Seaview International Holiday Park at St Austell in Cornwall boasts exceptionally high-quality shower blocks and is enjoying significant savings in fuel consumption since the installation of Rinnai continuous-flow water heaters to replace the stored-hot-water system. One benefit for visitors is that the showers will never run out of hot water.

maintenance, refurbishment, Remeha, boiler

When the aging atmospheric boiler and heat exchanger at a distillery in Somerset started to fail, the owner of Burrow Hill Farm, Julian Temperley, installed a Remeha Quinta Pro 30 LPG boiler to halve fuel consumption. It is used for pasteurising the farm’s apple juice and in the fermentation of the company’s award-winning Burrow Hill Cider. The farm also distils its cider into Somerset Cider Brandy.

maintenance, refurbishment, Flakt Woods, ventilation, AHU, air handling unit

A reversible hat pump and a thermal wheel are key features of a Flakt Woods ventilation system installed as part of the refurbishment of the Arundel Building at Sheffield Hallam University. The system can supply up to 2.5 m3/s of conditioning air into a VAV (variable air volume) system and incorporates inverter-driven compressors. It replaces a natural-ventilation system.

maintenance, refurbishment, Adcock, air conditioning

Adcock Refrigeration & Air Conditioning has taken action to help businesses better understand why regular maintenance of their air-conditioning system is important. A comprehensive fact sheet has been prepared to help those who are not yet aware of recent changes in EU legislation affecting refrigerants. There are thought to be thousands of SMEs in the UK that are still not aware of the rules, mainly because they do not have a maintenance plan.

maintenance, refurbishment, Euroheat, biomass, spaceheating, boiler, renewable energy

Hartpury College in Gloucester is looking forward to reducing its energy bill of £800 000 a year following the replacement of oil-fired heating plant with a biomass district-heating system. The project will qualify for payments from the Renewable Heat Incentive of nearly £80 000 a year. Euroheat supplied the system for this residential agricultural and sports college, which has over 1300 students.

maintenance, refurbishment, Timoleon, underfloor heating

Faced with the huge cost and disruption of replacing an underfloor heating at a Grade 2-listed home in Cambridgeshire, its owners found a solution with Timoleon’s ToronFloor and LowBoard low-profile system.

Following the successful installation of Adey’s MagnaClean Commercial filter in the heating system at Fairfield Health Club at Stotfold in Bedfordshire, Bannatyne Health Clubs now specify it as part of plant efficiency upgrades.

maintenance, refurbishment, legionella, Rinnai, DHW, hot water

Many of the problems associated with controlling legionella bacteria in domestic-hot-water systems can be solved by choosing to install a gas-fired continuous-flow system, explains Chris Goggin, associate director with Rinnai UK.

maintenance, refurbishment, SSE Enterprise Energy Solutions, Siemens, BMS, building management system

RS Components has upgraded the building-management system in its distribution centre at Nuneaton to improve energy efficiency. Installer SSE Enterprise Energy Solutions worked with the company to upgrade the BMS for the 160 000 m2 facility to a Siemens Desigo design.

maintenance, refurbishment, Mitsubishi Electric, air conditioning, VRF

Cloud-based software company Software Europe has marked its 25th anniversary with an overhaul of the building services at its Lincoln headquarters, with the help of a finance package from Mitsubishi Electric. Existing plant included a 15-year-old AHU with a gas-fired LTHW coil and a DX chiller coil ducted-air system. The parts were obsolete and failing, and there was poor temperature control in the building. The new equipment has reduced costs by over £12 000 — much more than the interest payable.

maintenance, refurbishment, Kamco, descaling pump, pipework, water treatment

Kamco descaling pump

01 July, 2015

Kamco’s Scalebreaker C210 tank-mounted descaling pump is designed to increase safety by keeping descaling chemicals enclosed at all times within the tank, hoses or equipment being descaled. Applications include the chemical cleaning of calorifiers, boilers, plate heat exchangers and cooling circuits.

maintenance, refurbishment, Rinnai, DHW, hot water

Windrush Leisure Centre in Witney, Oxfordshire, has replaced three poorly performing gas direct-fired water heaters with Rinnai Infinity continuous gas-fired water heaters. The three HDC1500 water heaters are on a secondary return system, so there is no need for storage.

maintenance, refurbishment, air conditioning, data centre, Airedale, Denco

Annual energy-cost savings of over 70% are expected at the Warton site of BAE Systems following upgrading of computer-room air-conditioning (CRAC) systems. The savings of £350 000 a year should recoup the cost of the project in just 15 months. The requirement was for a cost-effective upgrade to increase cooling performance and efficiency without disrupting the testing and production of combat and training aircraft such as the Typhoon and Hawk advanced jet trainer.

maintenance, refurbishment, Sentinel Commercial, water treatment, inhibitor

Poor-quality water-treatment chemicals can very quickly lead to major problems in heating systems. Ian Barnes of Sentinel Commercial explains how specifiers can ensure the delivery of best water-treatment practice procedures and, therefore, long-term heating system protection.

maintenance, refurbishment, chiller, chilled water, Cool-Therm

Cool-Therm has supplied two low-temperature Tonon chillers for a major replacement project at Swindon Hospital. The project was carried out with Carillion and harnesses the low-temperature performance of these multi-scroll industrial chillers using a reduced charge of R410A.

maintenance, refurbishment, B&ES, SFG20

Although the world is going digital, many buildings remain stubbornly unconnected. Bruce Kirton of the Building & Engineering Services Association (B&ES) explains why this opens up huge opportunities for specialist operation and maintenance contractors.
