Back in 2008 I had 2 Carrier Infinity systems installed in my house, and since that was the year of high oil prices I had them install it as a dual fuel system - about 35-40 degrees it uses a heat pump and below that uses oil hydronic heat. It's worked great since then.
But now in the Northeast we've had entirely too many week long power outages so I'm looking to install a permanent backup generator. The generator people are asking me to find out if the Infinity systems can be configured to skip the heat pump stage and go right to oil heat in the event that the system is being driven by the generator - this would greatly reduce the size of the generator required and save me a lot of money.
I'm a little afraid that since this question is off the beaten trail that it might be over my local installers head, but Carrier won't talk directly to me. I'm not trying to do this work myself, just trying to find out for sure what the correct answer is and steer my installers in the right direction.
Does anyone have any info on this?
