I have been using the solar water heater has been used for 8 years, the summer is good, but if there is no hot rain. Recently bought a new, two solar energy series method together, is a common solar water heater water tank, advanced the old, old solar water heater water into a new solar water heater, the new solar water heater outlet.Excuse me:1 this connection method is correct?2 now the problem is that this series, water supply is not normal, continuous water for 20 minutes, the water is getting smaller and smaller, to no water. There is water in the solar energy3 the best way is to link or even say, the installation of solar and even the water temperature is not the same, sometimes hot and sometimes cold, is it?
The electric auxiliary power vacuum tube solar water heater is very low, control is not good, can increase the volume of water heater a floor type chamber shape at the outlet of the solar water heater, when the temperature is low by manual electric auxiliary heating, heating power from the general 2.4/3.6/ 4.8KW.
Because of the common solar water heater is the open water tank, when the water heater two side by side when pressure is the same, if you use the series, the first solar water heater into the hot water is water with tap water, but in second when there is no water pressure, so that the second sets of solar water heaters because there is no pressure to enter the water will be greatly reduced, in order to avoid this problem, suggest the use of parallel import of water, and the water outlet with a self suction booster pump to ensure the water pressure.
The best is installed in parallel to solve the problem better, the hot water in winter, the electric water heater is the ultimate solution to the solar hot water pipe series an electric water heater, what are solved by the solar heating tube to the auxiliary heating, not only a waste of electricity, but also the heat in the day on the surface of waste ah. And actually can not reach the effect of hot water.
