OSO Solarcyl RI SD

  - Providing free solar heated hot water

The Solarcyl is a purpose-designed solar ready unvented cylinder, providing high solar input from the large heating coil and substantial dedicated solar volume. The Solarcyl has back-up heating with twin electric immersion heaters. High performance fully flooded design, with expansion vessel supplied with the cylinder.

The Solarcyl is able to provide up to 60% of annual domestic hot water requirements from free solar energy captured by roof panel collectors. Solar thermal installations using the Solarcyl can be eligible for government backed Renewable Heat Incentive.

Solarcyl is ideal for connection with all types of solar collectors, including the OSO SolEnergi collectors and differential controller to complete a high performance system.

 

The positioning and size of the coil in the Solarcyl maximizes the use of available solar energy. A second electric immersion heater is fitted in the top half of the cylinder for boosting temperature when solar energy is low. The fully flooded design offers a superior hot water performance when solar gain is low, and the separate, external expansion vessel is supplied with wall bracket and flexible hose.

Key advantages:

  • Specifically designed for solar collectors with large heating coil.
  • Twin immersion heaters for back-up heating when solar gain is low.
  • OSO ECO Foam insulation and 25 year guarantee.

Technical Specifications
Quick Facts
Choose volume

Solarcyl is available in 2 different volumes, estimated to be suitable for the no. of people designated in the table below. The table shows suitable volumes based on experience from average hot water usage in a normal household. If the household has a large hotwater usage, for instance due to large bathtubs, steamshowers etc., one should choose higher volume than designated in the table. Hotwater capacity is calculated by instant tapping at 40°C. At 40°C a normal shower uses approx. 60 l., bathtubs 180 l. and bubblebaths 400 l. Capacity is also dependant upon solar collector size and performance.
