Heat pumps?

[oldguy]

Lounge is 8m x 8m.

My wife dosn't like the look - says it makes her think shes living in a hotel

I agree, I hate high wall units, see them on your wall, look like your at the doctor's clinic.

Unit up in the ceiling duct it to each room. lineal grills in the lounge, smaller nice circular cone shape ones in the bed room

[hayd3n]

that's dvs, opening the windows does the same thing.

hrv!!!!!!!!!!!!!!!!!!!

[hayd3n]

expect a big power bill, my only heating is a big masport logburner, downstairs in a 260m2 two story house with 10 ft stud height plus a ceiling fan to move the heat about, i wouldnt have a heat pump if you gave it to me

neva had a bill over 180 a month for 2 years and we have a 3 heat pumps !!!!!!!!!!!!!! 3 people 20 bucks a week each for power is all good

OK- got 3 quotes in today.

Fijitsu was first. Guy didn't measure and actually said bedrooms are all the same size - so I dont need to look.

He didn't know what the running cost were (said he had one at home for 4 years but his wife paid the bills), and his mounting position was terrible. He actually suggested we put it in an adjoining room and left the double doors open as it would make the install easier and save us $300.

He was a director or the company. - and they only sell heat pumps

Fucken terrible.

Second guy was selling Mitsi's

Didnt measure, and specified a smaller unit, that when we did the measuring after he left was going to be right at the top (or just) past its usable range.

Still he had good ideas for mounting. But everything was very casual and while he gave me more faith than the first muppet, I wasnt sure.

Last guy Daikin - came, measured each wall, checked insulation, measured windows and entered that along with the aspect, number of lights, size of TV, other IT kit, number of people normally in the room etc etc etc into a application to properly calculate the heating / cooling needs.

He was also the only one who came with literature for us to read / keep and gave a written quote (others were verbal only).

He was more expensive (about 15%) more than the others - but guess who got our business.

Didnt get a change to PM Choppa as I needed to have this resolved today.

Anyone else had experience with heat pumps? I am sure they need to be specd properly.

Specifically floor mounted units versus high wall

a few people I have spoken to say its annoying to have warm/cool air blowing down from above.

Does anyone have a ducted system rather than a high wall - ala HRV/DVS duct outlets?

[merv]

We have 4 hi-wall and they are fine. Just don't mount them where you are going to sit right under them. Once the room is at the right temperature they idle away nicely.

[Drew]

Ducted system all the way if you've got the budget, and space in the ceiling or under the floor.

We've got a Mitsubishi Hypercore in our lounge, floor mounted under the wall-mounted telly. Its only downside is that it blows warm air across the floor, by the time the air reaches our couch at the other side it feels like a cool draught on our legs. So yeah, wall or floor mount, plan your air flow carefully.

first winter with heat pump.
I miss my log burner

lets start with the positives so far.
easy and clean and wife likes it because its clean and easy

now the negs,
1/ struggles when weather cooler, spends most of its time defrosting
2/ power bills up considerably
3/ I miss my log burner
4/ power out no heat
5/ cant cook on a heatpump
6/ no sitting watching the flames play around the wood (hey i am a volly Fire fighter, its research)
7/ i miss my log burner
8/ the air seems a lot drier, I wake up with sticky eyes and we don't leave it going all night
9/ I have two chainsaws in the shed with nothing to do
10/ i miss my log burner
11/ did i say i like my log burner

Heat pumps take large amounts of cash & turn it into moderate amounts of heat.
Problem with heat pumps in many NZ homes is that the homes aren't built for them, they were designed for woodburners, they breathe something which is an advantage with woodburners but makes heat pumps largely ineffective as they for the most part need a sealed environment like the Euro's quad-glazed, fully insulated, fully sealed homes.

[eldog]

I have a open fire - Jet...something

needs a lot of air flow to get going.

IMO looks nice but not a lot of heat out.

Have tried other fires (Masport) putout a lot of heat and didn't use as much fuel.
Dual burn flow path.

due to lack of cold weather haven't used it for a few years.

You should be able to turn the bottom output off. Read the destruction manual.

Your unit is undersized.

You don't have the slightest idea what you are talking about. Why have you replied with this rubbish?

Yeah, log burners need air...the stuff they draw in is from outside and is cold. So it's kinda flawed like that.

Heat pumps don't need a sealed room. That would be fucken stupid. They heat or cool the air in the room, whatever loss might occur will happen no matter what you heat with.

You're a fucken idiot

Do you know where Riverton is Drew ? hint - f'n cold....

If I was doing a new build in an area where logburners were allowed, I'd do a ducted air inlet from outside to feed the fire.
My inlaws had a setup like that and it was VERY good.

And for a lot of us, the ability to cook on a logburner when - not if - the power goes out is bloody useful.

I'm not suggesting that heat pumps are the only option, or even the best for certain areas.

It's just that when the boom started, every other guy selling them was just chucking them in willy nilly without properly speccing them. So there's a whole 'generation' of installs that lead people to think they're shit. Taking everything into account for an install, they should all but always work as desired.

Having the right size installed in the first place helps. We measured our home in total and got the 6kw system as suggested. Where we live can be as low as -4 and foggy, the heat pump get to the desired temp and then just ticks over.

Exacary my plan when we do our reno. Pull down the old brick chimney which seems to be the biggest cause of keeping the house consistently cold, knock down a wall and stick in a modern log burner drawing air from under the house rather than from the gaps in the windows and doors.
And yeah, having hot soup when the lights go out (again) is a big bonus.

Anyone want an Art Deco fireplace, original, and very good condition?

Oh, good thread. I've thought of a heat pump but without a lot of ducting in the roof it would struggle to heat my collection of little rooms I think.

Oh 2.0. I'm gonna put a fan in the air inlet so I no longer need to use my heat gun to get it roaring. I love heat guns.
