Clearly Solar

Straightforward Solar Thermal Solution
Designed specifically for use on UK homes, Clearly Solar has everything you need to look for in a flat plate solar thermal solution. Glow-worm’s Clearly Solar system delivers between 50 and 60% of your domestic hot water every year. In the summertime it can be as high as 100% which means that your boiler may never have to fire up, saving energy and money.

 
Robust and subtle design
Clearly Solar comes in a really simple pack solution ensuring that you have everything you need for your solar thermal installation, with total compatibility and simplicity. The flat plate collectors are made from black anodised aluminium which makes them hard wearing, robust and very subtle, neatly fitting into or onto your roof. Alternatively, if the inclination or aspect of your roof is not perfectly suited for a solar installation, Clearly Solar can also be installed on A-frames which are extremely easy to construct and site on a flat roof or in a garden.

Total compatibility
Clearly Solar is a pressurised system, meaning that it is completely full of heat transfer fluid and sealed from
the atmosphere (a similar concept to a sealed heating system). As with all Solar Thermal systems, you will still require a secondary heat source to provide your central heating. Clearly Solar is fully compatible with all new and existing open vent and sealed system boilers (including the complete Glow-worm range) or immersion heaters in non-gas areas.

Solar Panel

The Glow-worm Clearly Solar Flat Plate Collectors (part of the Clearly Solar system) give high efficiencies from a large absorber area of 2.35m², robust construction from toughened glass and laser welding, whilst the slim line frame gives it a total footprint of just 2.51m² and at 38kg it is one of the lightest flat plates on the market.

 

Construction:
• Black anodised aluminium frame
• Serpentine absorber made of copper
• Solar glass thickness 3.2mm (tough and resistant to vandalism)
• Absorber laser welded and not soldered, suitable for high temperature
• High selective absorber coating
• 10 year warranty on Clearly Solar Collector

Dimensions:
• Dimensions 1.23 x 2.03m
• Gross collector area 2.51m²
• Absorber surface areas 2.35m²
• Low flat plate weight only 38kg
• Total depth 80mm achieving low protrusion

Performance:
• Leading performance flat plate collector
• Light transmission 91%
• Solar radiation absorption 95%
• Solar radiation emission 5%
• Shutdown temperature 210ºC
• 40mm insulation for improved efficiency

Fixing:
• Horizontal and vertical collectors available
• Mounting accessories for pitched roofs
  (On roof and In roof)
• A-frame for flat roofs  

Clearly Solar Cylinder

Unvented, stainless steel and narrow enough to fit through any standard airing cupboard door, the Flurocyl twin coil cylinder ensures that every last bit of the suns energy is used and a high volume of domestic hot water is provided all year round.

  

Clearly Solar twin coil cylinder Features:

• Twin coil cylinder fully compatible with all open vent and sealed systems, including the full range of
   Glow-worm boilers
• Available in 200, 250 and 300 litres
• High grade stainless steel cylinder with laser welded seams
• Insulation meets CHeSS best practice (loss as low as 1.9kWh)
• 25 year warranty on cylinder shell
• 554mm width for flexible siting
• 3kW immersion heater as standard
• 3 thermal cut outs (boiler, immersion and solar)
• Supplied with a carrying handle for ease of transportation

Clearly Solar Controller

The Clearly Solar Controller is the real brains of the operation, simple to use with a boiler domestic hot water programmer and solar gain display to show how much energy has been collected from the sun since the system began operating. Intelligent functionality holds off the boiler whenever there is solar gain to be had making fossil fuel usage as low as possible.

 

Clearly Solar Controller Features:

• Differential temperature control
• East / West system control (additional collector sensor and pump station connection)
• Solar gain display
• Temperature sensors
• Two channels (solar & boiler)
• Programmable boiler & auxilary channels
• Easy wiring connections
• Solar gain modulation
• Boiler heating delay function (to maximise solar yield and save you money)

 

Solar Pump Station

The Clearly Solar Pump Station pumps the solar fluid from the flat plate collector to the cylinder and back again. Its compact design fits easily on the wall in the house or loft. The Three speed pump enables you to match the flow rate of the system to a wide range of properties.

Because heat naturally rises the pump station is fitted with 2 check valves which stop circulation of the solar fluid when the pump is not running, forcing the heat to stay in the cylinder rather than transferring back into the collector, increasing system efficiency.

Clearly Solar Pump Station Features:

• 6m head pump
• Integrated flow meter
• Two isolation valves
• Two non-return valves
• Two temperature gauges
• Pressure gauge
• Pressure relief valve
• Expansion vessel connection
• Integrated flow adjuster and meter
