Solar Water Heater
The compact tube solar water heater is one of our most popular products! A sturdy, simple design that uses solar vacuum tubes to directly heat water, saving homes and businesses the high cost of heating water with gas or electricity. In all climates, whether it is the beach, mountains or down in the valley, our steel tanks will offer the longest lifespan of all the solar water heaters of the market.
The solar vacuum tubes are, contrary to what many people think, not filled with water but with copper pipes which transfer the sun’s heat through the tube directly into the water tank. Inside the tank, the hot water loses density and rises naturally, while the cold water tends to descend to the copper pipes at the bottom. Thus, the water movement is performed without the need for a pump and does not require any electrical or mechanical components. The vacuum effect in the tubes minimizes the heat loss to almost 0% and the insulated thermo tank ensures you will have hot water all day, even when the weather is cold!
The solar water tank with vacuum tubes can be mounted flat or angled on the roof or on another structure. For the installation we use a mounting frame specifically designed for solar water heaters, for a quick, efficient and secure job.
Excellent characteristics of our high-efficiency solar water heater:
- The water tank is made of stainless steel and can resist all weather conditions.
- Tank capacity available in various sizes, depending on your own level of hot water consumption.
- Internal tank layer of 50mm insulation to keep the water hot during colder nights.
- Vacuum tubes made of double borosilicate glass can withstand impact of hail, high chemical and thermal shocks.
- Copper absorption plates have a semiconductor coating for high energy absorption and low loss by radiation.
- Aluminum structure with stainless steel screws has high durability.
The glass vacuum tubes with an aluminum-nitrate coating (1) absorb solar energy, and transfer it to an internal copper heat pipe. These copper pipes directly heat the water in the insulated, stainless steel water tank (2). An electrical element and a temperature controller (3) allow you to monitor the temperature in the tank, set programs to ensure a certain temperature and if necessary to increase the heat during very cloudy days or when you have many guests using hot water appliances (4).
