Cost of a function of heat demand and unit price of electricity.

I've installed a few and can't say I'm impressed, but equally, they have not been any more problematic than any other cheaply produced appliance.

It's just a length of copper tube with a heating element wrapped around it and some hastily cobbled together circuitry to control temperature, pump and safety.

I have carried out a few repairs on them and usually the PCB, they are easily replaced but very expensive, they seem to work Ok just really expensive to run, the installation does not look very good though and a few problems with it, no supposed to solder onto the boiler tails, should only be compression or push fit.
Also I cant see any way the air could get out of the unit , it should have an automatic air vent at the highest point, never directly above the unit though.

They always strike me as the last option if nothing else is possible
