Not much to do with GSHP Welda. Looks a similar thing to wave generated energy for electricity production

dnichcole

this is interesting and I will forward it to students. It seems that you are sacrificing freshwater to do this, so its applicable in a location with a good supply of freshwater - although near a sea location most rivers are estuaries and are seawater anyway. If you can pipe through some freshwater, it might work, but what power is generated in a turbine from the rate at which water can ooze through a membrane?

I know Geo, Cardews links re; 2000 metre bore hole reminded me an article I read about "osmosis" looks like hydro in another format, yes generates electricity, which in turn can be used as heat, sorry if I have ruined the thread, if you want I'll delete?

No problem I don't mind if you leave it here

I am amazed to see that 99% of Norways electrical power is from Hydro. Never realised it was such a high proportion! that also makes sense of their greater dependence on ground source heat pumps.

Welda, Please dont delete the picture! I and perhaps others have learnt something valuable and new today, thanks to you!

No problem and, your welcome.

I'm slowly getting my head around this GSHP malarky, now have a teast rig at work.

Cant say I'm impressed to date with ASHP, same technology that has been a round for yonks, have them in Florida, air/con during summer, with the flick of a switch for heat on those Christmas/New Year trips over there. Except, heat is ducted instead of rads.

How's the GSHP test rig going?
With your ASHP system you describe, then you can get the same cooling effect with a GSHP using fan coils to blow cooler air into the room from the ground loop. Alternatively, cool a underfloor heating system in the summer. A fully reversible GSHP is not really suitable for a few reasons. 1) You can not have DHW heating because it is working as a fridge. 2) Dehumidifiers would need to be installed to reduce condensation. With passive cooling this is not normally the case, although some dehumidification may be required in the first day or so, but DHW would still be effective.

Hello, Can I join in your discussion please? To set the scene.....We had our IVT C6 commissioned last week. We have a 95m bore hole. The house is empty at present so we have set the thermostat to 10oC indoor and it is using about 10kw per day. Although the building is extremely well insulated we still have the old barn door on the front so have huge gaps top and bottom and so are not running efficiently yet.

The property will be run as a self catering holiday cottage but I am not sure how well we will be able to manage the hot water for the cottage. It has 3 showers and a bath. We are going to set the system up and then lock the door to the GSHP cupboard so the occupants can't change the settings. Do you think providing constant hot water will be a problem for the cottage? We will be next door so can change settings quite quickly but I would like it to be self managing as much as possible.

Can you give me a little more info on the setup. Radiators or underloor heating. Current settings for the DHW temp?
Also, the room sensor influence from menu 2
