How Do Solar Water Heaters Work with Solar Evacuated Tubes?

Are you buying solar water heaters? If yes, you will come across a wide assortment of solar collectors available. However, flat plate collector is the most popularly used in North America. This collector works well for residential hot water for most of the time in a year; but loses its performance during winter.

Solar evacuated tubes are highly advanced collectors used in solar water heaters that produce higher temperature. The main reason behind its use is its superior performance during winter. Heating water during winter will outform all solar collectors available.


If you’re looking to produce hot water at higher temperature, you should consider heating water with solar vacuum tubes. Solar vacuum tube collectors work like a coffee thermos. The heat energy gets trapped inside the vacuum tube and can’t escape easily.

A flat plate collector works like an ordinary coffee cup. The flat plate collector produces energy; which will escape quickly through the collector walls. When the surrounding temperature is colder, the heat loss will be much higher with a flat plate collector in winter. That’s why solar water heating systems with solar vacuum tubes are highly preferred in the Northern climates like Canada and Northern UDA.

Solar vacuum tubes are popular solar collectors in Europe and Asia because of their substantially less price. This means, the overall cost of solar water heaters has reduced significantly that make them a popular alternative for residential water heating purposes. Hence, they are rapidly growing in the United States and Canada.


The superior performance in winter and higher operational temperatures make solar water heating systems ideal alternative to homes, shops and commercial facilities. You should use a larger size system to produce residential hot water and provide additional heat to help the home heating system.

Solar vacuum tubes water heaters are considered as ideal way to capture the full solar energy potential. Residential hot water accounts for as much as 80% of the energy consumption at home.

When installing this system, you have to remember that heat energy demand during summer is zero. Therefore, the additional solar heat needs to be controlled. It can be done by diverting the heat energy to pool or hot tub or by using simple covers.

Northern Lights Solar Tubs specializes in providing solar water heating systems by using solar evacuated tubes ensuring optimal performance and maximum energy efficiency.

How Do Solar Vacuum Tubes Work?

A solar collector works like an engine of any solar water heating system. Solar vacuum tubes are very much efficient in producing solar powered systems. The vacuum tubes work similarly like the coffee thermos.

The vacuum tubes comprise of two glass layers with vacuum in between the layers. The outer layer of the tube is made from Borosilicate glass, which has very low iron content. The Borosilicate glass allows around 98% light energy to enter. The second layer is applied with special coating.


However, there are two types of solar vacuum tubes used in solar water heating systems like: Open Vacuum Tubes (Non Pressurized) and Heat Pipe Vacuum Tubes (Pressurized).

How Does Non Pressurized Vacuum Tubes Work?

These heat tubes use open vacuum tubes. Water fills up the inner vacuum tube and gets heated internally by the sun likewise liquid in a thermos. Generally, warm water is lighter than cold water. That’s why it rises up to the top of the tube where it fills the collector.

The heavier cold water goes to the bottom of the vacuum tube to take the place of heated water which will be heated again by the solar energy. This is a natural phenomenon, known as thermo-siphoning. The main reason behind using this heat system is that no expensive copper piping is used, making open tubes much more cost effective.


One disadvantage is that they can be used only in an open loop system and controlled by atmospheric pressure. This type of heating tube is ideal for swimming pools as water flows directly into the tubes. However, non pressurized vacuum tubes are used in applications above freezing. As a result, they can withstand small amounts of pressure and can’t be used in the most closed loop applications like residential hot water and space heating.

How Does Pressurized Vacuum Tubes Work?

Pressurized vacuum tubes are considered as high performance heat tubes that extend the possibilities of water heating through solar power. Its working principle is same like the open solar vacuum tubes. Only difference is that water doesn’t enter the vacuum tube physically.

However, the specially designed hollow copper heat pipes are inserted to the vacuum tube. Copper is an excellent thermo conductor as it conducts heat efficiently. The heat pipe contains pure water residing within vacuum.


Water will boil at less than 30 degrees. The hot vapor rises quickly to the top into the condenser tube. The condenser bulbs start transferring heat to the manifold (heat sink) in contact with it. They are specifically designed to attain temperatures of 200 degrees Celsius or more.

High temperature inside the heating tube results in higher efficiencies. The condenser bulbs are inserted into a copper heat transfer manifold by using multiple tubes. These manifolds can be able to withstand around 116 PSI pressure.

Remember that, the water present inside the heat pope system enters the vacuum tube. It means, this heating tube can be used in systems in colder climates. If a vacuum tube breaks down, the system continues functioning without any hassle.

The heat pipe solar tubes can be used for different applications like hot water tanks, radiators and in-floor heating. The copper collector carries a small amount of liquid and can be used with any heat exchanger by using glycol mixture to prevent freezing.

Bottom Line –

Are you thinking to use solar vacuum tubes? If yes, then you should definitely look no further than Northern Lights Solar Tubs. For professional help with the purchase, feel free to reach out to us at  +1 (800) 317-9054.

Using Solar Home Heating Systems at Home

Solar home heating or solar space heating systems are gaining popularity in the solar water heating industry. It’s because of the extreme high efficiency and higher operational temperature by solar vacuum tubes.


Solar evacuated tubes work in low light conditions and temperature that attain minus 35 degrees. Most Northern USA, Canadian and European homeowners are using solar home heating systems at home.

Most people integrate solar thermal kit with an existing heating system like radiator, in-floor heater, or forced air heater. You can save up to 50% of your heating bills. After all, your home heating consumes a significant amount of your energy bill and its payback can be under five years.

Solar home heating systems use the solar vacuum tube collectors to absorb solar energy. After that, the energy is transferred to a solar storage tank or a concrete pad – in floor heating. The amount of heat stored is integrated with existing heating system to the heat supply.

However, a large size 119 gallon storage tanks can hold enough energy. It can be used in the evening to supply heat as the sun is not shinning at that time. Winter experiences higher demand of heating and a secondary dissipation loop may be required to offload the heat during summer months.

If you have a hot tub or pool, the excess amount of heat energy can be transferred during summer proving you with free pool or hot tub heating and space heating in winter. A dissipation loop like buried pipe or exterior fan can be required to dump the heat. Use a geothermal system to remove excess amount of heat in the summer and store it in the ground for the winter time use.


Generally, solar home heating or space heating kits are used in colder areas – where they are susceptible freezing. A special solar glycol heating fluid helps in avoiding damage that would be caused by frozen pipes. The special fluid can even operate at minus 40 F and even temperatures as high as 480F.

123 Zero Energy offers specially designed solar storage tanks with capacity of 119 gallons every day to hold 120,000 BTU heat energy at any time. If you’re lucky enough to own a pool, you know that Northern USA and Canadian season is almost short. Use solar energy to heat your pool during summer and heat your home in the winter months.
