Tailor-made system solutions for all energy sources

When it comes to convenient heat generation, Viessmann has various technologies to offer. Our technologies are designed to be used for a wide variety of applications. We have tailor-made system solutions for all energy sources and for all types of residential building.

Whether you are looking to install a new boiler in your new build property or you are looking to install a new boiler in your older property as part of a modernisation project, we will have the solution for you. We have solutions for every size of property from flats to detached houses, whilst on a larger scale we also have systems to accommodate the needs of major housing developments.

Our comprehensive range includes a range of fuel options, including gas and oil, along with renewable technologies such as biomass, solar thermal systems and air source and ground source heat pumps.

What makes our boiler range so special though, is the innovative technology used within each model of Viessmann boiler.

Viessmann system technology

All of our gas boilers meet the requirements demanded by efficient condensing technology. This means that 98 percent or more of the energy used is converted to heat. By choosing a Viessmann gas condensing boiler, you will be making a positive contribution to protecting the climate and the environment.

Designed to be future proof, all Viessmann heating systems are compatible with a range of fuel sources, meaning you can use a solar thermal heating system in-conjunction with your gas boiler to provide domestic hot water backup and find yourself enjoying lower energy bills, whilst also making an even larger positive contribution towards protecting the climate and the environment.

The combustion controller featured within our Vitodens 200 range is designed to automatically adjust to various gas types, including biogas mixtures, meaning these heating systems are equipped to be used with sustainable fuels.

Viessmann renewable technologies

If the above was not enough, the Viessmann range of heating systems also features systems utilising fully renewable technologies. These include solar thermal systems to heat domestic hot water and provide central heating backup, plus biomass boiler options which utilise logs, woodchips and pellets to generate heat. We also offer a number of hybrid devices, including heat pumps which exploit heat from the ground, the groundwater and the ambient air.

Weather compensation

A simple but incredibly effective Viessmann technology is Weather Compensation, available with our Vitodens range of condensing boilers. Consisting of a simple outdoor sensor and Weather Compensation controls, our Weather Compensation technology harnesses the natural signals provided by the elements to adjust the temperature inside your home based on the temperature outside. Utilising this technology can assist you in saving up to 15% more fuel each year, whilst also ensuring a pleasant indoor temperature, whatever the weather.

The difference weather compensation makes

When the temperature changes outside the boiler responds and starts to increase or decrease the radiator temperature to compensate. This proactive mechanism means that people inside the building won't even notice that the temperature has changed outside. For example, when the outside temperature drops at night, more heat is lost through the walls of the building. Because the outdoor sensor detects the fall as soon as it happens, the boiler is able to raise the radiator temperature and keep the inside temperature stable. With a conventional system, the temperature is dependent on a room thermostat, which will only take effect after the inside of the building has become too hot or too cold.

In summary, weather compensation controls enable the boiler to respond to outside temperature changes and adjust the radiator output, to maintain a constant temperature indoors.

This boiler flow diagram helps to demonstrate how this compares to a heating system without weather compensation - where the boiler runs very hot then very cold as it constantly 'plays catch up' to achieve the desired room temperature.
