TUBE Outside heater for wooden hot tubs- User manual
Page 16/44
Use only small and dry firewood for the heater. The use of big and moist wood will easily
double the heating time. Use of common alder is not recommended, since it causes more
soot and stickier soot than other firewood.
The use of the heater that is loaded from outside of the barrel is as easy as the use of any
other normal fireplace. We recommend the use of small firewood when starting the fire and
then gradually add bigger ones, if needed.
While heating the water, it is advisable to keep up a fair-sized fire
in the heater so that the wood would burn properly and the
maximum output can be achieved. When keeping a small fire the
heating time will be much longer.
Air intakes in the furnace door should be adjusted according to your
needs. When fully open the fire runs well but power might not be
optimal. Please find the best position for your needs.
Cleaning and chemicals
Take care of the sanitation and hygiene of the barrel by washing and drying it often enough.
You can wash the barrel with pine soap and scrubbing brush, or using some other bio soap.
If the barrel is in public use it is important to use chemicals that kill bacteria, in other words
chlorine. When the barrel is only in home use there are oxygen-based alternatives for
chlorine. These chemicals are suitable for disinfecting small tubs. You can find the
instructions for dosages on the packages of the chemicals, and the instructions should be
followed carefully. Over dosages might cause corrosion of the barrel / heater parts. NOTICE!
When using chemicals, it is important to follow the pH level of the water and it should remain
within 7,0 – 7,6. The use of chemicals usually lowers the pH level, which might again result in
corroding the barrel parts. The use of trichlorine-based and other tablet combinations is
prohibited in the barrels, except for 20 g tablets, which do not raise the concentrations too
high. Use only chemicals recommended by the manufacturer.
