renewable heat incentive - is it worth it?

Interesting article on someone who appears to have taken advantage to the maximum of the RHI initiative -but has ended up with an expensive to run and ineffective heating system !!

We claimed £70,000 in grants for heat pump, but it saved us NOTHING | This is Money

Or, put another way, "people with large and poorly-insulated house are shocked to find that it's expensive to heat".

If you have a house with a mixture of radiators and underfloor heating (as in the This is Money article) you have to make the water hotter for the radiators so your heat pump will run no more efficiently than if you had entirely radiators and no underfloor heating at all.  If the underfloor heating was on Zone 1 and the radiators were on Zone 2 then there is the potential to save money by asking the heat pump to target a lower output water temperature when there is no demand for heat from Zone 2.  But I'm not sure if my own heat pump is smart enough to be able to do that.
