Powerdown Energy Management

Intelligent electronics reduce the energy usage to the minimum required for your comfort. The heater and room thermostat work together using a combination of methods including chrono-proportional control to reduce the power input smoothly from 100% to 0%.

High Performance Heating Tablets

The unique solid core has been designed to maximise warmth. With high levels of aluminium oxide the tablets retain heat for long periods of time, which increases levels of radiant heat. Radiant heat works like the sun and keeps you warm at a lower air temperature.

Direct Acting Heating Elements

The heating elements are fully embedded in the bricks to reduce energy waste and maximise lifetime. It ensures super fast, highly efficient heat transfer directly to the solid core and reduces the risk of oxidisation (rust). Non embedded elements heat air before the core and are more likely to fail.

Natural Air Convection System

Precision engineered flutes are shaped to promote quick room heat up naturally. The flutes are 25.2mm deep and shaped to create a vortex as the air rises. This helps the room heat quickly without the cost or stuffiness of fan assistance.

Don’t take our word, see what our customers say about us.


After exploring various ways of reducing the carbon footprint and heating bills of our house - which happens to be an old 16th Century pub - I chose Sunflow because their radiators seemed to be the perfect way to achieve those reductions. One of the best decisions I have ever made. Through initial contact, surveying, quoting, planning, stripping out of our old radiators and pipework, to installing our neat, slimline radiators, Sunflow staff were unfailingly friendly, helpful and professional. We felt that they were all proud to work for Sunflow and that it really mattered to them that we should be satisfied customers.

Mrs. M. Pickford, Northamptonshire


I have been using Sunflow heaters for over 8 years now and have nothing but praise for them. They provide gentle background heat and can be programmed to maintain an ambient temperature to within half a degree of accuracy. I have a 1901 Bluthner grand piano in the music room, which has befitted greatly from a constant 24 hours a day low level heating and as a result has become so much easier to maintain and holds its pitch remarkably well now. Although the initial outlay was quite high, you can say in this case that, 'you get what you pay for' and really are worth every penny I invested in them. Sometimes I require a little assistance to reset the thermostat/ timer on the electronic one I have, but this is never a great problem as I can always ring the office and they're always patient and happy to give me clear guidance on how to reset. I can strongly recommend this type of heater to anyone and for me and my family it has proven to be a really sensible thing to invest in.

David Cooper


Dissatisfied with the six Dimplex sandstone brick night storage radiators in my 200-year old terraced cottage, I arranged a survey with Sunflow. The main issue was that Dimplex took such a long time to heat up, leading to the need for supplementary electrical heating. The visit from a very reassuring Sunflow Surveyor confirmed that a conversion to new radiators would deliver a more efficient heating system. I have since had six Sunflow radiators installed in my home, and moved from a night storage to a standard electricity tariff .I have been entirely satisfied – Sunflow radiators take just twenty minutes to produce optimum heat, provide lower power consumption, swifter heat production, and a much greater degree of heat control. From practical experience, I would recommend Sunflow radiators to anyone.
