I am going to descale the heat exchanger to increase the flow rate of this boiler. ~The DHW has a really low flow rate and does not fire up when tap is turned on.
When heating is on, heating is good, and water is hot.
Whats the best way to descale it, and will there be washers that need to be replaced.
Thanks
