Boiler systems servicing

Regular servicing of the boiler that supports your heating system will lower your running costs. Maintenance involves stripping the boiler apart, cleaning the internal components and checking it is operating correctly and safely.

Boiler replacements

A well-maintained boiler will last 15 to 20 years, depending on the product quality. We replace existing boilers or those that are deemed to be close to the end of their life.

Flushing of heat systems

Power flushing of central heating systems is required approximately every six years to ensure they are running efficiently. This involves cleaning of the heat source , and clearing sludge or rust build up in the central heating radiators and pipework that we install. Regular maintenance keeps your heating product running at optimum throughout your home, prevents untimely breakdowns and ensures your product will last.

This helps lower running costs and extends the boiler & systems lifespan.

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.
