Professional and Efficient Hot Water Heater InstallationI recently hired HotH2O to install a new hot water system in my home, and the entire process was seamless from start to finish. They were quick to respond to my initial inquiry and provided clear advice on the best options for my needs.The installer was arrived on time and completed the job efficiently without any issues. They were respectful of my home, ensuring that everything was neat and clean when they left. The quality of their workmanship was outstanding, and the system has been running perfectly since it was installed.What impressed me the most was their excellent customer service & high quality work. I would highly recommend Lee / HotH2O for anyone looking for a professional and reliable hot water heater installation.

i didn't get to try this company as i needed to get a hot water system and also found them after an email a day later. what impressed me the most about this company is that you can book online and they have times and you can see the prices which is very rare to find! next time I will consider this company for my next hot water system or even too recommend them

Couldn’t be happier with Lee. Great communication and intimate knowledge of our type of hot water system. Punctual, professional and personable. Puts most tradies to shame with those qualities.

Lee’s expertise and experience was very obvious from the first interaction. we had another company come before HotH2O and they said we needed to replace the whole system and they couldn’t repair it. Lee asked a few pointed questions, found the problem in no time, repaired it and even gave some advice for the future.

The owners of Our house just had Lee from Hot H2O replace our hot water system with a new heat pump unit, fantastic, would highly recommend using Lee to do any work, turned up on time for the quote and again on time for installation, very professional, nothing was any trouble, cleaned up like he was never here, worked his fingers to the bone to get the job done and it was awkward because the old hws was a gravity fed unit in the roof cavity with the world's smallest and worst placed manhole, he never complained and busily worked away to finish the job, he earned and deserved every dollar that day. Honestly wouldn't use another Plumber after seeing his work ethic.

Lee installed our hot water heatpump and the process was very smooth from beginning to end. He even promptly responded to a question I had a few months after the installation. Thanks for the great service Lee.

Wow - What a great service from our initial phone call, to final install from Lee and Kimberley at HotH2o. Our solar hot water (15 yrs old) system crapped itself during a winter frost - and I contacted Lee from HotH2o (due to other reviews). He came and gave us some options for a new hot water heat pump - and answered all our Q's. Great price - and a terrific install (with fab help from wife Kimberley) a short while afterwards to fit in with us. Also removed our old system tank and solar panels.Can't recommend HotH20 enough. So, so happy to get such a great service and product. Give Lee a call if you are looking for a hot water heat pump system. You wont be sorry.Cheers - John & Fiona from Katoomba

I am so pleased to have found Lee!. I booked him on the basis of his other good reviews and he's the real deal. I had no idea why my close couple solar hot water stopped working properly and I feared the worst. Lee came today and got straight up on my roof and within 10 minutes found my faulty thermostat. He replaced it with the correct one straight away. He also forwarded photos of my panels as my tree is shading the solar panels so I can get some branches trimmed. He was really helpful in explaining how the off peak booster worked and showed my the switch on the board to switch it off if I didn't need to use it which saves me money. If you want someone honest, reliable, very fairly priced and very experienced with solar hot water don't hesitate to call Lee at HotH2O :)

Lee and Kim installed the Heat Pump Hot Water system for me, they are professional and did a very neat job.I highly recommended Hot H2o!

Installed Hydrotherm heat pump from them. I used to have old electric HWS which costs a lot to run. Happy with Hydrotherm as I can see this consumes significant less energy. They are well across government rebate (ESS&STC) so they provide the best price & quality work. Highly recommended.

Our 19yo gas hot water system gave up on a Friday afternoon. We range Hot H20 and Lee came out first thing the next morning. Since we had just switched on solar Lee ran through options (gas vs heat pump), gave me time to review the systems and had a new Aquatech Heat pump installed by 10am. Price was competitive with everything I had seen online so I was really pleased so I was really pleased I wasn't getting stung for and urgent call out. Would highly recommend

Lee recently installed a new 315L Sanden heat pump hot water system for us. From the moment I enquired to the installation being completed the service was excellent. I can't recommend them highly enough. Support a great family business and contact Hot H20! Thanks so much Lee and Kim!

Highly recommend Lee from Hot H20. I rang he answered immediately. Told him the hot water at my home has failed. Yes I will check it he said. Arrived early, diagnosis of the problem 15yr old water heater no good. New replacement and piping installed in 3 hours. So refreshing to find a service technician like this. Thanks Lee. Five star service.

Asked for a quote on instant gas water heater, as current water heater didn't seem to be working. Lee came out, found the solar heating switch had been turned off!All I had to pay was a service fee. Thanks so much for your integrity, Lee. When we do finally need a new hot water service, we will be back :)

I recently purchased a Sanden heat pump system from Lee at HOTH2O. I can't recommend them enough. They were responsive and their communication was excellent to the extent that they let me know when they were coming down to about 10 minutes and the installation is top-notch with neat plumbing and wiring and everything fixed properly and run in straight lines and right-angles - it's actually pleasing to look at. Pretty impressive for something which is tucked away out of sight. Absolute professionals.
