Attractive in appearance with superb heat loss characteristics, Advance Heat Pump Cylinders are supplied with fitted T&P valve, immersion heater for thermal disinfection, dual thermostat with control and high limit plus full G3 kit.


Advance Appliances has spent many years developing and refining the range of cylinders to work with most heat pumps. A lot of the work was carried out with manufacturers of heat pumps to provide the optimum synthesis of technologies. The coils are not only much larger in surface area than standard cylinders; they are configured for low resistance, high capacity and maximum temperature drop. Their position within the cylinder has been chosen to give the best performance. This design is critical, and will get the very best heat up performance from heat pump inputs. Coil outputs are measured using typical heat pump temperatures and flow rates. For faster flow rates our range of HPL (single coil) and HPSL (twin coil) tanks offer even lower resistance. All cylinders are supplied with an appropriate G3 kit and meet Part L and Part G of the Building regulations. A 25 year guarantee gives specifiers and installers reassurance that they are choosing market leading technology and manufacturing. All cylinders are made in the UK.


Also supplied: Control and High Limit Thermostat, 1 x 2 Port Motorised Valve*, 1 x 3kw Immersion Heater, Tun Dish and Installation Manual. The units meet current building regulations, are manufactured in the UK and guaranteed for 25 years (components 2 years). * with Twin Coil only.
