Yes, 3 x heat pumps to each of the 3 bedrooms (as you suggested in one of your previous posts) is at least $6000 if bought new. That's enough to run basic electric heaters in the bedrooms at night time for the next 10-20 years.
Heat transfer systems (at least those that are generally installed in NZ) don't work, period.

Let's mandate a central heating/cooling system and stop mucking around at the edges.
Go for gold - it's someone elses money anyway!

Heat transfer works fine with a wood burner only if the wood burner is big enough - i.e. was sized for the whole house, not just for the living/dining open space area. I guess usually that is not the case, i.e. sellers usually suggest a wood burner sized just for living/dining area cause it is smaller, cheaper, and more competitive to quotes from other sellers.
Also even with a big wood burner, heat transfer systems installed in usual way, i.e. warm air pumped through ducts and supply grills in ceiling is very inefficient because ceiling grills distribute warm air close ceiling and it stays there, never reaching floor level. Efficient heat transfer system should have supply grills in floor or lower parts of walls, not in the ceiling. I can imaging something like that installed in a 2-storey house with a wood burner on the ground floor, and ducts between floors distributing warm air from the wood burner to bedrooms through floor grills. But such a system is impossible to install after house is built (without cutting ceiling gib on the ground floor), and never installed in new houses, so I've never seen it implemented this way.Last edited by ivanp; 11-05-2016, 12:01 PM.

ivanp - I have found most wood burners have ample output (excessive) for the room they are installed in, especially in an insulated house.
I have also found that a heat transfer to bedrooms is sufficient to take the 'chill' off a room.
May not make it 20degrees but it raises it well up from 6 say.
Personally I don't think our winters are harsh enough, or long enough, to warrant having some of the central systems that they have overseas.
There may be a case for radiators but that's about it.

I doubt very much that the minimum temp thing will make it through Select Committee, they are not that daft and in any case the government has a SC majority. In fact the whole Bill relies on Peter Dunne's vote if it gets to second reading and he is more likely to go for some sort of concession from the government in exchange for voting against it.
Meantime the Housing Improvement Regulations 1947 require every living room to have either a fireplace and chimney or some other heating source approved by the local authority. If there is such. Landlords I know generally interpreting this as minimum of power point or two.
It's a long slow process from now to implementation of whatever is approved, if anything, by the time MBIE consults all and sundry, comes up with new regs and an implementation timetable.
There's an election in 2017 .....

My first winter in NZ started with just "a power point or two" as a heating source for the living room - we used two standalone electric heaters about 2kW each and my electricity bill in May was about $300, which was record high for us. Next month I have installed a wood burner and completely forgot that "a power point or two" can be used as a main heating source for a house.
