Ravenheat CSI 85b
This boiler is discontinued.
* This is a guide price for a straightforward, like-for-like boiler replacement. Installation costs will vary dependent on work required.
as I understand it the second ally heat exchanger on this boiler is the same as fitted to the CSI primary A boiler (?)we have installed quite afew of these , some of the condensate/flue gas corrosion I have seen on some of these heatexchangers is so excessive they have had to be replaced , in my opinion the ally used cannot cope , also they are not designed to be taken apart !no consideration has been given to what happens if the condensate outlet blocks between the trap inlet and the heatexchanger outlet , could wipe out all the electronics ? I've donated 2 heatexchangers to a training centre!!
