By combining their modern highly efficient low water content fanned flue combination boiler concept and the brand new
TSS®“Temperature Stabilised System”, Chaffoteaux et Maury have created a whole new concept.
Calydra comfort
This unique combination is able to provide the user with hot water immediately at the outlet of the appliance and stable
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 comfort, as well as providing hot water, provides central heating. The boiler is designed for sealed systems only.
A one speed circulating pump, diverter valve, expansion vessel as well as a pressure gauge and safety valve are included
within the boiler.
The Calydra comfort provides the advantages of mains pressure hot water to taps and showers. Supplied directly from the
main water supply the Calydra comfort does not need a separate feed cistern or vent pipe in the loft space.
The Calydra comfort has been tested and approved by the WRc as meeting with the requirements of the water by-laws
scheme.
The boiler has been tested and approved to carry the CE mark.
The Calydra comfort can be installed with the standard horizontal flue, raised horizontal, concentric vertical, twin pipe flue or
seduct arrangements. Adapters, bends and other accessories are available on request.
The boiler is packed in TWO cartons:
1. The boiler.
2. The flue assembly and fixing kit.
