Gone are the days when you had to switch on our geyser and wait 20 minutes to heat up the water. Solar water heaters have emerged and with them emerged the age of clean, viable and instant hot water. Here in this post, we will tell you why it make sense to make solar water heating systems your first clean, sustainable energy investment.
Solar water heating systems are a superior option for your terrace space:
Your terrace does not care much for solar thermal. It cares about how well the space is being used.
Solar water heating technology works at 80 to 90 percent efficiency whereas Solar Photovoltaic technology works at 15 to twenty percent efficiency.
What this entails that a solar water heating unit produces the same volume of power in a 1m2 area which a solar power pack system takes 4-5m2 to produce.
You must be wondering if this a valid comparison as solar thermal systems are employed to heat water while solar power units are employed to produce electrical energy. Fair point. But in regards of power conversion all that matters is what goes in & how much comes out – the general utility of the system.
In solar powered water heating systems, 100 units of solar power go in & nearly 80 to 90 units are converted into helpful energy. The comparable number for solar power system is just fifteen to twenty units.
Solar water heating systems use a renewable & green energy source:
This may look obvious, but here are the true facts.
A household of 4 (2 adults, 2 kids), using an electric-powered geyser which runs on a non-renewable electricity source, product nearly 3 kilograms of CO2 daily. That may just be about 1095 kilograms of CO2 in a year but it produce nearly 43 metric tonnes of CO2 during a 40 year time span.
Solar water heating systems, in comparison, work on a green energy source and have a negligible carbon footprint.
Solar water heating systems have almost zero operating costs:
Solar water heater systems are zero in terms of maintenance because of the non-existence of any moving, electrical or electronic components. Intermittent upkeep is advised for regions with hard water conditions.
The sporadic use of electric backup heaters during monsoon does upshot in slight increase in operating costs. Nonetheless, these expenses are minimal & for days with heavy downpour only. Solar water heating units are unbelievably efficient even in dim sunlight. https://www.123zeroenergy.com/solar-hot-water-heaters.html
