@ProDave given the current good value of the LG Therma V units (£2700 inc vat for a 9kW unit: https://www.tradesparky.com/solarsparky/heating/air-source-heat-pumps/lg-hm091mru44-therma-v-s-9kw-heat-pump), would you say they represent a good ASHP option, given that they are a known brand and not the usual generic chinese offering?   If that price includes a controller, that's a decent deal.
