I have straight A/C with a boiler for hot water baseboard heat. I would like to switch to a hybrid-type system where the heat pump heats initially, but when it calls for the backup heat/heat coils to come on, I want it to power up the boiler instead.

As I understand it, with an Infinity Control, the only way the heat pump can power on the boiler as desribed is if it's paired with a Carrier boiler, but mine is not. Apparently, the only way it will work this way is if I use a Thermidistat instead of an Infinity Control.

1.) Is anyone aware of any other ways?

2.) Does that defeat the purpose of getting an Infinity System?

3.) What capabilities do I lose by using a Thermidistat instead of an Infinity Control?

You'll find more flexibility & adaptability w/ the Honeywell 9000 w/ optional OD stats etc to handle the dual heat.

Now that I've read this thread:

I'm not so sure it's a good idea.

It's making me wonder if I should even be getting a heat pump.

Thanks though.

There's a new -B version of the Infinity control which has hydronic heating support in it.
