In fairness to all, we don't discuss pricing on the Wall. Thanks for your cooperation.
Bought an old house in Northern NJ. It has gas steam boiler and one-pipe rads on 1st and 2nd floors and in 3rd floor attic room... and a hot water zone on 1st floor extension. There are multiple old wall/window ACs throughout the house. They are noisy in use and are draughty in winter even with covers.
I would like to replace the ACs with a ductless mini split system because of the age of the house. Probably one or two outdoor units and about 7 or 8 indoor units. Then I started researching mini split heatpumps - and thought that would be worth looking at... with the HP handling moderate temperatures and the steam kicking in when really cold. Let me know if this makes sense.
1. Any way to automate it so the steam kicks in automatically for emergency heat - and the HP shuts down when too cold outside to prevent defrost etc?
2. Any way with Zigbee or Redlink etc that the two existing zone thermostats could interact with the HP indoor units in those zones so it would be more integrated and easier to manage?
