This project combines many different types of production and
delivery systems. For production, we have installed a solar
hot water, geothermal ground to water, and high efficiency boiler
plants. For delivery systems, we have tied on to an existing
baseboard hot water sytem and domestic hot water sytem. We have
also install a radiant floor heating system.
The system is set into temperature and production priority.
The solar hot water production is used for radiant heating and
domestic hot water if there has been enough production. If not,
the geothermal plant will take over these tasks. When the geothermal
plant cannot recover the domest hot water fast enough, the boiler
plant will start production. The boiler plant will also handle
all hydronic baseboard heating, due the temperatures required
for this type of heating.
This system is controlled by a Direct Digital Control System.
This DDC allows optimization of production and and delivery.
The DDC system is powered by a Circon UHC 300.
