Absolutely excellent service. After receiving over the top quotes from 2 other companies called hotwater.com.au. No call out fee, I was given a quote over the phone, literally thousands cheaper! Hot water unit was installed the next day. The plumber they sent was on time, very good to deal with and professional. Even though the installation took longer than expected there was no extra charge. I can’t recommend this company highly enough. Quality service with affordability are a rare thing these days, hotwater.com.au gives both. Well done

We had iStore 180 installed one week ago, Hotwater.com.au did everything they promised. Happy with the price, product and service.

Had a Reclaim Heat Pump installed by Hotwater.com.au in February. Brilliant experience from start to end. From initial contact with Natika with very competitive quote she had installation fitted into our tight schedule. The communication by her was second to none. The installation team were great and fitment was perfect. The Reclaim Management team from interstate were also very impressive. The System is so quiet and hotwater supply is better than ever and so inexpensive to run, but expected from the top of the range system. After a very disappointing dealing with another 'Adelaide Heat Pump' company over 4 1/2 months it was so refreshing to deal with Hotwater.co.au . Totally RecommendThankyou Natika and team.Cheers Morgan and Kerry

Helpful staff that are clued up on rebates/schemes to get some money back. I found the heat pump installation smooth, 180lt good size for 3 people, even with long showers and hot water is quicker than instantaneous hot water. It is more expensive initially, but should pay for itself in gas savings.

This firm communicated well with us as residential clients throughout the process of enquiry, site inspection, quotation, installation & commissioning, payment and certification. The site-inspection rep and the installation crew arrived on time and were affable and respectful of our property.Overall, this firm has a professional approach with experienced procedures and personnel for its administration and technical operations. And the firm's staff have faith in the products they sell and install.If only more trades and services operated like hotwater.com.au!

We chose Hotwater pty ltd to install an istore HWS after doing a lot of product research and reading lots of reviews on the company. The correspondence we had with the company prior to purchase and the dealings we had with the tradespeople (plumbers and electricians) were all repectful and friendly.I can genuinely recommend this company to others.

Well done all.Petar.

These guys were by far the easiest to get a system from, I had spent weeks trying to get quotes before finally coming across these guys! Natika had an email quote to me within about an hr with exactly what I had asked for.
Installation was easy the guys even watched the dogs while I went to school drop off after moving into the property only days before install. 😀
