Our Samsung heat pump keeps shutting down due to low flow rate. I’ve cleaned the inline filter etc and the engineer is going to come out, but maybe not until Monday. We can do without heating, but can the hot water still be heated using just the immersion style heater on the tank? If so how? Thanks.
In case this is brought up by a future search, the issue was tracked down to a lump of foam insulation circulating within the system and getting trapped, restricting flow. Almost certainly caused before installation when the end of a pipe was dropped on insulation, taking a ‘core’ that was left in the pipe.
