Hello everyone,
I would like to get your feedback on our offer for the heat pump and also your thoughts on groundwater heat pumps in general.
We are currently planning to use groundwater as the heat source and have received the following offer. It includes the complete installation of the underfloor heating, connection of the heat pump, etc. Only the drilling for the two wells would be an additional cost.
Water-water heat pump Ochsner GMWW 11 plus
Ochsner buffer tank PU800
Ochsner domestic hot water module
230 sqm (2,475 sq ft) underfloor heating including insulation
Various small components such as room thermostats, etc.
The total price is €30,100 gross.
What do you think? Is this a good offer? Is a groundwater heat pump a sensible choice?

We have a Panasonic 5kW (17,000 BTU) heat pump. A good and popular unit for a low price. Unfortunately, heating contractors rarely offer it. We bought it ourselves at our own risk and installed it next to the house in its place without any significant DIY work. Did you cover the heat pump? I am also considering an LG heat pump, but the outdoor units don’t exactly look very appealing.

boxandroof22 Nov 2019 08:27At our place, it is located behind the house. The appearance doesn’t bother us there.
I plan to cover it up when I find the time. Just as a precaution, even though our neighbors are relaxed. What you can’t see, you also don’t hear. If you have neighbors close by, I would definitely put up a privacy screen before installation.

neubau201922 Nov 2019 08:58Is your heat pump that loud? Ours is located in front of the house, and the neighbors directly opposite are about 23 meters (75 feet) away...

boxandroof22 Nov 2019 09:08No, it’s not. The neighbors are also 20m (65 feet) away. It can get noisy at full load, but that is quite rare and not a problem for us. I wouldn’t want it in front of a terrace anyway, partly because of the appearance. Still, it’s better to prevent problems early on, for example with a privacy screen.

neubau201922 Nov 2019 09:18How far is the heat pump from the house? Can you hear it inside?
I believe the LG heat pump is rated at 60 decibels and would be installed quite close to our house... Now I’m a bit concerned whether it can be heard indoors or if it might be annoying.

boxandroof22 Nov 2019 10:11No, there is never any noise heard inside the house. It is located directly beneath two windows. During defrosting, you can hear the pump running more strongly in two rooms, but that’s all we notice indoors. At full load in the deep winter with over 4kW (13,640 BTU/h), it can be louder if you stand outside right in front of it. I avoid that at night. But under normal operation up to 3kW (10,230 BTU/h), it is whisper-quiet even outside. I always run it in silent mode (max about 3kW / 10,230 BTU/h). As mentioned, it’s a Panasonic unit, so this may not apply to other manufacturers.
