Plus many places they still have a highest humidity and temp, you go from your room to the corridor and your glasses could fog up. Korea (and Japan) is very developed, not only on broadband (!). They have underground shopping malls with the walkways of (width of Wellington Airport terminal) that you can walk around it and use them to commute ie., walking down this main road b/c it would be too cold at ground level then you can take the elevators or the staircase up. They are interconnected to main buildings, hotels and subway stations. BUT, they are still warmer than many NZ homes and workplaces ;) The body can sustain low temperatures for a while. I have a photograph with the billboard behind me, that registered minus twenty something degrees. At a ski field but unlike NZ they have proper hotels on the mountain. I find NZ is blue and green with the odd white spot. NZ ski fields to me look synthetic b/c they take all the trees out. |

| 879447 | 2010-04-26 01:19:00 | I've also been thinking about getting a heatpump. But the total cost savings as others have pointed out (installation etc) over the life of the device appears marginal... Also an oil column heater will continue to provide heat after it is switched off. No power savings though, as it needed the same amount of energy to heat up the oil inside |

For us, a high ceiling HP prob the option to take, we don't have a open fire or a wood burner. 2 oil column don't do the job for us. But for the bedrooms not sure cos a 2kW oil column works for us and we could get it very warm if we wanted to, like late 20s or 30s :D I've been quoted $2,500 ish to heat each bedroom with a smallish high quality HP. Bedrooms also don't qualify for EECA subsidies, but you may get a discount from others like Genesis has a $200 discount for smaller kW Panasonics. If one expects the trend of power price increases, it again gets diminished. Inflation some what helps. I'm one of the few who does a spreadsheet out of my own interest and I can track it. IMO I think most things don't save money. They are diff perspectives thou. Take internet, for many people, if they only had internet at work / school, they would have so much time at home and money for other stuff. It's not the end of the world and for most people, internet is just recreational. For the HP I think people would use more b/c they could, they can heat it warmer, they could cool the room down in summer. |

Just because thereis no roof attic above it, doesn't mean that there is no inuslation . You could get insulation retrofited, and there is an airfoam company that pumps insulation into cavities . |

| 879450 | 2010-04-26 07:25:00 | The house is in the 80s. We are getting insulation for the back of the house which has access to roof space but the front of the house do not. There is no way they are adding a extra ceiling and then put the batts. The front of the house the window goes right up to the ceiling, if you pop a ceiling, people can see that from the outside. The top of the glass do not have curtains, the curtains go up normal height - 2m but the height of the lounge is over 4m high. Just the modern popular roof style, no screws. Dark blue or dark brown color whatever ... You'll have insulation, R1.5 or 1.8, but it's likely squashed in and less effective than it should. Better insulation would make a huge difference, but sending the heat that gathers at that great height back down would be effective too. BTW, I wasn't for a minute suggesting you add a false ceiling and put batts in it. Extruded foams combined with foils, for e.g. are far for efficient and thinner and could be attached to the existing slope with relatively minor encroachment and I'm sure the windows could be worked around as well, but if you/your parents don't like the idea it's a no goer. :) FYI, the type of roof in your lounge is called a skillion roof. Are the rafters exposed in your example or is their a ceiling lining? |

Umm .. well we had the EECA guys come and give us a quote for insulation which we have accepted. He looked at the roof space and the underfloor where there is "real access". We were told no insulation whatsover for those places. On the roof space there is a thin layer of aluminium or foil ... thing. No batts. |

However, I hope you don't have foil only insulation in the lounge roof space insulation and there definitely should be draped foil insulation between your floor joists if there is bare ground beneath . A scillion roof and impervious foil insulation is a worry, if they are correct . For starters, how the hell did they manage to assess that if the space is completely enclosed? Please don't tell me there are down lights in the lounge ceiling, as well . |

| 879453 | 2010-04-26 07:35:00 | Are the rafters exposed in your example or is their a ceiling lining? What's that in English :) I did a rafters google search . Umm . . it is not exposed . It is a flat ceiling in place but it is like a cathedral triangle if you know what I mean . So its much higher in the middle of the room . At the middle of the ceiling there is a support beam horizonal - front to back . We see that inside, one of our lights is installed on that . If you walk outside, that same support beam - the other end the top end, extends pretty much to the outside roofing . I haven't had a look at the roof space but I been told the access cuts off 1 or 2m before the lounge which is the staircase passage way . That has a high ceiling too . |

| 879454 | 2010-04-26 07:38:00 | Could be 70s dunno. Dunno if we have any down lights. The previous owner has few bits and blobs up in the roof space from that I assume there is no puffy insulation, I think family members said in the roof space it was pretty much just flat wood that you could walk on .... | Nomad (952) | ||
