- There is a Brand called Sunray from Hubli, according to him. refer to the link below for more details
- No separate water tank
- No problem of hot and cold water mixing up "from the above link, i quote from his website
1) MIXING PROBLEM:
Conventional solar water heaters require additional elevated overhead tank by that there is mixing problem. Suppose at 5am,6am-7am, hot water is drawn from the system, there is mixing of cold with that of hot water & the 4th bucket will be cold water only.
As there is no overhead tank for SUN RAY, whatever hot water is ready, say 60 degree, the same temperature hot water can be drawn upto the last drop.
I had seen this guy's stall in ACE exhibition in 2012, this guy had that innovative solar hat.
Then i went to Khadi exhibition recently and heard about Bio-fule Boilers (earlier called as Gujrat boilers, for 2KG dry water, you can heat up water in matter of 35 minutes) and from there i came across this Bangalore company http://www.bisineer.com/ yes it's kannada bisineer
This company has Geyser tied with solar (unlike) normal water heater inbuilt in solar)
- The system will have a solar water heater and separate Geyser (85Liters)
-Water will be pre heated in solar whole day, this water will be flown to centralised Geyser
- Geyser has automatic sensor, where time can be set (like morning 6-8am), between which if water temperature is not upto or liking it will heat up this to required level
- This Sufficiently heated water will flow to our hot water lines
- This can be of 2KW system, on any given day it will consume 1unit of power
- Geyser is sufficiently insulated so that water will stay hot for 2-3 days, and it will use only sufficient energy to rise to required temperature between these time only
My thoughts, please comment
- The Sunray solar looks promising, but not much brand value. I like the overall concept to avoid the hot and cold water mixing
- My electrician say you can put automatic heater to this solar tank itself which can heat water to certain time for some temperature to existing solar itself
