StorMaxx Series
Parts are highlighted in each product sections on every product section. Buying a tank is a piece of whole installation, there a some products like piping system, connection between them and collectors. The size of this elements should be chosen in a right way suitable to installation and customer requirements.
If you have more direct questions, don't hesitate to contact us. The engineering team definitely helps you.
The StorMaxx Series include four types of solar tanks, which area designed for all working area form small to huge installations.

SE Series
Small solar tank designed for residential systems suitable max. for 3 collectors. Every tank include additional electric heater (4500 W), which can be used to heating a water if its needed. These tank have long life, so the will be higher return in investments.
CTEC Series
Solar tank suitable for combined systems (6 ports for supply , stratification and re-circulation). The tank has an easy installation process and removable insulation in order to fit in a 32 inch entry ways. In this tank it is possible to apply up to 3 heat exchangers. Suitable for large residential installation or small commercial installation.
ETEC Series
Solar tank are suitable for storage of hot water without contamination and has long-life time due to special material SUS 316L inner material. It also has a excellent thermal performance and there is a possibility to add an incorporated electric heater.
Non-Pressurized Series
Commercial/Industrial Solar Hot Water tanks which can be used in huge installations (volume from 50-5000 G). The heat exchanger is not included - bought separately. Tanks are made in the USA and there is a possibility to add up to 12 heat exchangers. These tanks can store large amount of solar energy at low temperatures, which reduce costs and improve the overall performance of the system.
The volume of storage tanks depends on type of tank. Every tank is different and has own advantage in specific area (domestic, commercial, industrial). In our offer you can find small tank for domestic usage to the huge tanks which can be used for industrial projects.
The volume of the tank starts form 50 gallons to 5000 gallons. Everyone will find suitable tank for own needs.
In our offer there are two series StorMaxx SE and StormMaxx ETEC, which have an possibility to provide additional heat form electric heat exchanger. These solutions are used in situation, when the water temperature is under the expectations. This system helps solar system to heat water inside the tank using the electric power.
There are some variables which determine the right size of solar tank:
- Annual Heating Costs
- Number Of Collectors Installed
- Water Consumption Daily/ Weekly/ Monthly
- Required Water Temperature
- Space Availability
There a some factors which can help you to determine the right size. If you need more infomation you can contact the enginnering team, they help to you to choose right tank or ask some additional questions.
There number of collectors mainly depends of the size (volume) and required water temperature. For small installations (50 G - 120G) are usually installed 2-3 collectors. The volume of the tank is a main factor in solar collector connections. Information about that are included on each product site of tank or if it not available please contact to the engineering team.
The dimensions depends on a type/model of the tank. Before you start, check on the website the dimensions of tank which you choose. Every parameter is included (diameter, height ) in the tank features and also in the specification. These dimension can help you to check/measure the space availability for your new tank.
The weight of tank depends on a size/volume of product. These information are included in datasheets and on every product size. Remember that weight is without water inside the tank, so you will have to add some extra weight.
Tank should stand on a flat concrete surface and can be connected to the ground using seismic anchor kit. The concrete pad should be 6" thick made with concrete minimum strength of 3000 PSI. Also you can installed tank on another surface, but it should resist weight of a whole system and has a optimal strength like a concrete.

What are the problems with evacuated tube solar collectors?
Evacuated Tube Solar Collectors FAQs1. What are Evacuated Tube Solar Collectors? A. Evacuated tube solar collectors are a type of solar thermal energy technology that consists of tubes made of glass that are sealed with a vacuum. The vacuum helps to reduce heat loss, making them more efficient than conventional solar collectors.2. How do Evacuated Tube Solar Collectors Work? A. Evacuated tube solar collectors absorb solar energy from the sun, and the tubes act as heat absorbers and insulators to store the heat. The heat is then transferred to a thermal storage system, such as a hot water tank, which can be used for a variety of applications.3. What are the Benefits of Evacuated Tube Solar Collectors? A. Evacuated tube solar collectors have numerous advantages, such as: - High efficiency, since they reduce heat loss due to their vacuum-sealed design; - Low maintenance requirements; - Can be used in a variety of applications; - Can be combined with other solar energy systems to increase efficiency.4. What are the Problems with Evacuated Tube Solar Collectors? A. Evacuated tube solar collectors may not be suitable for all climates, as they can be affected by extreme temperatures. Additionally, the tubes are fragile and may require an additional protective layer for outdoor installations, and the cost of installation can be quite high. Evacuated tube solar collectors have some drawbacks, including:- Higher initial cost: These collectors are typically more expensive upfront compared to flat-plate collectors, due to their complex design and manufacturing process.
- Fragility: The glass tubes can be fragile, requiring careful handling during installation and maintenance to prevent breakage.
- Replacement cost: If a tube breaks or loses efficiency, it needs to be replaced, which can be more expensive than replacing a component of a flat-plate collector.
- Aesthetics: Some people may find the appearance of evacuated tube collectors less visually appealing than flat-plate collectors, as they have a more industrial look.
- Space requirement: Evacuated tube collectors may need more roof space compared to flat-plate collectors for the same energy output, due to their cylindrical shape.
- Installation and maintenance: They may require specialized skills for installation and maintenance, which could result in higher service costs.
What Are The Volume Of The Tanks ?
The volume of storage tanks depends on type of tank. Every tank is different and has own advantage in specific area (domestic, commercial, industrial). In our offer you can find small tank for domestic usage to the huge tanks which can be used for industrial projects.Standard store tank volume depending of the number of people:- for 2-4 people - 80 Gallons
- for 3-6 people - 120 Gallons
