Heat pumps extract warmth from ice cold water
The BBC reported how in Norway a county capital in Norway, 40 miles from Oslo, is extracting heat from the local fjord.
With average annual temperatures of 8 degrees, Drammen has installed a district heating system to meet the heating demands of not only the 65,000 residents, but also the businesses as well, with the brains behind the scheme coming from Glasgow.
“Water source heat pumps hold a number of key advantages… they cost a lot less than ground pumps because no digging is involved, and as water maintains its temperature much better, they offer more consistent performance than air pumps.”
The system has already paid for itself since being installed back in 2011, saving around €2 million per year and 1.5 million tonnes of carbon – equivalent of taking 300,000 cars off the road.
For a river such as the Thames, it is believed that 1.25GW of heat could be produced to supply 500,000 homes.
Certainly something that with collaborative action could result in cheaper heating for all in many UK towns and cities around the country due to numerous waterways.
