Operate radiators with a 35 °C flow temperature

Hi there.
I came across this somewhat older topic here.

I would like to switch from my gas boiler to a heat pump next year, possibly.
Our house is already a bit older (built in 1999), timber frame construction, and also has no underfloor heating.

I was told that a heat pump would be uneconomical in this case.
That makes sense to me, as it operates with a 30-35 degree flow temperature.

You recommended the Jaga heat pump radiators here.
I am interested to know if you are satisfied with them.
With the same number of radiators at 35 degrees flow, will I really get my place warm?

Best regards
Michael

Try first to lower the flow temperature by performing a hydraulic balancing and adjusting the heating curve accordingly. Last winter, at -11 degrees outside temperature, radiators, and a building from the late 60s, I managed with a flow temperature of 42 degrees.
