I've come across a Honeywell Smart Thermostat model number TH8320ZW1007 and details on the link below.

I currently have a standard home thermostat wired to my Potterton ProMax Combi, how will wiring this thermostat work?

Not easily. Because:

A) Its an american product.
B) Its 24v and your boiler is 230V switching. So you'll need relays and transformers.

Which puts you in the category of "if you have to ask, then you can't do".

Thanks Dan Robinson, how about this product: http://www.screwfix.com/p/devolo-home-control-room-thermostat/7164R

Will this product be able to directly replace my standard thermostat?

I have no idea - the manuals look very Mickey mouse as does the product. I presume it talks to a receiver/hub and that is wired to the boiler.

Frankly though - Either go to Honeywell for Evohome, Or Nest.
