The glycol inside the panel is solar UV heated and by convection the hot glycol starts circulating into the tank (goes up) and water starts heating up by absorbing the glycol heat.(heat Exchanger)
When the heat from glycol is absorbed, the cold liquid will then go down again into the panel .
This system will then process itself by natural convection, where heat goes up and the cold goes down, and by this method, the SWH will function naturally and generates hot water.
The system consists of a digital temperature meter where it shows the water temperature inside the tank.
3. Can I get some information on the tank ?
The main tank consists of two sections (the inner tank and the outer tank). The inner tank that holds water is made from low carbon steel and coated with Enamel Glass Line (3mm thick) (Porcelain).
The outer tank (outside inner tank) stores the glycol (solar liquid) to heat the inner tank and hence water.
The above-mentioned tanks are insulated to prevent heat loss.
The outer tank material is stainless steel.
The system is also equipped with an “Expansion Vessel” to prevent damage to the system during high temperatures.
4. Will I have hot water during non sunny day ?
The solar heating system is equipped with a backup heating element used only when no hot water is available.
This back up heating element can be switched on manually or automatically.
5. Does this need any Servicing ?
Service needs to be done every two (2) years and this is obligatory (for warranty cover).
When we provide the date for the appointment we advise that one day (winter season ) and ( two days minimum during summer season) before service it’s Important to cover the panel to cool down the SWH (you can use Hot water normally to cool down SWH).If system is not covered and water is still hot service will be re-scheduled at a charge.
During service, SWH is drained from water and inner tank cleaned from water scaling.
Magnesium Anode stick replaced.
Glycol (Solar Liquid) is checked and topped as needed.
In summer, we suggest that the panel is covered to prevent extremely high temperatures that can lead to high scale build up.
6. Guarantee ?
The Solar Water Heater has a 5-year warranty parts and labour.
The 5 years covers the inner tanks and the solar thermal collector (panel).
