Standard Hydronic Radiators

Nissl Eichert’s standard radiators are the DeLonghi Radel steel radiator range. As the most supported range of panels in Australia, there are no problems in sourcing these radiators from the distributor as they are always in stock.

Made in Italy from the highest quality steel and available in a variety of sizes, these radiator systems will perfectly suit your home.

Designer Hydronic Radiators

If you are looking for a more modern option, then designer hydronic radiators provide a diverse range of stylish and contemporary looks. These can be further customised with a rage of finishes and colours allowing for even more individuality. There are also options for more contemporary valves to compliment your designer radiators.

Please note: Designer panels are custom orders and can take between 14 – 20 weeks to arrive.

Testimonials

Lainie Martino

We absolutely love our heating & hot water system recently installed! These guys were very helpful and knowledgeable and delivered exactly what was quoted and were always easy to deal with, helpful and accomodating. We have slab heating and hydronic panels coupled with combo boiler and it’s working perfectly for our family of four- highly recommended

Rod Ashcroft

The Buderus panels look good and blend nicely into the Victorian house… We are well pleased with the final result and can’t recommend Nissl Eichert highly enough.

Lisa T

Jake and the team at Nissl Eichert have been amazing to deal with. Their quote was very competitive and where other contractors were hesitant about things like under floor access and panel sizes for large rooms, Jake didn’t even bat an eyelid. The installers arrived punctually each day, were polite, hard-working and tidied up after themselves. Highly recommended.

Jerome Walsh

Wife discovered Nissl and they arrived at our house within 3.0 hours – brilliant! … Nissl quoted on a couple of units and were able to install a new boiler within 72 hours. Jamie (Tradesman – installer) was highly courteous and professional. Could not have been happier and will only use Nissl team to service boiler and panel units going forward. Sincere thanks to highly professional, no fuss, Nissl team!

Frequently Asked Questions

How Long Do Hydronic Radiators Last?

DeLonghi Radel panels come with a 30-year warranty* and towel rails come with a 10-year warranty*.

* Radiators installed in wet areas (like bathrooms) only come with a 12-month warranty due to condensation and corrosion. We recommend using a towel rail in these areas as they are designed to handle moisture.

Please note: These warranties do not cover the valves on the radiators or towel rails, which may need replacement as part of general maintenance.

Where Can You Place Hydronic Radiator Systems?

Radiators are best placed underneath windows because radiant heat moves from the wall into the centre of the room, and convection creates a warm air barrier at the glass. This reduces heat loss and prevents cold air from entering.

Most people don’t put large furniture in front of windows, so this placement also allows heat to circulate properly and blend visually with the window area.

If under-window placement isn’t suitable, we can adjust the design to your requirements.

Can You Put Furniture Against Hydronic Heating?

Hydronic heating works best when heat can circulate freely. Large furniture in front of a radiator reduces efficiency.

If placing a couch in front of a radiator, choose one with legs so air can circulate underneath, and position it as far away as practical. Leather will dry out over time, so regular treatment is recommended.

A minimum clearance of 100mm is recommended. Avoid hanging artwork or electronics directly above radiator panels due to rising warm air.

Does Hydronic Heating Use a Lot of Water?

Hydronic systems are closed loop—after the initial fill, the same water circulates continuously.

A bacterial inhibitor is added at setup and remains effective for 5–10 years. We check the water condition during the annual service and top up the pressure if needed.

The system only loses a small amount of water over time due to natural evaporation.
