[How2] Poolheizung

Because the pool wasn't going to be a problem despite the moderate outside temperatures, a pool heater was needed. The heated pool had a diameter of just under 4 meters and a volume of about 6 cubic meters. From an outside temperature of 17 degrees Celsius and a water temperature of just under 10 degrees Celsius, it took about eight hours to heat the water to 30 degrees Celsius. One liter of water was pumped through the heater in nine seconds and came out at an average temperature of 45 degrees Celsius. In truly hellish heat, it even briefly reached 50 degrees Celsius, but that meant the wood consumption was a bit high.
