Doesn’t burning wood have a negative influence on the environment?
It is better to burn wood (especially well dried wood) rather than to use resources such as oil or gas. The CO2 that is released when burning a wood fire has a short cycle. Resources such as oil and gas have a long CO2-cylce. When burning well dried wood the smoke is 100% degradable; trees use these fumes to produce Oxygen. This way wood is an environmentally friendly resource.
What is the right temperature for a hottub?
In general an ideal bathing temperature is between 38 and 40ºC. However there are people who prefer a colder or warmer bath. Please be aware that a bath over 40ºC can be dangerous. The human body needs to be able to lose some of its heat. That is why good hot tubs have seats at various levels. If your body gets to warm, dizziness may occur.
My Størvatt pool heater seems to leak?
All Størvatt pool heaters are tested before delivery. What seems like leaking is probably condensation. By intensifying the fire, the condensation will disappear.
