Greater solar collector for more hours of the day by apricus logo

Our solar hot water systems are designed with evacuated tube collectors that passively track the sun for more hours of the day to provide greater solar collection.

If you need to replace your hot water heater or you are buying or renovating your home, why not upgrade to solar? We will connect you with your local Apricus Solar Hot Water System agent to recommend the best system for your property based on the climate you live in, the water quality and your water usage. We have solar hot water system agents Australia wide- Sydney, Melbourne, Brisbane, Adelaide, Canberra, Darwin, Perth.

It’s important to ensure you select the right solar hot water system or solar hot water heater to meet your homes requirements. If your storage tank is too small you risk running out of water or your tank is larger than what your household needs, energy will be wasted in storing excess hot water. Talk with an Apricus Solar Hot Water System specialist who can advise you on the right size solar hot water system or heater to meet your family requirements.

Apricus are specialists in designing innovative, solar hot water heating systems for residential and large-scale commercial properties. We help property owners who care about their environmental footprint enjoy sustainable savings on their energy bills.

Evacuated Tube Solar Hot Water System- How it works.

Apricus Solar Collector 1The Apricus solar collector includes four main components.

  1. Evacuated Tube
  • Absorbs solar energy and converts it to usable heat. A vacuum between the two glass layers insulates against heat loss.
  • The Heat Transfer Fin helps to transfer heat to the Heat Pipe.
  • The silicon rubber caps at the end of the tube protect the tube and are UV resistant.
  1. Heat Pipe
  •     Copper vacuum pipe that transfers the heat from within the evacuated tube up to the manifold.
  1. Manifold
  • Insulated box containing the copper header pipe. The header is a pair of contoured copper pipes with dry connect sockets that the heat pipes plug into.
  • The manifold casing is made of a strong but lightweight aluminium alloy that is folded to form a strong protective enclosure. The casing is finished with matte black PVDF coating that is UV stabilised for long- term colour fastness.
  • Glass wool insulation is “baked like a cake” to form a complete structural shell around the header pipe. This design minimises the amount of metal used in the casing, reducing embodied CO2, and making it very lightweight. The lightness of the manifold box is a feature that installers value when carrying onto the roof.
  1. Mounting Frame
  •     Strong and easy to install with a range of attachment options
  •     Our manifold is significantly stronger than competitor products with high tensile anodized aluminium mounting frame and 316 (marine grade) stainless steel fasteners and hardware.  Only two of new front tracks are required even in high wind load regions.

Evacuated Tube Solar Hot Water System- Designed for the Australian climate

As a system that operates in the outdoors, this means all the components of the collector must be able to withstand all conditions – from freezing point – to the extreme heat and UV radiation of desert locations.

Apricus collectors are designed with this is mind.   One way this is managed is the use of silicone rubber instead of plastics for the tube caps, rubber header seals and manifold covers. Silicone rubber is extremely durable, staying flexible in a wide temperature range.  It is able to withstand over 200oC / 392oF and is extremely resistance to damage from UV light.

Superior design

Evacuated tube solar collectors convert energy from the sun.  They have a vacuum between two glass layers and work similar to a thermos flask allowing it to retain up to 95% of the solar energy they capture!

This means in colder climates, and during the winter months, heat is retained and not lost into the atmosphere. The collectors are rated to handle frost and down to -15°C temperatures – without the use of glycol which dramatically reduces maintenance of the system.

The evacuated tube and heat pipe are assembled in a patented format that is different to any other product on the market.

Rather than a centrally located heat pipe with heat transfer fins radiating out to the glass wall, the heat pipe is positioned directly against the glass wall, where the sun strikes.

The aluminium heat transfer fin is tightly held against the top inner wall of the evacuated tube and heat pipe with a set of spring clips.

This is a key design feature as over time, with exposure to high temperature, the aluminium will soften.

The spring clips guarantee long term tight contact with the glass wall and heat pipe, which is essential for optimal performance.
