Ecodan 8.5kw ASHP wall mounting,vibration and induction interference

realsurfer

Is this possible to wall mount? There doesn't seem to be a purpose made fixing kit.
I looked at the downloadable manual and it says when fixing to the ground }

Anti-vibration mountings (i.e. Tico-pad) should be
installed under the mountings of the heat pump to
prevent excessive vibration.

so I assume some sort of isolation from the wall is necessary to prevent the wall acting like a giant soundboard.

Also manual recommends placement of the unit NOT in full sun presumably because

An external temperature sensor is positioned at the rear of the air
source heat pump. Care should be taken to ensure this is not
influenced by direct sunlight.

I had hoped to wall mount the unit above head height on the SSE facing gable end of the bungalow. It is therefore likely to be in full sun.



Also I intend to install a induction hob . Is this likely to cause a problem.

Inverters, home appliances, high-frequency
medical equipment, and radio communications equipment can cause the
air to water heat pump to malfunction or to breakdown.

Thanks

I would not advise wall mounting at high level on a bungalow gable wall, two reasons, 1, not knowing how well the wall is built and whether fixing brackets to the wall would weaken it, i.e. weight and low level vibration when on full power or defrosting, 2. when in defrost mode upto 8 litres of water can drip from the bottom, thats why they are normally sited on a gravel bed with a soakaway or over a drain/gulley. if a condense tray is fitted, it will need to have drain tray heater to stop it freezing up.

Alternatively the unit will be mounted on the concrete path that follows the perimeter of the house. Would you recommend any sort of anti-vibration pads in this case. I haven't found any pictures of Tico-pads except a diagram showing use in fixing a lathe to the floor.
I remember the installer mentioning core drilling through the path for a soak away. I didn't realise it was such a quantity of water.
Thanks for your reply.

Hi mark, a selection of mountings here http://www.ryanairconspares.com/conditioning-brackets-antivibration-pads-c-5_95.html?osCsid=mveckkta63qlk4o8sb35pqcnn4

Albyota, can you also recommend flexible water pipe connections?
1 inch bsp or similar bore pipe is still quite rare in the UK that is specified to ? 60+ degC

The ecodan comes with antivibration pads that work fine at stopping vibration. Also, you can buy some rubber plugs that you plug in the holes on the bottom to channel all water out a single outlet. Then connect some plastic pipe to that outlet and channel it wherever you want. Cost about £14 I think.

Thanks everyone,
the reason I asked about the anti vibration pads is because the manual I looked at specifically states that they are not included (even though they recommend them) Maybe this has changed.

It should be mounted on the anti-vibration mounts, these are NOT
provided with the equipment

and

Anti-vibration mountings (i.e. Tico-pad) should be
installed under the mountings of the heat pump to
prevent excessive vibration.

For the air to air (air conditioning systems) this may work OK, but the Ecodan when in defrost mode can discharge up to 8 litres an hour, and when its minus 2 degrees outside this will freeze instantly and if the holes are blocked up and chanelled through a pipe...the pipe will also freeze.....best not to bung up holes and to mount on floor over a gravel bed and soakaway.

I bought mine about 3 years ago, so guess they've stopped shipping them. They are only about 4mm rubber thick washers, about 1.5inch in diameter.

No, it doesn't freeze instantly, it can be channelled away quite easily. It is currently about -4degC in the SE where I am. You don't have a long pipe, just enough to take it away from beneath the HP, with of course a gradient. Before I moved mine, I had about a 1m run of 40mm plastic pipe, no blockage problems at all for the last 3 years. I moved it this summer (due to noise reasons) and haven't sorted out the drainage yet, so the ground below it has a nice sheet of ice on, but none in the discharge channels and has no impact on the operation.
