Bell Flow Systems is introducing the Axis Industries Qalcosonic range of ultrasonic heat and cooling meters. The Qalcosonic Heat 1 and 2 are MID Class 2 Approved for Domestic Renewable Heat Incentive (RHI) and billing purposes - for use in heating, cooling and hybrid applications. Available in meter sizes from DN15 to DN50, with BSP threaded and flanged connections. Qp values
range from 0.6 to 15 m3/hr, with R100 dynamic range as standard (R250 optional). The use of ultrasonic technology means the meter has no mechanical moving parts, prolonging the life of the meter and ensuring long term flow measurement accuracy. The Heat 1 and 2 cover a wide range of energy metering applications, from residential buildings to larger companies and institutions. The meter benefits from pulse outputs and a range of optional communication modules.

ELCO Heating Solutions has supplied five Thision L Evo 120kW boilers to Westhaven House in Weymouth. The installation was part of the complete refurbishment of the heating and hot water system at the Dorset- based care home, with the aim to reduce energy use, emissions and running costs. This involved the property owners, Aster, removing two ageing atmospheric boilers
and two direct gas-fired water heaters, which had all reached the end of their operating lifecycle and were extremely inefficient to run. They were replaced by a floor mounted cascade system consisting of five Thision L Evo boilers and two 500l Gemini calorifiers from ELCO. In addition, ELCO also supplied a weather compensation kit, while the boilers’ built in control is managing the system pumps and diverter valves for two heating zones and the DHW.

HOVAL
A boiler upgrade at Mylnes Court, University of Edinburgh has seen aging Hoval boilers replaced with the company’s high efficiency SR Plus and UltraGas boilers, specified by Engright Engineering Consultants. Mylnes Court is a complex of buildings that includes three halls of residence. A central boiler house provides space heating, domestic hot
water and pre-heating of ventilation air in air handling units. Engright’s David McNeill said: “The original system was at a later date changed to a low temperature hot water system. As the boilers were still in good condition at the time, they were retained and adjusted to operate with lower flow and return water temperatures. However, as they got older a decision was taken to upgrade them. We selected Hoval boilers again as they offer the required efficiency, and their compact design helped to address space issues in the boiler house.”

FUJITSU
An energy saving Fujitsu Air Conditioning (UK) AirstageTM V-III VRF heat pump system, complete with 12 indoor cassette units, has been installed at Yum-Sa Thai restaurant in Putney. While the products were fitted primarily for their cooling capabilities, they can also provide heating throughout the London venue, which opened its doors to customers in September 2017. The
completed VRF air conditioning system comprised a V-III two-pipe heat condensing unit connected to nine 600mm x 600mm four-way compact cassettes, as well as three 840mm x 840mm four-way ‘slim type’ cassettes. The Fujitsu products were fitted by Essex-based Fan Rescue Ltd, specialists in commercial air conditioning for restaurants and catering venues. The cassettes were painted dark grey to match the interior design, and suspended from its exposed ceiling.

SAV SYSTEMS
SAV’s AirMaster Smart Ventilation Units (SVUs) incorporate key design features to tackle the common problem of draughts from ventilation systems in classrooms, offices and many other workplaces. These include close control of inlet air temperature and exploitation of the Coanda effect to ensure comfortable conditions in the occupied zone. They provide control of
air velocity and incoming air temperature, factors known to create uncomfortable draughts, whilst ensuring effective management of indoor air quality and efficient demand-controlled ventilation. Smart control of inlet temperature by AirMaster SVUs is achieved automatically by using fan differential speed. If the inlet temperature is below the set-point temperature for the space, the inlet fan slows while the exhaust fan speeds up.

NORTEK
Warm air heaters are subject to Lot 21 of the directive and radiant heaters Lot 20. Minimum efficiencies for warm air is now 72% and radiant heaters is now 74%. Crucially, these minimum criteria are applicable for both new installations and when replacing existing products. As a result, customers can be assured that the
heating equipment they are purchasing is highly energy efficient and emissions of harmful environmental pollutants are constrained. Our ErP compliant range includes, PREEVA EC (heating and ventilation unit), which provides combined heating and ventilation with optional cooling. The units are available with a wide range of heat outputs and cooling capacities. The units are available as non- condensing heaters with thermal efficiencies above 91% or fully condensing heaters with thermal efficiencies of 102% (ncv).
