Wenzhou seventy years old man DIY solar water heater
Recently, users tablet1219 invented their own "green bright spot" bright out – a homemade solar water heater.
Water heater principle: hot water sun sun
11 groups in the urban areas on the Doumen, septuagenarian Ting proud kind enough to us about this homemade water heater. Turn on the total water valve, water will climb to the roof along the hose. Position in the roof, entrenched in a nearly 200-meter-long rubber tube, through direct exposure to sunlight, so this self-heating water within the hose. When the water is hot sun, just entered the water again, screw the valve, a new hot water through the water will squeeze into the place with the iron frame at the top of the tank.
The water tank is two layers of foam made from 0.5 cm wide, which lies the long form is a common bucket, capacity about 180 liters. To be able to intuitively know the water level inside the tank, Laoding also specifically left in the tank outside the cut-off connected with the thin water bucket, put a small tube red ball, and the side marked scale. In this way, water depth, a look at the red ball at a glance. In the tank, Laoding also placed a pre-float, when the water reaches a certain height, it will automatically block the water.
Outflow of water from the tank via three-way hose will streaming all the way into the bathroom, all the way through to the kitchen, there is the connection all the way to the laundry with balcony.
Running four hours, resulting in hot water bath for four
Every morning at 11 o clock, Laoding will open the inlet valve to the yard, so water heaters start to run. Fine weather, it can until around 3 pm. During this period, he was only about an hour every two to adjust to the total water valve. This summer, his family s water heater had almost no opening, "the hot water tank reserve for four bathing no problem, sometimes left to the heat can play all day." However, this device can operate normally have to see God s face, "run into rainy days Mozhe now cooler weather, the effect is natural as before."
In June last year, this is version 2.0 of the water heater assembly. Version 1.0 was born in 1998, when the building materials business in Shanghai to do Laoding have been assembled in accordance with their own idea of ??a "one-time only to be successful, but less water than this function, only the heat that is with. "
Laoding said assembly spent a day or two. In addition to placing the formwork is to ask the master tank welding, the other key parts of the series are his own hands, "one not on the two, is not perfect and then modify …" Laoding said that although the device will sell poorly, indigenous methods is used, but it is a real energy-saving and environmentally friendly.
