Our castle has a large cellar, which we occasionally rent out or organize there social events by ourselves. Since the cellar is partially built into the rock, the walls are made of stone and the temperature in the place is stable at about 8°C with relatively high humidity. These circumstances considerably limit the usage of our premises.

Before the test of the heating system with DALYN Technology, we used a 15 kW primary heating fan to heat the space. Before the event, we started the heating about 24 hours in advance. Afterwards, the premises were heated to 13-14°C. However, with each door opening there was a considerable leakage of accumulated heat and the overall thermal comfort was not very good.  For the 2022 Christmas party after discussions with NAMI-Tech, we decided to use similar heat-insulated fans for heating in combination with DALYN Technology. NAMI-Tech installed the heating only 6 hours before the event. During this time the temperature of the premises increased from 8°C to approx. 16°C. We also noticed a significantly higher thermal comfort because the walls of the cellar and the mobiliary were also heated. Another noticeable effect was that the accumulated heat was not released by opening of the door.

So, if we compare the original situation: heating approx. 24 hours before the event, input 15 kW, with a consumption of approx. 360 kWh and a price of 8 CZK/kWh, the heating costs were approx. 2,880 CZK. With DALYN Technology: heating approx. 6 hours before the event, power input approx. 16,5 kW, with a consumption of 99 kWh and a price of 8 CZK/kWh, heating costs were approx. 800 CZK.  In conclusion, we can confirm that the costs have been significantly reduced and more importantly, we have found a technology that is able to heat our castle premises and cellars and allow us to use the premises more often. Thanks to that we are negotiating with NAMI-Tech to implement DALYN Technology wherever possible throughout our facilities.
