Product Description:

good water quality
It use tap water directly, live water but not sedimentary water.

pressure endurance
The thick of coil is 0.8mm, which can withstand 6-12 bar.

working automatically
A feed tank on the top, it will supply water automatically. What you need is just to open tap and have a wash.

no scale, high efficiency
Water in the tank wouldn't be used just to heat the coil, the water in the tank will keep hot and no scale. The vacuum tubes will be kept clean, and system has a higher efficiency than normal system.

simple structure
Total 3 valves in whole system only, very simple and safety, maintenance free.

anti-freezing
Because of all hot water in main tank, the feed tank won't be frozen. It can be working well in -10deg.C. - good performance in rainy & cloudy days
When tap water comes in and out, it will be just 3deg.C less than water in tank. Viz. if 90deg.C in tank, the outlet water will be at 87deg.C after exchanging.
If tank water is 90deg.C, and you catch rainy days, no problem, if you use 50L 40deg.C water per day, you can keep getting such hot water for 15 days!!
The electric heater is only backup, we don't use it anytime practically, except in winter.

more capacity
Because the water in tank doesn't be used, in fact the circulation is not only water in the tank but also water in the tube. So for example 300L, actually it has 400L in whole system.

Q:Is the solar water heater automatically supplied by temperature?
Features: automatic constant temperature water, replenishment, Sheung Shui, water temperature and water level digital color display, using humanized design, with low pressure water level, preset mode, timing control, manual control, automatic anti overflow, high temperature protection and other main functions, the use of more convenient, more secure and more practical.First, the main technical indicators1, the use of power supply: 220VAC power consumption:
Q:Can you install a solar water heater on the first floor
Tolerable。 Wall mounted. There are two kinds of wall mounted solar water heater, the water tank is placed in the balcony, the collector is placed on the south balcony of the building. The utility model relates to a solar energy water heater with the integration of heat storage and heat collection. As shown in the following figure
Q:How to defrost the solar water heater
A better way is to pay close attention to the weather, when the temperature is below zero, it will open the antifreeze device, the solar water heater to preheat protection without worrying about the problem of electricity consumption. Especially in the northern cold region, when the temperature is always at minus, it is necessary to open the heating antifreeze device. Other areas if the night temperature is relatively low, you can start in the evening antifreeze, closed during the day. In the bath, but also pay attention to unplug the plug, cut off the power supply, to prevent heat balance out of control accident.
Q:Solar water heater, winter can be used in rural cottage
This is the need to have a special structure of the house or what prerequisites? What brand of good point? Please experienced people under the guidance of Kazakhstan, urgent, thank you for the first
Q:Solar water heater can be used in winter
And this is a concern for many people, if not the use of solar energy in winter that means the utilization rate of solar energy is only half, this will greatly increase the cost of installation of solar water heaters, forcing consumers to choose other water heater system. In fact, the solar water heater technology now, the use of solar energy in winter is not a problem, as long as the snowstorm raging will not stop working, solar energy, free life hot water for our time.
Q:Installation of 150 liters of solar water heaters, the total down about how much money.
The actual capacity of 150L then you need to just 20 so the price if you need cheaper choose Zhejiang over the brand is probably around 1500 virtual capacity 150L then is 16 but also is about 1000 if you choose the brand if the price of 20 to 2000 more than the 16 tube tube to 1500 above
Q:Air water heater advantages and disadvantages?
Shortcomings:1 large size: air source water heater can generally be divided into integral and split two, because the city family bathroom is generally small, so no matter what kind of type, its huge body or let consumers. And requires the installation on the ground or roof, the home environment requirements are relatively high.2 frost: obvious regional characteristics, because of its environmental temperature dependence is too large, easily affected by the surrounding air environment, where the weather was cold, when the ambient temperature is low, the production of hot water quantity will decrease slightly. Therefore, the problem is also a big problem to solve frosting.3: easy to burn out compressor currently on the market of air circulation heating system is widely used in water heater, running at high temperature and high pressure conditions, easy to make the compressor aging, carbonation, if the lubrication system is not good, it is easy to cause the compressor to be burned.
Q:Solar water heater has been to overflow water
You ask them how to install hot water pipes should not be linked together(1) because the water pressure of the tap water is too large, the water will splash in the water supply process, so that the water in the water tank is not full, and it will flow out of the vent hole. Solution: adjust the tap water to the standard pressure.
Q:Solar water heater what tube?
PPR pipeline expansion coefficient is large, about 0.15mm/m degrees, which means the external temperature (such as summer and winter) or internal temperature (hot and cold) changes, a large deformation, because the PPR pipe is a rigid pipe, itself can not digest the deformation, so it is easy to cause deformation even Water Leakage pipeline system and plastic bending because of the aluminum composite pipe into a whole, the linear expansion coefficient with aluminum is about 0.025mm/m / C, PPR tube 1/6, the change of temperature, the deformation is smaller, and the plastic pipe is a flexible coil pipe itself can absorb a certain amount of deformation, will not cause the thermal expansion deformation of pipeline system.
Q:How to choose solar water heater?
In the thermal performance index, the higher the average daily efficiency is, the better the average heat loss coefficient is.2 home solar water heater is the key component of all glass evacuated solar collector tube (referred to as vacuum tube), the quality of vacuum tube directly affects the performance of the entire household solar water heater. Purchase should be carefully observed in the vacuum tube glass coating on the tube, the coating layer is called solar selective absorbing coating, because the factory production process, color coating will be different, but generally are black, dark blue or dark gray, good quality coating color uniformity film, no scratches, no peeling or shedding the phenomenon, no glass or stone section of tumor, supports the glass pipe in the correct place, not loose.
