Frequently asked questions:

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 info@radiwarm.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.
