We have rads, which isn’t the best to be honest, but we are using a higher heat set up so it should work. That’s why the lowest temperature is quite high. It means the water in the system shouldn’t get too cool which in turn causes a massive spike on start up. Well that’s the idea…
Underfloor is really the best route if starting from scratch.

Here’s what we’ve done over the last 3 years;
Insulated the lofts to 400mm wicks had a load of rolls on sale and quite a few split packaged ones for super cheaps:
Replaced our drafty windows with better double glazing. Including loosing some opening ones.
Got a dehumidifier and run it most of the time on its lowest setting.
Replaced the oil fuelled boiler with an air source pump (no gas in the village)
Set the hot water to 40 degrees (remember to use the immersion heater to bring it up to 60 once a month for 15mins to kill bugs)
Have the heating set to 19 24/7 and set a maximum temperature of 22 in the lounge no matter how much you push the up button.
It’s cost a fuck ton, but it’s making quite a bit of difference (I think) and most of the costs are off set be the increase in the house’s value against the leaky thing we started with.
We’re also got a wood stove in the living room with a massively over sized brick chimney (thermal mass) which warms up that end of the house in no time and stays warm for an age.
Next up is to clad the outside walls with insulation between the brick and the barn cladding. That should help a bit more and look so much nicer than the miss matched brick that you see at the minute.
