| 879435 | 2010-04-24 05:31:00 | Not sure now about the bedroom, maybe I am young and I can dare myself to brave this year with no heater at all :D The worst months are June and July. I do prefer Autumn over Summer and like skiing :p Daytime I am somewhere that provides free heat. Dinner, shower and jump into bed earlier. Better for the skin too. Up to almost May 2010, this year has been particularly warmer, here I am not used the heater yet this year and with a short sleeve shirt, the evenings I may have a light sweater or a polar fleece. I was told that multi units are more expensive and they don't share the load particularly well. If I got one for the study / bedroom, I may only save $100 a year, takes many years to get the investment back :stare: I only expect to turn it on 6pm - 10pm. Don't use it in the mornings nor overnight. Getting a Daikin for the lounge though. I just got a call back from Noel Leeming, no EECA subsidy with them, the price wasn't cheaper at all vs the professional installers without EECA subsidy, you could choose to get it too, everyone is eligible for it. So he said 24hr price only, 24 months interest free or discount for a cash payment :lol: People tell me what to do, nice try ... :angry I find that toaster shops are cheaper if you need a 3.5kW or smaller (incl installation) than the professional installers if you went for no subsidy like if it was your non-main room which don't qualify. They might be $300 cheaper. Not much. For larger units, practically the same. If you do get the $500 subsidy, professional installers might be a tad cheaper but then again a cash payment toaster shops may provide you a close discount too. |

| 879436 | 2010-04-25 06:18:00 | I was told the outside unit will last about 12 - 15 years on average, by the Daikin guy who installed mine . That is the most expensive part of it of course . There isn't much can go wrong with the indoor unit as it's mainly a fan in there . LL OK so re-does sums, gets out calculator, talks in a Goons voice So if a heat pumps costs you $2,000 and it lasts for say 10 years, then you will only have to save $200 a year to make it cheaper than ordinary heaters . But don't forget that you will only use it as a heater for 4 or 5 months . So you need to save say $40 or 50 a month on your power bill . So imho, its a bit marginal . |

| 879438 | 2010-04-25 06:45:00 | I was told that they not recommend multi units because some customers complained about not as efficient as the standalone units, also it can be pricey to route your pipes around . The multi model compressors and inverters cost more than the single ones . If you have a lounge going it may cut off the smaller rooms or take more away from it . The folks won't buy the extra ceiling and add insulation . They have this thing, they care about visual impact and want less hassle . Also the ceiling is like a triangle it points up in the centre plus there is a glass window that pretty much goes right up to the ceiling . They love their open windows . Dad even joked about if houses have a convertible roof and many years ago, they actually moved the kitchen to the standalone garage's workshop with a gas bottle burner for cooking . What age is the house that it doesn't have insulation? The best bang for buck is to insulate the ceiling and double glaze the roof window . Chucking money outside in the form of heat is not good . You could probably insulate it with a relatively thin composite material with the new ceiling lining adhered directly to it, say 50-80mm thick in total, including ceiling lining, should give you an R rating that will get you the subsidy . Another though, what sort of roof cladding is installed . If long run iron, is it screwed or nailed? The reason I ask, if it's screwed it's a relatively simple task in most cases to lift the sheets and install insulation into the roof cavity . If you have a subfloor, you should also insulate that . |

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 would struggle with even the Warehouse ones with that. The most basic installation cost are $800 - 900 what they call back to back wall. If you need it to be extended for whatever reason you could end up with a $1,400 installation price. The cheapest HP are $1,500 for a 2.8 kW which is the smallest. The Warehouse does a $1,200 for a 5kW I think. |

I don't care about recouping the outlay of the original cost, I am just happy that it is so much more efficient and keeps us warm . Also my power bills are so much cheaper in the Winter now . LL :) |

| 879443 | 2010-04-25 09:53:00 | I thought heatpumps weren't supposed to be installed in bedrooms? I recall reading in a manual for an old heatpump that it isn't good for you to sleep underneath it. Does anyone have a heatpump over a LCD or Plasma TV? I'm wondering if it would cause heat issues having the heater blowing directly onto the TV? |

Asia use them all the time with their 30+ degrees and near 100% humidity and sleep with it on but not at such a low temp that one use in the daytime thou, maybe a 23 degree. They are def HPs. You grab the remote and control likewise .. Or in Korea. I spent winter there. People in NZ complain about it being too cold but it's actually quite temperate for those in the north island at least incl the bottom but not incl Ruapehu. They have climate of negative degrees and zero percent humidity, the men use moisturisers b/c their skin dry up. We were for 5 days and we could tell. You wake up in the morning and you could get a bleeding nose, we were suggested to put a glass of water next to the bedside cabinet. Walking around with snow in your hair. Wearing puffy snowman jackets. |
