VIESSMANN VITOCAL ASHP CYL SLIM 170L

The Viessmann Vitocal ASHP Cyl Slim 170L is a space-saving domestic hot water cylinder designed for integration with air source heat pump systems. Its slimline form makes it ideal for plant rooms and cupboards where floor area is limited, while providing dependable hot water for everyday household use.

Engineered to work efficiently with low flow temperatures typical of heat pumps, the cylinder features an indirect coil to transfer heat effectively from the primary circuit. High-quality factory-applied insulation helps reduce standing heat loss, supporting overall system efficiency. The unit is designed for straightforward integration with Viessmann Vitocal heat pumps and can be connected to other ASHP systems via standard fittings.

Suitable for mains-pressure domestic hot water when installed as part of an unvented system by a qualified installer, the cylinder includes provisions for control sensors and is laid out for tidy, accessible pipework. Model identification: Vitocal ASHP Cyl Slim 170L, product code 794943.
