Which heat pump? Ventilation system / Air-to-water heat pump

Trench collectors work almost everywhere - depending on the soil conditions, you may need a bit more pipe length, but it can be calculated well.

And installing a Pana yourself is something different - with the trench collector, the transfer point is the end of the brine pipe (possibly still routed into the heating room). From there, the heating engineer continues. Effort for this about half a day to one day. If desired, you can also hand everything over to a GlaBau company, which is still significantly cheaper than drilling. And it lasts just as long as a deep borehole (identical pipe).

Well, I guess we were an exception - but since the trend is still towards even smaller plots, we will hardly remain so...

For small plots, so-called system collectors can be installed. These are then placed vertically in the ground. Under normal circumstances, however, with proper planning (installation before the start of construction), a trench collector can be accommodated on almost every plot.

With small plots, you can install so-called system collectors. These then stand vertically in the ground. Normally, with proper planning (installation before construction begins), you should be able to accommodate a trench collector on almost any plot.

Here, some people built a bungalow on a small plot and the trench collector raises the terrace by a few centimeters in winter because it is somewhat too small... It also depends on whether/what else you want to do with the plot, e.g. planting, etc. And it has to be approved. So you can't just say it always works. on the go

Don't talk so smart - it just doesn't work on every property. And that's not rare - and definitely not something done on the side. It's often said quickly that anyone can do it - but that's a misconception.

It would have been a considerable effort for us, if it were possible.

And yes, I informed myself in the pink forum & also used the trench tool and had it used.

It was not possible given the house size, the property (520 sqm, sandy soil, no high groundwater) and the heating load (8.1 kW).

Are there any independent and neutral comparisons on this topic anywhere? Preferably supported by study data? I find the topic very interesting
