But, it has to be said, that the flow can be limited if other taps are running simultaneously. That said, it provides almost instantaneous steaming hot water, literally on tap, whenever you need it.
There is no storage cylinder to heat first or to run cold and there are no tanks to find space for. So ask yourself if there is such a great demand for simultaneous hot water around your home. If the washing machine, bath and shower aren’t competing in every room, combi boilers really could be the perfect choice.
