What is hybrid hydronic heating and cooling?

Electrification of homes has introduced hydronic heat pumps to system, which are able to operate in both heating and cooling mode. Most commonly due to the expense and heat pump limitations hybrid gas and electric options are the best solution.

  • A heat pump with gas boiler backup are installed to a common buffer tank
  • Heat Pumps function when solar energy is available
  • Heat Pumps are highly efficient on mild to warm days
  • Gas boilers ensure adequate temperature on the coldest days
  • Gas boilers are more efficient on the coldest days when heat demand is high

What sets hybrid hydronic heating and cooling apart?

Hydronic systems circulate water through pipes to help control the climate of your space. Here, water is either heated or chilled at source, then piped through coils, transferring heat or cold into the space via natural convection and/or heat exchanger units.

Quiet, clean and efficient, your hydronic system can also run using solar.

Hybrid hydronic systems use the heat pump to provide heated water efficiently while solar energy is plentiful and the cool weather is still mild. When it becomes very cold and when demand is high the gas system kicks in to ensure comfort is maintained.

Are you running gas heating or cooling, and open to a more sustainable alternative?

We’ll help you cut the noise and understand your options at an entirely obligation-free glance. Give our friendly team a buzz today on 1300 137 567.

Hydronic Heating Cooling System

Is hydronic heating and cooling right for me?


A healthier solution

Ducted central heating systems can turn into breeding grounds for dust mites, allergens, and bacteria that circulate in the air you breathe. A Hydronic Heating Cooling System harnesses natural temperature control methods which eliminates the potential of contaminated air.


A sustainable solution

Instead of using gas or coal-guzzling sources of electricity fuelling costly reverse-cycle systems, why not invest in a hydronic heating and cooling system? Our solutions are clean, efficient and can run on solar – the perfect addition to an all-electric home.


A smart, low-maintenance solution

G Store’s range of hydronic heating and cooling systems includes energy-efficient classic and cutting-edge European designs to suit both the contemporary and traditional home. We’re proud to offer the sleekest, most slimline and efficient technology to all our valued customers.


A cost-efficient solution

By using boilers, heat pumps, chillers, dry coolers and other super-efficient units, a Hydronic Heating Cooling System is estimated to be up to 35% more cost-effective than running an average ducted heating system. Choose hydronic and invest in the efficiency of your home.

To help you achieve all the benefits of G Store’s expertly designed hydronic heating and cooling systems, we offer:

G-Store are a really great bunch of people, friendly, helpful and super easy to deal with, the quote for my split system came quickly, the installation was arranged just... as quick and easy. Very respectful installers, took their boots off at the front door without being asked to, even though I said don't worry about it.. The after support when I couldn't get the wifi set up, priceless! Thanks guys keep up the great work. I would definitely purchase from G-Store again.read more

GStore and their contractors provide high quality products and installations. I had my solar battery installed in October 2023 and it works beautifully. I had already... had my solar panels installed by GStore in November 2019 and was happy to trust them again with this subsequent battery set-up. They did the installation with efficiency and professionalism. I also had an electric heat-pump hot water system installed by GStore in August 2023 and that transition from the gas HWS has also been seamless. Both installations have since been successfully audited for safety and installation compliance. I highly recommend GStore for their products and services.read more

Our second Tesla Powerwall was installed today and once again the whole process went very smoothly. We were not expecting it to be installed today but Melbourne’s... inclement weather meant the electricians couldn’t install solar panels so they installed our battery instead.Everyone involved from Greg at G-Store to electricians Ken, Luke and their co-workers were very professional.When we advised Greg we would like a second Powerwall, the quote came through the next morning.Very neat job again and we would have no problems recommending G-Store to anyone wanting energy efficient products.read more

Magnificent service! I was just beginning to explore solar, battery, aircon and hot water heat pumps when my current 28 yr old gas hot water system died. I asked if they... could do something within the next two or three weeks and the job was finished in two days. We are so pleased, smelling a lot sweeter and love the new Reclaim CO2 system. Thanks so much G-Store. More work coming your way.read more

We decided to add additional PV capacity to our existing system and the folk at G-store were very helpful explaining the options available. A detailed quote for our... selected option came the next day. I completed and returned the acceptance and was contacted to arrange an installation date on the same day. That was just two weeks ago. Our new system was installed on Monday by G-Store's nominated contractor who arrived on time, completed the job and left no trace - other than the new panels on the roof. Now waiting the Inspector to turn the new system on.A thoroughly professional and efficient provider.Thankyou to Greg McCann and his team of people.read more

My recent experience with G-Store Keysborough, specifically with Matt, was exceptional. Right from the start, they provided a fantastic price for the Powerwall... installation. Matt's communication was not only quick but also thorough, ensuring a smooth process from beginning to end.The installation itself was effortless, and the team left the area tidy and secure, even taking the extra step to lock the garage door after completing the job. G-Store Keysborough's commitment to great service, competitive pricing, and attention to detail makes them my top recommendation for anyone considering a Powerwall installation. Kudos to Matt and the entire team for their outstanding work!read more

Can recommend without hesitation. Alexey was great. Navigated the rebates for us and made sure the scheduling of the install met our specific needs. Long story but we... needed a 100% guaranteed install date weeks in advance and it was installed exactly as promised.Unfortunately not everything in life goes exactly to plan and we identified some minor issues post install. Stuff happens, but what can't be faulted was the prompt response by both Alexey and the installers to sort things out. Again, long story short, very happy with the outcome. The installers clearly take pride in their work which is shown by the neat install. See photos. Did I mention the Heat Pump is awesome?Thank you Alexey and team! 👍read more

We had solar panels installed many years ago and five years ago we installed more panels and a battery. We asked G-Store to remove and replace our old panels with new... ones. The operation was more complicated than it sounds, as we could not overload the existing inverter. G-Store found a very satisfactory solution, which involved the addition of a second inverter. The costs were carefully itemised and explained to us. Their installers did a marvellous job of installation, they were clean and tidy and thorough with the job. We highly recommend G-Store for quality advice, installation of solar panels and batteries.read more

I originally approached G-Store to talk about heat pump hot water, but after learning that the battery rebate was about to finish, I started looking into installing a... battery early (originally intended to do it next year). I spent several weeks studying the various options before working out what I wanted. I approached several suppliers, including G-Store (one of whom just stopped returning my calls and messages). Greg spent a lot of time explaining differences between the various systems I was looking at. The installation guys were also really professional and left the place clean and tidy. I knew Tesla had a good reputation, but I was a little sceptical at first, but those guys have done their homework. Having had it working for a few months, it works better than I had expected. My only surprise is that the Tesla Powerwall doesn't support 5GHz WiFi... no big deal.read more

My old electric water heater was bleeding me dry so I did quite a bit of research and found a heat pump would be a suitable replacement.I called around before... eventually going with G-star. From my 1st phone call Alexey was informative, honest and gave me the best quote by far for my reclaim heat pump.Lauren was attentive and made sure I was supported in applying for the rebates from start to finishDavid and co were on-time and professional and despite the rain, took the time to make sure the installation was perfect. Its been almost a month and I am seeing a HUGE drop in my electricity usage.Pump is near silent and hot water is plentiful and consistent. Extremely happy with our purchase! Thanks G-storeread more

He even provided information that other competitors had not mentioned which were very beneficial to us.read more
