EDITOR’S COMMENT & CONTENTS


Turning waste water in energy savings A


t a time when businesses are feeling the pinch of rising energy bills it’s worth considering alternative ways of reducing


energy demand, and one solution which is frequently overlooked is waste water heat recovery (WWHR). This is particularly relevant for buildings


where showers are extensively in use such as hotels, gyms, spas, leisure centres, or student accommodation.


It’s true many businesses are focused on decarbonisation but often the thinking is to achieve this through the installation of heat pumps or solar panels. However, before investing in new ways to generate heat, it may well be worth thinking about how to reduce the amount of energy their building needs. This is the message

from building services technology specialist Showersave this month.


The company offers a passive technology that


captures heat energy from water heated by the buildings water heating system.


In most cases this water would then would simply be left to run down the drain, but Showersave argues this is energy that not only could but should be reused. Head over to pg 7 to learn more about this potentially beneficial opportunity for businesses to soften the blow of crippling energy bills. Other features this month include The Heat &


Energy Briefing; Low Carbon Solutions; Domestic & Commercial Heating; Lighting & Lighting Controls; and Pipes, Valves & Fittings.
