Heat pumps are shit!

[Voltaire]

I supply and install Mitsubishi Electric ( as opposed to Mitsubishi Heavy Industries). They are very good if sized and installed correctly.
Older heatpumps run on R22 and compared to the newer R 410a and are junk.
I ( foolishly) when working for York bought Luxaire (Warehouse) units....they are rubbish...anything below 10 degrees and the heat output is pathetic.
Still...they were cheap but you forget the cost when something does not work properly.

Mitsubishi....I have measure 50 degrees plus air off with a frost outside.
Installation: make sure your installer at least has a vacuum pump...if not it voids the warranty.
Pipe work should be pressure tested and vacced to under 500 microns to ensure long compressor life.
Larger units should have a dedicated power circuit.
Only a registred electrician can install new fixed wiring, and supply a Compliance Certificate.

Thanks for that detailed reply. I'm quite sure ours is bigger than we need for the area we're heating but one side of the room is just glass (wall and part of ceiling) so maybe it's fighting all that single-glazing.

Oh well, soon be summer...

It sounds like you have a unit that is to small for your needs.....

Ooeerr that's a bit personal init?? The size of Molly's unit is a private matter surely.....

Yeah, well, I think all men think their unit should be bigger.
More power and all that.(think Tim the tool man)

Sort of like cc envy Ive always wanted the bigger model. But if you aint got big enough heat pump, from what I understand you will feel its inadequate.

Exactly.
You must feel sorry for those that feel inadequate.
The pointing and laughing is so cruel. (but fun)

The only thing that you can brag that is small, is your Cell Phone.

heats pumps work great

ital all about location
my m8 got his compressor unit installed in his garage no drama neva defrosts there

My Uncle had to shift his out of the garage, it kept on freezeing his cars.

Just put in a Panasonic E12 5kw to assist a log burner and for autumn / spring. Best thing we ever did.
$2050 all up pump $1550 installation $500

[javawocky]

heated grips here, don't cost anything to heat...

No seriously, got my quote from MHI agents and waiting for my install in the middle of next month

Should not defrost as dis is da Dorklands

We don't feel conned,we really only had the heat pumps installed to cover the between season periods!

Like when it's not worth starting the fire but yet too cold not to!

So far they have excelled our expectations and not much change in running costs.

I think you actually need to know something about what you're commenting on before casting aspersions... oh, no... wait! This is KB! As you were...

Heat pumps rock. Got one installed earlier in the year. Now we don't even realize it's winter until we go outside. Costs about $100-150 per month electricity though at 18C 24x7.

Put. A. Jumper. On.

It's quite amasing to see the sudden uptake of heat pumps in NZ. I went the other way and had underfloor heating installed during major refurbishment. Couldn't be bothered reading the instructions so just flicked the switch to a nice a toasty house. Just got my power bill... $1100.00. Ouch.

Max Preload, when you ask for info after telling them,the supplier,waat you expect and that waat you expected is not delivered one has every right to make comments! and when you find out that the goods supplied have been dumped in NZ from Aussie and said suppliers to one of our bigger DIY and building suppliers has vanished! i expect that there is a body that should and could bring power to bare on the retailers to honour the warranty and make sure that waat they have claimed the said pumps can do.
