Problem: Could a weak or failed thermostat battery destroy my home? We just had a new gas furnace installed and they installed the Honeywell Pro 3000 Non-Programmable thermostat. Everything works fine. But in our area, people leave their houses for a few months and retreat to the city, or head to Florida. And we keep an eye on the thermometers that they leave in their windows to make sure the heating systems are OK. I noticed one house went down to 30, called the owner, he was here in 2 hours drive.
He troubleshooted his new furnace, nothing wrong, the power had not gone off on our street. Somewhat perplexed, he came upstairs and took the front panel off the new thermostat, saw that it was not hard wired but had batteries. He replaced them, and the heating system came on immediately. He was totally astonished that the company who installed his new heating system, had not told him that the entire house heating system was dependent on 2 little batteries, and without them, the house could have frozen up and made a horrid mess. I looked at our new system, and same thing, I was not given a choice to have my thermostat wired properly either.
And then another house on the same street with people in FL was cold, a friend who had a key went in and replaced those 2 batteries and on came the heat. Saved it.
I am astonished that the people who install these lovely new gas systems, do not inform the home-owner that the thermostats have NOT been wired into the electrical system of the house, and if you are away and nobody sees the batteries going down, then here comes real trouble.
I spoke to a local insurance company and they said many of their recent clients have had claims due to these new thermostats, and have had to have extensive repairs to their houses due to freezeups.
Should I call the company who installed our new system and have them come back and wire ours properly?
Im rather shocked at this issue and found this website.
