Heating, Ventilation & Insulation
‘ SMART DESIGN’ BOXES WARD OFF THE LEGIONELLA THREAT
Legionella control and risk avoidance thereof are top of the list when designing heating and hot water systems. The whole supply chain – manufacturers and distributors through contractors to endusers – need to plan and design systems to eliminate the risk of Legionella. It is one area where avoidance and prevention are the only sensible action to take to avoid problems further down the road. Our modern lifestyle demands that hot water is available on tap at any time, day or night. So how can installers and designers reduce the fear of Legionella breaking out – and give peace of mind to customers and end-users? Quite simple – limit the volume of storage on your hot water system.

The Plumbing Group Limited
The Plumbing Group Ltd are said to be at the very forefront of water heating technology. Through their range of Unvented Venturi Cylinders and new 3S technology, the world’ s first‘ Self-Sustaining System’ was created in which the internal expansion device is constantly replenished. The 3S Technology cleverly uses fluid dynamics in order to create a negative pressure. This pressure is known as the‘ Venturi Effect’. The precision of the design means that enough air is allowed to be drawn through in order to recharge the air gap as the tank is filled. All cylinders are WRAS approved and come with a 25-Year cylinder warranty and a 3-Year parts warranty. Sizes range from just 80 Litres and go all the way up to 500 Litres and are available in both direct and indirect models.

Hospitals choose spray foam for temperature control to aid patient recovery
Spray foam insulation can be used in the healthcare sector to help regulate the internal temperature. It is one of the highest performing insulation materials in terms of preventing heat loss when closed cell materials are chosen. A superior insulant retains the heat for longer or prevents warmth from the sun entering the building during spells of hot weather. By controlling the internal temperature at an optimum level this is a key factor in a patient’ s recovery. In the healthcare sector, King’ s College Hospital’ s Critical Care Centre has utilised spray foam insulation below the plant room floor. This compact and versatile insulant could be sprayed from below onto the underside of the irregular shaped corrugated sheeting, providing the required U-value and Class 0 fire rating. The installation was carried out using a British Urethane Foam Contractor Association approved installer.
