A pressurized solar thermal installation is one of the most robust options available. Your standard two-minute monthly maintenance checks should suffice to keep the system in perfect working order for at least 10 years, though you should add a pressure check to the monthly routine just to keep an eye on things.
After the first 10 years have passed, you will need to check for three possible problems:
So you've worked out which solar collectors you need, how many to install, their optimum tilt angles and everything else. Now you need to physically check that you have the roof space and plan for the installation.
Solar swimming pool systems are among the simplest available. Maintenance is equally simple and is carried out at the start of the warm season, before the system is used.
Actually mounting the solar collectors comes after you've completed the long process of planning and marking out their locations on the roof. Follow these guidelines to install your collectors:
Before you can use a pressurized solar thermal system, you need to "charge" it with solar fluid (usually an antifreeze mixture of glycol and water) so that it has a heat transfer medium. There are three steps to the charging process:
When you're plumbing flat-plate collectors, you need to attach the incoming colder supply part of the solar loop to one end of the array, at the bottom. The outgoing hot part of the loop must exit at the other end of the array, at the top.
There are three steps to the charging process. Make sure you read and understand all three stages before starting the charging process.
