Can I install an air source heat pump in the lightwell outside my house? What type would fit?

Hello,

We are getting our house ready to fit an air source heat pump.  We have seen a few houses around us that have installed the heat pump in the light well at the front of the house.   We would like to do this, but want to know whether it makes sense.  We would put the ASHP on the ledge so the top would be at the top of the lightwell the depth (wall to bay window) of the lightwell is around 2.4m so room to have space behind and in front.  one side is totally open the other side will have a wall around 0.5-1.0m away.

I know there needs to be good airflow around the pump and this seems enough (and more than the places we have seen them installed in other lightwells).   Does anyone have any thoughts?

 

Thanks

    I can't see why a monobloc wouldn't fit. We have a Mitsubishi Ecodan and I think that would fit in the space.

     

    But you might prefer a split unit. There are advantages and disadvantages to both choices.

     

    Have you had a heat loss calculation done?

    Keep us updated on this installation, @moggins - it will be great to get some first hand experience documented here about what type of pump you get, how it fits and how it performs!

     

    I’ll add your heat pump badge in anticipation of the install.

    Bear in mind the silly 1 metre minimum distance from property boundary rule or it would require planning permission. Would this apply in this case?

    Thanks @nealmurphy,  we are fine and will be 1+ metre away from all boundaries so don’t need planning permission.
