We've got a ducted Panasonic and haven't had the gas related issues. Have only used the turn off timers and they have worked as expected. I remember when reading through the brochures that the panasonic woudn't blow cold air (on heating mode) until it was ready - noted as a feature... So maybe its a case of this feature annoying you!

The Toshiba highwall which gets used a lot on timer mode works great. When manually turned on, it can take a couple of mins (normally) to start doing something.

I understand the unit seems to have a ten minute cycle to check for temperature and adjust. This may be something that causes trouble, who knows? Also the unit has a movement detection - again perhaps something that can cause problem, even when it's not enabled via the remote?

I just think it's not accurate at keeping temperature consistent, really. What I've noticed is that it's much more effective if turned on for the whole day than only when you feel the cold.

freitasm:

I have a Panasonic heatpump. It sometimes takes ten minutes before hot air comes out. Also sometimes the thermometer in the lounge shows 18c and even though the heatpump is set to 22c there is no action - or very slow air movement. If you then set to "Powerful" it sometimes takes a few minutes to blast a tornado - or sometimes time passes and nothing changes.

Ours is set to turn on at 6.30am (we get at 6.45am) and sometimes the lounge is nice and warm, sometimes... nothing.

It doesn't seem to keep the temperature in check really. I have tried contacting Panasonic through their website and never got a reply.

Quite disappointed with Panasonic.

I was going to post the same exact thing! No more panasonic heat-pump for me.

On the other hand we've got a Fujitsu on another room which works (and behaves) as expected.

I think the unit is designed for those who like to "set it and forget it" kind of people.

The programming seems to be too aggresive towards power saving even though the Econavi, an energy-saving mode, is turned off.

Just had a guy come and quote us for a heat pump. They only do Panasonic and have quoted us the CS-Z50VKR model, which I noticed is what the OP has. Not sure if OP is still active here, but does OP or anyone else can still attest to the current issues in this thread?

Am still going to get additional quotes, likely for Mitsubishi and Daikin, but if anyone else has opinions with the Panasonic VKR model, that will help in my decision making.

Thanks in advance.

OP here.

We had someone come and look at it, replace some parts etc but basically just said it's a fault with how they're made and he no longer installs them.

Over summer it's been fine, no issues with cooling.

For winter use I'm not looking forward to it again. Same problems as laid out in the op.

Honestly I would still avoid them, at least in a bedroom setting.

Feel free to let me know if you have any questions

I am not unhappy with my Panasonic. It's quiet and it heats ok. Still have the strange times it turns a bit earlier or later than the set clock but it overall works ok. It must be a strange algorithm...

Thanks, in that case, will see what Mitsubishi and Daikin ones are like for now, as well as compare the prices.

So I've come to a bit of a road block at the moment... Just been comparing the Mitsubishi GL and the AP with the Panasonic VKR and in terms of specs (the 5kW model) it looks like the VKR Trump's the GL and AP by a few things like better cooling/heating capacity range, sound levels, and importantly the EER and COP values. So on paper, I'd be looking at choosing the Panasonic, but am also wary of the OP issues... Hence the road block.

Guess it's time to have a look at the Daikins.

If everything still stacks up in Panasonic's favor, voice your concerns to the installer/provider and get them to assure you with respect to the Panasonic units, then if these weird things crop up, its on them to remediate (if you have the mental fortitude to struggle through what could be a pita process till solved). We have a Panasonic ducted unit so could very well be totally different, but this at least seems to work just fine.

We installed an AC about a year back..... we were going to go with daiken / Mitsubishi / or Panasonic - but installer talked us into Fujitsu (lots of bad stories but also they seem to be the most installed).

It is really quiet -- the vent opening mechanism is silent and warming / cooling starts after a couple of minutes.

If we had the issues you describe I wouldn't be happy -- definitely should talk to your suppliers.

The best heat pumps I've ever had were two Toshiba units we bought when we lived in Nelson. These replaced a single Mitsubishi unit that was fantastic but failed at about 12 years old due to an electrical fault. We had 'fusion cover', which mostly paid for the two new units.

We currently have Panasonic heat pumps. We assume they were installed when the house was built in 2010 - CS-E24GKR and CS0-E9GKE.

We had them serviced last year, which made no discernible difference to performance. Both useless. Slow to start. Not really very effective at heating - especially when it's frosty, which is when we most need them to work. Timers work accurately though.

If I was buying again tomorrow, I'd go Toshiba or Mitsubishi.

I'm the OP. These "weird things" are faults with the design of the units. They can not be remediated unless you consider replacing with a completely different unit is remediation.

I have the 50VKR model, the flap opening/closing is quite loud, ours is in open plan living/dining so not much of an issue. I definitely wouldn't want it in bedrooms.

It does take a few mins to start heating, but otherwise I'm happy with it.

Have the wifi module, so timer isn't an issue for me.
