Yes, that's right, we have put in a heating coil which is variably heated according to temperature. Thus, in the bitterly cold winter nights, this coil warms up sufficiently to keep the partial pressure of the refrigerant at sufficiently high pressure to allow the compressor to continue working. It is a tough fix to make, but we hope to have improved reliability again.
