[QUOTE="gmgmgm, post: 7875900, member: 87102"] We have an 11kw GSHP, which pulls about 2.8kw when running. On start-up, it will pull much more, a guideline for compressor motors is often 3x? If there are problems, we use the log burner for heating the house. If we still have electric (through generator etc) we can run hot water using the immersion heater. If you don't have a specific immersion heater, check your GSHP manual carefully. Most have electric supplemental heat (like our Worcester/IVT/Bosch), and can be configured to use these exclusively. Ours for example, I can set to run as a 3, 6 or 9kw electric heater, which is much less vulnerable to damage from fluctuating voltage. It's in the installation settings. Your 4kw generator should run it happily. I've had to replace a few starting electrics (potential relays, caps and soft-starters) over the years, and being able to run as a purely electric heater for DHW when the compressor has been offline has been very handy.
