two water heaters?
I recently spoke with someone who said that when they built their house, they had two water heaters installed on separate sides of the house. They really recommended that I do the same. They said that they don't have to wait for hot water and they never run out of it. Is this something that is common? Does it add much cost, or is it really just the added cost of the second water heater? I've heard about recirculating lines but don't know much about them. Would they be a better/cheaper option?
