First Impressions of Viessmann 7855596 Radial Fan Nrg118 For Vitodens 100 W B1Ha/B1Ka 26/35 Series Boilers

As an experienced outdoor and tactical gear specialist, the realm of home heating might seem a far cry from my usual domain. However, the principles of reliability, durability, and efficient performance are universal, whether you’re talking about a dependable knife or a dependable boiler component. The Viessmann 7855596 Radial Fan Nrg118 For Vitodens 100 W B1Ha/B1Ka 26/35 Series Boilers promises to deliver exactly that, and I was eager to see if it lived up to the brand’s reputation.

My old boiler’s fan had been making a racket for months, a high-pitched whine that drove me (and the dog) crazy. I was desperately seeking a solution that would restore peace to my home and, more importantly, ensure reliable heating through the harsh winter months. The claim that this Viessmann fan offers optimal air movement and noise reduction immediately caught my attention.

The unit arrived well-packaged, which is always a good sign, suggesting the Viessmann takes care in how their products are presented. Upon opening, the fan looked robust and well-constructed, definitely not a flimsy piece of kit. The two-bladed V-Fan design was visually distinct, hinting at the promised efficiency.

I considered a generic replacement fan, which was significantly cheaper, but I’ve learned the hard way that cutting corners often leads to more problems down the line. I also briefly looked at a competing fan from another well-known boiler manufacturer, but Viessmann’s reputation for quality and the specific compatibility with my boiler model ultimately swayed my decision. Initially, I was cautiously optimistic. The price felt a bit steep, but the potential for a quiet, efficient, and long-lasting solution made it seem worthwhile.

First Use Experience

My “testing ground” was my own home, specifically, the boiler room (a converted storage space in the basement). The installation process, thankfully, was straightforward thanks to the Viessmann fan being a direct replacement part for my existing boiler. I carefully followed the instructions (and a YouTube video for extra assurance) and had the new fan installed within an hour. The initial start-up was the moment of truth.

The difference was immediately noticeable; the high-pitched whine was gone, replaced by a much quieter, almost imperceptible hum. The boiler fired up smoothly, and the house began to warm up quickly. There were no unexpected error codes or issues, which was a huge relief.

The fan continues to operate quietly and efficiently. I’ve noticed a slight improvement in the boiler’s overall efficiency, which, while hard to quantify precisely, translates to a small but noticeable reduction in my energy bills.

There are no signs of wear and tear, and the fan still looks and performs like new. Cleaning and maintenance have been minimal; a quick visual inspection every few weeks is all it takes. Compared to my previous fan, which was a constant source of noise and anxiety, the Viessmann is a dream. It has far surpassed my initial expectations.
