Daewoo Heat Pumps
John
just under a thousand bucks (plus installtion).
Anyone have any information in regards this unit? Has anyone got this
heat pump installed? If so what is your recommandation?

Great things - heat pumps, but only if you install the right one to match
requirements. e.g. Some sold in the south have been close to useless, but
would be fine in the north. A lot dependes on minimum temperature in your
area and whether you intend to use it mainly for heating or as an air
cooling conditioner. Get the wrong one and it will chew up large quantity of
electricity trying to do what it really wasn't designed for. So ask around
or best of all check with a refigeration outfit who sell and install them. A
lot of them produced are more designed for cooling with heating being a
secondary requirement. They are made for the Asian market, a very different
clmate, and are cheaper to import. I am not saying this applies to the
Daewoo model - but it could. Compare price with a leading brand such as
Daiken. Depends on specs, but warehouse one may not be much cheaper. But do
the research and get it right.
John
Thanks for the information Fred.
I took your suggestion and rang the local dealer for Daiken but the
price was over bouble the Daewoo (5.9kw $2603). The price is the
reason I'm interested in the Daewoo I could Purchase the Daewoo and
get it installed for less than the Daiken unit and as I'm on a fixed
income the price is all important. However, saying that I don't want
to purchase the Daewoo if the unit is crap:-)
Fred
Yes - that's the point. The cheap ones have in some instances been far from
cheap, because they are either useless or not efficient and cost heaps to
run. Get the Daiken dealer or similat to call and quote. Most should give
you a free quote - so try a couple and listen to them. I'd even say you were
thinking of the warehouse one, and wait for the comments. Ob viously they'll
push their own barrow - but get to the bottom of their reasoning. Trouble
is unlike most appliances, once installed it's a hell of a job and expense
to change them. Make sure the 5.9 kw is correct fot the use. You should
also find out whether floor or high mount is best. and also if your
preferred location is the best place to install. All very important to get
the best bang for your buck.

It gets a 3 1/2 star energy "star" rating for heating.
That's not a high rating, but note that there's only a couple of hundred
$ difference in 10 year energy cost (say based on 600 hours/year use
heating only) between a 3 1/2 star and a 5 star rating of the same
output capacity.
Note that the Daewoo model doesn't have a "Variable Output Compressor".
I think locally they call variable output compressor types "Inverter"
heat pumps. The advantage is that once target temperature is reached,
as the compressor pump motor is a variable speed DC motor, it can be
slowed down so that the pump keeps working at reduced heat output (using
less electricity). This is more efficient than AC motors which run at a
continuous speed, so inverter types tend to get higher energy star ratings.
For the difference in price you stated, you'd probably never recoup it
(*if* the Daiken is more energy efficient - which it probably is) over
the lifetime of the unit.
There are some units available with "quick-connect" hoses and valves on
the refrigerant lines - allowing owner-installation.
Installation/placement is limited by length of lines supplied. The
retail shops do not like selling them, as they lose the commission they
take on installer referrals.

inverter. I use an old (pre-inverter) model in one living/dining room, and
also a newer inverter in a lounge. I only use for heating and would not ever
go for a non-inverter nowdays. The old one is great - but the room does not
stay the constant temp. of the inverter.
Me
temperature as well as the new model - other than the fact that it's not
an inverter model.
If you're looking for one that will be left on at preset temperature
most of the time, then an inverter model is better for energy use.
As you point out, these aren't things that you can chop and change
easily without considerable cost That means thinking it out, but also
allows for the sellers to indulge in plenty of salesmanship.
I see the Mitsubishi ads on TV claiming efficiency down to -15 deg. I
live in Chch, and it never gets to even -10 deg C here (OK- someone
prove me wrong - but at best I'll revise that to "almost never").
I'm confident that the *crappiest (TM) heat pump is going to use a lot
less electricity compared to any conventional heater of the same output.
I guess $800 typical minimum install cost is a problem for many people.
I don't think that price is a "rip-off" - except if an install is
straight back to back, with a pad ready to place the outdoor unit on,
and house mains wiring already set up (close to) where it's needed. If
that was the case, then perhaps an installer might offer a better price
for a "cashie", but I expect he'd want it kept quiet, and this probably
isn't the time of year to get such a deal.
John
Went back to The Warehouse and got hold of the information sheet. It
states that the unit has:
24-hour timer that can be set to conveniently start or stop at any
time within a 24-hour period.
Temp Compensation - The ceiling temp is often higher than the floor
temp. This function can automatically eliminate the temp difference
between them for a more even temp distribution.
Sleep Mode - This function enables the unit to automatically increase
cooling or decrease heating 1 degree per hour for the first 2 hours
then hold steady for the next 5 hours after which the unit will stop
operating. It can maintain the most comfortable temp and save energy.
Independent Dehumidification - The unit will operate in cooling or fan
only mode which ensures strong dehumidification while not lowering
room temp
Turbo Mode - Intense cool or hot air is discharged to quickly cool or
heat the room.
Other stuff that relates to cleaning and stuff.
No mention of a remote and as the Paraparaumu store has run out of
units I was unable to check what's in the box. I've rang the freephone
number and asked for an installation quote.
Spoke to a old guy in the store and he said that the unit uses old
type gas?
Thanks for all the great information.

A couple of years ago friends of mine in Kandallah installed four heat
pumps around their house. Total all-in cost: c$15,000. All of them
perform as specified but never, ever seem to give any satisfying
"core" warmth. The moment the fans go off the rooms go chilly and
having been in their house, I have experienced this for myself. They
even reverting to their woodburner from time to time for what they
ruefully refer to as "comfort".
No matter what the claimed power savings, they know they'll never even
break even on a cost/benefit basis. They also admit that whatever the
putative cost savings these will be negated by heavy maintenance and
replacement costs in a few years' time.
Get a woodburner installed. Thousands cheaper overall than a heat
pump and you can easily modify the vents so that it will burn
overnight. Manuka or similar for fuel.
Guranteed *cheap*, *continuous* warmth day and night, and who gives a
toss if the lakes run dry or the Cook Strait cable goes AWOL?
You KNOW it makes sense.

So lake levels and Cook Strait cables have nothing to do with it?
Power failure and you freeze, so first get yourself a 100% secure
electricity supply. Fat chance!
I reckon that in the majority of cases, and with a continuously
plentiful supply of a sustainable firewood resource, domestic heat
pumps in New Zealand make no sense. They are a dead loss right from
the start but who wants to be first to admit they've been had? In any
case, their increasing introduction only exacerbates the already
existing perilousness of NZ's power supplies.
People have been too easily seduced by yet another shiny, "techie"
gadget, naively deluding themselves it will deliver more value than it
actually costs. But it's really no more than an easy money-making
spin off from the hot-climate, northern hemisphere air-con industry.
A snare and a delusion. Do the maths if you dare, and do them honestly
- you'll see why soon enough.

Most nights I stop fuelling my own woodburner about 6.30pm. This
gives plenty of even, continuous cosy warmth (about 22 degC) until
midnight or later. Even over the coldest nights (down to about 0
degC) both woodburner and entire extensive open-plan area have
retained sufficient warmth not to need a re-kindling first thing in
the morning. And even when eventually re-kindled, it does so from the
still-live embers of the previous evening. What's more - it's cheap,
*silent* heating. Maintenance over the 12 years since installation
has been $$153.00, made up of:
Annual sweep - $40.00
Door rope-sealer: $70.00
Replacement firebricks: $43.00
I challenge any heat-pump owner to shut down their living room heat
pump at 6,30pm each night and still achieve the same continuous warmth
and comfort benefits over a similar period. And if they eventually
need only $153.00 of essential maintenance over a period of 12 years
with not one single failure to deliver as promised and specified
during that time - *and with their heating still performing as well
as it did when first installed* - I'll eat my words.

Then they're fools. Do they actually *know* what are the actual
environmental impacts of the heat pumps being manufactured, delivered
to, and being installed in, New Zealand?

I have lived in Dunedin most of my 60+ years. I have never known a power cut
lasting more than around 30 minutes. I do know that I installed a Stack
woodburner in my main living room in the early 80s when I moved to this
house, then began collecting firewood by every means possible. After a year
or two I decided the only way was to buy it by the truckload. I also used a
small heater for short periods when there seemed little point in lighting
the fire. Cost of fuel per year approx $750 for wood (2.5 large loads @ 300
a truck most years). I don't know what I sent on maintenance, but it
certainly needed a few bits like the tip of the cast iron box, door seal
(rope) handle and god knows what else, and then there was flu cleaning.
Stacking firewood required storage space, I had to tolerate every crawly
damn thing that decided to live in the timber, and the bloody thing created
dust in the house every time it was cleaned or even just opening the door to
refuel. I eventually ripped it out and put in a pump. In the ten years since
I have spent nothing on maintenance, and nowhere near the runnning costs of
buying wood, in fact my power bill hardly rose even though I did not use my
previous electric heater that often. It's convenient with timers and
thermostats, and the house is so much cleaner. I have since installed a
second one in another room that previously we didn't use in the winter. To
each his own - but for me I wouldn't thank you for another log burner. And
if I ever shift, there'll be a heat pump moving in the same day I do.

Get one supplied and installed by a pro....I had a look and they are
basic units, plus then you need all the bits, you might save a few
hundred....but I would not buy one, even though I could install it
myself.

Also height plays a part, not just distance...so keep both parts
within 1metre height.
The biggest disadvantage is they are single space use, so if you have
one huge room, Ok, if its a house well you have to heat it all by
leaving dorrs open....in which case it could cost you more than spot
heating....

Don't forget that many people get heat pumps for cooling as much as
warming. Moreso if they live north of Hamilton.

Here in Auckland a heat pump is uneconomic if it costs more than about
$1000 including installation, compared with a few $30 heaters.

A woodburner would cost more than $1000 to install. Therefore
uneconomic as above, unless you happen to have a fireplace already.

Another point an inverter model is easier on the compressor as it is not
starting and stopping all the time. It is "idling" for alot of the time.

I went to get heat pumps installed 2 years ago. I contacted 4 firms covering
different brand names & got them in to talk to me about my type of need and
prices. One of the firms was a joker selling a cheaper brand. He came first.
I asked every other installer if they could source and fit for me the
cheaper brand and if so, at what price. What convinced me was the other
installers saying "no", they would not source and install the cheaper brand
as they would not vouch for its quality. They would rather turn down a job
than sell something they could not guarantee. In the end I got 2 panasonic
pumps installed. Maybe you could try phoning a couple of installers and ask
them if they could source and install a daewoo for you. if so, what price
and what guarantees. If none given, consider the quality.

No idea, but I've been wondering myself on this one. I do know they
only come with 24 month warranty
whereas most of the other big players give 5 years. The cost to
install usually is about 800 dollars depending on
trades person and type of install....so for around 1800 all up seems
like a pretty sweet deal....only if it doesn't crap it.

A heat pump is nothing more than a big fridge split in two. Big fridges cost

A specialist firm is the best place to get one.
We have a Panasonic from Varcoe. They are very good with the installation
and look after the servicing.
A cheap bargain from a store is only a bargain if you know exactly what you
want and can arrange servicing.
What kind of guarantee did you get with yours? Is it still under guarantee?
I don't know about Daewoo but the Warehouse should be pretty good. What do
they say?
Goods must be fit for the purpose. There are consumer regulations about it.
If there is a fault in manufacture you have rights. Look into it before you
agree to pay anything.
