If thinking big, the new pumps allow you to positively manage hot water recirculation pipes, and in a full scale trial 16 pumps run 2.4 km of pipes in a large food factory near Peterborough, UK. The pumps reduce heat loss from pipes and reduce the water run to waste.
In central heating, we often have thermostats on radiators to draw off a ring main which is kept constantly hot. However, even when the radiator requires no hot water, the ring main still supplies the hot water. Heat is lost to roof spaces and floors when the radiator needs no hot water. We can avoid this.
Where the central heating ring main or hot water recirculation system
has exceeded its design capacity – let’s say we add an extra wing to a hospital – instead of a new boiler or replacing pipes, just add another pump and because the system is more efficient you may not need a new boiler.
The invention offers many opportunities to improve existing systems and rectify systems that do not work as intended and is a retrofit solution.
