Peter, you and your people have been wonderful to work with, the best. I can’t thank you enough for the quick response on short notice to the failure of our Navien unit . . . Somehow you were able to move around other projects to help us. Your man on the ground found that it wasn’t only the heating unit that had failed. Tim is a good listener and heard us talking about the heat fluctuation in the water when in use. He had a suspicion, went with his gut, and replaced the failed check valve on the recirculating line. The unit he replaced had failed in the open position. Tim also found that the original floor heating installers hadn’t installed a gasket on the in-floor heating run, and that the gasket was cracked on the return run. Both joints showed signs of leaking. Thank you to Ed as well . . . Lonestar, you, Tim and Ed, were the heroes with my family on night one with hot water . . . Lonestar was the absolute best choice for us, and the IBC system (Boiler/Indirect Tank) the best choice for the house.
