Air To Water Heat Pumps

Air-to-water heat pumps are among the most energy-efficient and eco-friendly ways to heat your central heating systems and domestic hot water production. They are the best option for new system installations and to replace aging gas boilers. Using the same fundamentals developed with traditional heat pumps, air-to-water heat pumps use reclaimed energy to salvage heat from the air, compress and transfer this to the water within the central heating system. This system reduces your carbon footprint and increases your central heating energy efficiency. Modern R290 Refrigerant high-temperature air-water heat pumps can heat water to 75 degrees Celsius, making them the perfect fit for replacing dated gas boilers.

Air-to-Water Heat Pumps: The Ultimate Energy-Efficient Solution

Upgrade your hot water system with our efficient central heating systems, designed to meet all your domestic hot water needs. We offer two main methods to achieve this: a combi-boiler or a hot water cylinder heated by the boiler, eliminating the need for electric elements.

Eco-Friendly and Efficient Heating

Air-to-water heat pumps are among the most energy-efficient and eco-friendly warm water central heating systems available. They are an excellent option for new installations or replacing ageing gas boilers. Their sustainable design makes them a standout choice for modern heating needs.

How Air-to-Water Heat Pumps Work

Using principles similar to traditional heat pumps, air-to-water heat pumps reclaim energy by extracting heat from the air. This heat is compressed and transferred to water within the central heating system. The process is highly efficient, reducing energy consumption and minimising your carbon footprint.

Advanced Technology and Efficiency

Modern R290 refrigerant high-temperature air-to-water heat pumps can heat water to 75 degrees Celsius, making them an ideal replacement for outdated gas boilers. These pumps generate up to four times more heat energy than the electrical energy they consume, offering: sustainable energy use, significant cost savings, reduced reliance on traditional fuels, lower carbon emissions

Versatility and Integration

Air-to-water heat pumps are highly adaptable, seamlessly integrating into both new constructions and existing heating systems. They provide reliable, efficient warmth for properties of all sizes, ensuring consistent comfort while contributing to a greener, more sustainable future.

What Our Clients Say

Wellington’s longest running and most trusted Radiator and Underfloor Central Heating company.

Flow designed and installed radiator central heating for us in June 2020. This was one of the best decisions we’ve made. We can now use every area of the house all throughout winter – not more spot heating and avoiding areas because it’s too cold. The radiators Flow recommends/supplies provides such a nice, clean heat, it doesn’t feel like you have a “heater” in every room. The radiators are sized perfectly for each room, with a range of sizes, and ability to individually change the heat output. The install team were particularly great. Whilst install was necessarily disruptive, the team made it as easy as possible with the needs of me and my newborn. 100% recommend.

Adele

Simon, Stevie and Miceal have being exceptional from day 1. When I decide to install radiators home I got several business to come over my place to give me their opinion on how install radiators in my 1900 old house. Only Flow crew was able to immediately come with a very clear plan and show great competence in the field. Really a great team work and exception competence. Stevie and Miceal have a quite extensive experience in heating systems and radiators which is quite hard to find here in town. I really appreciated the customer care from the quote throughout the installation process, and the ability to have always a positive approach toward any request or unexpected complexity coming from the layout of the house. Flow is definitively a must go if you are planning to install radiators in your home! Thanks guys! Maurizio

Maurizio

Simon and the team from Flow Plumbing and Heating recently installed a hydronic central heating system in to our home. Steve and Mason have done a great job, they were professional, respectful of our home and the work completed looks great. We would be more than happy to recommend Flow Plumbing and Heating to anyone.

Owen

Simon and Michael did an awesome job retrofitting/installing the radiator system in our home. They were patient with us and completed high quality work. They also went above and beyond to clean up after themselves each day, even when we were saying this wasn’t necessary. We had compared quotes from several companies and did plenty of research prior – Flow had the highest quality products, the best value for money, and then their service was impeccable. It was clear that they had a lot of respect for our home.

Chris and Michael from Flow Plumbing have just finished installing central heating, with 7 radiators in my house and small apartment downstairs. Having tradespeople in your home for an extended period of time, is sometimes very stressful, but having Michael and Chris here was very easy. They were very professional, tidy and went the extra mile, by pulling up floorboards to make the job was neat & tidy. Thanks to Simon for sending me the A team. Highly recommended.

Lee

I would definitely recommend Flow Plumbing to anyone considering central heating. The whole process has been smooth and very professionally managed with no problems at any stage. The installation was done without any mess in the house and the finished job looks very nice and works perfectly. The components (boiler, radiators etc) are all very good quality. I am very pleased that we finally got gas central heating installed – I only wish we had done it years ago! Will be using Flow again in the future if we ever move house, but for now we wil just enjoy our toasty warm house and endless hot water this winter! I just had the system serviced after a year – there were no problems and they adjusted it to make it work even better!

Paul

Flow replaced a central heating boiler installed by the previous owner of our place. Firstly they were able to provide a quote within a day or so by sending them pictures of the current setup. Then they were available quickly to install and do some repair work to pipes etc. All pretty easy, and Chris who did the installation was real helpful in general, and in getting the wifi and app sorted for boiler control. No surprises on how good Flow are given their 4.9 overall rating.

Lewis

We recently contacted the team at Flow Plumbing and Heating regarding installation of radiator central heating and an infinity hot water system. We were extremely impressed with the service provided. The team (Simon and Chris) were friendly and professional, they kept us fully informed throughout, and the entire installation process went smoothly. There were no hold ups with tradies or products. The installation guys (Chris and Holden) did a fantastic job, the radiators look fantastic, and our house is toasty warm. Huge thanks to the team at Flow. We love our new heaters, you did a fabulous job and it was a pleasure working with you. We wouldn’t hesitate to recommend the team at Flow.

Julie

Look no further. The team from Flow Plumbing are professional, respectful and did an outstanding job. Even my hard to please father, (old-school carpenter) was highly impressed with the work, finishing and conduct – high praise indeed. The radiators look great, and my house is consistently warm throughout with no nasty hot or cold spots. Well worth the investment – what are you waiting for?

Nicola

We had a full system of 11 radiators, heatpump, hotwater cylinder, thermostat/hub installed in our house by Flow Plumbing and Heating. The results have been transformational. The house is now warm & cosy in every room and the heat generated by the radiators is a lot more “warming” than the pitiful output from the previous two heatpumps. I honestly don’t know why radiators are not more common in NZ like they are in other parts of the world. I was hugely impressed by the workmanship of the installer (Peter) and his apprentice. He didn’t cut corners and took the time to get everything installed neatly and professionally. Great job and a very happy customer.
