Called them up this morning at 8:00 - they were at our house with a hot water heater by Noon. Just wish they could've provided more info about energy efficient models. Thought we would be entitled to the gov't rebate of $100.00. Sadly, the model they brought over does not fall within the gov't list. Only other complaint - is it was expensive. Wish we would've gone with an independent plumber. Probably in the end though - with all the steps involved, it may have not saved us much more than $100.00 - but still we should've check out our options. Stahl provides top rate service - but you're gonna pay.
