The replacement of existing CHP plant at Bedford Hospital includes boilers supplied by Mikrofill. The three Ethos boilers each have an output of 130 kW and will primarily serve the hospital’s HWS demand. They are configured to provide heat into the main system when hot-water requirements are at a minimum.

Condensing boilers have been mandatory in the domestic market for over a decade, but it is only recently that the introduction of the Energy related Products (ErP) Directive has seen the commercial sector follow suit. Pete Mills of Bosch Commercial & Industrial Heating explains what the new requirements will mean for commercial boiler installations.

Riello has introduced low-NOx (less than 80 mg/kWh) ‘blue-flame’ versions to all sizes of its RS range of burners. The use of a low-NOx combustion head ensures emissions conform to EN676 Class 3 in capacities from 3600 to 6260 kW.

Remeha Quinta Pro boilers contributed to a £3000 reduction in gas consumption in just four months at Sandbach School in Cheshire, despite having a greater heat output to meet its present-day requirements. Founded in 1677, it is now a free school with over 1300 students. The new boiler installation comprises six 115 kW boilers in cascade configuration.

The Strathmore Hotel Group, which has hotels in northern England and Scotland, has installed wood pellet boilers to provide heating and hot water for seven hotels. The 36 BioWin Excel boilers from Windhager’s commercial range were installed by Green Guru of Newcastle to replace fossil-fuelled boilers.

ATAG Commercial’s Q Series range of boilers are designed for larger homes, commercial applications and properties with high hot-water demands. They have stainless-steel heat exchanger. There are three combination boilers with outputs of 25, 38 and 51 kW. There are also four system versions with outputs of 25, 38, 51 and 60 kW.

Ideal Commercial Boilers has extended its range of Imax Xtra EL of floor-standing boilers with models offering outputs from 715 to 1240 kW. The range now comprises 10 models with outputs from 320 to 1240 kW. These new boilers expand the flexibility of the range while retaining a compact size that enables them to pass through standard doorways. The range outperforms the 2015 ErP requirements and offers very low NOx Class 6 performance for maximum BREEAM points.

Are you a devotee of wall-hung boilers or is floor-standing more your thing? With today’s boilers offering increased versatility and flexibility in system design, the modern plant room is benefitting from a major makeover. James Porter of Remeha Commercial, looks at the growing options to meet increased heat output demand within the tight constraints of the modern plant room.
