Two-Minute Monthly Solar Thermal System Maintenance
All types of solar thermal system need maintenance, though a well-planned installation using high-quality equipment needs very little compared to most active mechanical systems.

Solar collectors are big, heavy pieces of equipment which are both very tough and very fragile at the same time. They weigh 85-140 pounds per collector (38-64 kilos) and are usually shipped on a pallet carried by a big rig truck.
So how are you going to get them safely onto the roof of your house? Carefully, that's how!
Solar thermal systems for pool heating are so common and mainstream that most manufacturers provide very detailed installation instructions. It is important to follow these instructions as they outline the most efficient way to install the equipment.
Although you may be (or think you are) an accomplished DIY expert, don't ignore the documentation – it often includes many useful hints and tips gathered from years of installation experience!
Controller maintenance is the same for many types of AC-based solar thermal system. Some of the tests require a multimeter.
Almost all controllers have two lights on the front: one that indicates the power is on and the other indicating that the pump is on. If the system isn't working, check the lights and follow these steps:
Almost all residential solar installations mount the collector on the roof or a ground frame. Once you've done your research and figured out where the best location for your solar collectors is, you'll need to work out the optimum tilt angle – the angle the collector array surface makes with the horizon.
When you opt for radiant floor heating, you opt for the most efficient, cheapest and most comfortable heating available, especially when you combine it with a solar thermal installation. The big question for radiant floor installation is how to lay out the piping that carries the hot solar fluid through the high-mass heating medium.
If you live in a location where your ICS system runs all year – in other words, where there are no freezes – you don't need to do any special maintenance. The standard two-minute monthly system check will suffice.
Before you get down to the nitty-gritty of actually mounting your solar collectors, take a few minutes to understand some basic essentials. Collectors are expensive, so you need to consider the basics of mounting them safely.
Back when modern radiant floor systems were first installed, copper or steel pipes were used. They were embedded in concrete under the floor and hot water ran through them to heat the building. It doesn't take a genius to see where the problems came from:
On top of the standard two-minute monthly maintenance checks, drainback systems need extra care. There are four main problems that could occur in a drainback system:
