Why the Nuuk Hot Blox OFR became my go-to heater this winter

It’s mid-January, and the winter season is still at its peak in the NCR region. I’ve been using the Nuuk Hot Blox oil-filled radiator (OFR) for a little over a month now, and what I initially thought would be just another OFR from an up-and-coming brand has turned out to be one of the most valued additions to my home this season. I’ve lived with enough blower heaters to know that most of them either heat the room too aggressively, dry out the air, or make so much noise that you can’t use them comfortably for long hours. That’s exactly why I generally prefer OFRs, and the Hot Blox fits right into that preference, while adding a modern twist. Let me explain.

First and foremost, from a health point of view, OFRs make far more sense than regular blowers. Unlike blower heaters, there’s no hot air being thrown directly at you, and instead, the heat from an OFR feels steady and gentle, which makes a big difference if you’re sitting in the same room for hours, sleeping at night, or even dealing with allergies. In fact, an OFR can be safely run throughout the night, which is something that can’t really be said for most blower heaters. That said, OFRs are also known for higher electricity consumption, especially if they’re run at full power all the time. This is where the Hot Blox tries to be a bit smarter.

In daily use, it works like a regular oil-filled radiator. You get three heating modes: 1000W, 1200W, and 2200W, along with auto cut-off and a stable heating output that gradually warms the room. But the real reason this heater stands out is what it does beyond the basics. The intelligent Eco mode automatically shifts between different power levels to maintain a set room temperature, instead of running at full blast unnecessarily. I personally use the heater on Eco mode for two main reasons: it lets me set a custom temperature, and once the room reaches that temperature, the heater autocuts to save electricity. Over time, this does help in keeping power consumption in check, even though this is still a high-power appliance.

Apart from this, the smart features on the Nuuk Hot Blox are something I didn’t think I’d care much about initially, but I’ve ended up using them quite a lot. The app lets me turn the heater on or off remotely, set timers, and adjust temperatures. This also means that around 20 minutes before I reach home, I can switch it on in advance, so I’m not stepping into a cold room. It feels oddly luxurious for a heater, but also genuinely useful.

What I appreciate even more is that Nuuk hasn’t made the heater app-dependent. It comes with a physical remote, which is a big deal at home. These days, not just the nights but even the afternoons are quite chilly. During the day, my parents use the Hot Blox in their room, and since they don’t have the app installed, the remote makes things simple. They can control the heater without getting up from the couch, which might sound like a small thing, but in everyday use, it really matters. There’s also a touch panel on the heater itself, so you’re covered in every situation.

Performance-wise, the Nuuk Hot Blox has been reliable. It heats the room evenly, operates with zero fan noise, and remains comfortable to use for long hours, including overnight. The build quality feels solid, and the metal body gives it a premium look that doesn’t scream ‘temporary winter appliance’ sitting in the corner of the room. Safety features like overheat protection and auto shut-off add peace of mind, especially when it’s running for extended periods.

If I had to nitpick, the price could have been tighter. The Hot Blox has dropped slightly from its initial asking price of about Rs 14,000 to roughly Rs 12,649 at the moment. Even so, a more aggressive price would have made it an instant recommendation for everyone. Established brands are already selling their 11-fin OFRs for close to Rs 10,000, which is something buyers may want to consider before locking in their purchase. That said, once you factor in the smart controls, the remote, the design, and the overall experience, Nuuk’s offering does justify itself better than most conventional OFRs.

Overall, I personally like the Nuuk Hot Blox because it feels like a modern take on a heater category that hasn’t changed much in years. It keeps the health benefits of oil-filled radiators intact, adds smart convenience where it actually helps, and delivers consistent performance during peak winter. For me, it’s been a dependable, comfortable, and genuinely useful addition to my home this season.
