Small-Scale Smart Heating

In this 2012 piece by Damon Hart-Davis, we explore the concept of smart heating systems that aim to reduce energy consumption and improve comfort in various settings, including homes, schools, and community centers. Key benefits include reduced peak demand, enhanced energy security, and better integration of renewable energy sources. The article highlights current technologies and practices, such as thermostats, measurement tools, and smart controls, showcasing effective use cases and the potential for energy savings through innovative approaches to heating.

Presentation Transcript

  1. What would be 'smart' circa 2012 for our homes, schools, community centres and shops? Damon Hart-Davis 2012/10/30 http://www.earth.org.uk/note-on-smart-heating.html Small-Scale Smart Heating

  2. Why? • Reduction in energy use? • Reduction in peak demand / load shaping? • Improved comfort? • Better use of local and distant renewables? • Energy security?

  3. In Our Toolbox • Avoidance • Thermostats • Clocks • Anticipation • Measurement • Storage

  4. Use Cases and Testable Improvements • Bog-standard home such as mine • School • Community centre • Irregular usage patterns

  5. Extant Controls? • Prefect controls/sensors (UK) • LightwaveRF wireless radiator TRVs and boiler controls (UK) • AlertMe/BG, PassivSystems (integrated, networked: UK) • Nest (US) • Others with good pedigree such as Honeywell • Didn't find: drop-in friendly replacement for normal/setback/frost PIR+timer 2-wire thermostat!

  6. Nest, LightwaveRFWave, Prefect

  7. Research Results • Close The Door: zero technology, up to 50% savings for shops • PassivSystems: savings of 20--40% with mixture of techniques • SSE/Honeywell trial: peak power demand cut up to 36% (non-domestic)

  8. My 'SuperHome' • Super-insulation, draught-proofing, TRVs, careful use of thermostat, clock, MHRV, improved glazing, only lesser 'smarts' in use at the moment:
