Evacuated Tube Solar Water Heater System

One hundred 30 tube collectors are being installed on a farm for space heating total of 3000 tubes.

Evacuated tube solar water heater system.

Lattitude51 solar hot water collectors are being used on the largest agriculture commercial solar water heating system in north america. The split system manifolds use the same evacuated tubes combined with a heat pipe. The absorber moves energy to the copper heat pipe where energy is stored by the working fluid. Modern evacuated tube solar water heaters capture about 94 of the sun s rays.

Evacuated tube absorber layer receives incoming solar radiation. Solar water heating systems using vacuum tubes made of borosilicate glass with special coating to absorb the solar energy are called as evacuated tube collector system etc systems. Evacuated tube solar hot water system how it works. Certification information or figures calculated from those data are used.

They deliver many advantages over all other types of solar heaters. In terms of the water heater geyser price this collector is a little more expensive. Below is a table that gives a rough indication of the specifications and energy that could be expected from a solar water heating system involving some 2 m 2 of absorber area of the collector demonstrating two evacuated tube and three flat plate solar water heating systems. The vacuum tube is an assembly of two concentric borosilicate glass tubes.

A small pump circulates the water from the cylinder through the header across the top of the tubes to absorb the maximum available solar energy. If you don t use the hot water on this integrated evacuated tube solar water heater it can overheat and vent through the t p valve at 150 psi or 210 degrees. Evacuated tubes are a proven technology now widely accepted in australia all the way from consumers and plumbers right through to the federal. Evacuated tubes from endless solar provide a new level of performance and expectation in the solar water heating industry.

This solar water heater uses 1800 x 58mm high quality evacuated tubes with tri coating technology. Vacuum tube as shown in the sketch is the main component which absorbs solar energy. The working fluid boils at approx 30 c turns to vapour and rises to the heat bulb at the top. Wet tubes contain water which is directly heated by the sun and transfers the heat straight to the water in the storage tank using thermosyphon.

But there s also a decline in the cost as it gains a bigger market share.
