Fault Diagnosis

We are unable to help with fault finding on your HIU unit. This is the job of your plumber or HIU engineer. A general fault finding guide for HIUs is provided in the DHW and Heating tables below which may be helpful for diagnosis of faults.

You may also find the third party videos here useful to you. These are not endorsed by Stockshed, they are intended to be tools that may assist the reader here.
