Hi,

We've decided to celebrate our recently gained 'PR approved in principle' status by installing a couple of heat pumps. So far we've had two quotes, both of which seem on the high side. Can anyone recommend a Wellington-based company that will fit the bill without finishing-off our (already depleted) bank account?

Cheers

Hila

We have someone coming out tomorrow to give us a quote, I'll PM you the person Angelonthemove recommended to me. If your happy to post how much you've been quoted could you or PM me as I would like a comparrison to go with, also who have you had round?
Thanks

Thanks Ian. The post is from 2005 but it certainly wouldn't hurt giving it a try :)

Sorry, evidently too early in the day - it is 2006!

If you change the link from a post back to a thread and follow on, you will see that he is still being recommended in 2007 installations, so I'm guessing he is still doing the work?... I didn't read any further than that but people who used him seem very satisfied.

Sorry Ian, didn't mean to sound ungreatful. Will definitely give him a try.

We had heat pumps put in our home in April - used Eastside Refrigeration in Hamilton - they seemed to offer the best with time line - and costs - can send you the costs involved and sizes of our heat pumps if you would be interested .

[jandk]

size and quality counts fujitsu,mitsubishi and daikin are the better domestic i went daikin as the outside unit was smallest and it was a 5.6 fitted for $3000 as i did get several quotes and feel comfortable with the seller if you cant get recommendations. Never get just 1 quote!

[broadsword08]

for my 10 cents...
lots of people rave about daikin.... however, look at the energy star ratings and the COPs for them and compare like with like against a fujitsu or a mistubishi.... there is no real reason for choosing a daikin at all!!

[katandbob]

a lot of people have fitted these and are now moaning about their high electicity bills
just be aware that they are not as efficient when the outside temp is colder than the inside of the house.

which makes me laugh as thats when you want it on!

[Alex40]

For the record, does anyone have ducted heating on this forum?

That's what we have, and I would be interested to see what the costs involved would be.

Thanks..

We have found ours quite cost effective and warm :)

That's it; Whats a heat pump?

A heat pump is a warm air blower but also a air conditioning unit for the summer. We too have found ours cost effective , we have it on for 30 mins on cold mornings to tale the chill of before work and sometimes a lot at night and havent found our bills going up dramatically.

You may need to narrow down your description a bit so that someone can answer as there are various different ducted heating systems in use in NZ, including some that claim to be heating but are really just ventilation systems.

probably cause ur in the Nth Island (where its usually milder) - I say usually as NZ weather is very unpredictable:laugh


here is a selection of the info I found
I found some research on them and for our area they are not so efficient…



“Everyone loves the idea of heat pumps, because it’s as if they give us something for nothing. Conventional air-source models heat or cool using thermal energy that is naturally present in the air, and their cousins, geothermal heat pumps, tap the heat that is present in earth or water. These devices “compress” this energy to yield temperatures required to condition interior space. Air-source types are commonly used to condition homes and small commercial buildings in the southern part of the U.S. and in many parts of the world. Yet they’ve always been very expensive to use where ambient outdoor temperatures begin to approach and go below freezing. The reason for this is that as temperatures fall, heat pumps become less and less efficient. So, most use electric-resistance heating as a backup when a severe cold snap occurs. But that’s a bit like making buildings into giant toasters—resistance heating is not only terrible from an efficiency standpoint, but when hundreds of thousands of resistance heaters go online at the same time, electric utilities experience peak-loading. Their distribution systems are taxed, they must bring extra power plants online to meet demand, and they pay dearly to buy power from other utilities. Utility companies build these costs into their retail customers’ base rates.

Also this report is quite interesting http://www.caddet.org/public/uploads/pdfs/Report/ar_27.pdf

So people should do a lot of investigation into which makes are suitable for colder climates so they do not end up with a high electricity bill (and also more wear & tear on the parts due to the unit being on all the time, as one cheap china version in our rental blew a part the engineer did not expect to go due to the cold outside – the part containing the CO2)

Any way that’s my thoughts on the “Heat Pump” and I am looking at other alternative ways of heating our house. I have 2 engineers in our family who have ideas on how to create a efficient cheap heating source. So hopefully they will get their idea built and working by next winter!----and a large supply of HORSE Poop!!!!:exit

We are NI but had a heat pump fitted 2 months ago now. We run it from 10pm to 8 or 9 am in our bed room. We only have it set at 16 deg. , warm enough for us. We have found no noticeable difference in our bills. For us it's been great as our bedroom used to be the house original lounge, is large and has a high ceiling and no insulation. We couldn't find a rad that was powerful enough to heat the room. The heat pump brings the room up to temp in about 15/ 20 mins and is quite enough to not disturb my sleep.
