Our Expert's Opinion
"High efficiency corrugated coil maximises heat transfer to the cylinder of water"Gledhill StainlessLite Plus Heat Pump 400L Unvented Cylinder
The Gledhill StainlessLite Plus Heat Pump 400 litre is an unvented mains-pressure hot water cylinder engineered for use with air source (ASHP) or ground source (GSHP) heat pump systems. Built from high-grade duplex stainless steel with a large-surface primary coil optimised for the low flow temperatures typical of heat pump operation (typically 45-55°C), it delivers high-flow mains-pressure hot water to multiple outlets without a cold water storage tank. A 3kW backup immersion heater is fitted for boost or emergency backup.
Designed as a complete, Building Regulations G3-ready package for heat pump installations. Supplied with an internal expansion vessel (no separate external vessel required), the combination inlet group (pressure-reducing valve, strainer, check valve and expansion relief valve), temperature and pressure relief valve, and tundish. Backed by Gledhill's 25-year cylinder guarantee.
