Beyond the boiler

01 September, 2011

Adding solar thermal to existing buildings and boiler systems is an efficient option for property owners who want to reduce carbon emissions and take advantage of the Renewable Heat Incentive says Firat Ucer.

Boilers, Ideal Commercial Heating

Two clicks and you’re out

01 September, 2011

Too many building services control systems are not ‘intuitive’ and ask too much of the end user. The commercial heating sector must take on board the lessons learned by the IT industry and deliver easy to operate solutions, says Ron Barker.

Boilers, package boilers, Potterton Commercial

Potterton Commercial has designed and supplied a Paramount MB package boiler plant for the Heathlands Hotel in Bournemouth. It has 114 bedrooms and is set in its own landscaped gardens in the centre of Bournemouth. It was recently acquired by Britannia Hotels, which noted that the heating system was aged and in a poor state of repair.

Boilers, MHS

MHS Boilers now offers a cascade system for its recently introduced Ultramax Thision L wall-hung boiler. The cascade kit enables a modular system of up to eight boilers to be created and deliver a total output of up to 1140 kW — said to be the most powerful manufacturer-supplied cascade system available in the UK. Three cascade systems are available — wall mounting in line for up to six boilers and freestanding back to back for three to eight boilers.

The theory that will lead to more efficient heating systems served by boilers is often not borne out in practice. Steve Cooper provides food for thought.

Glorious good wood

01 September, 2011

With fuel prices soaring and the Renewable Heat Incentive about to kick in, there has never been a better time to look at wood as a fuel source. Mark Northcott examines what you should look at when considering a biomass boiler installation.

Bio-fuels can be liquid too

01 September, 2011

With a 10% surplus of oil-seed rape being produced in the UK, Harry Howard discusses the potential for liquid biofuels for boilers — aided by the use of other waste oils.

Efficient boilers and heating systems are the result of a combination of technologies and controls techniques. Are you familiar with all the features explained by Paul Sands?

Boilers, Ideal Commercial, LPG

Ideal Commercial now offers a wall-hung LPG boiler as part of its Evomax range. There are four models with outputs from 30 to 80 kW delivering seasonal efficiencies in accordance with Part L of the Building Regulations and low NOx emissions. They can modulate down to 20% of full output.

Boilers, Remeha, wood chip, wood pellet, biomass

Replacing an oil-fired heating system with a biomass boiler from Remeha Commercial is the latest initiative in the campaign to reduce the carbon footprint of the Duchy of Cornwall Nursery at Lostwithiel in Cornwall. This 100 kW boiler serves the newly opened visitors’ centre, shop and cafe building and the new greenhouse area.

Hamworthy Heating is taking its Fleet range of condensing boilers around the country with a roadshow running through to Summer 2012. You can request an invitation to these events, where you will have the opportunity to speak to Hamworthy sales engineers and business-development managers about the Fleet range and the boilers on display.

Boilers, MHS Boilers, DHW

As part of a £20 million redevelopment of halls of residence at the University of Glamorgan in Pontypridd, MHS Boilers has supplied 10 Ultramax 65 kW wall-mounted condensing boilers and 10 Xpressflo 300 l condensing hot-water generators. The halls are on the Treforest campus, and the equipment will be installed in five plant rooms to provide heating and hot water for over 450 new en-suite rooms.

Boilers, Glow-worm

Glow-worm’s Ultracom2 35 Store boiler combines the benefits of a system store and combi boiler in one package and is suitable for new-build properties and retrofit. Hot water can be delivered with a flow rate of 19.7 l/min through a 35 K temperature rise. These boilers have an output of 35 kW and include two storage cylinders within the unit.

Low-carbon meets boilers

01 September, 2011

It is now very common for projects to use more than one heat source for space heating and domestic hot water. Integration and control are therefore fundamental to the system design, says Kevin Stones.

Smedegaard, circulator pumps

Smedegaard’s SimFlex A range of glandless circulators provide all the benefits of variable-speed control and also have permanent-magnet technology to make the motors even more efficient. These pumps are designed to run at a slower speed than many similar pumps on the market, reducing noise levels and maintenance.

Sontay, heat meter, water meter

Sontay has introduced a new series of water- and heat-metering products to help building-services specifiers and contractors achieve precise and affordable flow and energy metering. The range includes flow sensors, ultra-sonic flow sensors, water meters, compact heat meters and heat-meter integrators. These devices conform to the requirements of the Measuring Instrument Directive and EN 1434, where applicable.

Armstrong, packaged pump sets

Armstrong has launched a series of pre-designed packaged pump solutions that offer specifiers low first installed cost, reduced footprint and the opportunity for outstanding energy efficiency. Pumps, pipework, controls and motive power are fully integrated, and the packages are made off site for fast and efficient installation.

Durapipe, Friatherm, plastic pipe

Durapipe’s Friatherm plastic pipework system has been specified for a boiler refurbishment at Hurst Community College in Hampshire. The main boiler house was being refurbished, and a replacement was need for the existing copper pipework that had galvanised and stopped performing to the required standards.

Energy efficiency rules

With EU legislation on the efficiency of electric motors starting to come into effect, and continuing to do so for the next six years, we look at the implications for pumps

Efficiently commissioned

01 September, 2011

Are you one of the crowd that regards commissioning as an expensive luxury? Let Graeme Waugh try to convert you.

Grundfos, pumps

The Grundfos ‘Thinking buildings universe’ web site offers building-services professionals a centralised information point that is a one-stop shop for the applications of pumps for commercial building services. The site has been designed to work as an aide during the planning and specification stages, as well as when the selections have been made and systems are operational. At all points during the development of the new system, potential users provided input on what they expected, needed and wanted from such an information hub.

Kamco, descaling

Kamco’s ScaleBreaker FX is a vigorous chemical descaling agent that dissolves limescale, rust and corrosion deposits. It can be used to remove scaled from boilers, air-conditioning plant and heat exchangers. The product is circulated through the equipment to be descaled. It reacts immediately, taking deposits into solution. The evolution of carbon dioxide provides visual monitoring of the descaling process.

Grundfos, pumps

Grundfos offers a pump-refurbishment service that is designed to ensure that the energy and cost savings achieve their full potential. It is estimated that 70 to 80% of commercial buildings that will exist in 2020 are already built, emphasising the importance of refurbishment to achieve energy savings. In some cases, a pump refurbishment can reduce its energy consumption by up to 80%.

The British Pump Manufacturers’ Associations’ directory and buyers’ guide’ for 2011/12 provides key information about members’ products and services and an update on current directives affecting the pump industry. A new-products section has been added to provide an update to new innovations.

Spirax Sarco, steam, heat exchanger

Aberdeen Royal Infirmary has reduced the cost of providing heating and hot water by 15% by converting from shell-and-tube calorifiers to EasiHeat systems from Spirax Sarco. In addition, up to three weeks’ of maintenance work has been saved each year as the old systems had to be stripped down for regular insurance inspections.

Are the pumps in your heating or chilled-water system using anything up to five times more energy than they need to? Dr Arnold Teekaram outlines how to design systems that are inherently more efficient.

Zehnder, BIM objects, radiators

Zehnder has enhanced its range of architectural services to train, support and inform the architectural, engineering and construction industry in the specification and installation of its products. In particular, Zehnder provides parametric BIM (building information modelling) objects for its product range. Designed as fully parametric Revit families, the BIM objects can be downloaded from Zehnder’s web site.
