Micro-CHP (Flow boiler) project – Sandwell
|LEAD AGENCY:||Sandwell Metropolitan Borough Council|
|PROJECT SUMMARY:||This project will install Organic Rankine Cycle engine technology into fuel poor households in Sandwell BC area. These units are termed Combined Heat and Power (CHP) units and generate both electricity and heat using mains gas. The units are manufactured in the UK by ‘Flow’.
Flow boilers will be offered to ten properties along with programmable thermostatic radiator valves where appropriate. Sandwell will utilise smart technology to monitor relative performance and efficiency of the units.
|EVALUATION METHODOLOGY:||Interviews will be conducted in a sample of households to capture household behaviour, comfort and previous energy expenditure. Interviews will be repeated after a winter heating season with the new technology.
Household interviews will be complemented with thermal data-logging and manual energy meter readings taken periodically by householders.
Heat Meters, Electricity induction clamp current loggers and what hour meters will be used to determine the electricity generated, electricity used in house, and electricity exported (unused) to the grid, along with heat generated by the unit.
The evaluation will consider the cost of fuels for the boiler, the heat output to the domestic heating circuit (measured with heat meters), and any incentives the unit would generate through FIT schemes (had the installation been fitted outside of this funding). Monitoring will be for 12 months, and will include a full winter heating period.
|PROJECT OUTCOMES:||In the past micro-CHP boilers have been considered too expensive for the mass market. This project aims to establish the economics around installing and operating a flow CHP unit in fuel poor homes, as a possible alternative to installing traditional heating systems.|
