Faced with the high cost of running its oil-fired boilers and an £80 000 cost to install a gas main, Canons Brook Golf Club near Harlow has opted for a biomass installation. Ivor Marshall, chairman of the club, explains, ‘The costs to prepare and install a gas system made no financial sense, so we turned our attention to renewable sources.’

Cascading control

06 January, 2014

Cascade heating systems comprising multiple boilers are ideal for adapting to changing heat loads and also supporting a biomass boiler without adversely affecting RHI payments — but only when they are controlled effectively. Kevin Stones of Hoval explains.

Rinnai, DHW, boiler, space heating

Rinnai has developed controls for its Infinity range of condensing gas-fired continuous-flow water heaters that are compatible with the popular forms of building-management systems used in buildings. The technology seamlessly integrates the company’s hot-water systems into BMS protocols to provide ultimate control and maximise energy efficiency in large buildings, including multi-tenanted sites.

Stokvis, heat interface unit, boiler, space heating

Stokvis Energy Systems has responded to the growing popularity of communal- and district-heating systems with the introduction of the H-Series Econoplate interface units. There is a choice of single and twin plate units to provide heating and hot-water services within dwellings such as apartments, student flats and sheltered-housing schemes.

Atag, cascade, rig, boiler, space heating

An installation rig for Atag Heating’s Q Series condensing boilers enables up to three boilers to be installed in cascade operation. The rig is only 1.5 m high and enables boilers to be installed in a variety of configurations. Q Series boilers modulate down to 16% of full output and are up to 109.3% efficient. These rigs offer outputs from 9 to 172 kW.

Fulton, DHW, boiler, space heating

Fulton’s FHE-250 modular hot-water boiler has an output of 250 kW and features a fully condensing stainless-steel heat exchanger. The modular design means that several boilers can be combined to suite any application and hot-water requirements.

Spirax, steam, boiler, space heating

Spirax EasiHeat engineered systems for delivering hot water and heating on demand have been enhanced to achieve energy savings of up to 20% compared to conventional steam-to-water heating systems. EasiHeat now features the Spirax Intelligent Monitoring system (SIMS) control and monitoring display technology that makes it easy to save energy and control critical applications.

Adding CHP to the boiler mix

06 January, 2014

With a number of stakeholders looking at ways to enhance energy-efficiency levels, a systems alliance can often prove to be the most effective option. Pete Mills of Bosch Commercial & Industrial Heating, explains this concept and how adding a combined heat and power module to the ‘boiler mix’ can boost performance.

The BIM-wash-free style of last year’s event will continue. Speakers will cover all aspects of BIM — from the design of built assets through to their day-to-day management.

CIBSE has become aware of potential hazards in some biomass boilers when operating in slumber mode. The concern is that partial combustion might occur — generating unburned flue gases, including carbon monoxide. The institution is working to provide further guidance. In the meantime the following advice is offered.

Co-heating tests to measure the overall heat loss from buildings are inconsistent and highly sensitive to the weather, according to research by the NHBC Foundation. The study warns that doubts about the accuracy of the co-heating tests means that in its current form it is not a suitably accurate tool for reliably evaluating energy performance.

Heatrae Sadia

Heatrae Sadia has sharpened up its image with the creation of a new brand image and strap line. The logo has a crisp contemporary design, and the new strap line reflects the company’s commitment to delivering energy-efficient and intelligent hot-water products.

Adrian Walker, chairman of the ICOM Energy Association, which represents the industrial and commercial heating industry, has criticised ‘contradictory messages’ that seem to fly in the face of the need to address rising energy prices by using energy more efficiently. Opening the recent ICOM winter conference, Adrian Walker, who is managing director of boiler manufacturer Hoval, said, ‘There has been a frighteningly quick pace of change in energy prices over the last few years, accompanied by commercial pressures to get more from less — including heating energy.
