You may have many questions about MEIRUN,we've answered them below.

Q: How does a solar water heat system work?
A: Every solar water heat system features a solar collector that faces the sun to absorb the sun's heat energy. This collector can either heat water directly or heat a "working fluid" that's then used to heat the water. In active solar water heat systems, a pumping mechanism moves heated water through the building. In passive solar water heat systems, the water moves by natural convection. In almost all cases, solar water heat systems work in tandem with conventional gas or electric water heat systems; the conventional systems operate as needed to ensure a reliable supply of heated water.

There are many types of solar water heaters. Each has strengths to recommend it for specific climates and water conditions. Solar system professionals can help you select the most appropriate system for your area and your needs.
Q: Are there any disadvantages to using solar energy?
A: The energy in sunlight can be used for many purposes, including heating water for a building or swimming pool. And using solar energy has many environmental and life-cycle economic benefits. However, solar energy heating or solar electric products often have higher "first costs" than other, similar products do. This means it will probably cost more initially to purchase and install a solar system than it will to purchase and install another kind of heating or electric system. Still, in nearly all cases, you will recover your initial costs through substantial fuel savings (as shown in lower utility bills) over the life of the product. Many solar systems last from 15 to 30 years.

Q:“how to deal the solar water heater long time no use”
A: The flat plate solar collector have high efficiency.When in the summer good day, the water will reach boiling point less than two days.If you not use water long tome,
The tank will be in the high temperature high pressure state, that will make the seal ring and MR-thermal aging, sometimes it make the tank expanded and broken, even reduce the life of tank.
Therefor,If you travel or not at home long time,you need arrange your neighbour to put hot water or shade flat plate solar collector.If you want to remove it please contact with our agents,or contact 800-828-6718

Q:Is solar water heating a viable alternative to gas or electric heating?
A:Solar should not be seen as an alternative to these heat sources, but rather a supplement. Solar cannot
totally replace the need for these sources, as there are times where there is very little, if any sunlight.
However, over the course of a year, a correctly sized solar system can provide 60-70% of your household
hot water needs. Providing more than this is unadvisable, as too much heat will be generated in the
summer.

Q: “How long will it take to recoup my investment?”
A:Meirun Solar Water Heaters are much more affordable than most other Solar Water Heaters available
on the market today. For a household of 4, may not be much more than the cost of a new gas or electric
heating system. Depending on your location (solar levels) and current hot water use, the annual gas or
electric savings will vary. However, in a normal household that spends 25% of its annual electric bill on
water heating, the full cost of the purchase may be recouped as quickly as 4-5 years. There is little doubt
that you will save thousands of dollars, or more, over the lifetime of your Meirun Solar Water Heater.
Q:Can I use a Meirun Solar Water Heater with my current system?
A:Normally, yes. Simple retrofit valves can often be used to allow solar to connect to your existing cold
water inlet. If your tank cannot accept the solar input directly, an additional storage tank can be installed
to pre-heat the cold water prior to entering the existing tank.
Q:Can Meirun flat plate solar collectors be used in cold conditions?
A:Yes. Meirun solar collectors can be used in temperatures as low as -40oC, although performance is greatly reduced in such extreme conditions. Good heat output is still achieved in mild sub-zero conditions.
Q: What is the life of the solar collector systems?
A:Meirun solar systems have a life expectancy of greater than 20 years with a manufacturer's warranty of 10 years.
Q: Can I install the system myself?
A: To qualify for an Energy Trust of Oregon incentive, your system must be installed by an eligible contractor.
