One of my drinking buddies has mentioned a couple of weeks ago that he
had his heating and hot water system upgraded by the addition of a heat
pump. He seemed to have difficulty explaining how it worked so today I
went to have a look at it out of curiosity. On the side of one of the
components was www.magicthermodynamicbox.com so I was immediately a bit
suspicious.

It is essentially a huge fridge evaporator panel on the outside of the
house which serves a heat exchanger for the hot water, and what looks
like a dumb box adjacent to the boiler, which has feed/return to the
boiler and the radiators. They have also put thermostatic valves on all
of the radiators.

I suspect that he has been right royally shafted but there are some good
reviews on the net

(only joking there are twice as many saying stay well clear of this sort
of stuff, the best one being)

I was too embarrassed to ask how much he had paid, but bear in mind we
have no mains gas and his current fuel supply is oil, the existing
boiler, which hasn't been touched, is many tears old.

Does anyone have any first hand experiences of these "magic boxes".
