FAST installed a new gas hot water heater in Nov. 2011 in a very professional manner. The only problem we had was getting the right temperature setting, not too hot , not too cold. When PSE inspected our gas furnace we asked about our problem of too much varation in hot water temperature. The Inspector advised us that the temperture controllers can fail and we should call our installer. We did and were advised that although the tank was less than 30 days past the one year labor warranty, that they could replace the temp. control at no charge for labor and parts if done within the 30 day grace period. Two days later before Christmas, a new contol was installed at no charge and the hot water variation is much better, thanks to a tip from PSE and favorable service from FAST WATER HEATER COMPANY. We saved about $400 on this change.
