Mini Split Heat settings based on room usage
I have a 3 story home in Boston, MA. Heat is provided to the 1st floor w/ a single zone high efficiency boiler.
On the second and third floor I have several smallish rooms that each have a new mitsu hyperheat mini-split. As of now, I only use my bedroom from 7pm-7am and my office from 7am-7pm. These two rooms are heated by mini’s that are on the same outdoor unit. As we enter winter, I wanted to know if its most efficient if the units are either OFF or ON – or, if I should maintain a minimum temp while a room is not in use.
I.e. is the energy used to heat up a COLD room > or < the energy to consistently heat a room at a certain temp when not in use?
