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
