Boldr Reviews 129

Absolutely love this product! What a great way to heat a room. What a great alternative to an electric space heater. Ordered for my apartment because the heating system is older and my apt is so smal... See more

Our Kelvin is an Excellent Heating Source We have been using our Kelvin in the Master Bath for nearly 2 years. It provides an excellent source of radiated heat in the room for when we wake up, as w... See more

The back of our house has been cold every winter. These heaters placed strategically have definitely helped keep this area warmer and more comfortable. The forced air heat seems to be coming on a bit... See more

As a mom and homeowner, the Boldr Klima Smart Thermostat has been amazing for our family. It not only lets me monitor energy use and AC performance, it lets me set smart automations, create comfort z... See more

I echo all these other 1-star reviews. The app is complete trash that fails to connect to either version 1 or 2 Kelvin Heaters. It cannot connect directly or through the Klima thermostat. Support does... See more

The kelvin heater requires app access to turn on which is super frustrating when the app never connects to my wifi. After 1 year it's only connected to the app once which means that I've only used the... See more

Terrible device (Kelvin Heater) because the app is never pairing with device despite all manner of resets and restarts. Without the app to control the device I have just an expensive glass frame on... See more

What a letdown. The product is a waste of time and money. Support is entirely offshore, slow to respond, and only available when most people are at work. And if, after wasting your time and after... See more

Incredibly bad experience with Boldr. If you’re on a mobile phone you’ll note that the product page for the Kelvin has a "30 Day Money Back Guarantee” icon present. Great, right? Then I went to the... See more

I bought this heater from boldr with expectations it would help heat my sunroom. I tested it for 48 hours straight at 80 degrees it did not make much of a difference. When I contacted the company to... See more

Perspective from a HVAC tech. Although I’m typically skeptical of recommending new products to my customers, I’ve used this in my own home to control our sunroom Mitsubishi mini split which is 15 yea... See more

Had a small hiccup with installation and honestly thought I’d be stuck on hold forever. Their support team was the total opposite: answered in seconds, super friendly, asked for a couple pics, and wal... See more

I've had a great experience with Boldr. I was a bit hesitant at first when reading some of the reviews here, although so far so good! The customer support team has been quick to answer any questions I... See more

Good supplemental heat I have had less expensive panels in the past. Worked fine, but much less attractive than the Kelvins I recently purchased. These are heavy, so support them well when hanging. B... See more

The Boldr Smart Thermostat has been fantastic. It performs reliably, helps me easily track my AC performance, and the automations mean I always come home to a perfectly pre-heated or cooled house. On... See more

The product is nicer than I expected - it heats up quickly and provided a gentle warmth in a small bathroom with a poorly insulated external wall. Delivery was slightly delayed but customer servi... See more

We have a total of four Boldr Kelvin’s and they work great and would highly recommend them. And their customer support ( Zach) was very responsive when we had a couple of shipping hiccups So overal... See more

Bring the heat We were thrilled to install the BOLDR Kelvin Infrared Heater......... the wifi connect was very challenging and would have appreciated more detailed directions, however, we did connect... See more

I’m very happy with our Boldr Kelvin units. The infrared heating and schedule features have reduced our energy bills drastically. The infrared smart heater is easy to set up and lets you create your o... See more

Really liking Kelvin so far. The app gives you enough data to feel smart 😅 but it’s not overwhelming. I can see when the heating is actually running, adjust per room, and turn everything down when we... See more

This is a review for the Klima and the Boldr app that goes with it. I use it with a Tosot minisplit. I wanted to love this product. And I tried very very hard, until I gave up: - Google Home i... See more

The heater is attractive and I did not have any issues setting up the technology/connecting to the app. It does not adequately heat the space that I got it for and the app is trash. In retrospect,... See more

Overall very pleased with the ease of installation and setup process. The unit has really taken the bite out of a drafty bathroom following a major remodel. The sleek style doesn’t look out of place.... See more

After having an issue with one of our heaters, we were shipped a brand new one! The help desk is responsive and prompt in their assistance. Thank you for your care and prompt replies to our inquiries!... See more

I am thrilled with this product! It is everything it was advertised to be. Such even heat in my bedroom and I love all the smart functionality. I just ordered another one for my other bedroom!

The Boldr space heater was packaged very well and arrived in good condition . It was easy to set up, and works as advertised. I would purchase one again.

When I first saw the large Kelvin I knew it was just what I wanted and needed. I didn’t think wrong. My Kelvin is perfect. My new home is unique and different with an open concept. Lots and lots of wi... See more

We have a small guest room in our house that had no vent. It's always been cold. The small size Kelvin heater is able to warm it well beyond our expectations. It can make it hot on a cold day. 10/10

In my 115-year-old home, the master bath is not insulated. The pipes freeze in the winter, and so do I. Well, not anymore. Kelvin fits perfectly and works like a charm.

Great products, works very well with Hitachi aircon.

Quick and proactive support!

Very responsive customer service.

My small bathroom had no heat. The steady temp. ranged from 58 to 61 degrees, and it was like showering in an igloo. Because I didn’t want an electrical cord draped around the room, I installed a GFC... See more
