We have a home with two 50 gallon electric water heaters. They are both working but very old (27 years). The house is 3 bedroom 2.5 bath 2000 sq ft. One heater is in the laundry room and the other in a closet by the bedrooms.
Im sure I could crawl under the house to check, but I was wondering if they would typically be plumbed together or are the hot water systems separate? If they are separate, it seems that the one in the laundry room is too big as it would only feed the dishwasher/kitchen sink and the laundry machine. Maybe a small tankless electric heater would be better here?
The second water heater feeds two bathrooms and is working okay but the temp is not consistent. I changed the thermostat a few years ago, but the problem has returned. AT 27 years old we are fine with replacing this unit. We figured we would look for the most efficient regular replacement. There is no room for hybrid and Im not sure if we want a tankless unit for bathroom/showers after reading the consumer reports.
We do have natural gas at the house, but we do not want to convert due to high installation cost.
Any advice on what would be an efficient upgrade to our system would be appreciated.
