What Is Radiator Central Heating?

A boiler running on natural gas, diesel, LPG or an electric air-water heat pump heats water; this then circulates through a network of pipes to a series of radiator panels.

The hot water heats these radiator panels before returning to the boiler for reheating and re-circulating. The radiators heat quickly to provide radiated and convected heat. This results in a clean, silent, draught-free and comfortable whole house heating. In other words, it is ‘A Better Heating Solution’.

A fully programmable, thermostatically controlled Radiator Central Heating system allows you to heat the whole house or heat different rooms at different times of the day.

Healthier

Underfloor and central radiator heating are dust-free and allergen-free, making them ideal for medical conditions such as asthma.

Warmer

Radiator Central can warm up and cool down quickly, making it ideal for New Zealand’s seasonal temperatures. It heats a room by radiant and convection, creating a more comfortable temperature.

Cost Efficient

In a house with 2.7 m ceilings, a radiator heating system will cost around 20% less to operate than a ducted system. Homes with higher ceilings will see even more significant cost savings of 30-40%.

Renovate, New, Retrofit

Radiators are the most straightforward and least invasive to install when access is below the floor.

Stylish

Specific radiators will suit your taste, whether you have a classic villa, a modern masterpiece, or your first home. Underfloor heating systems also allow a minimalist design, providing heating that cannot be seen.

Controllable

An underfloor and radiator central heating system allows you to heat the whole house or different rooms to different temperatures at different times of the day.

frequently asked questions

FAQs

How does radiator central heating work?

Hydronic radiator based heating systems use a heat source such as a boiler or air-water heat pump.

Where are the radiators manufactured and from what material?

All of our radiators are designed and made in Europe by well known and respected suppliers. Depending on the style, our radiators are made from die-cast aluminium or steel and finished in a durable powder coat finish.

What size radiator should I use?

Our tech team will consider the size and volume of each space, along with the size of doors and windows to calculate the specific heat load (watts) required to maintain a comfortable temperature. This figure can then be cross referenced against a wide range of radiators to find an optimal size and shape that works in the room. A range of options might be possible so long as the output meets or exceeds the rooms requirement.

Can I combine my radiators and underfloor heating into a dual system?

Yes this can be done, but underfloor and radiator systems run at different temperatures so adds to the complexity and therefore the cost. 1 t is a nice option if you have a reasonable size ground floor with underfloor heating, and a second level with a timber floor construction which lends itself to radiators.

What heat source runs my radiator system?

Your radiator system is heated by your boiler or air-water heat pump, the energy source is decided by the cheapest available fuel in your region e.g. natural gas, LPG, air-water heatpump, diesel or wood. The choice of a wood burning boiler (wetback on a large wood fire), however requires effort on your part to keep the wood fire burning constantly.

How do I control the temperatures?

The heating system is primarily controlled by a master programmable thermostat which turns the system on and off according to your preferences. It is normally located for user convenience in the main living space.

A thermostatic head fitted to each radiator maintains the temperature of individual rooms independently from the master (subject to the master turning the system on). This is particularly useful if a room is unoccupied or disproportionately warmed by the sun.

Do you offer heating solutions for older homes?

Yes, we specialise in installing heating systems in older homes, ensuring minimal disruption and excellent results.

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.

Lorance

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.
