SOLAR HOT WATER SYSTEMS

ABOUT SOLAR HOT WATER

Solar hot water systems work by pumping water through the solar panels during the day, where this water is then heated by the sun and stored back in the tank for later use. If not enough hot water is generated (for example during winter) the systems will usually have a gas or electric boost kick in which will heat the tank.

Being powered mostly by the sun, solar hot water systems are some of the cheapest systems to run, and can provide around 6 – 9 months of solar generated free hot water per year!

Due to their high level of energy efficiency, solar hot water systems are eligible for some of the most generous government rebates available to SA customers. While this does take a significant portion of the initial outlay off of the consumer, solar hot water systems do still tend to be one of the most expensive units in terms of out of pocket installation cost.

Excellent service. Right from the initial online enquiry, which prompted an immediate phone response, the consultant listened to our needs and a new system was installed the next day, super quick and very professional throughout. Highly recommend.

Fast quote, fair price, excellent value and they happily answered my sometimes annoying questions. Everything was included in the quote, and the workmanship was outstanding. They even came in under the quote as the remote couldn't be installed.
Absolutely will use again, and highly recommend for all.

We had been planning to convert our home to fully electric, when our gas HW system gave up and made the decision an urgent one. Natika was amazing, explaining how the rebates worked and offered us a payment option that suited us. We now have a beautiful new heat pump hot water system, have ditched gas for good and a sleek induction hot plate to replace the gas stove. Thank you 😊.

Response from the owner:You're too kind Jacqui, it was my absolute pleasure! 😊 have a lovely weekend

One needs to do your homework properly to get the best value for money. We have done that. The best company to supply the product, do ALL the rebates admin, installation of our iStore heat pump including the plumbing as well as electrical work AND removing the old heater… all this in a few hours. That company is Hotwater.com.au. Real professionals in Adelaide. Don’t look further.
It’s now two weeks later and every bath and shower is perfect. Thank you Hotwater.com.au.

Response from the owner:Thank you so much Barry for your kind words and incredible review! I'll be sure to pass this onto the team 😊 it's been a pleasure to help.

David Dickinson

Another five star review! The service from start to finish was amazing. Had a temporary unit installed to get us through the weekend when our old unit died and then the nicest crew turned up promptly on Monday to install the new iSolar unit. Very neat and tidy job, everything fully explained - couldn’t ask for a better experience.

Response from the owner:That's wonderful to hear! Thank you so much, I'll be sure to pass on your kind words to the team 😊 have a lovely rest of the week

Vicki Minge

The hotwater team arrived at the agreed time. The workmanship was high quality and they explained the functions of the unit. The communication from the office staff was excellent and they negotiated the government rebates for a great price.

Response from the owner:Thank you so much Kimberley, so glad we could help, and get it all done under the Australian Gas Networks priority service program. It's been an absolute pleasure, have a wonderful week!

Phil Halliday

Would like to say thankyou to the guys from Hotwater.com.au and also from Ohms Electrical for an absolute top installation of both an IStore heat pump hotwater service and Bosch Induction cooktop, better tradesmen I'm yet to meet. Thankyou so much.

Response from the owner:Thank you so much for your kind words Phil! We’re thrilled to hear that you had a great experience, it was truly our pleasure. We appreciate your feedback & hope you have a wonderful week 😊

Scott Barnes

The team were fantastic after the heat pump hot water at my parent's house broke down, i got a few quotes with different options within half an hour, the job was booked into their next availability and they turned up on time, cleaned up and everything was working perfectly. Thank you Natika and team, would highly reccomend.

Response from the owner:Thank you so much Scott for leaving a review, we really appreciate it. It's so wonderful to hear 😊 have a great week!

Daniel Maheras

Great experience dealing with hotwater.com.au, I had several questions about how the transition would work to disconnect our existing gas and install an Istore heat-pump to run off our PV system and all the staff were extremely helpful.

Even though it took me awhile to finally commit they were able to redo my old quote quickly when I did decide to go ahead.

Quote was extremely competitive and everything was clearly written / explained. The 12 months interest free Zip option was also a nice touch.

It’s been a few weeks since install and everything has been working perfectly, I look forward to seeing the savings and knowing that I am having a positive impact on the environment at the same time.

Response from the owner:Thank you so much for sharing! We're thrilled to hear that you had a such a great experience with us. It was a pleasure to help and we hope you have a fantastic week 😊

Lyn Harvey

Very helpfull man on the phone. Happy with quote and installation.

Robert Annesley

We are very happy with the unit. Liam and his offsider (sorry name escapes me) were friendly and did the job in a professional manner. They cleaned up well and explained the workings of the heater

Response from the owner:Thank you for your review, that's great to hear! I'll be sure to pass this onto Liam & Braeden 😊 have a lovely rest of the week.

Ken Crawford

Supply and installation of new gas hot water system was all done in 24 hrs from initial inspection on old faulty appliance. Excellent service.

Response from the owner:Thank you Ken for leaving us a review, it's great to hear and we really appreciate it 😊

Bev Harvey

The technicians arrived on time. They asked if I wanted them to remove their boots before walking on the carpet. They worked steadily and efficiently. Due to the age of the heater they advised me to purchase a Co Meter. I have followed this advice ! I am very happy with the service given !

Response from the owner:Thank you so much Bev, that's excellent to hear! I'll be sure to pass this onto the team 😊 have a wonderful week!

Pamela Lyon

Customer service second to none. Decided to buy a heat pump and landed in the best possible position for this costly purchase, starting with hotwater.com.au's informative website. Purchase and installation (thanks, Mark and Liam) were so easy and professional. All necessary documentation followed from Natika in the office, an absolute gem. When hot water failed on a Saturday night due to an idiosyncracy in weekend timing for this model, Natika answered our cry on Sunday morning and, although I managed to get hot water back on, by Monday Liam was dispatched to check out the system. Total confidence this end. Thanks, hotwater.com.au!

Response from the owner:Thank you so much for the lovely review Pamela, it was our absolute pleasure to help. It's so great to hear and an amazing start to the week. Apologies again about the weekend timer. Have a lovely, warm and dry rest of the week 😊

Glenys Leach

Thanks so much for your wonderful service. The guys went over and above to help fit my new instant gas hot water system. Hotwater.com.au already saved me nearly $2000.00 for the same job quoted by others and then went out of their way to save me more by working out a way to fit the unit into the available space. I am so grateful guys.
Recommended highly!!!

Response from the owner:Thank you Glenys for the lovely review, that's wonderful to hear and I'm glad we could help 😊I'll be sure to pass on your kind words to the team. We really appreciate it, have a great rest of the week!
