I have a communal gas HWS in the building in which I live, and have noticed a marked increase in the hot water component of my bill over the last two quarters, despite very little change in hot water consumption from the same time last year.
There is a significant increase in the “conversion factor” which seems to be the culprit. What can I do about this, as I don’t really understand how and why this happens. Is this something like going into a petrol station and filling up from a 91 octane bowser, but getting charged 98 octane prices?
