HVR awarads

Viessmann has won a highly coveted HVR Award at this year’s ceremony, clinching the top spot in the Commercial/Industrial Heating Product of the Year category for its new Vitocrossal 100 boiler.

Viessmann launched the Vitocrossal 100 – an exceptionally compact floor-standing commercial boiler – earlier this year, and it is already being specified and installed in buildings where plant room space is limited. The boiler’s small footprint was achieved by the design of an innovative new stainless steel heat exchanger. It is the first floor-standing gas-fired condensing boiler on the market to feature Lambda Pro technology for optimum performance and efficiency. There’s a choice of seven Vitocrossal 100 models, ranging from 80 to 320 kW, plus the option of a twin cascade within a single casing for up to 640 kW. As standard it delivers the benefits of a high water content boiler with no minimum flow rate requirement, no boiler pump requirement and subsequent savings on electrical running costs.

 Jonathan Grist, Viessmann commercial sales director, who collected the award at the London event, commented: “We are delighted that Vitocrossal 100, the boiler that can get to places that others can’t, has been recognised with this HVR award as a star industry product. The response from installers has been exceedingly positive and we expect it to be a popular choice for schools, offices and other space-restricted buildings.”

Organised by Datateam Business Media, and in its eighth year, the HVR Awards is a celebration of innovation and excellence in the heating and ventilation industry.

Modern buildings need to cool down

Spring is coming (slowly) but not everyone will be welcoming the warmer weather. Some of the modern and well-insulated buildings that offer ultra-low heating bills throughout the winter can become fatally warm as the mercury rises. Has insulation become too effective?


Structural insulation is incredibly effective at keeping heat inside a building and modern building regulations have increased the minimum standards to minimise energy use. Continue reading

Keep Hot Water Hot To Beat Legionella

The legionella bacterium is deadly and tepid water is its breeding ground. Keeping water hot doesn’t just save energy – it can save lives too.

The role of insulation in preventing Legionella disease

It’s one of those frustrating things that everyone has encountered – you turn the hot tap on and the water runs cold for a minute or more. What most people aren’t aware of is that this can be more than just frustrating – domestic hot water (DHW) is designed to be maintained at temperatures of more than 60°C for the specific purpose of preventing bacterial growth.
