Apricus collectors can perform well even in freezing conditions thanks to thick glass wool insulation and the vacuum insulated evacuated tubes. This is in contrast to flat plate collectors that perform poorly in cold conditions.
Apricus collectors are designed with a round absorber surface that can passively track the sun throughout the day. This means more stable heat output throughout the day, not just at midday. The tubes are also spaced close together to minimise light loss between the tubes, and eliminate the need for a reflective panel.
Apricus heat pipes are designed to withstand freezing without damage, which means that the collector can operate in very cold regions. Click Here to download Fact Sheet and Pricelist .
How It Works
Step 1. Solar Absorption
Solar radiation is absorbed by the evacuated tubes and converted into heat.
Step 2. Solar Heat Transfer
Heat pipes conduct the heat from within the solar tube up to the header
Step 3. Solar Energy Storage
Water is circulated through the header via intermittent pump cycling. Each time the water circulates through the header the temperatures is raised by a small amount. Throughout the day, the water in the storage tank is gradually heated. The temperature the water in the tank will reach will depend upon the amount of solar radiation, the size of the tank and the hot water usage throughout the day.
