Heatpumps, anyone want to comment if this is an decent deal?
Well, I've had a few people through. They all give different solutions and prices. However only one company I seem to trust. The guys just seems onto it where the other guys seemed lazy in their advice and knowledge. So, I am partial to investing in a system by a reputable company that I feel will do a top job. We have the following quote:
Units are *******
Downstairs: 11.2 KW central ducted system supplying 4 main rooms $10,300
Upstairs: 9 KW unit powering three high wall heads, one head in each bedroom upstairs. $6,820
Prices include gst and install
The above solution works for us in terms of heating configuration. We get a general heat throughout downstairs area, then upstairs once going to bed, we turn off downstairs central system then we can each heat our own bedrooms based on personal preference by adjusting each head in the rooms.
unless you live in siberia i dont understand why you would want heatpumps in bedrooms
So its not cold when you get up in the morning I fully understand hate getting out of bed when its not warm.
I think a lot of folks in NZ don't feel the cold. They'll be out in 3 degrees with shorts and t-shirt. I'm the exact opposite unfortunately. I've tried acclimatising, more clothes, more blankets etc and it doesn't help.

The H2 is the low-temp rating. This is really important - if your units are crap they'll spend (literally) half their time on snowy days blowing cool air round while they try and defrost. Don't accept "I don't know" for an answer.
By the way, does your installer realise how warm you like things? The standard calcs only heat lounges to 20 degrees (I think, might have been 21). Our installer took a lot of convincing that we wanted more like 24 degrees.
Thanks One. Our main goal is to "take the chill out". We'll probably still wear a couple layers of clothing while in the house. Otherwise I think we'll get carried away and get massive power bills. The COP of the central system is 4.48 (not sure of H2) and the split system upstairs would be 4.65. They claim to be rated to -15 but like you say these things trying to defrost themselves could be a nightmare. I've never run heating like this. We would have preferred radiator/boiler based heating and the quotes were over 35k, way out of reach, not to mention fuel costs.
Ones that can handle the cold is key. I had a bad experience with a clean heat scheme one that just could handle frosty mornings. Since then, I buy Mitzie hypercore ones. They cost a little more but after seeing tenants give up on the old heat pump and run LPG heaters....
Interesting. What is annoying is lack of information on particular units. For example the units I am looking at:

Seems expensive to me.
