Drying Firewood when RHI payments stop.

Can you not install coils in bottom of large pond/small lake? I'm sure a fella I worked for was on about installing gshp coils in his pond when he re dug/ dredged it.

Fully aware of this idea, and I might yet re-consider it,

BUT! , no free lunches,

the heat going into the dwelling house MUST pull down the water temp in the pond/lake, which I dont imagine I want,

since I wish to encourage wildlife in and around the pond.

Odd, but true.

Why not use this moist warm air to drive any commercially available (and grant aided?) air source heat pump, for the double-win.

Well a heat pump still costs to run so if you are dumping the warm moist air at a high enought temperature to run underfloor heating, say 40C why not go direct, there's far more heat in the exhaust than can be recirculated to the incoming air.

The only building I have nearby that requires heat is the staff facilities which essentially is a mobile home/caravan. It was non qualifying for RHI when we set up our scheme and if I make it nice and toasty in there they won’t go outside and split logs in the cold and wet! 😂😂 

 

next nearest building that can use the heat is 100+ m away and the insulated pipe work to put it onto the Rhi boiler is not worth the cost. 

 

We park the old diesel forklift next to the air vent in the shed. -5 outside and starts on the button. 😃👍

Just to add to this thread a little more. Our RHI application amendment finally came through today after being submitted back in July 2017!
Put the meter readings in and for Jan to April when we’ve been drying nearly non stop the payment is nearly 3/5ths of our entire tier 1 payments! The kiln isn’t our main heat use at all but the low temperatures and high log demand have certainly had an impact on the last quarter!
