Unvented Solar Heat Pump Cylinder
- Direct models are designed to be electrically heated but also incorporate a high performance solar coil to allow easy connection to a solar thermal system. Indirect cylinders are heated from a conventional oil, gas or electric boiler, but provided with a second high performance coil which is linked with a renewable heat source, like solar thermal. As a safety feature, indirect cylinders are supplied with a control/high limit thermal cut-out that operates at 90°C.
