Today we had the (late) Fall Fill-up.. 80.7 gallons @ $3.59 = $281.64 (after QPD). Since the last fill up on 02-02-11, It's been 288 days or 9 months, 15 days. That equals 0.28 gallons a day.?. $1 a day (at today's prices)!! This little timer has paid for itself and then some.. Seems that solar assist is helping out too. Dang, I've got to optimize that thing ASAP..

50.7 gallon oil fill..
Quote:
It's been 73 days, and we just had a visit from the Oil truck! He Pumped in 50.7 gallons. @ $3.49 quick-pay-discount, is $176.94 50.7 / 73 = 0.6945 gallons a day, which is only a tad high. That's more than our goal (0.5 gal per day), but we did have a couple of nights when we used some back-up oil-heat, and a few evenings, when we needed extra hot shower water.. Over all, we've been very happy with the operation of the Timer.. Edit: This morning, we decided to change the timer to 8:30 AM.. For reason, see http://ecorenovator.org/forum/solar-...html#post19447

It's been 95 days and today the oil truck was here again!
45.3 gallons ($3.69/gal) is 0.477 gallons per day. Pretty close to our goal of 1/2 gallon. In the fall, when I did the burner maintenance, I was really pleased to see how clean the filter and flame retention unit was. Running 1/2 hour a day has it's good points too. If I can get the heat pump project running, we might end up using much less (if any) oil.

I hacked my water heater today before I read this thread. Its electric 4500watt elements. The top one comes on first, when it meets its setpoint it lets the lower have power to make its set point. I set the top to ~110 qnd the lower to 125. My timer is an intertec, ifound, it nneded a clock motor( $18 ). I put the timer in to interupt the lower elements normal cycle. It now only comes on when my solar pv panels should be producing. It is better to use than to sell. I have thoughts of putting lower powered elemnt in lower position. solar panels can barely hand an element.
I am retired so in the day time I try to do things that can use the solar power, and avoid night uses. I welcome suggestions and thoughts on my hack job. |

Hi Ferg,
I installed a new GE hotwater heater this summer. I think it also has 4500w elements. But, I got it for my A7 Airtap ASHP project and didn't plan to use the 4.5kW power hog mode at all. I did test the tank using the 120vac.. Works nice! http://ecorenovator.org/forum/geothe...html#post23896 Only uses 1.130 kW. Making 3856 BTUh of warmed up water.. Maybe your PV can handle the load at 120vac? At least during the daylight hours..?. The negative side is very long recovery time. But, it might be okay, depending on your hotwater needs. ~~~ Anyways, we're now using a timer that keeps the A7 off, between 10:30PM & 6AM. Since we aren't going to be using any hot water during those hours, I don't think we are going to run short of hot water at any point. (During our normal waking hours). There might be some small power savings.. I really don't care, since the power use by the A7 AirTap is already pretty insignificant at 15 cents a day. This PC uses a LOT more than that per day!!

"Only uses 1.130 kW. Making 3856 BTUh of warmed up water.."
Umm 3.412 * 1.13 = 3.855.6 You've got the same efficiency as power hog mode, except with a long recovery time? ..or you've made a mistake somewhere along the line with the output or the input number. |

I don't use the 4.5kW elements, I just tested them, using 120vac. I only use the A7 ASHP to heat my hotwater. Which is super efficient. <1kWh per day . I do use some resistive electrical heating in the old oil burner.. But it's all from PV.. (DC @ 800W max).

120 volts huh, I,ll try that since the outlet was wired with neutral.
Any more suggestion to insure I make hay while the sun shines ( use solar automatically). |
