No they dont ,when I lived in the U.K our House, had Hot water Radiators in every room, heated by our Fire, and run to the Radiators by an electric pump.

That may be so, but if the air is warm enough, I am satisfied.

which is one of the reasons I hate the idea of buying another house and moving. We spend a lot of time making sure our house is properly warm and dry and many other people don't do this with their houses.

exactly. they are typically more interested in adding bling so they can sell for more profit.

Don't get me wrong, I always like to insulate the house to the max and ensure that we have absolute maximum energy efficiency, but we will only heat rooms we are using at the time.

to the max you say? i doubt that. very few in nz actually understand what "max insulation" or "max energy efficiency" actually is. they do build those homes here and not one of them would "only heat the rooms we use".
i do apologise, i'm not trying to make fun of anyone, its just most people have absolutely no idea and i do not expect them to. they pay the building industry to do that for them but are let down because the industry is geared for minimum code.

I mean, I try to insulate the house to the maximum practical level. For example I have about 4 layers of R3.6 insulation in the ceiling; it is about half a metre deep.

don't mean to break ya balls but 500mm of insulation is not excessive. i would have to go check but thats basically close to what it should be to start with if kiwis built decent houses. edit: double checked and i was wrong. your around double what would be good.
maximum practical. have a look overseas where they have well over 1m thick ceiling insulation. the man hole is a tunnel (and has its own insulation setup) where 6" walls is minimum code, 8-12" is not uncommon. often with external insulation as well. even here its practical to take off the cladding and fit 2" external insulation, then re clad. 6" insulation would be ok for south island.
i don't think many people here actually understand what can be done.

Yeah I agree, fires and heat pumps make you soft. Eventually when you are in a cold situation you can't handle it. I am still in singlets, t shirts. shorts and jandals when I go out and no sign of any flus or colds touch wood. Mind you it is warmer up north here.

btw keep in mind going overkill insulation one part does not make up for deficiencies in other areas. insulation doesn't work well if there is a hole for the heat to go out through. you still need comparable insulation. eg having poor windows but great wall insulation still means its pretty poor. better windows but lesser walls would actually work better.

And there I was feeling chuffed with my double layers of 4.1. Still, the old girl is ninety years old with lots of holes in her knickers, chucking on another wooly hat would be a waste of time. The 100mm poly underneath did cut a lot of the air flow through the floor though.
