home electric progress

INDEX to the series

My latest electric bill shows my progress! In the last three months, I have used an average of only ONE ON-PEAK kWh per day. (click the pic to enlarge)

Since June, I have been actively limiting my electricity usage while it is premium priced, during the peak billing periods.

I truthfully have not been trying to USE LESS, but rather shifting my usage to lower rated periods.

Surprisingly, I seem to be using less energy also.

We have three rates here in Ontario: On-Peak, Mid-Peak and Off-Peak.

I have added timers to my fridge, freezer and water heater to keep these appliances OFF during the On-Peak. I also added about 2 inches of foam insulation to the exterior of a rather old refrigerator.

The cost of doing these things was less than $100. I had thought that if I saw a meaningful improvement, I would try to be off the grid, as much as possible, during Mid-Peak as well.

No food has spoiled, even during a very hot summer. I checked the temperatures inside the fridge and freezer regularly. And I always had plenty of very hot water even after six hours being OFF.

Perhaps the good news is that I was not using a lot of electricity. But even with the small numbers, you can see that over the last three months, I am shown as using only One On-Peak kWh average per day which is less than the two or three I was using in the months before. My On-Peak usage in 2014 and 2015 during May, June and July was also 2 kWh each month.

Encouraging!

2012 ford focus window regulator repair notes 2

This is a continuation of my original article and includes videos.


I had first looked at the control module. I don't think it would be possible to trouble shoot this effectively unless you were very determined. I looked for the obvious, bad solder joints, spider nests, corrosion, missing, damaged bits. Here is a good look inside. Mine was fine.


This is an explanation of the regulator together along with a folded view, the way it is inside the door as well as laid out on the bench so it is a bit easier to understand.


An examination of the failed motor. It still worked, went down with help but needed a lot of help to go up. Turns out it was rusty. Very strange considering the condition of the inside of the door. Where did the water come from?


A test of the new motor in the regulator before installation into the door.

As I said earlier, this is not a how-to, but a few notes about my experience, in case it helps you. I did not find much on the web when I had to do mine.

EnerGuide refrigerator test specifications

INDEX to the series

I am trying to find out more about these EnerGuide (Canada) and EnergyGuide (US) labels that are required on all the appliances we buy. Have you noticed that there are American ones and Canadian ones? There are yellow ones and white ones? There are some that have no rating on the label?

I noticed two labels in one freezer top refrigerator with different American and Canadian ratings. Do we test differently?

I decided to read what a manufacturer is told about the labels at Natural Resources Canada (NRCan), that branch of our government that administers the Canadian EnerGuide program.

You can get this document "EnerGuide Labelling Instructions and Labelling Scales for Appliances and Room Air Conditioners" for yourself from NRCan but you have to ask for it.

On page 12, you will find this statement (click to enlarge).

Here is my letter back to NRCan after getting the doc:

Thank you Lakhbir.

I am trying to understand the numbers on appliance labels and the tests that are done to arrive at those numbers. I am trying to relate mine to what I see from my smart meter data.

Do I understand correctly from the EnerGuide Labelling Instructions ... 2014 which you sent that if I want to see how my appliance is tested (ie - how the manufacturer arrives at the energy usage number for that appliance) that I have to buy a CSA specification CAN/CSA-C300-08 in the case of refrigerators/freezers for $155? (for example at the CSA website). Is this spec available on a loan basis?

Is there a repository of manufacturers' submitted test results that is publicly accessible, ideally via the web? Can I ask for a specific appliance's certification test submission?

Is there a newer Energuide Labelling Instructions than 2014?

I am a writer and a concerned individual who wants to explain the labels and the tests. How "real world" are the tests? I am interested in assumptions about household size, median test ambient temperatures and usage assumptions.

It seems there is an alternate American specification and we (Canada) are catching up?

I received the following reply the next day:

Hello George,
The labels that I sent you were for 2016.
Additional information can be found on http://www.nrcan.gc.ca/energy/products/reference/publications/14626.
This is the information available to manufacturers to create labels for their appliances.
We cannot provide you copies of test results as that belong to different manufacturers.
Each appliance has a specific standard and these are listed on the product pages on our website. http://www.nrcan.gc.ca/energy/regulations-codes-standards/6861
If you have any other questions, please contact me.
Regards,
Lakhbir

This seems to be the American standard and test procedure 10 CFR Part 430, Subpart B, Appendix A to Subpart B of Part 430 - Uniform Test Method for Measuring the Energy Consumption of Electric Refrigerators and Electric Refrigerator-Freezers

Minimum energy performance standards (MEPS) at Wikipedia
