Second hand ASHP


Recommended Posts

Local to me there is a second hand ashp, it’s being taken out of a house that is having a large swimming pool removed. 

Im wondering if it’s worth a punt. 

 

Its a daikin unit with a split indoor outdoor setting, whatever that means. 

It’s 18kw so a big unit, it has just been serviced and had some part replacement, the service engineer said he could see no reason for it not to continue to function properly for a good few more years. 

They want £99 for it I wonder if it’s worth sticking it in for a year or two until we have some dosh to replace it.

is it 3-phase?

Split means you'll need it evacuating on removal and regassing once the  new gas lines are installed

Not a lot to add to that, except as it was for a swimming pool, is there any corrosion.

Any ASHP has a gas circuit. The difference is if it is air to water in the main unit. A split is normally one that has the gas /water heat exchanger in the house and connected with small bore refrigeration pipework. 
 

If it is a true split then it will be £3-400 to get it decommissioned and moved, assuming the gas is readily available as a lot of the older gasses are now being phased out. 
 

Find the history and the part numbers and lets have a look.

Do they all have a gas in them or is it just cooling units. 

They all do, just like most fridges.  It is how they work.

Cross post with PeterW.

 

Basically they have a gas pump in them.  As the gas is compressed, the temperature rises, as it expands, the temperature cools.

There are heat exchangers to either take from the hot side or the cold side depending on what you want.
