I'd say that's quite reasonable. There's quite a bit of work involved with these systems, especially all of the digging and laying the slinkies. However, the long term returns can outweigh the cost of installation.Just a thought, we are having 3 units 10x10mtrs being built for our new workshops.
My boss has the idea of underfloor heating the units and powering it via a ground source heat pump.
sounds lovely until the first quote we had was £50k
Best bit about the job is drinking the beer first..................There’s a book by Lindsay porter that tells you how to do it cheaper.
when we did a pig unit floor we put a layer of milk / beer bottles halfway deep in the concrete. Once the air pockets warm up it stays warm. Like big bubble wrap!
Spend 50k on insulation and you won't need heating or air con.

My old, now sold workshop, ex bakery was somehow well insulated, cavity walls, straw and cement 1st floor and roof, hardly needed any heat and was cool right up to the end of August most years, quite a few customers thought I had aircon for my mechanics, my newish home shed is built from 3m x 3m pallets with 80mm rockwool in the gap, roof is insulated with rockwool as is the grp door, 50mm of rockwool and a thin sheet of ply, went down there today, cool as a cool thing, in the winter the last couple of years just one oil filled radiator on most of the time keeps it all very cosy,
so my personal advice for the southern UK would be INSULATION and then you keep very cool in summer and need vey little heat in winter, even insulate under the slab if possible, what about solar hot water for underfloor heating, little cost, no maintenance, very low running costs,
you are welcome to come down my shed later this week when it hits 30deg outside!

the concrete or is already down as it’s using an old farm building that blew down a week or two back
they were planning to do a pour to make it level and that’s what got the boss thinking about underfloor heating
alternatively any suggestions for a heater that isn’t going to be as nickable as heating oil
Gas heating is good but we work on cars and throws too much moisture in the air
The trouble with underfloor heating is the slow response time so you need to have it on many hours before you get to work to give you some comfort. If you have a workshop where the doors are frequently opened then forget underfloor heating as it won't be able to cope with the sudden inrush of cold air in the winter. Also, unless the floor make-up has allowed space for all of the insulation then you will struggle with height. Pipework can't be run in the floor screed where you need to fix machinery (ramps etc) so limits your output.
If you are keen to use heat pumps then go for air source, not ground source and always have more than one unit as they need to go into defrost cycle every so often and this can cause momentary loss of heating.
We have a massive space next to the unit and was initially thinking of 1mtr deep by whatever we need to really
