I'm curious if there are specific thermostats for boilers or at least some that will work better with a boiler. We bought a house last year and replaced the boiler, when the heat comes on it either heats ten degrees past where I set it or will drop ten degrees past where it should be before it comes on, I know little...err nothing really about boilers so maybe this is just how they work, oh and if it matters it's a commercial size boiler (house is 4200 sq ft + basement) and has two zones...any suggestions or input would be appreciated...thankya!
