Evacuated Tube Collector Based Solar Water Heating Systems

30 evacuated tube collector.

Evacuated tube collector based solar water heating systems.

Evacuated tube absorber layer receives incoming solar radiation. Apricus etc evacuated tube solar collectors convert energy from the sun into usable heat in a solar water heating system. Modern evacuated tube solar water heaters capture about 94 of the sun s rays. This type of system can replace or supplement electric or gas powered hot water heaters for substantial energy savings and reduction in co 2 emissions.

Evacuated tube solar collectors involve a row of glass envelopes tubes emptied of air which creates a vacuum and makes for excellent insulation. The working fluid boils at approx 30 c turns to vapour and rises to the heat bulb at the top. The absorber moves energy to the copper heat pipe where energy is stored by the working fluid. A heat transfer fluid such as water or glycol circulated through a flat plate or an evacuated tube solar collector collects solar radiation as heat to be used to heat water for household use.

Solar water heater should be service cleaned after 2 year. Whether you have an oil or gas condensing boiler a heat pump or a heating system for wood you will be able to use it in conjunction with our evacuated tube solar collectors. Flat plate and evacuated tube solar collectors are mainly used to collect heat for space heating domestic hot water or cooling with an absorption chiller in contrast to solar hot water panels they use a circulating fluid to displace heat to a separated reservoir. Sunmaxx evacuated tube solar collectors are now srcc solar keymark certified and now apply for all federal state solar tax credits and other incentives.

Evacuated tube solar hot water system how it works. One hundred 30 tube collectors are being installed on a farm for space heating total of 3000 tubes. Copper rods inside the tubes are connected to a massive copper tube inside the enclosed header through which water flows. Silicon solar offers pre packaged solar hot water heating systems for both the do it yourself customer and the professional installer.

The following figures demonstrate efficiencies of collectors when heating water from ambient temperature to 75 degrees celsius data provided by hills solar. These systems are designed to provide hot water year round and they can work in combination with our other heating solutions. Every year there is 20 efficiency loss. This energy can be used for domestic and commercial hot water heating pool heating space heating or even air conditioning.

The results below speak for themselves on the improved efficiency of evacuated tube technology over flat plate collector solar hot water systems. Lattitude51 solar hot water collectors are being used on the largest agriculture commercial solar water heating system in north america.
