I would really like to install a gas tankless water heater in a second
home at about 8600 feet. Since the house is not in continuous use, I
would like to be able to easily turn off the water heater. With
electricity of course, this is no problem. Can it be done remotely
with a gas tank heater? OR, is there a high volume gas tankless heater
that will function fairly well at my altitude? Any data on "derating"
the heater? Canada derates at 4% per 1000 feet. Any suggestions?
