The Bottom Line

Viessmann boilers are popular, and generally reliable, efficient, quiet, and designed for lasting performance. They don’t have a ton of novel features and technologies the way some competitors do, but that’s because they focus their attention on proprietary designs that increase the lifespan and performance of their boilers.

You can find affordable Viessmann boilers that are high-efficiency and backed by a decent warranty, so these systems are sound investments that will save you plenty on energy bills.

Real Viessmann Boiler Reviews

Real Canadian homeowners with Viessmann boilers say they’re quiet, reliable, and efficient. ENERGY STAR certified gas boilers use 10% less energy than standard boilers, and Viessmann boilers are ENERGY STAR certified. They run well and don’t experience too many maintenance issues, but it’s still important to have your boiler maintained annually. What’s more, people like that Viessmann has good customer service and tech support and that parts are readily available.

Viessmann Average Boiler Price Range

$5,000 – $8,000+ including installation

Without knowing all the specifics, you can’t get a really good idea of what it might cost to buy and install a new Viessmann boiler. So many things can affect the price, including:

• Boiler size and output
• Where you live
• Number of zones
• Special features and AFUE ratings
• The specific type and model you buy

For example, all Viessmann boilers are condensing boilers, and while this means they’ll be more efficient, it also means they’ll be more expensive.

Those are all things that will impact the cost of the boiler itself, but you also have to budget for installation, and this can range from $1,700 and $3,700 or more. The cost of installation depends largely on the same factors as above, such as where you live, the make/model/size of the boiler, and zones, as well as your home’s current plumbing infrastructure.

Finally, check for rebates any time you’re looking to buy HVAC equipment. Rebates might be available through a local HVAC distributor, your energy company, the government, or the manufacturer.

Viessmann Condensing Boilers

Viessmann has two high-efficiency condensing gas boilers in their product lineup, the Vitodens 100-W B1HE and Vitodens 200-W. They are both similar models, and boast a 95 percent AFUE rating, ENERGY STAR certification, and ENERGY STAR Most Efficient of 2020.

These boiler models are equipped with Viessmann’s proprietary MatriX cylinder burner and Inox-Radial heat exchanger, both of which promise lasting and efficient performance.

Between the two models, there’s a heating output ranging from 21,000 to 530,000 BTUs, so there’s a boiler size that can accommodate just about any space. These wall-hung models also have a compact and easy-to-install design, making them ideal for all sorts of homes and space designs.

Viessmann Condensing Combi Boilers

Viessmann’s condensing combi boilers take all the technologies and benefits of their condensing boilers and pair them with water heating capabilities, so one unit can heat your home and generate all the hot water you need for cooking, cleaning, and bathing.

There are three models to choose from in this category, the Vitodens 100-W B1KE, Vitodens 222-F, and Vitocrossal 300, with one model having an efficiency rating of 98 percent. There are both wall-hung and floor-standing models available.

The boilers in this category have all the same great design features as Viessmann’s regular condensing boilers, as well as having low emissions and easy-to-operate controls, and some are equipped with the Lambda Pro gas management system.

Viessmann Exclusive Features

Feature 1 – Inox-Radial and Inox-Crossal Stainless Steel Heat Exchangers

No Viessmann boiler review would be complete without an examination of the brand’s special features, which includes their proprietary heat exchanger.

Depending on the model, a Viessmann boiler will come with either an Inox-Radial or Inox-Crossal stainless steel heat exchanger. They are designed with smooth stainless steel heating surfaces that allow for easy condensate drainage, producing a self-cleaning effect that makes for a reliable and long-lasting heat exchanger.

These heat exchangers are also designed for improved heat transfer and corrosion-resistance, plus they’re backed by a great warranty, so they’re guaranteed to provide efficient and ongoing operation.

Feature 2 – MatriX-Plus Burner

MatriX-Plus is Viessmann’s unique cylinder burner design that promises excellent efficiency, quiet operation, and low nitrogen oxide emissions. The burner is also resistant to high temperatures, meaning it’s more reliable and longer-lasting than regular burners. The MatriX-Plus comes standard with every Viessmann boiler, so you know all their systems are dependable and durable.

Feature 3 – Vitotronic 200 HO1B Control

All Viessmann’s 200 and 300 series boilers come with the Vitotronic 200 HO1B control, an advanced control system that you can use to manage your heat settings, monitor the system, maximize your comfort levels, and keep an eye on efficiency and performance.  

The touchscreen display is easy to use, and it even allows you to do important things like service scans. Further, you can use the display to see fault codes to help you troubleshoot potential problems.  

Feature 4 – Lambda Pro Technology

Lambda Pro technology is a proprietary gas management system that enables the boiler to self-adjust to different gas types. What this means for your home is that your Viessmann boiler will always operate efficiently and optimally, no matter what type or quality of gas is being supplied.

The Lambda Pro technology also promises quiet operation, easy startup, and easier installation.

Feature 5 – ViCare

ViCare is an app you can download on a smartphone or tablet to control your boiler system remotely. App features include hot water scheduling, temperature control, fuel use reports, and more.

Viessmann’s Boiler Warranty

The warranty that comes with your boiler might not seem like the most important thing, but it is something you should pay attention to. For one thing, a good warranty could potentially save you hundreds or even thousands of dollars in repair costs throughout the warranty period.

Just as importantly, a good warranty means that the manufacturer stands behind their product for at least the length of the coverage period, so warranty terms can indicate the quality and reliability of the boiler.

Viessmann backs up all of their boiler models with the same decent warranty, which includes:

•  A two-year parts or standard equipment warranty for components like the burner, controls, and boiler enclosure
• A 10-year warranty for the pressure vessel
• A prorated limited lifetime warranty for the pressure vessel beyond year 10
