Welcome! Here are the website rules, as well as some tips for using this forum.
We currently have a pair of high volgage thermostats controlling our oil burner (40 year old house in Northeast). We'd like to put in thermostats that are controlled by phone, but found that our wiring won't support low voltage thermostats.
Now for my $64K question. Since thermostats can be controlled remotely via phones. Why not have a thermostat trigger a switch at the boiler to go on/off via the same technology? Does such a system exist? It would enable me to avoid an expensive rewiring job.
Thanks for any suggestions / ideas.
