You talk about DD if you had done little, You wouldn't have to ask me if i have! And yea i do know the company is not telling the whole story, For one thing the price of this going to high, Secondly, just putting in the heater is not the whole tamala, you'll to put at least 120amp extra to accomadate the water heater,Then you can't use any other water appliances...ie, for example: you won't be able to use the dishwasher, wash clothes, if your taking a shower and vise-versa. It is for these reasons that the common man will think twice about purchasing this
