PRODUCTS | SERVICES New Vitocrossal 200 commercial boiler offers maximum output in a compact, easy-to-install package Viessmann has introduced the new Vitocrossal 200 an 800kW-1,000kW gas-condensing boiler, with an innovative MatriX pre-mix disc burner that sets new standards for commercial boilers. The Vitocrossal 200s numerous improvements include: an extended modulation range of 1:6, for greater efficiency at partial load; low-NOx emissions of less than 40mg per kWh; amodular design for easier installation; and significantly smaller dimensions, making it suited to smaller plantrooms. The heat exchanger and burner modules can be separated for easier carriage and individual delivery, while the front cover is hinged on a gas-pressure spring for easy opening. In addition, the side panels can be removed for unobstructed access to the MatriX disc burner. Viessmanns commercial sales director, Jon Grist, said: The new Vitocrossal 200 represents a significant step forward in commercial boilers because of its compactness. Large industrial plantrooms are going out of favour, and being replaced by multiple boiler rooms and the Vitocrossal 200 is perfect for those smaller spaces. This boiler is also desirable for its low NOx emissions, lower minimum output with higher efficiency, and easier handling and serviceability.

More than 7,000m of Kooltherm FM Pipe Insulation has been installed on pipework across the building. The product has an aged thermal conductivity as low as 0.025 W/mK (at 10C mean), making it the most thermally efficient pipe insulation in common use within the UK construction industry.

The location of the kitchens on many floors means gravity drainage is not possible. Very hot water may enter the wastewater system, so Pump Technologys DrainMajor was installed. This system is fitted with a robust Jung Pumpen 730HES pump, which has a cast-iron pump volute and stainless-steel motor housing, combined with a mechanical liquid-facing seal and motor lip-seal configuration.

Zinc-based inhibitors are recommended by Rinnai for use with its appliances. This technology uses electrochemical dispersement to impart a precise amount of soluble zinc. To ensure that limescale is never a problem, Rinnai heaters incorporate a scale-warning device that continually monitors the appliances for limescale deposits around the heat exchanger.

Rinnai proposed three 1500e continuous flow hot-water heating units, cascaded to cope with the high demands. Its Infinity HDC1500i Low NOx boasts the modulation 14:1, 56.6kW to 4.0kW, on both natural gas and LPG gas, and operates at a flow rate of as low as 1.5l/min. The HDC1500e Low NOx is extremely lightweight, at just 31kg.

This combines a sound-optimised fan, designed to harmonise the acoustic frequency range, with intelligent speed control, to reduce airborne noiseat full- and partial-load operation. This effectively stifles the lower-frequency sound of conventional heat pumps, which can be perceived as disturbing. The result is that the pumps are barely audible. They operate so quietly that they are suitable for densely built-up areas, such as terraced housing estates. The energy rating of the new Vitocal heat pumps is A++, and their coefficient of performance (COP) according to the EN 14511standard is up to 5.0 (A7/W35) and up to4.1 (A2/W35). No minimum distance is required between the indoor and outdoor units, no refrigeration leak test is needed because the cooling circuit is hermetically sealed and no F-Gas certificate is required because the connecting pipes to the outdoor unit are filled with water.
