[DeTomaso] question for the brain trust

[Garth Rodericks]

Larry,

I don't know how you might seal your heater/boiler from the inside, but maybe it's time for a new water heater. I just installed one of these in December:

I purchased it from http://www.justtankless.com/ which is local to me and had one of the best prices. The owner/plumber told me he's doing a lot of installs in our area replacing radiant floor heating boilers with these as they can supply the home's drinking water and heat the structure, and they cost substantially less than the replacement cost of the original worn out boilers.

There was a 30% federal tax credit for 2009 which made it more affordable, but I don't know if the credit is still active or extended for 2010.

Cheers!
Garth
