Water heater sizing & idle operating costs
I have a vacation condo that I am looking to install a hot water heater into. The condo has a kitchen sink, bathroom sink, and 1 shower. I am wanting to make sure that I have enough water to shower 2 people in a row. I have a 2.5 GPM shower head. What size water heater would be best?
I am also trying to figure out a rough idea of the idle costs of water heaters when they are just keeping the water warm and not being actively used. I was originally planning on going tank less, but I do not have the electrical capacity to do so. I am assuming I will need a 20-40 gallon water heater. If the idle costs are very similar, I am thinking the larger water heater is the way to go.
Any input is appreciated! Thank you!
