GSHP to dry grain

apologies, I have no idea what you mean - rural lift is 10%? I have a 20kw unit running with 1.2km of pipe for the last 5 years around 4 cop. No idea what the thermal conductivity is, just that it works. This new 26kw setup has around 3 times the pipe in slinkies only because mcs or whoever have uprated the original specs. In my opinion cop is more defined by the flow temp, so keep it low and you'll be right.
You need to have the correct energy to extract from the ground for the heat pump to run efficiently. You don't want to draw too much energy as it will struggle to re charge the ground again and worst case is permanent frost.

Hi. Wondered if any one had used a GSHP to dry grain? We do it with a biomas boiler and chp plant at the home farm through a heat exchanger on air floor but wondered if I could use GSHP plus heat exchanger on air flooron my other farm where we have a 80 kw wind turbine. I understand temperature will be a bit low at 50 Degc.
Hi @Hutcho, did you make any progress on this? Considering something similar myself

You should look at water source from bore hole open loop , this at 45 degree flow temperature will achieve around 5.5kW out of 1kW power and should be good enough for drying. We are looking to heat and cool thus speeding up the process with extracting the moisture with a second heat exchanger

Hi Folks,
Just jumping in here here to introduce you to our medium temperature (75oC), high temperature (80oC - 95oC) and steam series (130oC) range of heat pumps, we can provide both ground and water source units with temperature output anywhere in between to suit your applcation, with capacities from 30kW to 1.7MW, We also have a new range of air source units for 82oC currently only available in 320kW versions.
Our equipment is manufactured by Ocshner Energietechnik and we are UK export partners for them.
Please feel free to contact me directly at [email protected].

What COP can you achieve with an air source pump with ambient air temp of 0degC and supplying 82degC?

Hi Guys, apologies for ;late reply, we have been away installing.
With regards to COP as requested the tech parameters are as follows:

OCHSNER ILWHS 385 ER5c2
Operating Point Air 0°C > W 82°C
Heating Capacity 395kW
COP 1,9

The machines use 1234yf refrigerant, a low GWP refrigerant with higher heating and cooling capacity, so no electric heaters required to bring the temperature up to the higher point.

Hi @Hutcho

Would you be happy for me to chat this through with you?

It would be worthwhile seeing if we can help here with any funding requirement you may have. I’m currently quite new to the GSHP projects but really keen to understand the different benefits to the various farming sectors.

Different strokes for different folks, depends on geographic location. Drillers cheapest bit 125m then it’s gets more expensive. Your best move is to get ahold of a drilling company to check out their geo maps for an idea. Maybe contact dragon drilling?
