First,there is water in the water heater tank, but not filled with water can be at any time, just run out of hot water, it is timely replenishment. If there is more than 15 minutes of dry and air drying, do not add water, should be arranged at night or the next morning .So as not to damage the temperature difference is too large vacuum tube;Secondly,Bath water temperature should be to prevent exce...

There are three reasons.Firstly,the control system is failing;secondly,the solar water tank’s temperature is over 70 degrees;thirdly,the electric heating pipe was broken.And there are three methods to deal.Firstly,,repair or replace the controller;secondly,electric heating pre-set self-protection;thirdly,replace the electric heating pipe.

The difference of the solar water tank and water at the outlet height is less than 3 meters.You can increase the diameter of the water pipe or install booster pump.

There are eight reasons.Firstly, the mounting angle deviation is too large;secondly,there are obstruction near the collector plate;thirdly,there are much dust on the vacuums’ surface;fourthly,poor water quality leads to the accumulation of sludge within the vacuum tube;fifthly,you obeyed to the requirements to install a necessary check valve,resulting in the loss of hot water;sixth,the bad weather...

There are four reasons.Firstly,there isn’t water in the water tank;secondly,the water pipe has freezed or jamed;thirdly,the sewer has a phenomenon of anti slope;fourthly,control system was failing.And there are four methods to deal with these questions.Firstly,inject water again;secondly,dredge the pipes and replace the valve;thirdly,correct the layout of pipes.You can try to choose one water mixi...

There are five reasons.Firstly,municipal water is too low or cut off the water supply;secondly,the water pipe has freezed or ruptured;thirdly,the vacuum tube was damaged;fourthly,the water tank is leaking;fifthly,control instrument is failed or electromagnetic valve was broken down.Of course,there are five methods to deal with them.Firstly,feed water in the water trough;secondly,you should dredge ...
