Rip off Britain was on last night on bbc 1!
It featured a whole new build housing estate with NIBE heat pumps that were supposed to be cheap to run! Long story short, they were costing a massive amount to run in electric usage!!! The tenants could not afford to turn them on!
They were all ripped out & gas boilers fitted! Everyone's happy again...
BBC News - 'Efficient' heating system left families with big bills
There was a lot of complaints up & down the country about these systems... I don't think they live up to there claims!
On another perspective, in years to come who is going to maintain these things? They will defs be a lot more to repair than your average gas boiler! How much to replace a compressor on those big outside noisy units?
