Hi there,
I'm hoping some fellow Geekzoners can help.

We currently rent the place we are in, and it has a Mitsubishi Heavy Industries Air conditioner (SRK50ZHK-S)

There are plenty of the Technical guides online (67 pages), but I've only managed to find 1 user guide online.

Unfortunately, this is the Netherlands version...

Does anyone know where I could find the English version online?

What do you want to know? Most heat pumps are pretty similar. Turn them on, select your mode (heat/cool, not auto), set fan speed to auto, then ignore. Programming timers and such is different of course. MHI are meant to be good, I recall from reading reviews somewhere.

And then go back to bed for about 4 hours for it warm up the room. If in a hurry I find turning on my old style fan heater for the first hour, means you can defrost faster!

If that's your experience I think you need to get your heat pump repaired or replaced. If I turn my heat pump on it takes 1-3 minutes to get started, but within ten minutes of turning it on the room is a lot warmer - it's amazing how fast it is. My heat pump is Fujitsu Nocria, around 9kw heating.

A fan heater comes on quicker, but at the ten minute mark it's probably put out about 1/4 the heat a heat pump could.

Something is seriously wrong with your heat pump ... assuming that the heat pump is in the same room.

We've had it serviced - nothing wrong with it - technically. I've checked the consumer site - it appears to be the right size for the room. We didn't put it in (we bought the house with it). We may well replace it with a flued gas heater once the gas is connected and other renovations completed (which will knock out a wall and change the dynamics of heating the area).

The thing is that HPs are not the be all and end all that NZers seem to think they are. They are, after all, air conditioners (and ours worked very well in that regard the 2x over summer it was warm enough in Wgtn to turn it on with cool mode). IF you need an AC in Auckland or somewhere - get one - but there are better options for the rest of us.

What make and model is it? What's its heat output? Based on what you've said it really does sound faulty.

I disagree with your assertion that they're only good in Auckland. We're in Wellington, we have two heat pumps, they heat the place very well, very quickly, and relatively cheaply. I have a 10kw Fujitsu Nocria and a 7kw Daikin in the kitchen / dining area. I have a well insulated 100 year old home - as well insulated as these old places can be. After being unheated for 10 hours while we're at work it drops from say 20 to 16 on a really cold day, an hour with the heat pump on and it's back up to 20. It runs throughout the evening to keep things warm - the newer the house the better the insulation the less time it's on.

The drawbacks of gas include the byproduct of burning them is carbon dioxide and water, high humidity causes mold and makes it more difficult to heat the place. Also you have to pay a daily charge for gas, so you need to have water heating, home heating, etc on gas. My Mum always used to put a bowl of water in front of the gas fire because it was meant to dry the air out... quite the opposite!

We have a 4kw one thats about 12 years old, thats heating a 35sqm room and it takes 3-5 mins to start up in the morning, and then its noticeably warmer after about 10 mins. the thermometers in the room say it takes about an hour to raise the temp from 12 to 20 degrees.

i honestly think your doing something wrong if it takes that long.

Mode to heat, temp to 20 degrees, fan speed to auto, up to you if you use eco or not. done.

Where do the rest of us live?

A "standard" domestic air source heat pump can extract useful heat down to about -5C external temperature.
Cold climate heat pumps can cope with lower temperatures.

We have a clapped-out old Fujitsu that heats a large room in an old drafty house from 10C to 20C in 15 minutes in the wet windy Wellington winter.
The down side - it makes a lot of fan noise while doing it, but settles down when the room is warm.

It's a Carrier with a 5kw heating output (apparently) It was installed in 2012. I've had it checked nothing wrong with it. I believe it's not the best of brands - but frankly if I'd paid for its install I'd have been making a claim against the retailer - it's clearly not fit for purpose.

Plus even it was a fantastic unit - it wouldn't really work in the L-shaped space - it's installed on a nib wall facing the lounge. We've just discovered that unflued gas heaters (CNG not LPG) - still have a short length of hose which attaches them to the bayonet. So a gas heater can be easily picked up and turned around 180deg to heat the kitchen area in the morning, and turned later on for the lounge. Plus we get the wall space back and the exterior spot near the back door.

Oh and gas is quite a lot cheaper - the unit is a bout $1000 - and given that we will have a gas fitter on site when we install gas hot water - adding another few meters of pipe and bayonet is very little extra cost.

We had a wooden 1947 ex-state we renovated in Khandallah a few years ago - the only heating in the large living room, with big windws, single glazed, no curtains, was a small unfled unit - it did just fine. No damp, no condensation. We had another wall heater - apparently no longer available - which warmed the bedroom part of the house (it was in a corridor).

Plus in the summer you unplug the heater and put in a cupboard - no dedicated wall space required.

I would never run an unflued heater in a living space.

Why not back the car in and run that for warmth?

To get back to OP's topic, I can translate bits of the manual for you if you wish. Not all of it, that's way too much, but if you have specific questions I can relay the answers.

Also, if you go through the manual you can probably get a sense of what different sections are about from the illustrations and maybe some of the words. What do you specifically need to know?

I have a 1935 brick house in Dunedin with only ceiling and floor insulation. Heat Pump heats this place up just fine in no time at all. If you can't heat your place up with a heatpump either it's undersize, not working properly or not being used properly. Agree with not using an unflued gas heater. Why would you want to add a tonne of moisture to a house that already sounds hard to heat.

I have been doing it for years. It is the only practical solution for my work room. I used to run a dehumidifier as well but repairing a wall that was letting in damp made the room easier to heat do I don't have it keep it turned on so high and the dehumidifier is no longer necessary. Not saying everyone should do this but it has worked well for me for a very long time.
