Thanks Mark, Have them fixing the old one for the 3rd time but will not give us a replacement, They dont believe there is a fault with it, they keep coming up with things at our end that will cause it to break down. First was additive in the fuel, then we had installed it wrong (there guy installed it), then we had blocked air flow etc. So we will end up with a water heater but they will not reinburse us for any costs. The australian chap we have been put onto is very abrupt to say the least. All up the cost was $10500 for all the gear, Hot water cylinder, heat pump, hot water heater, cook top. We are very happy with there gear , its there service when things go wrong that is very poor, No returning of phone calls etc.
thank you for your help and you have set up a great forum, Mark P
