Cons: Wastes a lot of water, Long time to reach faucet, Upgrading gas supply, Installation process, Vent kit "REQUIRED"
I truly regret going through all the changes that are required to change from a tank type to a tankless. I do not think that it is very "Green" due to the excess amount of water ran down the drain waiting for the water to reach temperature! Knowing up front that you can not install without Rheems vent kit would have saved me a week and a lot of frustration trying to locate the vent!!!
