Taking the blended approach: all electric low carbon hot water


A


ir source heat pumps (ASHP) are a technology that operates most effi ciently at lower temperatures, making them highly applicable to domestic applications, but domestic hot water (DHW) systems for commercial properties require a 60°C working fl ow for safe operation and anti-legionella processes.


This does not prevent the use of ASHPs as they can be pushed to deliver a higher percentage contribution, generating working temperatures of 45-50°C for preheat, but this requires electrical energy, and that has operating cost implications. However, when compared to an equivalent-sized direct-electric (i.e., from the grid) system, one with an ASHP can achieve carbon reductions of 42-47%, whilst saving 25-35% of the energy costs.


The simplest approach blends preheat, such as from an Adveco FPi32 ASHP with, for example, the Adveco ARDENT 9-100 kW electric boiler to supply thermal energy to a mains water-fed compact indirect cylinder. Balancing such a hybrid electric system is key to ensuring effi cient operation, so consideration needs to be given to controls to assure the water heating remains consistent, and that the two technologies do not fi ght each other.


Working in a balanced combination, enables systems to be sized down, by as much as half in terms of ASHP requirements. This delivers immediate capital savings as electric boilers are far less expensive compared to an equivalent heat pump.

Nuaire’s signifi cant hire to bolster fan fi re safety expertise


N


uaire has hired leading fi re safety expert, Simon Plummer, in a bid to cement its position in the fi re and smoke extract market.


As active members of the Smoke Control Association


(SCA), Nuaire is seeking to reinforce its position in the fi re and smoke market, amplifying its quality of service, technical knowledge and experience, which it has held for over 60 years.


Mr Plummer, divisional manager UK Axials at Nuaire, and member of the SCA said: “Nuaire prides itself on its high standards, superior expertise, and quality assurance. As a manufacturer it has a long-established heritage in the production of world-class axial fans, and it is my pleasure to join the team and help cement its position in the fi re safety sector. Nuaire has launched the AXUS Smoke Shaft System, AxTân. The AxTân has been overseen and developed with Mr Plummer, and is said to be the ONLY fully-certifi ed shaft system - an all-in-one solution with skid, cowl and fan combined. This means it can be delivered straight to site and fi tted as one whole unit, thus reducing time spent assembling on site as well as mitigating any installation issues.


AxTân hits a sweet spot in performance of 6m3/s and 300pa. Its high effi ciency motors result in lower running costs, making it the optimum choice for any specifi cation.
