Yep "engineered" you're correct, I'd forgotten the proper name for it and yes I'm running off same boiler as my water (megaflo, which is GREAT) and regular radiators BUT the mistake I made was running UF and Rads off the same loop/circuit so that the main central heating has to be on AND the thermostat has to be up at higher temp than what I want my UF to be at. In retrospect my UF should have been connected up to the boiler on it's own and therefore truly independent. In practise it's not much of an issue but if I was doing it again I would separate it. I guess I could retrofit rad thermostats on each rad and rely on these instead of the room stat.
Going back to quality of the flooring, we used KersaintCobb, which I think at that time had only just started making wooden flooring. My installer said that cheaper brands he'd seen were out by as much as 3mm from one end of the plank to the other and it made laying it a nightmare and therefore more like to fail in the future.
