URBAN RIGGER
“Hydro source heating”

An efficient, economical, and above all – environmental responsible and sustainable solution!

As URBAN RIGGER is a floating dwelling, it seemed natural to utilize the surrounding water as a free and clean heating source, utilizing the latest technology from our global partners.

URBAN RIGGER “Hydro source heating”
Using the Seawater as a natural source of heat, is not only clever, but has a number of exiting advantages:

  • The heat transfer rate from water is higher than using the ground as a heat source.
  • The water is in close contact with the entire pipe at all times enhancing its efficiency.
  • The flow/circulation of water provides constant energy replacement.
  • The return temperature to the heat pump is generally 5-6°C higher than ground collectors, increasing the efficiency of the Danfoss heat pump in the URBAN RIGGER.

A cold-water anti-freeze mix is pumped through a series of energy absorbing non-corrosive hydro pex pipes in the base slab of the hull on URBAN RIGGER. As heat naturally flows from warmer to cooler places, the anti-freeze mix circulating around the array is constantly warmed by the sea’s low-grade heat.

During summer months, harbor water hovers around 18-21 degrees Celsius, and the URBAN RIGGER facility sends heated water through 800 meters of hydro pex-pipes to the apartments, where the off-grid-connected 5 kWh-capacity Danfoss heat pump , boost temperatures to between 40-55 degrees Celsius for heating and warm water through the system for floor heating and utility water.

In winter months, when seawater temperatures dip as low as 2 degrees Celsius, the heat exchanger boosts water temperatures up to 70 degrees Celsius, witch is the perfect level water temperature each apartment requires for comfort and enjoyable living in the winter months.

An Efficient, Economical, and above all, an Environmental responsible and sustainable Solution.  The Danfoss 5 KW heat pump combined with a 7,5 Kwh Hanwha Q-Cells PV panel solution on the URBAN RIGGER roof, charging the dual 3,5 KW Lit-Ion battery banks, creates the sustainable and cost-effective heating source needed, generating a whopping 17,5 kilowatt-hours (kWh) of heat from just 1kWh of electricity, reducing the coefficient of performance for the heat pump, while reducing emissions by 81% compared to conventional heating using natural gas, grid or oil as a power source.
