Trane Heat Pump Alternatives
I am about to purchase a Trane 5 ton heat pump, primarily used for heating, and have narrowed down the choice to two models:
Trane XL16i - 4TWX60E1000A, with ECM blower - TAM7A0C60H51SA & 10KW duct heater OR
Trane XL20i - 4TWZ0060A1000A, with ECM blower - TAM8A0C60V51CA & 10KW duct heater
Given the primary heating requirement is there any advantage to pay the small premium for the XL20i? Noise, reliability etc.
Also any comments - good, bad, or indifferent - on the Confort Link II thermostat (TZ0NE950AC52ZA), and the Clean Air Effects electronic filter?
Thanks in advance.
