Description
The TSDC 210 Litre Vented Thermal Store – Direct Single Coil is designed for use with gas or oil boilers to deliver fast, safe and reliable mains‑pressure hot water throughout the home. As a direct‑pattern cylinder without an integrated feed and expansion tank, it must 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 to maintain store temperature, controlled by the store thermostat
-
One for the heating circuit, controlled by the room thermostat and heating programmer

Safe open‑vented thermal store
The thermal store holds central‑heating water within the tank. Domestic hot water is produced at mains pressure via a powerful internal coil, delivering excellent shower performance and fast bath filling — with no pump required on the hot‑water side.
This model is a modern replacement for the Boilermate and Albion Mainsflow Direct systems.
Acting as a buffer, the thermal store reduces boiler cycling, improves efficiency and ensures rapid radiator warm‑up. These low‑maintenance, pre‑plumbed units deliver flow rates of up to 30 L/min and, when paired with a suitable gas, oil or LPG boiler, are ideal for medium to larger properties. The bottom coil must be pumped.
Each unit features a smart, wipe‑clean appliance‑grade finish and 60 mm foam‑injected insulation for maximum efficiency. 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.
