I'll quit after you do it
Our solar water heater is broken, and the worker's mood is low when he's working. He even advised me to get rid of my own solar water heater:
After selling, the worker said the solar water heater is no longer the same as it was. And then i threw up the flaw in the solar water heater, and i listened to it all the time — the introverts, that was accurate。
The sale price of . 01 is too high and too low
There may be a lot of people who don't know the price of a solar water heater, so let's just say, the solar water heater on the roof of a building in the past, a brand that was a little more than $2,000。
But this kind of solar energy is often unavailable, for example, at the top of my house, the roof of which is a fire-fighting site and which prohibits the installation of solar water heaters. So i had to choose a wall-mounted solar water heater:
The sale price is at least $3,000
Wall-mounted solar water heater interior component
"but think about it. Who are those who buy solar water heaters?"
Eighty per cent of solar users bought it to save electricity. But how long will it take to save electricity to save the difference
Prices alone discourage many people。
. 02 too low to complain
After selling, the workers pulled out his cell phone and showed me their internal billing system. The reasons for the repairs are simple, with 80 per cent of them having two words: not hot。
The lack of sufficient temperature is a major drawback for solar water heaters。
My house was selling it because it wasn't hot. After the sale, the worker said that the wall-mounted solar energy used in my home was no longer the same thing as the one on the roof:
The solar panels and water tanks of the wall-mounted solar water heater are separated and are connected by several pipes with anti-frozen fluids in them (which are actually thermal conductors, called “freezing fluids”). The water heater relies on solar panels to heat up the anti-freeze fluid and to re-utilise the water in the anti-freeze-heating tank。
It's very low efficiency
This solar water heater is tanned in only one case: there is no shield on the south side. A balcony like my own can only be tanned for three or four hours a day and bathed on electric heating。
. 03 maintenance is too expensive
"your family is on bail. Change it."
I can see that the worker is really going to resign, and i'm being urged to change the water heater. I'm actually lucky to be in time for the promotion:
A year of warranty and now another year of quality assurance。
But then two years went by, two years after i asked for them. Each time, there was a simple reorientation of the pipes, some anti-freezing fluids, and some thermostat repair, but there were some effects。
I used to fix it when i used to use roof solar energy
The workers told me that this was the case with solar water heaters, which were repaired almost several times a year。
Everything was said to be free of charge during the quality assurance period. But after the quality assurance period, it's not expensive to repair, but it involves high-altitude operating costs - although cheaper than air conditioning, it costs about $100 each。
04's too far away to be comfortable
It doesn't matter how high the price is, or how hard the maintenance is, just take a good bath. That's what i thought when i bought the solar water heater:
The water tanks of the solar water heater are generally 80l starters and 100 l go. And it's hot enough to blend into more cold water. Solar energy can provide more abundant hot water than electric water heaters
Of course, it turns out that "high temperatures" are hypothetical, but that's a lot of capacity。
But the capacity is large, but the comfort is low. And the workers after the sale said, "is this the kind of family that you have in the winter shower painful?"
The solar water heater can only be installed on the balcony, while my bath is in the bathroom. They are nearly 10 metres away in a straight line, and cold water is put close to one minute before each bath。
Winter's problems will be even more acute:
Turn the water off here, the water in the hot water pipe will get cold. Because the pipes are too long, the cooling is fast. Even if the water is shut down for one minute, the cold water must be repositioned for one minute。
- personal experience doesn't mean all solar water heaters are bad
