After installing solar in 2018 we started looking at Sense, which we started this energy journey with and found after Central HVAC water heating was the second most expensive thing we did here. We chose to migrate to LP gas using the tankless Rennnai whole house propane water heater and installed in the barn kitchen an Eemax ‘point of use’ 240VAC electric water. The combined electric savings of making this change paid for the new water heaters in just 16 months! So, I highly recommend the point of use and propane as the alternative to electric tank water heaters. To maintain a tank temperature all day for use when you shower once at night and do laundry every three days…. well, you see the point.
