Ensuring a warm and safe home

Kelvin is backed by years of research and development. An essential part of the R&D process was ensuring Kelvin is certified to the EN 60335-2-30 and EN 60335-1 standards. These certifications ensure Kelvin meets the highest European safety standards. All models also have an IP44 rating allowing them to be used safely in bathrooms and kitchens, where resistance to water splashes and moisture is needed. Kelvin also complies with the more recent EU Lot 20 Legislation around heating efficiency.

Hot style

Excellent design. Love the way it works. A bit of a hassle to hook up due to it only working on 2.4ghz so I had to fiddle with the Wi-Fi router mesh set up to get it to work. And the invite a family member to have an account just doesn’t work. Shipping was excellent and hard to believe only $22 from the EU to California.

Kelvin heater

I have bought 2 Kelvin heaters for my living room and I’m really enjoyed the heat they deliver.
They look great in black and once connected to the WIFI the app is really easy to use.
The team from BOLDR has been extremely helpful first with the delivery from EUrope to the UK thanks to Brexit and after with the set up with 1 of the heater.
Finally Itbwould be better to have a more detailed notice how to set up the heater with the app and WIFI. Not everyone is an expert in smart home setting
Strongly recommend any way.
Thank you.

Best heaters I've come across, cannot recommend enough!!

I got both a large and small Kelvin for different sized rooms, and they are both *the best*!! They're truly silent as they're functioning, the app is easy to use and allows a wonderful amount of precision, setting what temperature I want, for which room, at what times of day, etc. They do a great job! Plus, they are amazingly good-lookin' – they go great with my general decor, and are more like pieces of art hanging on the wall instead of space heaters. As other reviews have mentioned, expect compliments. In the past I've gotten noisy little engines that are in-the-way, taking up precious floorspace, both with their machinery and also the ratty cords. No such issues with the Kelvins.

It's also worth mentioning I reached out to support with some questions regarding setup, and they were quick, patient, and very helpful. BOLDR is the real deal, I've been actively recommending them to friends and family knowing that they'll be well taken care of.

Get yourself a nice heater!! You deserve this quality and warmth in your life!
