Hi and thanks for replying.
There was never any data on the heat pump @Ryangleeson, that is my issue. I was just wondering if maybe inside heat pump on the compressor or somewhere else it would be marked? It is a new build and the builder says it is an 8kwh but obviously my trust in them isn’t great especially with Daikin saying the hydrobox, which does have data was sold with a 6kwh pump. That was sold to a plumber so obviously they can’t say what was actually installed. Hope that helps.
