Vitocell 200-V/B

With a Vitodens system boiler the cylinder is controlled by the built-in diverter valve and the optional tank sensor and comes supplied with all cold and hot Water Controls and a two-port valve for domestic hot water. The Single coil cylinders are available in seven sizes, from 90 litres to 300 litres.
Manufactured from the very latest high specification Duplex Stainless Steel to resist all forms of corrosion, the cylinders are nevertheless light and easy to handle and insulated with at least 50 mm of polyurethane foam. This results in astonishingly low levels of heat loss and a performance greater than CHESS requirements.
All cylinders are also provided with an auxiliary back up 3 kW electric immersion heater. The operating thermostat and energy cut-out are for use with non-Viessmann boilers or traditional 'S' or 'Y' plan systems*. The immersion heater is fitted at the front for easy access and designed for use in un-vented installations, and it contains an additional safety overheat thermostat.
