ASHP

[nod]

We are just having the Sap done 

A question that has just been asked is 

What ASHP do you intend using 

I’m presuming the ASHP will have to be sized for each house 

Is there any particular brand or type to state 

I know our previous sap was quite specific as to which gas boiler we would use

Are you looking to max out the SAP, (100+) or manage the SAP alongside other things? By which I mean, for instance, if you want any cooling from the ASHP then specifying one that is reversible can damage your SAP but will allow cooling, most are reversible after purchase, so no cooling for max SAP but after you move in you may feel you want it!

Thanks Mike 

I was quite surprised when the sap guy pointed out that cooling is bad for Sap 

We are looking to max the sap but as with the first build  we are determined not to have PV

We went through a similar process a few months back. 

 

It was calculated that we required a 8.5 or 9kw ASHP for a 160 sq m property with no PV. That's for underfloor heating and a 200 litre hot water cylinder.

 

We are leaning towards an Mitsubishi Ecodan.
