I had taken hot water system to a gas fitter in Lismore three times who treated me as an idiot cause I kept bringing the system back. Cost over $400 in parts and still not working. Took it to grafton gas and $35 later and after being treated like a customer should be, I'm very happy with the result.

Approximate cost: $35

Spent months trying to get a gas fitter to supply and install a hot water booster. Usual guy didn't even send a quote! Finally contacted Grafton Gas. Young man arrived 3 days later and measured up the job. Received the quote the same day (amazing). I accepted the price the following day at 3pm. At 4.30pm received a phone call; would the following day be ok to do the job. Too right it was!
Two men arrived at the agreed time and completed the work within 2 hours.
Very neat. Amazing service.

Approximate cost: $1800
