RadiWarm® arrives ready for use, filled with specially treated water and fully sealed. They don’t require plumbing, flushing, bleeding or topping-up. This ensures that the patented built-in boiler gives the same heat quality of a gas central heating system, but without the plumbing, pipe work or even a gas supply. Simply wall-mount the radiator onto special safety brackets, plug it into a standard British electrical socket and switch on. It’s as easy as that!

What our customers say


Pipeless Radiators have been a godsend for us. They are efficient, they heat up quickly and quietly, and they were very quick and easy to install.
Mr J Bett

RadiWarm Pipeless Radiators saved our tenant over £350 in heating costs last year.
Mr C Davis

I am delighted because whilst the radiators are a huge improvement on my old storage heaters, they also comply with my own environmental beliefs.
Mr J Ramsdale

Installing Pipeless Radiators throughout our home halved the cost of replacing our oil-fired system. Once they were all mounted on the wall all I had to do was plug them in.
Ms S Wilcox

With over 20 years in the industry, the RadiWarm is the best heating system we have come across.
Mr B West

Your customer service and communication levels certainly exceed any company I have ever dealt with. Once again, thank you.
Mr A O'Donell

The Pipeless Radiators arrived yesterday afternoon. All four have been installed and are working well. We are exceptionally pleased that we have chosen RadiWarm.
Mrs M Gardiner

I would just like to say thank you for your company's very quick delivery of my mother's RadiWarm. Very impressed! It’s up and running now. Thanks again.
Miss E Cameron

I have never before come across a system that looks and performs like central heating and offers excellent conversion of input to output of energy.

A real water-filled radiator, without the pipes

RadiWarm Pipeless Radiators® combine the heat quality of gas central heating systems with the simplicity of electric heating. Each water-filled radiator looks like a conventional radiator but hides an internal energy-efficient boiler and pump, transforming it into a self-contained heating system.

100% efficient

The RadiWarm® has 100% efficiency.  Once a room reaches the desired temperature, the RadiWarm’s Smart Heating software will switch to eco-saving mode to maintain ambient room temperature – only needing to pull electricity when required.

Installation service and free mainland UK delivery

The RadiWarm® is a true plug and play radiator.  Mount it to your wall, plug it into a nearby standard mains electricity socket and enjoy the heat of a real water-filled radiator.  Or take advantage of our installation service where we will install the RadiWarm® for you.

Meet the brains behind the RadiWarm®!

The RadiWarm Pipeless Radiator® is controlled by a 7-day programmable controller. One unit can control several radiators although we recommend different controllers for different zones (eg upstairs / downstairs).

We will automatically add a single controller to your order.  If you already own a controller from a previous order then you can remove it at checkout, or you can add extra controllers to your basket from our controller page.

You can also upgrade to our Smart Controller so that you can control your heating over the Internet from anywhere in the world.  Learn more here.

What size radiator do I need?

What size RadiWarm Pipeless Radiator® you need depends on many variables, including wall construction and what type of insulation you have.  Sometimes though, how much wall space you have and the availability of sockets are a bigger factor!

The below guides show the recommended radiator size based on an average UK home with double-glazing.  However, you can buy larger or smaller radiators to fit the space you have – if you buy smaller the space will take longer to heat up.
