Sauter’s ecos505 room controller is a single device that can integrate all systems for room automation with demand-led control of room climate, lighting and sunshading. It is a freely programmable BACnet building controller.

Rinnai, DHW, domestic hot water, BMS, BEMS, Building management systems, controls

Rinnai continuous-flow water heaters can be fully connected with building-management systems across multiple platforms — including popular protocols such as Modbus and BACnet. No longer need water heaters be isolated in lonely plant rooms.

Marflow Hydronics, BIM, pipes, pipework

Marflow Hydronics has further developed its web site to enable customers to download relevant technical information, including BIM models, via a new product-downloads section. In addition, all product pages can be captured in PDF format and used as a data sheet.

Micronics, flowmeters, pipes, pipework

Micronic flowmeters have been used at Heathrow Airport’s Terminal 4 to survey energy usage in the heating system. The facilities staff at the terminal have a 5-year plan running to 2019, entitled Quinquennium 6, which includes the redesign of the medium-temperature hot-water system, which previously ran at 120°C. The requirement was to run the system at a lower temperature to be more cost effective, more environmentally friendly and — crucially — safer.

BMS, BEMs, building management system, controls, actuators, Sauter

Sauter’s Vialoq AVM 215 valve actuator provides 500 N of actuating power and has a nominal stroke from 8 to 20 mm. Its compatibility with commercially available valve types makes it well suited for retrofit projects. Synchronous motors are available for 24 or 230 V power supplies.

Sauter’s ecoUnit-Touch room-operating unit has a slick design and can be operated like a smartphone with the touch of a finger. It enables individual room settings to be made easily and elegantly, without impairing the energy efficiency of the system.

space heating, Sabien, Endotherm, Endo Enterprise

Sabien Technology is the exclusive UK distributor for the Endotherm energy-saving heating additive for commercial multi-site heating systems. The agreement with Endo Enterprises (UK) is to supply the additive, which has won a CIBSE award, for commercial boiler heating systems.

Rinnai, DHW, domestic hot water, maintenance, refurbishment

The supply of hot water for the Malvern Hills Caravan Club site is now plentiful and consistent following the installation of four Rinnai continuous-flow water heaters to replace two storage water heaters. The site has 210 pitches and is especially busy from Easter right through to October.

Cloudfm, Lighting, maintenance, refurbishment, Wolseley

Renovating lighting in its national distribution centre is achieving energy savings of over £150 000 a year for distributor Wolseley UK. The savings come from an overhaul of lighting infrastructure inside and outside its main warehouse in Leamington Spa and surrounding offices. Supported by FM company Cloudfm, the quality and quantity of lighting was assessed to look for alternatives to reduce energy use and maintenance.

Sentinel Commercial, Water treatment

Water-treatment regulations and product standards are almost entirely absent in the non-domestic market. Chris Shelton of Sentinel Commercial explains the financial and operational benefits of proactively embracing a best practice approach to water treatment — and how it can be easily and cost-effectively implemented.

Clos-o-Mat, disability, toilet, washroom

Bristol Airport has gone beyond basic requirements in its suitability for use by people with disabilities by installing a Clos-o-Mat Palma Vita wash-and-dry toilet in place of a conventional peninsular WC. The facility measures 3 x 4 m and includes a height-adjustable adult-sized changing bench and ceiling track hoist that are key to a compliant Changing Places.

Grundfos Pumps

An energy check carried out by Grundfos Pumps on an 11 000-student campus at a university in the north west of England highlighted potential energy savings of over 64 MWh a year, with a return on investment of just three years. The savings were achieved by exchanging a number of circulators for more efficient models.

Making a lasting connection

02 February, 2017

Identifying installation issues with pipework at the commissioning stage is vital to prevent time–consuming remedial work after the fit out is complete. Scott James of Viega UK looks at what to consider when specifying pipework and how modern installation methods can help save time and money during and after the project.

Viega, pipes, pipework, press fit, press fitting

Viega now offers its Megapress press-in connection in the UK. The system makes it a simple job to add extra sensors, thermometers, drainage valves or pipe connections to thick-walled pipe. A press-in connection can be installed in a couple of minutes, with an estimated time saving of 80% compared to welding a connection.

Xylem, pump, circulator

Xylem has extended its Ecocirc XL and XLplus range of wet-rotor circulator pumps, enabling increased energy savings for commercial HVAC users. There are two new product groups for hot and cold HVAC applications.

Andrews Water Heaters, domestic Hot water, DHW

Over the next two years, legislative changes will drive manufacturers to design even more energy-efficient water heaters. Here, Jonathan Tedstone of Andrews Water Heaters looks at what’s in store.

Evinox, district heating, community heating, HIU, heat interface unit

Evinox’s ModuSat heat interface unit takes around 15 seconds to reach 55°C from the tap opening, providing an impressive dynamic response. PID control logic, in combination with PICVs and a fast-acting actuator, modulates the primary flow rate to match the demand for hot water or heating demand, with very rapid response to changing loads.

Potterton Commercial, boiler, space heating

Potterton Commercial has made its easier for installers working on light-commercial project with the introduction of its best-value 50 kW Paramount Four boiler and flue offer. For a limited time, contractors can get a free horizontal or vertical flue when they purchase the boiler.

Rinnai, DHW, domestic hot water

Rinnai’s Infinity range of A-rated continuous-flow gas-fired water heaters, are well suited for small business and domestic properties that require high volumes of water at intermittent times of the day. The water is delivered at accurate temperatures for optimum user comfort and safety. Applications include cafes, pubs, restaurants, offices, shops, hairdressers, small commercial units, caravan parks and leisure facilities.

Polypipe, drainage, soil stack

The failing cast-iron drainage system in the 25-storey Millbrook Tower in Southampton has been replaced using a high-density polyethylene system that was installed without the temporary re-homing of any residents. Built over 50 years ago and formerly the tallest building in Southampton, it has a cast-iron drainage system that had started to rust.
