powered by a 3 kW coil. It works in conjunction
with the Chaffoteaux et Maury low pressure instantaneous domestic hot water system.
The CALYDRA, as well as providing hot water, provides central heating. The boiler is designed for sealed systems only. A two
speed circulating pump, diverter valve, expansion vessel as well as a pressure gauge and safety valve are included within the
boiler.
The CALYDRA provides the advantages of mains pressure hot water
