Evacuated Tube Solar Heaters FAQ I

FAQ I How does a water evacuated tubes? Solar radiation is converted into useful heat pipes evacuated and sent to the water, so warm. The vacuum tubes removes the heat losses to the environment. The insulated tank (water heater) keeps the hot water 24 hours a day. Residential systems work by thermosiphon effect depending on the type of cold water supply exists in the home or place of installation are two models. System for elevated tank thermosyphon system is used when there is an elevated tank to pressurize the water system of the house, this tank must be elevated at a height above the roof level of 80 cm to 150cm.

If the water tank is below this level, the team will not have enough pressure to operate and does not heat the water. If the water tank is above this level will create greater pressures to supporting the team and must incorporate an automatic float. Tank or solar hot water tank has a series of holes along it, where you place the evacuated tubes. The tube when exposed to sunlight reaches temperatures above one hundred degrees Celsius, the heat is transferred to water containing the tube inside the hot water loses density and weight so it tends to rise naturally to thermo tank, while cold water tends to fall within the evacuated tubes, as it has greater density and weight. Water movement is performed without pump and requires no electrical or mechanical components, this makes the equipment more reliable, easier to maintain and more durable.
