Being selective about bidding is a positive step for the industry, says John Daly of LJJ

boiler, space, heating, DHW, BSRIA, Evinox, heat interface unit, HIU

Evinox’s ModuSat heat interface units (HIUs) have been independently tested by BSRIA and surpassed the benchmark requirements set out in the CIBSE ‘Heat network code of practice’ for both duty and return-temperature performance. The results demonstrate that ModuSat units can achieve a ∆T of up to 65 K between flow and return temperatures, thus optimising the efficiency of a heat network.

boiler, space, heating, DHW, condensate, Sentinel Commercial

Sentinel Commercial’s Condensafe C4000 device is designed to neutralise condensation from commercial condensing boilers. It is designed to fit into a standard 40 mm ABS/PVCu waste pipe drain and is fitted with universal couplers to accommodate all makes of plastic pipe with a diameter of 40 mm.

boilers, space, heating, DHW, Remeha

Heating and hot-water services for 54 flats and communal areas in sheltered accommodation in Bath can now meet the demand following an increase in the size of the gas-supply pipework, which was inadequate before, and the installation of two Remeha Gas 210 Eco Pro 4-section condensing boilers and two direct gas-fired water heaters. Combe Park Almshouse is the latest addition to the St John’s Hospital’s portfolio of almshouses.

boiler, space, heating, DHW, Hoval, district heating

As district heating increases in popularity it is important to pay close attention to every aspect of the system design if optimum performance is to be achieved. Geoff Lord of Hoval explains.

boiler, space, heating, DHW, Advance Appliances, thermal store

Advance Appliances has updated its SFUTS multi-fuel thermal store by fitting and pre-wiring two electronic timers to it. The first timer is for the boiler to avoid overnight firing. The second is for the wood-burner input, with the timer turning off the pump on this circuit so that all the captured heat is kept in the store and not recirculated through the wood burner.

boiler, space, heating, DHW, Mikrofill

Hampshire’s first ‘super school’ has its heating and hot-water requirements met by a number of boilers from Mikrofill. They comprise numerous Ethos wall-mounted 90 and 110 kW condensing boilers.

boiler, space, heating, DHW, Potterton Commercial

Trying to plan for five, 10, or 15 years from now is tough in any business — but never more so when the heat is on to specify and build a commercial project to time and budget. However, making smart choices at the design stage is vital to cost efficiencies and, ultimately, return on investment. Neville Small at Potterton Commercial, explains why investing in quality products and equipment makes for a better project in the long run. 

boiler, space, heating, DHW, Elco UK

On paper at least, 2016 should be a ‘business as usual’ year for the commercial heating sector, but could this be the year where we see boilers specified in a new way? Could they now take on a supporting role to alternative heating technologies such as CHP? If so, what are the key elements of a system to consider? Gavin Watson of Elco UK, looks at the options.

boiler, space, heating, DHW, Ideal Commercial Boilers

Andrew Dabin of Ideal Commercial Boilers, reflects on the challenges facing building-services engineers who are undertaking boiler retrofit projects post-ErP and how manufacturers can help uncover solutions that will minimise capital outlay whilst delivering a high-efficiency heating system.

boiler, space, heating, DHW, biomass, renewable energy, wood pellet, Windhager

A Scottish hotel on the banks of Loch Ness has slashed its heating and hot-water costs following the installation of two wood-pellet boilers to completely replace LPG boilers and electric storage heaters. The combination of fuel-cost savings and payments from the Renewable Heat Incentive (RHI) amounts to about £26 700 a year and are almost evenly split.

boiler, heating, space, DHW, dry cycling, Sabien Technolgy

Preventing boiler dry cycling at the King’s Cross Hospital in Dundee has achieved average fuel savings of 7% with a payback of 1.8 years. Sabien Technology verified the savings for its M2G boiler-load optimisation controls for NHS Tayside.

boiler, space, heating, DHW, Hamworthy Heating

Technologies such as combined heat and power and biomass boilers should not be regarded as distractions to ensuring that the gas-fired boiler plant that is still required operates as part of an efficient system — even before other technologies are added. Stuart Turner of Hamworthy Heating gives an insight.

commissioning, balancing, SAV Systems, valve, TRV

The PT40 range of radiator control valves from SAV Systems helps to reduce energy waste in heat networks by ensuring that radiator systems are well balanced. These TRV sets are presettable to a flow-rate limit at each radiator, in line with the CIBSE ‘Heat networks code of practice’, eliminating the need for traditional balancing.

commissioning, balancing, tracer dye, pre-commission cleaning, Water Treatment Products

The addition of a tracer dye to its products for pre-commission cleaning is said by Water Treatment Products to be a major step forward. WTP tracer dye enables contractors to accurately measure the concentration of chemical cleaners as they are added to the system

commissioning, balancing, Siemens, PICV

The only information needed to the size of Siemens Acvatix PICV (pressure-independent control valve) is the required flow through it, saving time for the specifier. These valves automatically shield against pressure fluctuations in a network to maintain a constant flow. The are available in sizes from 15 to 150 mm (a 50 mm size is pictured).

commissioning, balancing, manifolds, Marflow Hydronics, fan coil unit

Grouping a number of terminal units together with a manifold offers major benefits for installation and commissioning. Nick Martin of Marflow Hydronics takes a look at their real advantages.

commissioning, balancing, EPIV, Belimo

Belimo’s EPIV pressure-independent characterised-control valve is available in sizes from DN15 to DN150. These valves combine the four functions of measuring, controlling, hydraulic balancing and bubble-tight closing. They provide real-time information of the measured flow rate.

commissioning, balancing, Albion Valves

What do the performance gap and uncomfortable buildings that are energy inefficient have in common. Paul Wightman of Albion Valves believes poorly balanced systems are often to blame.

commissioning, balancing, Hydraquip, double shut off coupling

Hydraquip has launched a new range of double-shut-off couplings for the commercial H&V and air-conditioning sectors. Hydraquick couplings can be connected and disconnected without having to shut down or drain the system. Terminal units can also be looped out during the flushing process.

commissioning, balancing, Commissioning Specialists Association, DPCV, PICV, EPIV

‘Self-balancing valves’ and ‘automatic balancing valves’ means that there is no need for a commissioning engineer. Right? Tony Anderson, chairman of the Commissioning Specialists’ Association’s training committee believes that the commissioning engineer’s role is more important than ever.

chiller, York, Johnson Controls

The transactional web site launched by Johnson Controls a year ago to enable engineers to purchase spares on line has proved to be a multi-million success. The EasyParts web site enables engineers to purchase major spares such as compressor rotors, valves and motors online.

Glenigan

The value of new projects starting on site (excluding projects valued at over £100 million) was 4% lower during the three months to November than a year earlier, according to figures from Glenigan. There were declines in both residential (-2%) and non-residential (-4%), but the overall figures were made worse by an 8% decline in civil engineering.

climate change, COP21, Global warming

The pressure, or even incentive, on all countries throughout the world to reduce carbon emissions has taken a major step forward with the agreement of 195 countries at the recent COP21 conference to ‘pursue efforts to limit the [global] temperature increase to 1.5 K above pre-industrial levels, recognising that this would significantly reduce the risk and impacts of climate change’. The more immediate agreement at the United Nations Climate Change Conference in Paris from 30 November to 11 December was ‘holding the increase in the global average temperature to well below 2 K above pre-industrial levels’.
