I've heard that the guys who install heat pumps more often than not end up sniffing your undies.

there seems to be some common mis conceptions about heat pumps.All they are is a fairly efficient way to heat a space.They can produce more heat than the ammount of electricity they use.The ultimate heater i think would be a modern efficient wood burner where the firewood was free.All the most modern log burners,wood burners,pellet burners draw the air they need for combustion from outside the space they are heating.Our pellet burner is mounted in the old fireplace and draws the air required from the old fireplace cavity which in turn is supplied from the vented flue.The pellet burner is sealed from the room.

Correct me if I am wrong.'pellet burner is sealed from the room'
your pallet burner takes air from the outside, burns it, the exhaust goes out thru the flue,
heat(and I suppose light) is transferred through the walls of the unit into the room.
the reason I ask is that I have an exiting fireplace which is a better light source than a heat one.
I could replace it with a pallet burner with ducted air from the outside - so its not using the warm air from the room
I was contemplating getting rid of the fireplace altogether - its in the middle of the room

A mate has a pellet burner, loves it.
I like the idea of them, and they can put out a lot more heat than any electrical item, and they auto-feed.
The only reservation I have is availability of the pellets, they have been fairly reasonably priced in the past, not sure what they cost now and I'm not sure how many suppliers there are keeping each other honest...

Do you even know the difference in types of heat? You ever heard of terms like "radiant" "convection" "conduction"?
You say "they heat or cool the air in the room" what happens when that air escapes? that's right the heat escapes with it! & you say I have no idea... Fucking imbecile; Maybee you should try thinking sometime might do you some good.
Problem with most of them is they require electricity to run

Heat transfer ducting can be weird. Some places it works, others it doesn't. Ya gotta know about static pressure and how it effects the flow,outlets,any number of things. It's more complex than just a tube and a fan.
Bogeyman
Not a lot, just for the fan and the pellet feeder.
But yes, if "good foe a power cut" is high on your list then probably not the right tool for the job.
Having said that the huge log burner we had in the last place went from a comfortable quarter throttle to full throttle when the power went out and still wasn't keeping up.
Massive area to heat though.

6KW is what I put in an average size lounge dining. It's not big enough for a modern open plan living/kitchen area.
For those I like to put in a cassette unit. They get a great spread of air and can be central. They're a cunt to retrofit though, most times we're putting them in new builds.
There are so many options available, there aren't many applications that can't be worked through. But it's not always the most cost effective.
I'm not a fan of putting a big log burner in to heat a whole house. The room with the fire tends to be too hot before the rest of the house heats up. That's my reason for thinking a ducted air con system is boss. Whole house at whatever temerature I want, controlled by a phone from anywhere in the world.

I'm aware of the different types of heat, though from the context I'm not sure you know as much as you think you do.
Anyhoo. A high wall heat pump is designed to warm a single room. So that's what it tries to do. The reason it needs to keep coming back on is thermal loss and the tempered air escaping. That's why we take window area and a home's insulation into account when quoting a job.
I'm pretty good at my job. I went to a job for a guy we contract to and refused to do the install. The KW output on the unit was possibly, but in this room (three stories tall and 80m2 floor area) a single high wall was not going to do the job at all. Customer was stoked, we discussed his options and came to the same conclusion he had when he got the salesman round. I don't make more or less money based on the number of installs I do. That affords me a moderate of integrity that a lot of installers don't seem to display.

Our house is nine years old and only 70 sqm..the 6kw heat pump is big enough.

Is it a high wall? 6KW might be doing the job, but I'd have gone bigger or use two smaller ones.

We had both in the last house. The burner was 32kw iirc, and I messed with the original DVS system so you could pump air from the top of the 80sqM living area to anywhere in the house.
I remember installing the last pot belly the local foundry ever made in a lockwood we had in Normandale. That first winter we'd sit there looking through black storm clouds out over the harbour wearing fuck all, with the windows and doors onto the deck all open and the stove a lovely straw yellow around the grate. The stainless flue bright red at the stove, fading to cobalt blue at the roof.
When it comes to combustion of any sort a bit of overkill never hurt anyone.

The pellet burner is an "insert" type
the pelletburner sits in a cavity and the cavity is(mostly) sealed from the room.the cavity is vented to outside via the the double walled flue .The pellet burner heats the air of the room but it does not use the air in the room for combustion.The body of the pellet burner also gets warm so there is some radiattion but most of the heating is done by very warm air blown by a fan The air of the room is continually warmed by the pellet burner

mitre 10 and placemakers have pellets,and "ablaze" have pellets.they seem to be all different suppliers.Alternatively you can buy pallets(a tonne) at a time .I buy ten 15 kg bags at a time for about 11 bucks each.each bag lasts about 3 evenings heating our poorly insulated 40 to 50 sq m lounge dining room of a typical 50s bungalow.
pros are push button start, automatic regulation,can be set to come on automatically,relatively clean and simple to keep fuelled.Cons are need electricicty,the fans always make some noise(think of a fan heater on low),they need to be cleaned of very fine ash,and they are complex compared to a woodburner.They are supposedly quite efficient but you pay to play.ours is a quite modest 6 kw unit and being an insert maybe not quite as good as a freestander
edit main con i think is they are more expensive to buy and to install you need a new or close by power point.One of the suppliers early on in our search suggested it would be quite easy to have a pellet burner run of a battery for security of operation during a power cut.
