Noisy geothermal heating #111

Open scripting opened 5 years ago

scripting commented 5 years ago

My new country house has geothermal heating and cooling, which is something I didn't know existed until I found this house. It's supposed to be a lot less expensive. It uses electricity to move water around to transfer heat from or to a pool of underground water that's at a constant temperature of 55 degrees. In the summer, it's used to cool, in the winter to heat. Genius.

But just before the heat comes on it makes a very loud jarring sound, like someone slamming a garage door shut. It rocks the whole house. It wakes me up when I'm sleeping. There's no preparation for it, it just happens. It's basically not acceptable. I don't want to get used to it.

I've tried searching on the net for ideas about how noisy these things are supposed to be, and no one talks about this loud sound.

I have to find someone to come out and take a look, but I don't know how to search for someone who does maintenance on geothermal heating.

I love the idea, but this is not an acceptable situation. I may have to switch to conventional heating and cooling.

PS: An AirBnB I rented the week before had the same problem. It was worse because the heat was going on and off all the time. So it was garage door slamming all night long nonstop. Needless to say I didn't stay there the full time I had reserved it.

Heat pumps might emit low frequency noise, but should not produce loud jarring sounds as described. Are you sure it is the heat pump/geothermal system, and not the system distributing the heat/cooling (i.e. ductwork and vents). If it is the distribution system, then I would call a (local) plumber that works with heating and cooling. (If you think it is the heat pump, then I would call a technician that services that brand of heat pumps). Edit: It might be your air filter: https://youtu.be/zos3ZRqiVAY

I am wondering if this is a water hammer effect in the Geothermal system. If it is you should be able to have it mitigated.

Have a hammer arrester installed and/or switch out the valve to a slow open/close type?
