Stelflow Twin Solar150 | 180 | 210 | 250 | 300 litres
The new standard in unvented hot water solutions for residential dwellings.
Joule Stelflow unvented cylinders features a dedicated high performance solar coil, transferring the maximum amount of heat from the solar circuit to the stored water. The indirect cylinders are heated by a conventional boiler (either gas or oil) through a second high performance coil and specifically designed for solar thermal applications. Fitted with a high efficiency coil to maximise the heat transfer from the solar input.
Stelflow cylinders have carefully been constructed using quality components and has been designed with performance in mind. Using our many years of involvement within the hot water industry and our knowledge of bringing unvented cylinders to the market we have created a new standard in unvented water storage.
