The Telford Tristor Manual Fill Direct thermal store is a manual-fill, open-vented thermal storage system with a pre-plumbed mains-pressure coil. Telford states that it is particularly suited to apartment buildings because no overflow pipe is required. It is supplied in a steel case with a white finish, fully pre-plumbed and ready to install, and this listing is the Direct model in 150, 200 and 280 litre sizes.
The cylinder is supplied with a blend valve, a shock arrestor and two factory-fitted 3 kW immersion heaters. A 22 mm non-scaling ribbed heat exchanger coil is used for mains-pressure domestic hot water, with the blended hot water set to 47°C. An over-fill sensor and a domestic safety shut-off valve are included. No external feed and expansion tank is needed, stored water is topped up annually, and Telford states that the store is exempt from G3 of the Building Regulations. A 3 bar pressure reducing valve must be fitted on the incoming supply, as shown on Telford’s technical data sheet.
