Rointe understands comfort and brings it to your home

As the experts in thermal heating, Rointe introduce the new range of next generation home domestic heating: Delta Ultimate.

Enjoy a mild and pleasant heat, flooding every room in your home. A healthy heat, which keeps the humidity relative without drying out the environment using the natural convection of the specially designed fins.

With Delta Ultimate you can enjoy the warmest winter in your home with all the advantages offered by a low energy system that you can control from anywhere at any time. Sounds great right?

The new Rointe Delta Ultimate heating system will revolutionise the way in which up to now we understand the world of heating.

With a sleek new design available in two colours and latest generation electronics with built-in WiFi, the Delta Ultimate has been designed to bring you the comfort your family needs along with the most versatile control.

Savings with maximum efficiency

Delta Ultimate is not only a home heating automation system which provides maximum comfort to your home,the Delta Ultimate goes much further.

The most advanced heating system ever created by Rointe incorporates Fuzzy Logic Energy Control, the new low power technology developed by Rointe. Fuzzy Logic Energy Control has evolved from its predecessor Optimizer Energy Plus – with a faster and more effective start-up period allowing the initial heating phase to be stabilized, thus reducing the equivalent ratio of consumption to 38%.

But what does that mean? We know concepts such as 'equivalent consumption coefficient' sound complicated, so we will make them easy to understand.

During tests performed in independent laboratories under specified parameters, a Rointe radiator with Optimizer Energy plus patented technology heating a 12m2 room to a set temperature of 21ºC for a period of 24 hours only uses power for less than half of the time, in fact only 40% of the time. So, it only uses 40% of the nominal power that it has available.

In other words, to keep the room at 21ºC for 24 hours the radiator only has to work for 40% of the time, which we define as equivalent consumption coefficient.

According to tests conducted by Rointe on the Delta Ultimate range incorporating the Fuzzy Logic Energy Control, the consumption is reduced by a further 6% from the Optimizer Energy Plus – taking the equivalent consumption coefficient to 38%.

The range of Delta Ultimate radiators have been designed down to the smallest detail. With an innovative curved design and slim-line aluminium side locks, the back lit touch control panel, the new advanced Fuzzy Logic Energy Control and E-Life Technology technologies - all make the Delta Ultimate radiator the flagship of the brand.

Low Consumption

Thanks to its Fuzzy Logic Energy Control technology, the average power consumed by the Delta Ultimate radiators accounts for only 38% of its rated power.

Irregular product with side locks

New curved design with slim line aluminium side locks on both sides to give the product a compact finish and a consistent look.

Optimised design for maximum dissipation

Maximum performance thanks to the new design of the bar, fins and the 98 mm depth of each element, with room for 50% more thermal fluid than other products on the market.

SMD electronics and advanced technology

Multi-layer surface mounted electronics with dual micro-controllers Rointe XLP8 & XLP16 Extreme Low Power, long lasting lithium battery and Triac as cutting element.

Optimal trade off between w/item

110 watts per element provide balanced heat transfer compared to other radiators on the market that consume between 125 and 160 watts per element, making them less efficient.

E-Life technology

The E-Life Technology allows the heating to be managed from the Internet in a simple manner and with individual control for each radiator.​

TFT screen

1.77″ TFT Screen, the next generation, high contrast screen offers optimal viewing from any angle.

The first radiator in the world with WiFi Inside

The first WiFi inside radiator in the world with WiFi module to control its functions from a smart phone or tablet without intermediate terminals or other external elements.

Advanced control by touch panel

Total control from the radiator itself using the built in back lit control panel.

Available in two colours

Product range finished in a sleek graphite and white for seamless integration into any environment.

Quality Assurance

Total security with a 10 year warranty on the aluminium, and 2 years for electrical components.

When looking for a Wifi controlled system to replace my oil based heating system I researched to within an inch of my life. This is by far the best system I could find. its great as all you need is the radiator and the app on your phone. No nodules or any thermostats etc

I have started with one radiator but will work to one or more per room and replace my water heating system to Rointe too.

Yes its expensive, but when you add up a whole system and your savings it works good value.

Since installing the item (literally 3 holes and plugging it in) it has been awesome, our room has never been so snug and I love the fact I can use my app anywhere to adjust the temperature.
Thank you for your really great feedback of your new WiFi controlled Rointe Ultimate electric radiator, and please do not hesitate to contact us again if you require further Rointe Delta Ultimate electric radiators.
“Awesome Service”
I ordered at 2pm on a Tuesday and the radiator arrived at 10am the next day. I'm more than impressed. I ordered on the phone too and the assistant was wonderful.
Thank you very much for your fantastic review regarding our great service and your new Rointe Delta Ultimate white digital electric radiator. 

I will certainly  pass on your wonderful comments.

Happy with the product, and being able to control them via the internet was why i went for this range of radiators.

Product great although there looks to be some issues when using the phone app to control the heater, such as it wiping all of the timer programming for no reason that I could see. This happened twice so I now avoid using it so to ensure I don't have to reenter all of the program times
Thank you very much for your review of our service and the Rointe Delta. 
If you are having any problems with the app, please give Rointe a call directly on 01432 598019 and they should be able to resolve any issues. 
“Excellent service by Heater Shop”

Excellent web site, excellent sales support and delivery but when there was a problem, they really could not cope with it and it ended up my having to ddeal directly with the manufacturer to find a solution
Many thanks for your feedback.
When it comes to programming issues - it is generally more efficient to deal with our support partners / manufacturers, although we will of course be with you through the process, and until any issues are resolved.
