Viessmann Boiler Features

Here’s a general overview of the features you’ll find across Viessmann boilers:

• Energy Efficiency: All Viessmann boilers are designed with high efficiency in mind. Most models achieve an A-rating for energy efficiency, with some reaching up to 98% efficiency. 
• Compact Design: Viessmann boilers are known for their space-saving designs. This is especially true for their combi boilers, which don’t require separate water tanks.
• Inox-Radial Heat Exchanger: This is a standout feature in many Viessmann boilers. It’s made of stainless steel, which helps prevent corrosion and increases durability.
• Smart Controls: Many Viessmann boilers are compatible with smart controls like the Vitoconnect, allowing for remote operation via smartphone apps.
• Modulating Burners: These adjust the flame to match your heating needs, improving efficiency and reducing wear and tear.
• Quiet Operation: Viessmann boilers are designed to operate quietly, which is a plus for homes where the boiler is installed in living areas.

Viessmann Boiler Warranties

All Viessmann boilers come with a standard 2-year manufacturer’s warranty. Many models, including the popular Vitodens series, are eligible for an extended 7-year parts and labour warranty when registered within 30 days of installation. Some boilers even offer the option to extend the warranty up to 10 and even 12 years for an additional fee.

These Viessmann boiler warranty options apply if you buy your boiler directly from Viessmann. If you purchase your boiler from Boiler Central, you can get an extended warranty, as well as a boiler cover for extra protection and peace of mind.

Viessmann Combi Boiler Range

Viessmann offers three main types of boilers: combi, system, and conventional (heat-only). Each type is designed to meet different household needs and heating requirements.

• Combi boilers provide both heating and hot water directly from the boiler without the need for separate water tanks. They’re perfect for smaller homes with limited space and moderate hot water demand.
• System boilers work with a separate hot water cylinder. They can provide hot water to multiple taps simultaneously without a drop in pressure, making them ideal for larger homes with multiple bathrooms and bedrooms.
• Conventional boilers are designed for homes with traditional heating systems. They require both a hot water cylinder and a cold water tank, and are able to meet high hot water demands in larger homes.

Common Viessmann Boiler Problems and Errors

Even high-quality boilers break down occasionally, and Viessmann boilers are no exception despite their reliability.

When something goes wrong, your Viessmann boiler should show an error code, which you can use to identify the issue.

One of the most common errors with any boiler is low pressure. Thankfully, you can repressurise your Viessmann boiler yourself and fix this issue.

There are a few other common issues that you can handle on your own, but if you’re unsure about the error or just want an expert opinion, then you should contact your boiler engineer.

If the boiler is under warranty and the issue is covered, you could get it fixed for free. However, if the issue is not covered, you’ll need to pay for it yourself.

While standard home insurance policies usually don’t cover boilers, it’s worth checking with your insurance provider to see what’s included in your policy.

If your boiler isn’t covered, repair bills can be quite expensive, especially if your unit needs new parts. That’s why here at Boiler Central we offer boiler cover. Depending on the plan you choose, you could save on everything from call-out fees to boiler replacement.

For some of our policies, we also offer free boiler servicing. A Viessmann boiler should be serviced every year, so getting this service for free as part of your cover can save you money and help keep your boiler running smoothly for longer.

How Does Viessmann Shape Up Against the Competition?

This article covers Viessmann boilers, but they’re not the only brand on the market. 

Boilers are an integral part of your home. They’re also an expensive investment that can last up to 15 years.

So, you need to do your research before you buy one. That means checking out all of the boiler brands out there.

As this article shows, Viessmann is a reliable boiler brand. However, if you want to make an informed choice, you should consider every option.

That means comparing Viessmann’s offering to the competition. Below is an overview of how Viessmann compares to some of the biggest boiler brands in the UK today.

Viessmann vs Vaillant Boilers

Both of these German brands have gained international reputations for excellence in boiler design and creation.

Viessmann boilers are often slightly cheaper than Vaillant models and slightly more energy-efficient. They also typically have better warranty options for both boilers and their components.

Vaillant boilers also have many positive points. Their boilers rate a little higher on Trustpilot and come with a somewhat more user-friendly control app.

Each of these boiler brands has pros and cons, so check out specific models to find your ideal solution.

Check out our overview of Viessmann vs Vaillant boilers to find the best boiler brand for you.

Viessmann vs Worcester Bosch Boilers

Worcester Bosch is a respected UK boiler brand. Established in 1962, the brand has been perfecting its boiler and heating system products ever since. As such, it’s a newer entrant to the boiler market than Viessmann, which has been creating quality boiler products for more than 100 years. 

Still, Worcester has gotten a reputation for reliability and innovation. Its products have a 4.6-star rating on Trustpilot, which is just slightly higher than Viessmann’s 4.5-star rating.

We compared the two best-selling boilers from each brand on our Worcester 4000 vs Viessmann Vitodens 050-w comparison page.

Both brands offer combi boilers, system boilers, and regular boilers. They also provide a selection of accessories and heating system solutions.

Worcester Bosch also offers more cutting-edge heating solutions. These include smart thermostats and digital controls. Many of its renowned Greenstar and Lifestyle ranges are controlled by the Bosch EasyControl app.

Worcester Bosch offers a 12-year warranty with most of its boilers. Viessman’s extended warranty is usually 10 years, although it does offer a 12-year option for some of its boilers. As such, both offer similar warranty options.

All of this could be the reason behind Worcester Bosch’s higher prices. The brand’s average prices are higher than Viessman’s, but the quality and innovation are similar.

If you’re considering a Worcester Bosch boiler vs a Viessmann one, you should explore the specifications and prices.

Both brands offer quality boilers. The main difference is the price and the technological features. Compare the two, and you could find your ideal boiler.

Viessmann vs Alpha Boilers

Alpha is the UK arm of European boiler titan Immergas. As such, the company has a global reach and a vast product offering.

Much like Viessmann, Alpha offers a selection of domestic and commercial boilers for both residential and industrial clients.

With a 4.7-star review on Trustpilot, Alpha is another boiler manufacturer with a slightly higher ranking on the site than Viessmann.

While both brands offer sustainable boilers, Alpha takes this one step further with its Gassaver boxes. These small boxes sit on top of the gas boiler and extract heat from the gas that leaves it.

This design takes the heat from the gas leaving the boiler flue and uses it to preheat the cold mains water before it enters the boiler. As such, it can make any gas boiler more sustainable.

Alpha’s longest warranty is 13 years. However, most of its boilers have a standard warranty of just 5 years.

Therefore, Alpha has the edge over Viessmann when it comes to the maximum length of its warranty. Alpha’s boilers and products are also somewhat cheaper than Viessmann’s.

Keep in mind that price isn’t always an indicator of quality. In this case, both brands aim for reliability and quality. With different technology, features, and models, each of these two brands could be a great choice for your home.

Viessmann vs Ideal Boilers

Established in 1906 under the name National Radiator Company, Ideal Heating is now an industry-leading boiler provider with clients worldwide.

It’s a pioneer in the boiler industry. In the 1920s, it made the Ideal Cookanheat, which combined a cooker, boiler, hot space for drying clothes, and open fire into one handy unit.

Today, Ideal Heating provides a wide range of boilers and heating solutions. Like Viessmann, the manufacturer offers its products to domestic and commercial clients.

Ideal Heating has a 4.8-star rating on Trustpilot. This puts the manufacturer slightly above Viessmann’s 4.5-star rating.

When it comes to the quality of parts, Ideal is slightly behind Viessmann because it outsources the manufacturer of some of its parts. This is the reason why Ideal boiler prices are slightly lower.

That means that the quality might not be what you expect. Viessmann produces all of its boiler parts in its German manufacturing plant, so it boasts much better quality control.

Also, while Ideal does use a stainless steel heat exchanger and bronze fixtures for some of its boilers, they’re not available on all models, which heavily rely on plastic.

Viessmann, on the other hand, does not use as much plastic in its boilers. Instead, it uses robust brass parts. All boilers come with the brand’s stainless steel Inox-Radial heat exchanger.

These quality components are part of Viessmann’s focus on innovation. Ideal might have started as a pioneer, but today, the brand is slightly behind with its gas-condensing boilers.

Viessmann has a well-regarded app that offers cutting-edge features. Users rate it highly, with a 4.6-star rating on the Apple App Store.

Viessmann vs Ideal boiler 

Ideal also has an app with just 1.6 stars on the same app store. Users don’t find it particularly user-friendly.

In this case, Viessmann could be the better choice for your new boiler. The brand can deliver quality products and fantastic customer service if anything goes wrong.

With innovative technology and an intuitive app, Viessmann is a great choice for modern homeowners. Ideal Boilers might become out of date in the future and the components are not as lasting as Viessmann’s.

Viessmann vs Glow Worm Boilers

Part of the Valliant Boiler Group, Glow Worm is the company’s affordable arm. As such, it provides a more cost-effective product with the same reliability.

We’ve already mentioned the quality and innovation of Valliant, and how they stack up against Viessman.

Glow Worm is similar to its parent brand. Many of Glow Worm’s gas boilers are cheaper than Valliant’s because they are slightly less energy-efficient.

Both brands are respected by clients around the world. Glow Worm has the backing of its renowned parent company. Meanwhile, Viessmann has an international reputation and award-winning boiler tech.

When choosing a boiler, do your research. Consider more than just the brand and its reputation, and look at the boilers each manufacturer offers and the features they provide.
