The Thermal Store 320 L supplies hot water with a high-pressure mixing valve, direct from your mains water supply. Placement is very versatile, as all it needs is access to the cold mains water and an overflow outlet for combination units, or a header tank for cylinder units. Installation is straightforward with no need for an unvented certificate. This eliminates many of the constraints of traditional vented units while providing greater flexibility. The unit also comes equipped with a port for immersion heaters (two on the direct models), a drain valve, and an expansion vessel. Warranty: 2 years.
