This collaboration coincides with an increased uptake of refrigerants with low global-warming potential, such as hydrocarbons and R744.

boiler, space heating, biomass, renewable energy, Hamworthy Heating

Hamworthy Heating has prepared a series of brochures providing extensive technical content on its biomass boiler solutions. This literature provides comprehensive information on Hamworthy’s Pellestar, Firematic, BioMatic and BioFire biomass boiler ranges, offering outputs from 30 to 1000 kW. The brochures provide detailed product specifications and outline the benefits of each range. They also feature 3D plant-room images.

Hybrid systems that combine renewable technologies with traditional boiler systems offer a reliable route to delivering energy efficiency in commercial buildings, argues John Bailey of Vaillant.

Heating — the evolution

06 September, 2012

Advances in heating technology and the increased uptake of renewable energy solutions place growing importance on the role of the manufacturer in advising on smart system design, and the correct selection of product is more important than ever. Mark Northcott, of Remeha Commercial explains.

boiler, space heating, Lochinvar

As part of a multi-million restoration programme, Lochinvar high-efficiency condensing boilers and water heaters have been installed at Abbotsford, the home of famed Scottish writer and poet Sir Walter Scott, to provide space heating and hot water for visitors. The house, near Melrose in the Scottish Borders was designed and developed by Scott himself in the 19th century. He wrote some of his most famous works at the house, which is undergoing much needed repair before re-opening to the public in 2013.

boiler, space heating, Stokvis

The R40 wall-mounted boiler from Stokvis incorporates the latest gas-heating technology to achieve maximum operating efficiencies with minimum environmental impact. For example, CO2 levels are 8.5 to 8.7%, and NOx emissions are less than 39 mg/kWh at 0% oxygen — exceeding requirements for maximum BREEAM credits.

boiler, space heating, Grundfos, condensate pump

Removing boiler condensate

06 September, 2012

Pre-assembled lifting stations for removing condensate from boiler plant have been development by Grundfos. Conlift operates automatically when condensate enters the collection tank and is available in several versions.

A. O. Smith has launched five commercial boilers to complement its range of high-efficiency water heaters and solar systems. Epsilon and Upsilon (pictured) condensing boilers have outputs from 38 to 140 kW and enable the company to deliver a total solution for heating and hot water.

boiler, space heating, MHS Boilers, communal heating, heat interface unit

MHS Boilers has launched a range of floor-standing heat-interface units with an integrated stainless-steel unvented storage cylinder for hot water. Nexus S-FS units provide independent heating and hot water in multi-dwelling developments served by central plant. These units are available with cylinder capacities from 80 to 305 l. Integral storage makes possible a lower output from central plant than systems providing instantaneous hot water.

boiler, space heating, Hamworthy Heating

As modern condensing boilers rise in popularity, Hamworthy Heating’s Technical Director, Bob Walsh, looks at how to maximise the benefits of already highly-efficient boiler models through careful system design.

The development includes 57 extra-care apartments for Housing 21 and 60 affordable homes for West Kent Housing Association.

boiler, space heating, Eclipse Magnetics

Eclipse Magnetics has launched a high-performance filter to combat the build-up of black sludge in domestic heating systems — increasing boiler life and reducing maintenance time. Black sludge reduces boiler heat transfer, and it can cause blocked pipes, radiator cold spots and corrosion. BoilerMag cleans the system by removing both magnetic and non-magnetic debris. It comes with a 3-year warranty.

Maximising performance

06 September, 2012

Commissioning is essential to ensure that heating systems operate at their full potential to maximise performance and minimise fuel costs — says Pete Mills of Buderus, Bosch Group, who argues that trying to avoid the cost of commissioning is a false economy.

Not only does Hoval make biomass boilers in the UK, but it has also installed them to heat its factory and for training and demonstration purposes. Martin Murrish explains how Hoval went about this retrofit project. When retrofitting biomass boilers there are a number of factors to consider.

Advanced Engineering, Guardian, coil cleaner, coil cleaning

Guardian, Advanced Engineering’s anti-microbial treatment for air-conditioning and refrigeration coils is now available in an aerosol can — making the 6-month protection go even further. Guardian was launched three years ago and has become a standard treatment for the ACR servicing engineer. The 300 ml aerosol packs are said to last longer than the original 500 ml spray bottle.

Bitzer compressor

The variable speed that can be achieved with the integrated frequency inverter is the key to the optimum energy-efficient performance of Bitzer’s CSV compact screw compressor. These intelligent compressors use R134a and achieve an ESEER of over five. Applications include air-cooled direct-expansion chillers and heat pumps.
