Hello,
We have an air-to-water heat pump from Ochsner (Air Basic 211 C11B ELW8).
Especially when it gets cold, but also at other times, we have a serious noise problem. When the heat pump runs at high power, we hear a humming/buzzing throughout the entire house. Whether in the bathroom and bedroom on the opposite side of the house, the living room, or the basement — it resonates everywhere.
The outdoor unit with the condenser is installed on a concrete base on the roof of the garage attached to the house. The outdoor unit is located directly in front of a 2 x 1.50-meter (6.5 x 5 feet) window as well as in front of a child’s room with a window facing the heat pump.
We’re at a loss right now. Customer service was on-site—technically, the unit is fine. The heat pump is placed on rubber mats to avoid structure-borne noise transmission. However, I suspect this isn’t working very well. The noise is probably a mix of airborne and structure-borne sound.
Either we freeze now or can’t sleep due to the extremely loud humming.
Does anyone have any advice (elevating the unit? Acoustic cover?)? I have turned the heating curve down significantly so the heat pump doesn’t have to work as much, which has improved the situation slightly.
We bought the house, not built it. So far, installers have only suggested relocating the unit, but that would cost up to €10,000.
I hope someone has experience with this.
Thanks a lot for your help.
