Flat Plate Collector
With the escalating cost of electricity you want a healthy alternative to heating water. You need an option that not only saves you money but also runs for a long, long time without you having to worry about it. Please welcome the R K Solar Water Heater.
Special Features of a R K Solar Water Heater:
Collector Plate:
High performance, specially coated collector plate to maximize heat absorption from solar radiation.
Water temperature upto 60º-80º can be attained in bright sunshine.
Tank:
Unique SS304 / Copper Inner Tank: No corrosion, lifelong trouble free performance assured.
Thick insulation of Rockwool (75mm) / PUF to minimize heat loss overnight heat loss overnight.
Powder coated aluminium / SS body prevents rusting and corrosion. Hence lasts longer.
Rugged and sturdy construction design helps withstand adverse weather conditions.
Runs on sunlight. So saves electricity and thus money.
Safer than electric heaters.
How Flat Plate Solar Collector works?
Thermo Siphoning Effect.
Cold water flows down, as hot water, which is lighter due to difference in density, rises in the copper pipes.
Is it very expensive?
When compared to an electric heater the R K Solar Heater may sound slightly expensive. But a Solar water heater will pay back its investment in 2-3 years.
Besides with the Government’s push towards tapping solar power you can avail easy loans at nationalized banks at nominal interest rates.

What are the site requirements for installation of a R K Solar Water Heater?
Unobstructed sunlight on a flat or sloping roof
Shadow-free area
Close to bathrooms to avoid long piping & heat losses
A water tank at a minimum of 2.5m (7ft) above roof level
The solar panel should face south at 20º angle
What would happen on cloudy days?
The heating of water by the solar system will obviously be affected. If it is so cloudy that energy received from the sun is almost Zero, the output of solar collectors also will be nil. Therefore, for your convenience the R K Solar water heater come with a 2KW cartridge-heating element for hot water even on rainy/cloudy days.
Sizes Available:
R K Solar Water Heaters come in a range of sizes starting from 100 LPD to any size.
Commercial & Industrial Use : 500 LPD & above to suit actual usage.
