Slimline Indirect Heat Pump
Our space-saving slimline range, that come with a 25-year cylinder warranty from the manufacturer, available in 120-200L capacities, and are perfect for retrofit installations in narrower airing cupboards. Slimline indirect heat pump cylinders are manufactured with duplex stainless steel and come equipped with a 2m2 or 1.6m2 316L-grade heating coil (capacity dependent). These coils are made from wide-diameter corrugated tubing to encourage turbulent flow in the heat exchange process for maximum performance, and quicker recovery times.
All heating coils supplied with these cylinders come with 1” BSP connections, for suitability with 28mm copper pipe, reducing pressure drop at high flowrates, enabling a greater COP from your chosen air source or ground source heat pumps. Additionally, all cylinders come provided with a 12mm probe pocket for temperature monitoring either through the heat pump, or via a cloud-based controller.
An immersion heater is placed beneath the heating coil at the bottom of the cylinder. This can be connected to a solar PV diverter to power your cylinder entirely via renewable technologies but should primarily be used once per week for a 60-65°C pasteurisation cycle for at least 1 hour to avoid any risk of legionella bacteria growth.
These units come provided with a G3 unvented compliance kit (3 bar/6 bar inlet control set, 7 bar 90°C temperature and pressure relief valve and associated insulation cover, 15mm x 22mm tundish), a suitably sized expansion vessel, 28mm 2-port zone valve, and a high-lit cut-out thermostat.
All installations should be made in accordance with building regulations, as well as the terms detailed in our installation manual, and should be carried out by a qualified professional.
