What Is a Vacuum Tube Solar Water Heater?

Thu, 6 Oct 2022

The need to provide heat in homes is increasing and heating technologies are being created to meet this demand. 

However, not all of them are effective in providing adequate solutions. Vacuum tube solar water heaters are among the most efficient solar water heaters on the market. 

This revolutionary heating technology meets the heating needs of users. But how does this technology work? 


How Does a Vacuum Tube Solar Water Heater Work?

Solar vacuum tubes, also known as evacuated tubes, are made of Borosilicate glass that is very low in iron, lined up in multiple parallel rows, and supported in a frame. 

This glass lets in much more solar radiation than ordinary glass. The sun’s radiation is absorbed by the selective coating through which it travels to a centre heat pipe and then through an aluminium fin that wraps around the inside of the vacuum tube. 

After it gets warmed up, the heat pipe quickly heats the water in it and turns it into steam. The steam rises inside the tube until it gets to the condenser bulb, where the heat is transferred to the solar heating fluid inside the manifold.


Benefits of Vacuum Tube Solar Water Heaters

1. Reduced Energy Costs

The use of solar tubes means less dependence on fossil fuels. Less dependence on fossil fuels means low energy costs for providing steady and cheap hot water for your home. 

High energy costs are one of the challenges that many homes face, and using fossil fuels to generate hot water doesn't make the situation any better. Vacuum tube solar water heaters reduce energy costs by as much as 40% to 50%.

Vacuum tube solar heater systems generate clean and renewable energy from the radiation of the sun. Energy generated from the sun to power evacuator tubes costs nothing. It is an excellent choice for places in colder climates and with long winter periods.


2. Efficient at Higher Temperatures

Places with increasing differential temperature between ambient temperature and operating temperature need high-performing solar water heaters to generate hot water. 

Vacuum tubes are a suitable choice for such places. Whether it's for very cold or very warm regions, vacuum tubes are up to the task.

The system is built to strongly and efficiently generate heat, thereby producing hot water in areas with high differential temperatures.


3. Easy Installation

One of the things that make vacuum tubes highly sought-after is that they are easy to install. Homeowners want solar water heaters that won't take up much space in their homes and that will be easy to install. Vacuum tubes meet these requirements.

Many people do not install solar water heaters because they fear it is expensive. However, even if solar water heaters are expensive to install, the energy savings and the efficiency at which they operate in the long run make up for it.

Using the help of a professional, installing a vacuum tube solar water heater is relatively cheap.


4. Environmentally Friendly

Fossil fuels are wreaking havoc on the Earth's ozone layer. They increase global warming by the day. As a solution to reduce carbon footprints and global warming, countries are encouraging the use of alternative energy sources such as solar energy. 

Because they utilize solar energy to generate heat energy, vacuum tube solar water heaters do not release carbon and don't have an adverse effect on the environment. 

They are known to reduce carbon footprints by a large percentage compared to fossil fuel sources. This is one of the things that make them increasingly in-demand for homes and industries.


Final Takeaways  

Vacuum tube solar water heaters are useful when it comes to lowering energy costs, providing steady hot water, and generating heat energy without negatively impacting the environment.

If you're looking for an effective and reliable solar water heater, the SolarMate Apollo Water Heater is a good option. It is built for the highest heat transfer efficiency. 

To achieve optimum conductivity, the heat pipes are 100% copper. It is suitable for all climates from sub-zero to 90°C and areas that experience less sunlight.

Users can be sure that heat will not be lost through convection and conduction. This means that heat is adequately provided to heat your hot water system. 

This solar hot water system in Malaysia is an outstanding investment that a user can make for their solar water heating system.
