The air ratio (lambda) – namely the ratio of gas and air – is measured using an ionisation electrode. Depending on the results of the measurement, the automatic control then adjusts the air supply so that there is an ideal gas/air mixture at all times. This eliminates the need for adjustment or readjustment work during installation. This method of operation not only makes the Vitodens products very efficient, but the Lambda Pro Control Plus also ensures a high level of operational reliability. In addition, the flue gas inspection intervals are extended from two to three years. Also in 2018, the company built a solar park next to its headquarters in Allendorf to cover up to 7percent of the company's own electricity requirements. The plant has an output of 2MW and was built without state subsidies. Instead, the project is financed by the company's own consumption of electrical energy.

Air source heat pumps serve as a great alternative to conventional heating systems, as they enable you to generate your own heat and could help you to reduce both your energy bills and your carbon footprint. But what exactly are they and why should you choose one? Scroll down to read more and shop for Viessmann’s air source heat pumps.

Vitodens 100-W/111-W: very attractively priced wall mounted boiler for apartments and detached houses

The Viessmann Group originated in Hof on the banks of the Saale, where Johann Viessmann set up a small workshop in 1917 specialising in the construction of steel boilers. In 1937 he moved operations to Allendorf (Eder) in northern Hesse. After World War II, Hans Vießmann took over his father's company and modernized it by introducing series production and industrial processes. Smart boilers– Every Viessmann boiler comes with the tech you need to stay in control of your heating from your smartphone. An air source heat pump can be a low-carbon form of central heating that moves heat from a natural outdoor element, such as the air, into your home when used in conjunction with renewable energy sources. They can take heat from outside in temperatures as little as -15 degrees and convert it into usable heat, with the help of electricity, to provide you with underfloor heating or hot radiators. For instance, the Vitodens 050-W is a combi boiler that comes with energy outputs of 29 kW or 35 kW. Because they feature a storage tank, system boilers give you a greater hot water capacity than combi boilers. They allow you to use multiple taps or showers at the same time without experiencing a reduction in pressure. This means the appliances are ideal for large or busy households with more than one bathroom. Another feature of system boilers is that they provide water at higher pressure than conventional boilers.

If the boiler is not registered within 30 days of the installation date, then a standard 2 year manufacturer warranty will apply. Viessmann is sponsor of various winter sports.

That said, Viessmann does offer extensive after-sales support should a fault ever develop. For this process to occur, a fan is used to draw air across a heat exchanger (or evaporator). The heat in this air is transferred to a refrigerant circulating through the evaporator causing it to change from liquid to vapour. A compressor, using electricity, then compresses this vapour causing it to rise in temperature. At this high temperature, the heat is then suitable for transferring to the heating and hot water systems in your home.

Our customer services and technical teams are happy to talk you through any questions you may have relating to your Viessmann product. In 2007, the government passed a law saying all new boilers must be condensing. Now, gas condensing boilers are the most popular kind in the UK – which is great, since they're much more efficient than other types of boilers. Ownership of Viessmann gas boilers is still fairly small in the UK. Most Viessmann gas boiler owners are happy: 83% of them report satisfaction with their boiler, although this is lower than the average satisfaction rate of 87%.
