If you realisticly think you can achieve 55degc from a hfc ashp specifically altherma without any electrical backup your in trouble.
Reality above 8deg c is about 45 hence why ufh is the preferred option as there's no need to blend the water temp down.
If it was cost that motivated you,then by the time you've oversized your rads,paid for the electric top up heating and had no heating in winter you'll reconsider how wise a choice altherma actually was when actually
Not having saved you that much in the initial payout.
I learnt how bad they were the hard way,hence why I'm throwing alot of my companies money to prove what actually is what.
