I am trying to find out if there is any solution to apply a HVAC system in a building which it uses fan coil units.
The spaces are heated by the use of oil burner and they are cooling by the use of electricity. Also, domestic hot water is provided by the oil burner.
Is there any adiitional HVAC system which I can use for this analysis?
Could I construct such a HVAC system and how? (videos will help:)
Please help!
