I have just brought a new heat pump (daikin) But was just wanting to hear from other people who have a heatpump as to how they find it.
At this stage we have been using it just for the heating option as its been cold in these wellington mornings lately hehe. Im wanting to know if anyone uses the dehumidifier option and if the find this effects there power bill by much. So perhaps thinking back to last winter... Any advice would be great  -------------

I LOVE OURS
we have a daiken one too and apparently they have the best air flow so they spread better. we have a realy big house so this was importnat. we leave ours on 'home leave 18' pretty much around the clock now that its getting colder and if we are all in the lounge or have the kids we turn it up to 22. lol. just the standard setting suit us fine, but our house isnt damp so not sure about the dehumidifyer but if you keep your house warm would it get damp? oil heaters make alot of condensation but i dont think you get it as much with a heat pump. we keep all the bedroom doors closed at night because BIL lives with us so have a little oil heater in our room but our power bill goes up maybe $20 a month at the very most and our heat pump is on 24/7 -------------

We have the daikin model too- the large floor one as oppossed to the wall mounted ones.... We love ours too! We put it in last winter and can close the kitchen and lounge doors and it heats up this area. We were told that they are not designed to heat an entire house - unfortunately we have a damp house so we will be getting HRV installed this Fri to dry things out a little and reduce heating needs.....
We never used the dehumidifying function on the heat pump but used the portable dehumidifyer in the bedroom which REALLY put the power bill up. And we had to use a small heater in our bedroom. Nothing better than getting up to a warm house and coming home to a warm house because ofthe preset function! ------------- My Beautiful Little Emily http://lilypie.com">

Our heatpump heats the bottom level of our house beautifully but we will need to organise something else for upstairs I think. We've also never used the dehumidifying fuction sorry.
My only issue with heatpumps is that it is such a dry heat, I can't wear my contact lenses in the lounge in the winter if the heatpump is on because my eyes dry out in a flash. |

We have a mitsubishi heat pump, and have used the dehumidifier option several times....usually when we've washed the carpet or something. For heating and cooling it's usually on 24/7, and our power bill hasn't gone up too much.....definitely not at the price of having heaters going. Worth the investment I say -------------

| Sorry if I'm repeating anyone I just skimmed through...one thing with your heatpump is don't turn it off! Set it at a temp and leave it on. It's the turning it on and off and up and down that makes them chew through the power. Say for winter set it at 17 or 18 and just leave it running all the time :) |

This is what everyone says but I don't know, one month last winter we had it on 24/7 and there was a HUGE increase in our power bill. ETA: I just went hunting for some stats to back myself up on this one and they are everywhere. It uses much more power to keep a room at a constant heat when you are not there than it does to heat it up when you return home (or program it to come on 30 minutes before you get home) Even Mitsubishi state on their website not to leave them running 24/7 http://www.bdt.co.nz/smarterheating/efficiency_temperature.aspx - Mitsi linky |

Oh wow thanks everyone. We have a small 3 bdrm house but we situated it on the wall in lounge so it also goes down the hall to get to rooms. Its heats whole house wonderfully, but havent yet used it in winter.
I have just found when ive woken up we have condensation on our windows. I was wondering if its a good idea to use dehumidifier during night and heater during day. After looking this morning though the windows pretty much cleared after having it on for an hour so maybe we will just stick to that -------------

| Just a wee note we have a heat pump as does my family holiday home and when mum was speaking to the guy from the power company they said the best thing to do is to turn it on the highest setting possible to get the house warm fast then turn it down. The main thing was to only have it on when nedded. Having saud that we have one a daiken and in the winter i usually have it on 24/7 not too much on power bill but i do notice the difference between summer and winter. This year i plan on using the timer function for while we are at work. It definately does depend on how warm your house is though. we also have a fire a mulitfuel burner and they are really good if you flip the function to fan they move all that lovely warmth around. So i would reccomend having a play and finding out what works bect for you. |

| Hi we are in Dunedin and I noticed a huge jump in our power bill when we used it the 1st winter we had it in, last winter we went back to gas which is probably just as much. This winter with bubs not sure which way we will go. |

They say the heat pump is cheaper but that is only if you use it in the same way you use your previous heat supply. If you turn it up really hot and keep it there for hours or keep it on all day then you will have an huge power bill. We find ours good but are conservative with it. The only problem I've had with it is a few mornings it was -5 and the heat pump just couldn't handle it and was blowing cold air out.
It was a life saver this summer on those really hot days, kept the babies from being hot and grumpy and kept me sane! |

We have one and they are fantastic! I agree that leaving it on all the time during winter at a set temp does work, otherwise you can put the timer on and then it will be nice and toasty when you wake. Couldn't be without one. And they are safer with little ones around.
Where are you building jjands? Know all about that one  ------------- http://lilypie.com">  http://lilypie.com">

Your looking at $2000 plus. Theres a few special around at the monent. And if you put one in try and get it on a external wall as the more distance to the unit the more pipes etc will cost. Lisha we're building in freezing old Taupo so heatpump and wood fire for us |

I just don't know where we would put one in our house.
Its a pretty annoying design as far as heating goes- high ceilings, open plan, no door to the hallway. I don't know what we are going to do to heat it effectively and efficiently. ------------- http://www.alterna-tickers.com">

We actually had 3 installed. 1 in my daughters room so we can control the temperature, One upstairs and 1 downstairs, so you can guess our bill went up. Also I guess it goes along that we are home all day now and I was at work during most of the day before. We would not have coped with the hot, muggy summer days with out it. Just remember when you are buying a pump you are not just buying a pump, you have to purchase the outdoor unit and pay for installation. ------------- http://lilypie.com">

We had a few Daikin models priced up all ranging from about $3200-$4000 for a wall model. In the end we got a perky done thru a friend so just paid for the box $2090. We were very happy people with that deal -------------
