Thank you all for sharing useful experiences and issues for geothermal heat pumps

Hi All. I was reading those days your posts and comments on the last post of my blog. I found them very useful. I didn't know that the providers of heating services are so well organized and experienced. I believe the links provided are useful and also some others readers of this blog could benefit. Here I'm listing your links again. Meanwhile I would like to inform you that I'm preparing a new post where I will introduce my already 7 years of experience with operating a ground sourced heat pump.

Detailed installation Schema for Geothermal Heat Pump Project

After receiving few questions about installing heat pump, connecting to the heating system and to the water heater, I decided to publish detailed installation schema. Here you can see every valve, pump, pipes, heat pump, water heater and other parts needed to operate the heat pump.

On the upper left corner of the schema you can see the legend for better understanding of the schema. I hope I didn’t forget anything – I cannot guarantee :-)

Electrical part of schema is missing (wiring) because I’m still working on it. Hope I will finish and publish it soon.If somebody finds an error in the schema please add a comment to this post. I case somebody have further question … please do not hesitate to post your comment.

Connecting and Testing Vertical Collector for the Heat Pump

The first photo is showing a testing procedure for vertical collector. Each vertical collector should be tested before connected to the heat pump. It is very small possibility of leaking, but you must be 100% sure. Testing is accomplished with water and a water pump (hand driven) which can produce a pressure up to 5 bar. Pressure meter must be stable at least 1 hour – 1 hour the same pressure.

The second photo is showing pipes already connecting vertical collector and heat pump. There is a 0,75 to 1 meter deep channel where pipes are placed.

Drilling the hole, close-up

This is a close-up photo of drilling the hole for my heat pump project. Parallel to drilling we have chosen pipes for vertical geothermal collector. Special pipes were used. We have used more than 1000 meters.
