Alpha Plus or Omega Max 8: which Racold 100 LPD should you buy?
Alpha Plus (ETC): glass vacuum tubes. Racold notes that ETC models work better in colder regions with lower sunlight, which makes the Alpha Plus our usual choice for Ooty. Capacities: 100, 150, 200, 250 and 300 LPD.
Omega Max 8 (FPC): flat plate collectors with a Duronox stainless steel tank, a 4-in-1 multifunction safety valve and a pressure rating of up to 8 bar, so it suits homes with pressure pumps. Capacities: 100, 200, 250, 300 and 500 LPD. Warranty: 5 years on the inner container; collector 5 years (copper) or 7 years (aluminium).
For homes in Coimbatore
For a small family in Coimbatore, a correctly placed 100 LPD system covers daily bathing water on most days of the year. Many Coimbatore homes use borewell water, so the hard-water-treated stainless steel tank and magnesium anode matter here. We recommend flushing the tank once a year. Our installation team works across Coimbatore city and suburbs from our Kariyampalayam office.
For homes in Ooty and the Nilgiris
Ooty mornings are cold and the monsoon brings long misty spells. Racold says its solar heaters still use diffused light on cloudy days, but hot-water output drops in long overcast periods, so for Ooty we connect the electrical backup and set the collector angle and position during the site visit. For a two- or three-person home or a small cottage in Ooty, 100 LPD with the electrical backup connected is the practical starting size. If you need full hot water every morning whatever the weather, compare this with the Racold heat pump water heater, which Racold rates to work from −7°C to 43°C.
Which size do you need?
100 LPD: 2–3 people
150 LPD: 3–4 people
200 LPD: 4–6 people
250 LPD: 5–7 people
300 LPD: 6–10 people, or homestays and small lodges
