Default Solar water heating system value

Calculated using 13C/KW not 9c for a start

Remember this new thing call ed fuel recovery charge - well we get stuffed
with it and it is going up again this month

Our KW cost 2 years ago was one of the lowest in the US at 7c/KW

Figure it out

Granted I have a high electric bill from other things but HOT water is
defintely the highest cost

Lets say it saves £20 a year heating dhw only.


Energy Cost Savings and Return on Investment [ROI]:

. An average family of four uses 70 gallons of hot water per day -
. at a cost of $480 per year*
. The typical solar water heater will save 80% of heating costs -


It might do in Florida, not in cloudy northerly regions.

. or $384.00 per year
. A typical heater with hardware will cost:
. Do-it-yourself Kit - $1750
. Contractor installation - $2700
. The tax-free return on investment would be:
. Do-it-yourself Kit - 21.7% ROI [$384 / $1766]
. Contractor installation - 14.2% ROI [$384 / $2700]

*Based on 72°F incoming water heated to 140°F in Florida with an

electric
rate of $0.09 per kilowatt plus standby heat loss from a new water

heater.
Your savings may vary based on your usage, temperature, climate and
electric
rate.
