Viessmann Boiler Review: Vitodens 100 Compact, Heat Only

If you have a limited amount of space, the Viessmann Vitodens 100 compact boiler can meet your needs and fit inside a kitchen cupboard or bathroom cabinet. This efficient heating system can provide hot water to showers and radiators in a small or midsized home.

Why Should You Consider a Viessmann Vitodens 100 Compact Heat-Only Boiler?

The Vitodens 100 compact heat-only boiler can produce about 23 litres of hot water per minute. What does this mean in terms of actual use in your home? If you have 23 litres of water per minute, you can heat a small or midsize home with radiators and one or two showers or baths at the same time.

In my home, the morning rush is a daily occurrence. As the family prepares for work and school, both bathrooms are in use. Depending on the season, the radiators may be operating as well. With the Vitodens 100, we have always had enough hot water during these busy times.

Is the Viessmann Vitodens 100 Compact Boiler Reliable?

Yes, the performance of this small boiler meets our needs, but what about reliability?

Reliability is as important as performance in my book. Hot water is a necessity. Could you imagine going even one winter day without heat or having to take a cold bath or shower? If your boiler stopped working, you would consider it an emergency and hurry to get a repair technician to your home to fix the problem.

Viessmann is known industry-wide for its reliability. I don't know about you, but I do not only like to rely on reputation alone when I purchase something that I need to work day after day. I prefer to have my guarantees in writing.

All Viessmann Vitodens 100 models have a five warranty. You can extend this to an industry-leading ten years if you have a Viessmann-certified technician install your boiler.

The Vitodens 100 is Very Efficient

Efficiency is the other trait that I was concerned about when purchasing my new boiler. Yes, I am someone who has concerns about the state of the environment. A high-efficiency boiler will reduce carbon emissions from natural gas or propane, both of which you can use to power the Vitodens 100 compact.

The other issue related to efficiency is the cost of operation. Viessmann uses a state-of-the-art stainless steel heat Inox Radial heat exchanger. Similar-sized boilers from competitors usually rely on an aluminum heat exchanger.

The Vitodens 100 can heat water instantly with maximum efficiency, and it can do so with a minimum amount of natural gas or propane. This limits heating costs, which can conserve your money. For me, this has meant switching to a new boiler has been an excellent investment. I am saving a noticeable amount of money compared to my old boiler.

How efficient is this unit? It can operate at up to 95% efficiency, which means that 95% of the energy that it uses goes directly to producing hot water.

The Vitodens 100 Boiler Uses Easy to Use Technology

Other features make this a "smart" boiler. I use "smart" to refer to sensors and controls and also to mean a "smart" choice for consumers.

This boiler model has an optional weather compensation mode. Basically, an outdoor sensor detects the temperature and adjusts the flow temperature of the boiler accordingly. According to Viessmann, this feature can lead to a further 12% savings on energy costs.

You can also make adjustments manually and program the boiler using its LCD control panel. You can also use Tado° thermostats and smartphone applications to adjust the settings in your home and use usage data to find the most efficient settings to help you save further energy costs.

Furthermore, you can adjust the energy output to meet your needs so that you are not heating water that you will not use.

In my opinion, the best thing about these controls is that you can use them without being an expert. I am not savvy when it comes to technology, but I can figure out how to alter the boiler settings with the LCD panel and the tado° application on my phone.

Is This a Compact Boiler?

Size is not something that you always think about with boilers. The Vitodens 100 unit provides on-demand heating, so you don't have to worry about extra tanks or other equipment.

The Vitodens100 can fit easily inside a kitchen cupboard or under the kitchen worktop, so you can get plenty of power without having to sacrifice living space. Also, this boiler is quiet, so you may not even hear it as it performs its vital work in your home.

Efficiency and Reliability in a Compact Package

The compact Viessmann Vitodens 100 heat-only boiler can meet the hot water and heating needs of your home, even if you have more than two showers or baths that are sometimes in use at the same time. Thanks to its technological features, stainless steel components, and efficient design, you can get the performance that you and your family needs without having to pay more in natural gas or propane costs.
