2500L and 2 x 10Kwatt heat pumps



Hot water consumption is measured by Wi-Fi smart meters and each owner or tenant is billed individually.


Commercial hot water solution with 3 x 20000L and 6 x 100kW heat pumps


Our technology:

  • All our tanks are hand build
  • Up to 2500L sizes are fully assembled at out factory
  • All tanks ranging from 3000L up to 25 000L are assembled on site as below images show
  • We can only need access through a single standard door to bring in our units and component parts










How does it work?

  • The heat accumulator tank has a zero pressure rating,
  • Which means that the fiberglass tank is in essence a pot of water that is being energized up to 60 degrees by means of the heat pump.
  • The fresh water which is fed into the heat exchange coil is under municipal pressure,
  • As the cold municipal water coils up inside the tank, it absorbs the latent heat from the water in the tank,
  • By the time it reached the top, it has reached 60+ degrees Celsius.
  • Our tanks are perfectly insulated, and has therefore a zero standing heat loss. By doing this, we increase the energy efficiency by at least a further 10%.
  • A combination of solar heat collector panels, heat pumps and heat recovery is used which has an energy saving of more than 60%, and with our tank combination, we have reached savings as high as 70%.


Off-site monitoring:

We created an off-site monitoring system, that allows us to view the entire plant operation, and this gives us early warning system in case something goes wrong. We installed the system at Airchefs in Kempton Park, and we can have a technician on site, even before the client realizes they have a hot water problem.
