Viessmann boilers offer a range of advantages, but they also have some drawbacks like all other brands. We think that you should be aware of all the details before making a purchase.
Long lifespan: Viessmann boilers are built with high-quality components that contribute to their extended lifespan. This is further enhanced by the incorporation of quality parts like the Inox-Radial stainless steel heat exchanger, which promotes long-term efficiency.
Quiet operation: Viessmann boilers are quiet, ensuring a peaceful home environment.
High efficiency: Viessmann boilers are among the most efficient on the market, with many models operating at 98% efficiency. This translates into significant energy savings and lower heating costs.
Weather compensation: Viessmann boilers incorporate a range of smart heating features, including weather compensation. This system compares the outdoor temperature to the thermostat settings and adjusts the boiler’s operation accordingly, ensuring optimal heating efficiency and comfort.
Extended 10 or 12-year warranty: While a standard 5-year warranty is provided, Boilerhut can extend it to 10 years (on the 050 and 200 models) and 12 years (on the 100-W model) as we’re a Viessmann premium installer. This extended warranty provides peace of mind, knowing that your home heating system will receive the necessary care. As long as the manufacturer service plan is followed, the Viessmann boiler warranty covers individual parts within the boiler, such as the signature stainless steel heat exchanger.
Higher cost: Viessmann boilers can be more expensive than some competitors, such as Baxi and Vaillant. However, if you get a quote with Boilerhut you may be surprised. Often a premium Viessmann boiler and installation will be cheaper than our competitors.
Occasional system errors: Like other brands, Viessmann boilers are not immune to occasional errors and faults. The system does show error codes to assist in troubleshooting or informing your boiler engineer.
Overall, Viessmann boilers offer a combination of durability, efficiency, and innovative features that make them a compelling choice for homeowners seeking a high-performance heating system. However, it is worth noting that in a few circumstances they can be slightly more expensive than other brands.
