rockmeupto125 Posted January 11, 2022 Share Posted January 11, 2022 Okay, not sure what to look for to do this. I'm putting a hydronic heater in the basement to warm things up down there, reduce moisture, and hopefully increase the overall heating in the house. It's basically a big heater core that will radiate heat after plumbing it in to my baseboard hot water heating system. I can order a plug in thermostat for the fan, but that doesn't make much sense to me. If there's no heat in the radiator, why run the fan? Once the furnace warms, the circulating pump will kick on, and the radiator will warm up. That's when I need the fan to come on, then shut off when the radiator cools after the circulating pumps shuts off. I guess I could wire a relay into the circulating pump to also switch the fan on and off, but I'd rather have a delay built into it so the fan runs to cool the unit down, I think that might make it last a bit longer. It is just a block of radiator and I would think there would be a lot of residual heat available. What sort of thermostat could I get that would turn the fan on when the temperature rises above a certain point, rather than below a certain point, and just has a remote sensor I could ziptie to the tubing? I'm just planning, I'd like to have this all figured out to install wihin a day. Quote Link to comment Share on other sites More sharing options...
