Viessmann is a German manufacturer of heating and cooling systems, including combi boilers. Their range of combination boilers is highly regarded for their energy efficiency and reliability. In this guide, we will take an in-depth look at Viessmann combination boilers, including how they work, their features, benefits, and any drawbacks, as well as their installation, maintenance, and repair.
Chapter 1: What is a Combination Boiler? A combination boiler, also known as a combi boiler, is a type of central heating boiler that is designed to provide hot water and heating in a single, compact unit. Combi boilers work by heating water directly from the mains supply, so there is no need for a separate hot water cylinder or cold water tank. This makes them ideal for homes with limited space, as well as for those who want a more energy-efficient and cost-effective heating system.
Chapter 2: How Do Viessmann Combination Boilers Work? Viessmann combination boilers work in the same way as other combi boilers. They use a heat exchanger to transfer heat from the burning gas to the water, which is then circulated around the heating system or sent to the taps and showers. Viessmann combi boilers also incorporate a modulating pump, which adjusts the water flow rate to match the demand for hot water or heating.
One of the key features of Viessmann combination boilers is their use of a stainless steel heat exchanger, which is highly durable and resistant to corrosion. This means that the boilers are less likely to break down or require repairs over their lifespan.
Chapter 3: Features and Benefits of Viessmann Combination Boilers Viessmann combination boilers come with a range of features and benefits that make them a popular choice for homeowners. These include:

Chapter 5: Installation of Viessmann Combination Boilers Viessmann combination boilers are designed to be easy to install, but it
is important that the installation is carried out by a qualified and experienced heating engineer. The installation process typically involves the following steps:
- Site survey: The engineer will carry out a site survey to assess the suitability of the location for the boiler and to determine the best positioning for the flue.
- Boiler installation: The engineer will then install the boiler, connecting it to the gas supply and water mains, as well as to the heating and hot water systems.
- Commissioning: Once the boiler is installed, the engineer will commission it, which involves testing it to ensure that it is working correctly and safely.
- User instruction: The engineer will provide the homeowner with instruction on how to use and operate the boiler, as well as information on maintenance and safety.
It is important to note that installation costs can vary depending on the complexity of the installation, the size of the boiler, and the location of the property. It is recommended to obtain multiple quotes from different heating engineers to ensure that you are getting a fair price for the installation.
Chapter 6: Maintenance of Viessmann Combination Boilers To ensure the longevity and efficient operation of your Viessmann combination boiler, it is important to carry out regular maintenance. This includes:
- Annual servicing: Viessmann recommends that their combination boilers are serviced annually by a qualified heating engineer. This will involve checking the boiler for any faults or signs of wear and tear, as well as cleaning and adjusting the components.
- Checking the pressure: It is important to regularly check the pressure on the boiler and to ensure that it is within the recommended range. If the pressure is too low, it may not work efficiently, and if it is too high, it can cause damage to the boiler.
- Flue inspection: The flue should be inspected regularly to ensure that it is clear of any debris or blockages, which can affect the efficiency of the boiler and cause safety issues.
- Water quality: The quality of the water in the heating system can affect the performance of the boiler, so it is important to check the water quality regularly and to carry out any necessary treatment.
Chapter 7: Repairs of Viessmann Combination Boilers While Viessmann combination boilers are designed to be reliable and long-lasting, they may require repairs from time to time. If you experience any issues with your boiler, it is important to contact a qualified heating engineer as soon as possible.
