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.
Original concept of the customer
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.
We started working with with solar thermal energy in 2006 and with biomass even earlier. Having successfully installed systems in Hungary, Romania, Croatia, Slovakia we have gained valuable experience across Eastern Europe We continually strive to make systems less expensive, more reliable and more cost effective.
