Im thinking of installing a 22 or 24 litre per minute unit that is mountable on the wall outside - I prefer these smaller boxes to the storage units because they take up too much space (and I hear the continuous are cheaper to run long term)
I have been offered one (a bosch? cant remember) with an electronically controlled thermostat which I dont think I need, least of all I dont want to pay to have installed.
Can anyone tell me the ins and outs of these continuous units and whether I need know anything particular? And what they might cost to install? (I know they are more expensive than the storage type)
thanks.
