ouraset - frequently asked questions

What is the difference between a closed and an open loop system?: In a closed loop system, a heat transfer liquid runs between the collectors and a jacket that sorrounds the hot water tank thereby transfering its heat. In an open loop system the same water that runs through the collectors is stored and circulated.
How many years of warranty do you give your customers?: Ouraset systems come with a 5 years guarantee.
How does the system avoid freezing?: Closed-loop system is a double-walled tank. The heat-transfer liquid flows through the collectors and the outer section of the tank. Heat-transfer liquid is a liquid resistant to freezing.
Do I have to place the system on the roof?: No, not necessarily. Pressurized systems can be placed anywhere close to your apartment; in the garden, on the garage, etc.
Does the system require a pump?: Not necessarily. Most domestic solar hot water systems do not use pumps. Pump is mandatory for larger projects or when back-up system is used. ( http://www.ouraset.com/ensisinfo.htm )
Does your system have an anode inside the tank?: Yes, it has.
Does your system have a back-up?: All systems have a room for the electrical element as a back-up. In this way they are a year-round solution to water heating.
Can I meet 100% of my hot water requirements by solar energy?: No. Asset systems typically meet 60% to 85% of hot water requirements depending on the climatic conditions of the region where it is installed.
Do you supply manuals for installation, common faults, maintenance etc?: Yes. System installation manuals are available on our website, too.
Do you provide training for your distributors?: Yes we do.
Do you also manufacture stainless steel tanks?: Yes we do.
