solor heating in MOAmerican Services heating installation service near Fairview Heights knows that solar liquid collectors are a viable option for central heating systems.  These are the same systems used in solar water heating.  Flat plate collectors are the most prevalent type available, but another version is the evacuated tube and concentrating collectors.  These are heat transfer fluid heating systems which use water, antifreeze, or other types of liquid which can absorb solar heat.

The controller operates a circulating pump to move the liquid through the collector.  As the fluid moves quickly through the system.  “Heating a smaller volume of liquid to a higher temperature increases heat loss from the collector and decreases the efficiency of the system. The liquid flows to either a storage tank or a heat exchanger for immediate use. Other system components include piping, pumps, valves, an expansion tank, a heat exchanger, a storage tank, and controls,” says Energy.gov.

In distributing heat for liquid systems, there are many options such as radiant floor, hot water baseboards, or even radiators, as well as forced air heat.  One of the best distribution methods is radiant floor heating for liquid solar systems because it works very well even at low environmental temperatures. Standard water heaters can be used as a back-up supply of heat.  Radiant slab systems finished with tile can take longer to heat than other distribution systems, but once they are heated up, they work very well to provide consistent heat.  The downside is that carpeting and rugs will lower the effectiveness.

“Hot-water baseboards and radiators require water between 160° and 180°F (71° and 82°C) to effectively heat a room. Generally, flat-plate liquid collectors heat the transfer and distribution fluids to between 90° and 120°F (32° and 49°C).”
