Crystal 8.5kW Air Source Pond Heat Pump for sale. It’s showing a fault code EE9 which generally indicates a communication failure between the main control board (motherboard) and the remote controller/display. Spoke to someone at crystal and a new mother board can be bought for £150. It works down to -15 it’s been on my koi pond for a couple of years and up until now has been perfect through winter and summer. I’ve decided to buy a new inverter air source otherwise I would have fixed it and sold it for more. Could be a bargain so open to offers.
