I’m not saying it can’t be done. But a larger heat pump and replacing all radiators drives up the cost, there is not always space for a bigger radiator, (and water tank), and while higher flow temperatures are possible, it tend to reduce efficiency. Sometimes it’s just not worth the investment, not helped by the big gap between gas and electricity prices in the UK
