Can you add solar?
Can you add solar?
My electric company Commonwealth Edison had Smart Meters on a trial install about 2 years ago now. I was selected as a participant in the trial. One feature I took advantage of is called RRTP (Residential Real Time Pricing), under this program the utility shows I saved over $1000.
Do you believe you really saved $1000? Is this over one or two years?
And how did you do that?
Do you run your water heater at different hours?
HVAC at different hours?
Dishwasher / Laundry?
Would appreciate what you had to do convenient or inconvenient to meet such a significant savings?
The water heater is one of the things I need to figure out. I know it's close to 20 years old and likely not very efficient. I have it wrapped with an insulation blanket, but that's all I've done. When it goes out (or maybe before), I need to look at doing something different. Maybe just a timer on this one to kick on an hour or so before I need it, or an on-demand unit of some type.
Modern electric Tank water heaters are VERY energy efficient - there's almost no heat lost. The flip side is they only recover at about 20 gallons per hour., whereas gas recover at 25-30 gallons per hour. I use a timer on mine to keep it from coming on during on peak hours. And even then - it runs about an hour per day (excluding laundry days). More people in the house would need it to run more.
Electric tankless units are not great, IMHO. Consider - I have a 9.5KW EEMax unit in my kitchen for the kitchen sink and dishwasher. This unit is on its own 50 AMP breaker and only does about 1 gallon per minute - satisfactory for the kitchen but hardly enough for the whole house. A unit that could provide a modest 2 gallons per minute (that will do 1 typical shower (2 GPM) at a time ) would take about 80AMPs. Think about that power requirement when considering using Electric tankless.
According to my bills the savings is over the 2 years. I did plan my dishwasher and laundry usage around what the predicted prices they post 24 hours in advance showed. Our basic rates are .06 to .10 per KWH depending on time of year and the RRTP prices during my two years has averaged .03 per KWH.
Bradford white is usually a good gas tank water heater. Actually set up a re circulation system not to long ago with mine. Has worked great, instant hot water everywhere all the time. Here in California, water savings is most important over electric and gas..
Personally I am not a fan of on demand systems after knowing several people who have had them. Plus its nice to have an extra 50 gallons of water or so inf there is ever an emergency.
