Testimonials

Excellent

Based on 95 reviews

They did an excellent job replacing our leaking hot water system. The technician was very polite and took the time to explain the issues with the previous installation and what needed to be corrected. The new pipework has been neatly arranged, and the system has been installed with great care and attention to detail. I’m very happy with the quality of the work and the professional service provided.

Philip Wen

Hot Water Sydney installed my hot water system back in 2013.
The job was very difficult in a confined space, but Barney, the technician, completed it professionally and without any complaints.

Since the installation in 2013, the hot water system has been running smoothly right up to today, with no problems.

Excellent workmanship, reliable installation, and long-term performance.
I highly recommend this company and especially Barney.

Celine Nguyen

I got my solar hot water system removed and reinstalled for roofing purposes 2 months ago and I forgot to leave feedback.

I called and got quote quickly from Ingela without any inspection which saved a lot of time, the price was better than all other places quoted me who had to go on site to quote.

Barny (not sure if it’s his name) came on time, did the job well, efficiently and also helped clean the solar panel.

If I need help in the future, I will definitely come back. Thanks team!

Chris Jones

Called for a quote one day and our system was installed the next. Great advice on what system to use and efficient installation. Answered all our questions and would highly recommend.

Lisa Todarello

I have been using Hot Water Sydney since they purchased the business a couple of years ago. My experience with the previous owners was great - a hard act to follow. Danielle has retained the previous staff and the great experience continues. Fantastic, friendly service, efficient trades and very easy to deal with.
