I looked at Piazzetta and liked that you could connect ducts to other rooms and it was quieter than Harman.
But ended up buying the Harman for simplicity of the install. Prefer to deal with US companies.
Harman was cheaper too. I got the XXV model.
Piazzetta all the way for any kind of house it may not be American made but it's got 5 years in advance on everything that is made in North America you can install a Piazzetta in any kind of construction as long as it dose not go over 2500sf there are so many adjustments that ''once done'' you will simply love your stove and you know that you have a tech that you can cont on !
Harman if only if you have an old house that meet the old way of building an as not been
