Update on Energy Consumption After the New Water Heater

This last month, our electricity usage was down to 25 kWh per day. This is the lowest level since November before we started heating, but we are still heating some.

It is really hard to tell exactly how much of a change there is due to the fact that we were not living here this time last year. Next month may be a better indicator as we will be heating even less, and not yet using the air conditioning. That will give us a better comparison to last October which had very similar conditions.

However, the conclusion thus far is that it is helping, maybe as much as 5 kWh per day which would equal out to about $15 a month or $180 per year which is good news for the payback period analysis.

More news to come.
