The objective of project was to heat the water for the 5 outdoor bath tubs with solar thermal energy in the summer and with wood in the winter.

The main units:

  • Windhager LOGwin woodboiler with 3 pcs of 500 litres buffers (existing)
  • Heat exchanger to heat domestic hot water from the buffers (existing)
  • 1000 litres outdoor thermos for the tubs
  • Hot water cylinder with one coil 500 litres
  • Solar thermal panels 18 pcs
  • Bath tubs made of wood 4pcs with 500 litres capacity each
  • Bath tub 1pc with 1500 litres capacity
  • Space heating system with radiators (existing)

After the first test period it became clear, that depending on the wheather we have some surplus solar energy what causes overheating problems and what we could use for space heating. This is why another heat exchanger has been added to the system with the necessary controls to make it possible to heat the buffers with the solar panels.
Additionally a Windhager VestoWIN stove has also been installed for cooking purposes in the kitchen which also heats the buffers.
