The contact I found for a ground source heat pump has experieience of canals: great source of low grade heat.
We could set up a small plant at the end of Merchan't Quay – in the canal turning bay, which is really not used.
We could generate all the heat and power for the Quays -100 kW. At £3,000 per kW year, this will provide an income of 300 million – plus the money for the heat. Carbon 0 power.
The plant will pay for tiself in 2 weeks.
