Design and Technology

When choosing a Viessmann gas boiler, you will not only be buying one of the most efficient and effective boilers on the market - you will also be making an investment for the future. Our best-selling Vitodens gas boiler range has models to suit all property types and, whichever you choose, you can rest assured it will provide you with reliable and cost effective heating and hot water well into the future.

Featuring the Lambda Pro Control combustion controller, the gas condensing boilers within our Vitodens 200 range will automatically adjust to any gas type. This includes biogas mixtures. In addition, each of our domestic gas boilers can be used with Viessmann solar technology, enabling you to harness the free energy provided by the sun. For applications on a bigger scale, the Vitodens 200 is also suitable for cascade up to 900 kW.

As well as offering superior performance, our Vitodens gas boilers are renowned for being exceptionally user-friendly and easy to operate. They have all been designed with smart technology in mind, meaning you can control your comfort and save money from wherever you happen to be.

Inox-Radial heat exchanger 

All wall-hung gas boilers from Viessmann feature our unique stainless steel Inox-Radial heat exchanger. This is designed to provide reliability over the long term, as well as to enhance performance. It is also self-cleaning.

This heat exchanger ensures high heat transfer through laminar hot gas flow across defined gaps. It also benefits from impressive corrosion resistance thanks to the use of high grade stainless steel and thick walls. Because we’re so confident in its design, we provide a 10 year warranty against corrosion. 

Saving energy and protecting the climate with condensing technology

Condensing boilers are extremely efficient. In fact, replacing an old G-rated non-condensing model with a new high efficiency condensing boiler could save your household hundreds of pounds a year on your energy bills.

Viessmann gas condensing boilers convert up to 98 per cent of the natural gas they use into heat, meaning more of the money you spend is converted into warmth and hot water for your home. As well as being good news for your finances, this is beneficial for the environment as it will help you to lower your carbon footprint.

Our gas condensing heating systems are future-proof too as they are suitable for use with different types of gas which may become more important in the future.

Proven technology for industrial  / commercial applications

We also provide a variety of floor standing gas boilers that can be ideal for a diverse range of applications, including heating for commercial and public premises, industrial plants, and apartment buildings.

Like all of our technologies, these boilers are exceptionally reliable, long-lasting and efficient. They are also low-emission and as well as being designed to comply with current legislation, they will continue to meet the required standards even as emissions limits become more stringent.

Smart home ready

We ensure that all of our domestic gas boilers are easy to control through smart technology. Our dedicated interface and app make it quick and simple to operate your heating system via your computer or smartphone, wherever you are.

Depending on the model, these features may include additional heating circuits, in-built software for remote data communication and monitoring, safety monitor sensors, a solar/heat pump interface and automatic commissioning functions.
