View our frequently asked questions about the RadiWarm® and RadiWarm® Economy+
We’ve been making our Pipeless Radiators to the highest standards for many years, and here are some of the questions we get asked most often. If you still have a question call us on 01422 231943, email email@example.com, or use the form at the bottom of the page.
The RadiWarm is 100% efficient so all the electrical energy that goes into it is converted to heat, making it one of the most efficient heating solutions on the market.
The costs of running any heating system vary significantly based on how well your property is insulated, your electricity tariff and many different factors. However, on average the RadiWarm will heat up a 10m² room from ambient in about 15 minutes, using its self-contained patented boiler system to heat the water inside. 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 approximately 50% of the time it is active.
Our Pipeless Radiators are water-filled and heat your home just like a conventional plumbed central heating system.
Radiators arrive ready to use, filled with specially treated water and fully sealed. They don’t require plumbing, flushing, bleeding or topping-up before, during or after installation.
This ensures that the built-in patented boiler gives the same heat quality of a gas central heating system, but without plumbing, pipe work or even a gas supply.
A Pipeless Radiator can be used anywhere that has a mains electricity supply. This makes it perfect for use throughout your property, including loft conversions, gardens rooms, living rooms, kitchens, bedrooms, offices, garages and even bathrooms (our radiators are IP44 rated enabling them to be used in bathroom applications provided they are installed in the correct zone – IP44 is applicable to Zone 2).
If you’re looking to heat a conservatory, then there really isn’t a better option and we produce a special half-height version of the RadiWarm specifically for this use.
Many people also use a RadiWarm Pipeless Radiator to heat rooms that are on the ‘end’ of the heating system or may only require additional heat at certain times of the year.
Water-filled radiators heat up quickly and are more controllable than oil-filled versions.
Oil hits a peak then drops rapidly again needing a lot of energy to reheat. Once a RadiWarm reaches the required room temperature, the Smart Heating software puts the radiator into eco-saving mode, only turning the in-built boiler on when it needs to top up the ambient temperature.
Breathing dry air caused by typical electric heating systems can aggravate respiratory problems such as asthma and sinusitis.
Our unique water-filled Pipeless Radiators provide both convection and radiant heat – which doesn’t dry out the air and provides the same good quality heat as a typical plumbed radiator system.
On average the RadiWarm is also far more energy efficient than other heating systems.

None. Our Pipeless Radiators are fully sealed and filled with specially treated water. The radiator doesn’t require plumbing, flushing, bleeding or topping-up.
Our radiators are very quiet. Initially, there may be a slight gurgle when the radiator is installed until the air settles and you may hear a quiet hum when the pump is working, but outside of that they are virtually silent.
Our radiators are IP44 rated enabling them to be used in bathroom applications, provided they are installed in the correct zone. IP44 is applicable to Zone 2.
Pipeless Radiators are available in 11 different widths and 3 different heights to give you the perfect sized Pipeless Radiator for your property (including our low-height models perfect for conservatories). Use our guide during checkout to buy the right sized RadiWarm for your room or view our size guide here.
Yes, our water-filled radiators work best using Economy 10 or standard tariff, but your energy supplier will be able to help further.
We are proud to make all our RadiWarm Pipeless Radiators by hand in our modern purpose-built manufacturing facility nestled in the hills and valleys of Halifax, West Yorkshire.
Halifax has a strong industrial heritage that we are very proud to continue.
All our Pipeless Radiators are made in white to match the look of a traditional radiator.
All our Pipeless Radiators come with a 2 year guarantee as standard. Make sure that you complete your registration card online after installation.
In the very unlikely event that you have any problems with the radiator, then contact our office. We will ask you a couple of trouble shooting questions that normally fix 90% of problems. If we can’t resolve the issue over the phone, and your radiator is still under warranty, then we will send you a replacement.
The RadiWarm Safe Touch is the same pipeless radiator but includes a protective low-temperature cover.
From 1st January 2018, all local space heaters manufactured for sale in the EU which use electricity, gas or liquid fuels must comply with a minimum efficiency standard. The aim of this legislation is to remove inefficient technologies and reduce the energy used by the products that heat our homes, helping to achieve our overall carbon reduction targets. See website for more information https://www.lot20.co.uk/about
Every property is different so the running cost can vary due to a number of factors such as insulation level in the property, current electricity tariff, geographical area, and how the radiators are controlled etc. The radiator is designed to cycle so may only be using electricity for as little as 20% of the time.
Our unique silica sand Thermal Mass Radiators offer a convection and radiant heat, whereas other heaters use convection heating which gives off a dry heat.
Our radiator uses silica sand Thermal Mass cartridges which produces heat when warmed with an element.
Every room is different, we can make heat loss calculations and advise which radiator is suitable for the room, or use the size guide on our website.
Of course, our radiators are light weight! Full instructions are supplied with each radiator. All you need is a spirit level, pencil, drill bit and drill – fix the brackets to the wall with the fixings supplied, hang the radiator on the brackets according to the instructions, then plug in to a near by socket.
Yes, our radiators work best using Economy 10 or standard tariff but your energy supplier will be able to help further. Our radiator is much more efficient than storage heaters.
In the very unlikely event that you have any problems with the radiator, then contact our office. We will ask you a couple of troubleshooting questions. If we can’t resolve the issue over the phone, and your radiator is still under warranty, then we will send you a replacement which can be plugged in straight away.
Our radiators aren’t IP rated, therefore they are not allowed in any zoned area where there is a direct water source.
Initially there may be a slight noise. Thereafter the radiator should be silent.
As our radiators give a convected and radiant heat, the air quality is maintained and not dry like other heater types, resulting in a better, healthier environment.
Our radiators are maintenance free. The radiators are supplied as a fully sealed unit – just mount, plug in to an electrical point and they heat up within minutes.
We do not offer an installation service for our Economy+ models, but our radiators are easy to mount to a wall. Full instructions and brackets are supplied with each radiator.
They are hand built in the UK. Our factory is in Halifax, West Yorkshire.
The Economy+ is currently only available in white.
Loft conversions, garden rooms, living rooms, offices, bedrooms, garages – in fact anywhere you need.
Our radiators are currently available in 2 different heights and 6 different widths, all dependent on your heat requirements.
We don’t currently offer solar or battery power but we are looking at developing this in the future.
It’s just a matter of fixing the brackets to the wall and mounting the radiator, so it could be up and running in as little as 15 minutes.
No, the Economy+ model is controlled via the inbuilt control panel.
2 years on the electrics/electronic components.

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.
RadiWarm Pipeless Radiators saved our tenant over £350 in heating costs last year.
I am delighted because whilst the radiators are a huge improvement on my old storage heaters, they also comply with my own environmental beliefs.
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.
With over 20 years in the industry, the RadiWarm is the best heating system we have come across.
Your customer service and communication levels certainly exceed any company I have ever dealt with. Once again, thank you.
The Pipeless Radiators arrived yesterday afternoon. All four have been installed and are working well. We are exceptionally pleased that we have chosen RadiWarm.
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.
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.
