About Viessmann Boilers
Viessmann is widely regarded as the premium choice among heating professionals. Founded in Germany in 1917, the family-owned company has built its reputation on engineering excellence, longevity, and industry-leading efficiency. Viessmann boilers are often the first choice for engineers who want to fit a boiler they'll be proud of — and that will serve their customers reliably for many years.
The Viessmann Vitodens range uses inox-radial stainless steel heat exchangers — a technology that significantly extends boiler life compared to aluminium alternatives. With efficiency ratings of up to 99% on modulating output, Vitodens boilers sit at the very top of the ErP efficiency scale.
RapidBoilers engineers have completed Viessmann manufacturer training and regularly install the full Vitodens range across Birmingham and the West Midlands. Our expertise means your installation is done right first time, and your warranty is fully protected.

What Makes Viessmann Different?
Several technical features set Viessmann apart from other boiler brands at the premium end of the market:
- Inox-Radial Stainless Steel Heat Exchanger: Resists corrosion and limescale better than aluminium, extending boiler life significantly — particularly important in Birmingham's moderately hard water area.
- Lambda Pro Control: Continuously monitors the fuel-to-air ratio and self-adjusts for maximum combustion efficiency, regardless of gas supply variations.
- MatriX-Plus Cylinder Burner: Viessmann's surface burner design achieves extremely low NOx emissions and ultra-quiet operation.
- Wide Modulation Range: Vitodens boilers modulate down to as little as 19% of their maximum output — far lower than most competitors — ensuring the boiler runs efficiently even in mild weather.
- ViCare Smart App: Full remote control, energy reporting, and service scheduling via Viessmann's intuitive smartphone app.

Viessmann Installation FAQs
For many homeowners, yes. Viessmann's inox-radial heat exchanger and wider modulation range typically result in lower running costs and longer boiler life compared to entry-level alternatives. The 10-year guarantee also reduces the risk of unexpected repair costs. The premium upfront cost is often recouped over the boiler's lifetime.
The Vitodens 100-W and 200-W achieve SEDBUK efficiency ratings of up to 94% at full load, and even higher at partial load due to the wide modulation range. This places them at the top of the ErP A rating band — meaning they're among the most efficient condensing boilers available.
Viessmann offers a standard 2-year warranty on all boilers, extendable to 5 or 10 years when installed by an approved installer and registered within 30 days of installation. The extended warranty covers both parts and labour and is backed by Viessmann's own UK service network.
Yes. All Vitodens boilers are compatible with the Viessmann ViCare app via the Vitoconnect module. The 200-W has smart connectivity built-in. Viessmann systems are also compatible with Nest, Hive, and Honeywell T6R thermostats if you prefer a third-party controller.
We typically have Vitodens boilers in stock or available for next-day delivery. Subject to survey, we can often complete your installation within 3–5 working days of your initial enquiry — or sooner if there's urgency.
