OSO Solarcyl Twin Coil RI TC

The Solarcyl Twin Coil is a purpose-designed unvented cylinder for combining alternative heat sources. A low temperature heat source in combination with a high temperature heat source is the optimal combination. The Solarcyl Twin Coil has an electric immersion heater as backup in the lower part of the cylinder. High performance fully flooded design, with expansion vessel supplied with the cylinder.

The upper heating coil on the Solarcyl Twin Coil is somewhat smaller than the lower. Ideally, the Solarcyl Twin Coil utilizes a low temperature heat source, such as solar, in the lower coil, while using a boiler in the upper coil. This combination will provide hot water without the use of electricity. Other combinations are also possible. Solar or heat pump installations using the Solarcyl Twin Coil can be eligible for government backed Renewable Heat Incentive.

The Twin coil can be used with inverter technology heat pumps up to 12 kW, or the equivalent in solar collectors, for a high performance system.

The positioning and size of the coils in the Solarcyl Twin Coil maximizes the use of the alternative heat source, whilst supplying plenty high temperature hot water. An electric immersion heater is fitted in the bottom of the cylinder for back-up heating. The fully flooded design offers a superior hot water performance, and the separate external expansion vessel is supplied with wall bracket and flexible hose.

Key advantages:

• Specifically designed for low- and high temperature heat sources in combination.
• Immersion heater for electric back-up heating when necessary.
• OSO ECO Foam insulation and 25 year guarantee.
