Ravenheat CSI Primary
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.
I have installed several CSI primary boilers in the past and I am not impressed with the alloy secondary heat exchanger or recuperator several examples I have seen do not seem able to withstand flue gas/condensate corrosion I have photos of one such heat exchanger that has suffered severe corrosion , the boiler was 2years old .If any one wants to see them I may be able to e.mail them I also still have the heat exchanger .NOT IMPRESSED !
