Hot tap water installation for high-rise building in Rotterdam

The challenge

The Pyramide student and starter high rise apartment is owned by Woonstad housing corporation in Rotterdam. The hot water for all 109 apartments is made with a gas-fired loading boiler and a ring line along the apartments. There were solar collectors on the roof to support the making of hot tap water, which unfortunately no longer functioned. The housing corporation wanted a more effective solution with more operating hours to replace the traditional solar collectors.

The solution

We have made a plan with 24 PVT heat pump panels of 2 m2 as a source for a 12 kW modulating Nibe heat pump. The installation has been running for a year and has been running continuously for the first 12 months (more than 8000 hours). This has resulted in a saving of 9200 m3 of gas, 18 tons of CO2 and 7,500 kWh of electricity per year.[ultimate_carousel slides_on_desk=”2″ slides_on_tabs=”1″ slides_on_mob=”1″ el_class=”carousel-fontsize” next_icon=”ultsl-arrow-right6″ prev_icon=”ultsl-arrow-left6″][/ultimate_carousel]
