FEATURE BOILERS, PUMPS & VALVES GUIDE TO IDENTIFYING BOILERHOUSE
EFFICIENCY LAUNCHED With economic uncertainty dampening the abilities of businesses to compete in a domestic and global market, energy, maintenance and plant operators are under increasing pressure to reduce operational costs. A new guide from Spirax Sarco sheds light on the core challenges with traditional boilerhouse energy measurement and areas for improvement
A
uthored by Darren Silverthorn, national controls and metering
specialist at Spirax Sarco, the new guide aims to support operational management teams by highlighting areas for improvement that could be made to enhance efficiency and reduce the money spent paying for energy. A guide to identifying the true efficiency of
your boilerhouse identifies several issues with traditional boilerhouse energy measurement, including using burner efficiency to indicate the overall efficiency of the boilerhouse. Additionally, it highlights eight potential areas for improvement that managers could be missing out on, resulting in a potentially unoptimised system, higher operating costs, increased fuel consumption and carbon emissions. The guide highlights the benefits of using a cost-effective, innovative
solution to safely and efficiently get a full overview of the performance of the steam system, such as a boilerhouse energy monitor. There is often limited means of energy
monitoring in most boilerhouses and therefore limited knowledge of overall boilerhouse performance, with facilities often unaware of where energy losses could be identified. A boilerhouse energy monitor provides a compact solution to gather that all important data – helping facilities managers to help themselves. “UK businesses have suffered from
weakened competitiveness owing to rising energy costs and an uncertain economic environment,” says Silverthorn. “These businesses could reduce their operational costs by monitoring the energy performance of their boilerhouse, to understand the losses the steam system could be experiencing.
“This guide aims to help energy,
maintenance and plant operators to help themselves by providing them with the areas they could improve upon to boost boilerhouse efficiency, reduce operating costs and make tomorrow a more efficient, cost-effective day.” The guide can be downloaded from the Spirax Sarco website.

Croydon Council responds to climate emergency
A Croydon Council pilot scheme with Kensa Contracting is installing a low carbon ground source heat pump system that will cut the cost to residents and the environment
T
he ground source heat pumps at the council-owned 10-storey block in
New Addington will cut carbon emissions, help improve air quality, and save up to £300 per home per year on more than 40 households’ heating bills. The project comes after Croydon
Council declared a climate emergency this summer, and aims to contribute towards a local target of cutting the borough’s carbon emissions by 34 per cent by 2025. Kensa Contracting will be undertaking
the ground source heat pump installations, following on from a tower block retrofit scheme in Enfield. The 44 flats are the first in Croydon to
have ground source heat pumps retrofitted, replacing the existing electric storage heaters. An individual Kensa

Shoebox ground source heat pump will be installed in each flat, connected to an ambient shared ground loop array. The ambient nature of the heating
distribution system will prevent overheating of communal areas, whilst the individual heat pump in each flat will provide the tenant with independent control and the freedom to switch fuel suppliers for the cheapest energy tariff. As well as saving each home between
£260 and £300 a year off their bills, the ground source heat pumps will cost less for the council to maintain than storage heaters. The replacement of the tower block's
electric storage heaters with Kensa’s ground source heat pump system cuts lifetime carbon emissions by the equivalent of a 242,317-mile car journey;
or driving around the world ten times. The average night storage heater produces approximately 2,001kg of carbon dioxide per year, compared to the new ground source heat pump system that produces around 645kg per year. Kensa expects to complete the works
by spring 2020, timed to coincide with an 18 month, £3.2m refurbishment to the block including new insulation, a replacement roof and windows, landscaping and new parking. The £700,000 heating system will be
funded through the council’s ring-fenced housing budget and via energy credits from energy regulator, Ofgem.
