Turning on energy savings for hot water: instantaneous hot water
Instantaneous hot-water systems can cut energy use and minimise the risk of legionella, says Huw Blackwell, co-author of a new CIBSE guide on reducing DHW temperatures safely in heat networks and buildings
Smart hot water tanks at the heart of the energy transition
Hot water tanks have the potential to store renewable energy, balance the electricity grid, and reduce carbon emissions and utility bills. Alex Smith speaks to Mixergy to find out how the hot water cylinder has the potential to become the smartest technology in the home
Researching new methods for estimating design water flowrate
It is recognised that using the traditional loading units method overestimates the design flow for hot and cold water systems. Heriot-Watt University’s Achala Wickramasinghe explains how the Luna project aims to address the issue and calls for data to help validate a new method
Hotel study reveals predicted hot water use is double the reality
Analysis of two hotels by Elementa Consulting revealed that actual hot-water use is around half of what systems are capable of supplying. Elementa’s David Glossop says this is resulting in much lower carbon savings in new services designs
