The models feature large dedicated renewable volumes, making them suitable for use with solar thermal systems in line with the recommendations in the Domestic Building Services Compliance Guide. The renewable coil (the lower of the two coils) has a large surface area to maximise the use of available low grade heat from a renewable resource. The immersion heater and cylinder thermostats for both coils are supplied. Twin Coil models (200 litres & above) feature a dedicated 22mm connection for use with a secondary return (pumped circulation).
