Does it use a lot of power? Have you noticed a change in your electric bill after using this?

You most likely won't notice it, but those who want the detail then continue to read. Based on the manual the keep warm mode takes from 11W-20W per hour for the 4L version depending on the keep warm temperature. The 5L version takes about 14W-26W per hour depending on keep warm temperature. When the unit is boiling / reboiling it consumes 840W per hour, however it takes about 35-40 minutes to boil the water from room temperature to full boil. For example: We have the 4L version and we fill it once a day and set it at 175 degrees and allow it to go to a full boil. The approximate power usage is (12W * 24 hours + 840W * 0.58 hours) = ~780W for the entire day (i.e. less than 1KW per day or approximately 24KW for the month). For us 1KW is about 12 cents, so it cost less than $3 per month for us to operate.

what is the inside lining? stainless or plastic

All Zojirushi products are BPA-free. The inner container of the water boiler is stainless steel with nonstick coating, the inner lid is stainless steel, and both are BPA-free. Some gaskets and the outer lid that may come into contact with water are silicone or plastic, and also do not contain BPA.

This item is perfect in "almost" everyway! ... After 2 1/2 years, residue in the bottom is paint peeling off... any suggestions?

I can help. It's not actually paint peeling off. It's deposits from the water. I've had mine for years and here's what I do: I bought some foodgrade citric acid on Amazon and I put the couple of tablespoons and and turning on to boil and let it run for a while. This will make it pristine clean, remove all the deposits, and solve the problem. There you go!

Where is this product made?

Made in Japan. This looks like a new model. The QuikTemp feature is new. It now does not boil the water (212 degrees) every time you add water or unplug it by accident. If you have it set to 195, like I do, it only heats the water to that temperature. Thus not wasting power and time.. I had two of the CV-DSC40 VE models, both of which developed rusting issues up top under the lid. An very expensive disposable appliance. They too were made in Japan so... I am hoping this model does not rust out like the other two did. I have read almost every review of these things and it seems that Zojirushi CS is essentially useless. I just threw the others out after reading many people here say that calling them was almost pointless...But they really are great when they work or are rust free, if you drink a lot of tea or make those Japanese big boy Udon cup (bowl) of noodles. Just a bit pricy...
