Description
The TSDC 140 Litre Advance Thermal Store is designed for use with gas or oil boilers to deliver fast, safe and reliable mains‑pressure hot water throughout the home. The direct‑pattern (TSDC) cylinder does not include an integrated feed and expansion tank and must therefore be supplied from a remote F&E tank positioned above the highest point of the radiator circuit.
The system requires two pumps:
-
One for the boiler, maintaining store temperature via the store thermostat
-
One for the heating circuit, controlled by the room thermostat and heating programmer

Constructed from stainless steel, the cylinders are lightweight, durable and built for long service life. All models are manufactured in the UK and comply with the HWA Thermal Store Specification and Building Regulations.
