In the non-pressurized thermo-siphon system, its storage tank and evacuated tubes are installed as one unit on building roof. Run by natural circulation, the system can work without electricity. The Hot water flow rate of this kind of system mainly depends on height difference between the water tank and the hot water shower head. Filled with cold water in the morning, the water gets heated during the day. This hot water is stored in a specially insulated tank (PUF insulation) for use at night or whenever needed.

The pressurized thermo syphon system is a specialized dual tank system – the inner enamel SPCC tank which stores water for customers’ daily use and stainless steel SUS304 tank which stores the cycle water to transfer the heat is designed by a team of German engineers. The total system includes three tanks: Heating tank, storage tank and a small filling tank.
The heating tank is a non pressurized tank which heats the water inside the storage tank by a heat transfer fluid.
The storage tank, which is inside the heating tank, is a pressurized tank which can provide hot water for daily use.
The small filling tank is used to fill the heat transfer fluid in the gap between the heating tank and storage tank.

Benefits and Advantages

Can be easily mounted on ground and roofs.
Suitable for even high pressure installations.
Two loop circulation ensures high quality clean water.
The supporting bracket of Greenfinity non-pressurized solar water heater is adaptable to both flat and slope roof installation.

Why Pressurized System? When the requirement of hot water from a single system is more than 2,000 LPD – water does not flow automatically by thermo-siphon principle & requires additional force.
So for system of size greater than 2,000 LPD, we set up small pumps (usually of ½ or 1 HP) to force water through the collectors.
Such a system which incorporates pumps to force water through the collectors is called as a Forced Flow System
Applications • Hostels
• Hotels.
• Hospitals
• Residential Projects / Buildings
• Pharmacy, Textile & various other industries which require hot water in any of their processes or for cleaning.

Greenfinity brand of evacuated tube collectors (or manifolds) have been developed by a team of German professionals. Their outstanding design, professional finishing, top quality and high energy yield, as well as their excellent price to performance ratio make them stand out.

Every time your business uses a solar hot water heating system, you put money in your pocket. By harnessing the free energy of the sun to preheat water for commercial use, many Indian businesses can save money and contribute to a healthier environment and community.

A solar hot water system supplements a conventional heating system. Solar water heaters reduce the cost of running conventional commercial and industrial boilers by preheating the water that enters these systems. The boilers take care of heating needs at night and on cloudy days. Solar hot water systems may cost more initially than conventional fossil-fuel systems but, over time, they can save businesses a substantial amount of money and reduce GHG emissions.

At current energy prices, these systems can pay for themselves in less than 2 years, depending on the application. Of course, if the price of conventional fuel rises, payback time can be reduced even more.

Greenfinity also has Space Optimized Manifolds (SOM) collectors to design the system which occupies 30% -50% lesser space compare to the conventional manifolds systems.
