We just bought a house in auckland and have been thinking up efficient ways to heat it.
It's two storeys, and the main problem is the living area is on the upper floor, and the bedrooms down below.
The ground floor is partially underground as it is on a sloping section and the front half of the ground floor (It's a rectangle shape) is underground up to a maximum height of about 1.5 meters.
Because of this, the bedrooms, especially the master bedroom which is on the south side, get very little light and heat - so can be kind of cold and damp during winter.
The ground level is all cinder block, and the upper level appears to be well insulated - so insulation seems to be in check (short of dbl glazing). The floor between the levels is also insulated from what i can tell.
So we are very keen to put a fireplace in, as the living area is well suited for one and we both love the ambience of a fire.
I was thinking of getting a wetback, and installing a radiator in at least the master bedroom to get some of that heat downstairs.
Can I do that? Given the old heat rises thing. I'm assuming a pump of sorts can override the thermal rise.
Also our HWC is on the ground floor at the opposite end of where the fire would go - talking about 10+ meters away. Is this too far away to run piping too?
The other issue I face is air movement. Again the master bedroom has little in the way of ventilation, so trying to figure out the best way to get some air movement going through there. Could I install an HRV/roof space fan thing, and then have a pipe running directly to a lower floor vent. I realise that won't do anything heating wise, but would hopefully help with moving air.
