Evacuated Tube Brisbane Solar How Water Systems
Many brisbane solar hot water companies now install the new evacuated tube solar hot water system which has very high solar efficiencies. It works with a different style of collector where the collector is comprised of 40 or more very strong multi layered glass tubes .The number depends on the solar hot water system’s capacity exceptionally strong multi layered glass tubes. A vacuum exists between the inner and outer layers of the tubes to ensure captured energy is retained and not lost
The sun’s solar energy is absorbed by the array of evacuated tubes at an optimum level throughout the day. The surface of an absorptive material, which is normally copper, stainless steel and aluminium,coated on the inside of the inner tube, absorbs maximum radiation and converts it into heat. The vacuum between the inner and outer tubes ensures minimal heat loss. This is in excess of 80% of the sun’s available energy being captured by the collectors. Each tube is connected directly into a manifold mounted at the head of the solar collector.
To ensure the hot water is safe for your family to use, cold water is mixed with hot water directly from the tank via a tempering value, to ensure a water temperature of 59 degrees Celsius is maintained which is safe but comfortable for Brisbane home owners.
