There is very little maintenance the solar water heater requires:

a. Cleaning of the collector’s glass at the beginning of the sunny season and when needed if there is a deposit of pollutants (dust, leaves, grease, …)

b. Changing of the internal anode every 2-3-5 years depending on how “hard” the water is (the harder it is, the more frequent the servicing of the anode must be)

c. Checking (and filling if needed) the closed circuit fluid, better if at the beginning of the sunny season

d. Checking (and substituting when needed) the insulation of the water and fluid pipes

e. For the closed circuit fluid, use distilled water and approved glycol only. Do not use any other fluid mixture because this will shorten the product’s life span.
