Pegler Yorkshire’s Panacea range of mixer taps for baths take a different approach to design by using one hole in a bath for the water outlet and the other for its control. Called Panacea, these taps are part of the Francis Pegler range.

Savings in water costs and protection against damage caused by burst pipes is provided by a system from Waterguard Services. Wayne Strachan, a director of the company, says, ‘A fractured 15 mm pipe can deliver a huge volume of water in just a few minutes, but bursts often go un-noticed for hours or even days.

Glow-worm’s Ultracom2 35 Store is a high-efficiency combi boiler that combines the benefits of a system store and combi boiler in one package. It can serve properties of four to five bedrooms with a high demand for hot water. The flow rate is 19.7 l/min at a 35 K temperature rise. Available as a 35 kW model, this boiler includes two 21 litre insulated cylinders with a reheat time of less than five minutes.

Domestic hot water for seven recently completed luxury holiday cottages in the grounds of a 12th-century Cistercian priory in North Yorkshire is provided by a recirculation system using lightweight Microflex PE-Xa multi-core pipes in HD-PE outer jackets. Supplied by Watts Industries, the pipes were chosen for their energy efficiency and ease of laying into an underground ring circuit connecting the cottages to the central plant room of Syningthwaite Priory.

Contractor H2O Plumbing & Heating Services now uses Durapipe’s SuperFlo pipework system as the standard specification for cold-water following its successful application in a new apartment development. Also, compared with copper, this plastic system overcomes the risk of thefts from site.

The temperatures that render hot water safe from bacteria are nevertheless dangerous to people — but there is no need for this risk, as Terry Rowbury explains.

Taps that are inadvertently or deliberately left running, taps that drip, urinals that flush when they are not needed and leaking flushing mechanisms have the potential to waste large amounts of water in commercial washrooms. Lee Thompson offers a solution.

Dimplex’s EC-Eau range of hot-water cylinders includes models for use with renewable-energy systems, as well as an extensive range of standard direct and indirect unvented cylinders with a number of energy-saving design features. The range exceeds CHeSS best practice for standing heat losses and offers the same performance levels as the existing SCxn range.

Grundfos pumps with energy-efficient Blueflux motors are used in the new design of Aquatec Pressmain’s Aquamatic AMV 2020 range of cold-water booster sets. The latest technology and manufacturing methods are used in the production of these units, enabling their cost to be reduced and the saving passed on to clients.

An 8-year programme of improvement work by the University of Liverpool on a wide range of buildings on three separate campuses has involved Stokvis Energy Systems supplying plate heat exchangers to ensure the quality and safety of the provision of domestic hot water. Dozens of Econoplate units have been installed in halls of residence, lecture buildings and administrative buildings in the city centre, Sefton Park and Leahurst Campus.

Even though water is a renewable resource, it can be a variable resource — so using it efficiently is a major issue.

Water costs have been halved at the Ricoh Arena following the installation of Micronics clamp-on ultrasonic flow meters to monitor water consumption. Alan Pickering, deputy facilities and energy manager at the arena, explains, ‘Water consumption is a big issue on the site, which led us to invest in the installation of three Micronics Ultraflow 2000 clamp-on flow meters in 2009, which we use with an on-site monitoring and targeting system to manage the significant water consumption on the site.’

Douglas Delabie’s ES L-Pattern thermostatic mixing valve is said to be up to 40% quicker to install than other valves. It is designed for use with wash hand basins, showers and bidets in higher-risk and healthcare applications. This TMV enables the temperature of water to a bath to be set at a maximum temperature of 44 to 46°C to minimise the risk of scalding.

To achieve compliance with the temperature-safety regulation in the new Part G of the Building Regulations, Reliance Water Controls offers a selection of TMV2-approved thermostatic mixing valves to suite domestic systems. These valves provide precise and stable temperature control and protect the user against thermal shock if either the hot- or cold-water supply fails. They are approved by WRAS and Buildcert to the TMV2 scheme for thermostatic mixing valves in domestic properties.

Alan Stevenson explains the rationale behind the latest revisions to Part G of the Building Regulations — and routes to compliance.

Installing new showers and instantaneous water heaters to replace a boiler/calorifier installation supplying traditional communal baths at Roundhegians Rugby Football Club in Leeds will make considerable savings in fuel and water consumption. The 16 new showers are used by senior and junior rugby teams, with water heated by four FastFlo instantaneous water heaters from Andrews Water Heaters.

With continuing huge gas bills from antiquated DHW equipment in one of its housing projects, Lambeth Living has replaced it with system comprising a Mikrofill Ethos stainless-steel condensing boiler and a Mikrofill Extreme DHW loading system.
