I just did one in a condo. The guy had a 50 gal power vented water
heater. He wanted to change it so I gave him a price. He was shocked
as most are.
Anyways, I started asking a few questions. I found out he was THE ONLY
person in the condo. I asked if he ever had family or friends over to
spend the night. He said not enough to warrant a bigger heater just
for those couple times. I asked if he had any large whirlpool of hot
tub. He said no. I sold him a 50 gal electric water heater. Main panel
was about 15 ft of wire away and no holes, ceilings or walls to go
through. Many spaces left in the panel to accept a new double pole
breaker. I installed a 3" pvc cap on the old vent. Electricity is
relatively cheap here compared to gas so it was a no brainer.
