Stainless-steel cylinders have 25-year guarantee

A range of stainless-steel hot-water cylinders from Férroli comprises six sizes with capacities from 150 to 500 litres. They are unvented, so there is no internal expansion bubble to maintain. They have a 25-year guarantee and require no anode, making them easy to install and long-lasting. These cylinders come as a complete kit ready for installing. The full set of components includes inlet-control facilities with a pressure-reducing valve set to 3.0 bar, check valve, and a filter and expansion valve set to 6.0 bar. They also include a cylinder thermostat, energy cut-out valve, 22 mm motorised valve, 3 kW immersion heater, temperature and pressure gauges, plus an external expansion facility. Maximum direct water flows are 40 to 75 l/min. Continuous outputs range from 567 to 1375 l/h. The larger 400 and 500 litres models have a second return for faster heating.
