COHEAT @ All Energy 2016
- 1. All Energy – May 5th 2016 Marko Cosic Technical Director marko@coheat.co.uk +44 7774 524 114 Hot data: what can heat metering do for you?
- 3. Why do heat meters tell us? • How much heat was consumed? • What did the network do?
- 4. Sample data
- 5. What does the consumer care about? • Did I get the hot water I wanted? • Did I get the space heating I wanted? • Where has all my money gone? • Is there a fault and when will it be fixed?
- 6. What does the landlord care about? • Is there a fault and when will it be fixed? • Did I provide hot water? • Did I provide space heating? • What should my tariff be?
- 7. What else might a landlord care about? • Is there anybody living here? • Are they alive and well? • Are they looking after my property? • Is there a fault I need to fix?
- 8. What does an operator need to know? • What are/were customers are asking for? • What service are/were we delivering? • What is/was happening in the home? • What is/was the heat network doing?
- 9. A smart heat network
- 10. Heat meters? A smart heat network (prototype)
- 12. Textbook
- 13. Thermal mass
- 14. Absconded
- 15. Room and radiator sensors (prototype hardware)
- 16. Heat meters see problems
- 17. Secondary sensors identify the problem
- 18. Secondary sensors see other problems 18 Towels and underpants House parties
- 19. “I’m cold” 19
- 20. “We’re not ready to let this flat yet” 20
- 21. Heat interface units (prototype hardware)
- 22. Hot water event from heat meter
- 23. Hot water event from secondary sensors
- 24. Real time data for design 24
- 25. Real time data for billing 25
- 26. Real time data for operation 26
- 27. Summary • It’s “Quality of Service” that matters – What are customers asking for? – What are actually you delivering? – How is the network you delivering it? • Don’t have blind faith in heat networks – Heat meters are invaluable – They’re even better in a fully integrated system

Editor's Notes
- Learn how heat meters, smart thermostats, and analysis tools can be combined to improve the efficiency of your heat networks and provide unrivalled insight into the welfare of some of the most vulnerable in our society. COHEAT has been developing an advanced heat network in the West Midlands under DECC's heat network innovation programme. Technical Director Marko Cosic will describe the pilot and how the metering data is used by: Trident Housing Association to ensure that appropriate use of their property portfolio is maintained; Support workers to monitor the comfort and wellbeing of their residents and intervene before fuel poverty and cold, damp conditions become an issue; Residents to know exactly what their bills will be and how the way they use their heating affects energy consumption.
- Heat supply, pipes, heat interface unit. Meters either end of the pipe if you’re lucky.
- Past tense because it’s rare to get real time visibility. Often it’s only once every 30 minutes – so called smart meters – or 5 minutes – because battery powered meters aren’t designed for real time data and they will go flat if they measure too often
- Read the number of the front. This is the historical data you get from a data logger. Engineer can interpret this. Services are available to do this for you. Basically the flatter these are and the lower the return temperature the better. If it were this simple we could all go home now.
- By this: what makes the customer call you. Cold showers. Waiting for taps. Cold rooms. Hot rooms. Confusion and bewilderment because Honeywell. Confusion and bewilderment because laws of physics. You took their money though so it’s your problem. When things do go wrong, which they do, the customer wants to know that you know and when it’ll be fixed.
- Was the water hot enough? Was it too hot? Can I prove this for compliance purposes? Lot of attention Legionella or scalding, particularly in supported housing.

- The every sensor actuator blah blah. You’ve go to meter and bill and have a data connection. Once you’ve done all the hard bits we extend how far we monitor. Smart thermostats are inevitable so you may as well integrate them. Close that loop.
- Trident were bold. They and DECC wanted this sort of thing so badly that let us do anything we want on their site.
