Gavin as ever a sensible analysis and your post has highlighted something I couldn't understand about the defrost cycle, but it's starting to make sense now ;-)
I found this in my inbox this afternoon.

[h=4]Dear Tony,
You may have received the attached letter from MCS regarding thermodynamic solar systems which tells you to contact your CB.
We are not in a position to give any guidance on whether you should continue installing these systems with the intention of receiving RHI payments. As for refrigerant issues raised in the letter we do not certificate safe use of refrigerants and you would need to ensure you meet all the necessary requirements of qualification and/or registration for this type of work.
We would suggest that you cease installation for clients who are hoping to receive RHI. It is likely if the product is accepted under MCS and RHI that they will deem it to be heat pump not solar thermal.
Provided that the issues regarding refrigeration competences are addressed by your business and because the product is approved by the MCS equivalence rule by Keymark, Benchmark will certificate these installations, however we cannot be held responsible or liable for any subsequent decisions and ruling made by DECC or the MCS regarding the status of this type of system in relation to the MCS and RHI and for any loses or claims arising from the installation of them.
As a Certification Body we are extremely perturbed that the MCS felt it was appropriate to direct installers to their CB for guidance on what is a DECC and MCS matter over which we have no control or influence.
Therefore, we recommend that you in fact contact the MCS for clarification.[/h]
