Can I Connect Existing Installation To The New Tank?Dawid PYes you can. But we are recommending to use dedicated parts to our installations. All products can be easily connected using the SunMaxx Solar products. Moreover they we designed to different type of connections. Changing the parts and system installation may led to some problems or improper way of working the system. If it is not enough for you , call us we will help you.
What Part Are Needed To Built A Whole System?Dawid POptional parts are highlighted in each product sections on product site. 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. Number of additional parts depends on a size of installation and type of building. If you have more direct questions, don't hesitate to contact us. The engineering team definitely helps you.
What Are The Differences Between Storage Tanks?Dawid P
The StorMaxx Series include four types of solar tanks, which area designed for all working area form small to huge installations.
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.
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.
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.
Commercial/Industrial Solar Hot Water tanks which can be used in huge installations (volume 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.
What Are The Volume Of The Tanks ?Dawid PThe 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
How Should I Determine The Right Size Of Solar Tank?Dawid PThere 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
It Is Possible To Add A Electric Heater?Dawid PIn our offer there are two series StorMaxx SE and StorMaxx 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.
How Much Space Do I Need To Install The Solar Tank?Dawid PThe 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.
How Much Weight Should Surface Resist/Weight Of Solar Tank?Dawid PThe 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.
