Twin Coil Unvented
Our Twin Coil models have all the features and benefits of the Indirect models but come with an additional coil for use with a renewable heat source, or an additional boiler.
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 2010.
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 cylinder thermostats for both coils are factory-fitted and an immersion heater is supplied for back-up. All Twin Coil models feature a dedicated 22mm connection for use with a secondary return (pumped circulation).Purchase Info
