Panasonic ASHP doesn't vibrate!

[Mr Blobby]

Panasonic Aquarea installation manual says "Due to the high quality mounting system of the compressor and subsequent suppression of noise transmission, Panasonic Monobloc units do not require flexible hoses to transition from the Heat Pump to the pipe work used in the installation."  

 

This sounds too good to be true. 

What about rubber feet underneath?

 

Anyone installing Panasonic units, is it ok to install straight onto the concrete base without rubber feet, and omit flexible hoses?

Hi.  My TCAP Aquarea doesn’t have flexible connections but does sit on anti vibration rubber feet.

 

All good!!

Think the reality is most modern heat pumps don't vibrate. I have Flexi hoses, but more to allow small movement due to wind etc. but possibly not needed. It also give some assurance no noise is transmitted. Bit like buffers and glycol, none of that needed either, install antifreeze valve that reference water temperature (not air temp) your all set. All old rules from single speed compressors and fans.

If you stood 3 feet away from mine you would not know it’s running, you have to actually put your hand in front of the fan to feel the air blowing.

Fitted a good few Panasonics, and I just bolt them down to the concrete and hard plumb with copper. 
 

As above, you’ve got to stick your head in front of it to prove it’s running, but the caveat is that you design it to be relaxed, not running flat out.

 

Zero vibration or notable running sounds / nuisance. Very impressed with them for the money, and they do cooling out of the box   
 

Tres bien!

Yep, no rubber feet or flex hoses rerquired. The new m series has a separated compressor a bit like a washing machine drum so you have to remove the transport bolts when you install it. I'm soon fitting one directly onto a flat garage roof very much because of the lack of vibration.

Even if no rubber feet required the extra height they give is useful for a degree of winter snow protection .

The Panasonic’s are up on a factory plinth anyways.

I set these on blocks if the client specifically asks, also allows the typical concrete slab to go bye bye, much easier on the eye with a bit of nice landscaping around.

Hidden in the depths of the internet is the (strangely secret) release of the 5 kW monoblock in a way nicer anthracite. 😀

 

And is also a couple of hundred quid cheaper 🤔

Agreed, @Mr Blobby. That's a good improvement on the computer putty coloured one above.  I've always been surprised at how very ugly most of these units are.  I suppose the designers have mostly spent years designing units for commercial buildings & ugly is cheap, & it doesn't matter.  It hasn't occurred to the designers that their creations blight the appearance of so many homes & many people will pay more for a competitor's less ugly design.

 

Same goes for MVHR units;  Zehnder have some nice looking designs, but if I choose something else, I'll have to build a cupboard around it.

mine is hung from a wall, zero vibes.
