Based on options that I have, I choose option 1 is more likely for me
Option 1 : buy new heat pump Mitsubishi 7,5kw, 5kW not available.
- eazy installation
- if I want to sell the house is better
- service friendly, not need my assistance
Option 2:
- finding the right unit is not easy
- hi COP unit rented to 5 is expensive
- lot of chalanges
- warranty lost
Option 3:
- gas boiler is half price of heat pump
- gas price is more volatile than electric
- cannot be used with PV panels
- yearly authorized person verification needed
