Twin Coil Cylinder

Our Twin Coil models have all the features and benefits of the Indirect models but come with an additional coil for use with a solar 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.

Our Twin Coil models have all the features and benefits of the Indirect cylinder models with thermostats for both coils factory-fitted and an immersion heater supplied for back-up. All Twin Coil models feature a dedicated 22mm connection for use with a secondary return (pumped circulation). Our new range or heat pump cylinders available in volumes of 250ltr & 300ltr have been specifically designed to work alongside our Zeno range of air source and ground source heat pumps
