[QUOTE="scotston, post: 4562500, member: 32666"] 7degC lift in ambient temperature gives you 65% RH and 14.5% grain, so right now you only need air at 7degC to give you dry grain, albeit, slowly. In summer, at 25degC this would be 32degC air whereby you will dry much faster. Both of these are in the sweet spot of gshp with a coefficient of 3-4. No need to worry about 50degC, not important unless you want to stir. My drying floor needs around 75kwth to dry 200T wheat, with two 15kwe fans. So a terrific idea to use the rhi to 'multiply' the value of your turbine electric from 5p to around 40p (for tier1). I'm using the available grid export from my chp to run phase 1 of 3 gshp installs which will total around 76kwth of heating using the remaining 25kwe of export from my 50kwe chp. [/QUOTE]
