To raise the temperature of 1 m3 water in 1 hour by 1°C needs about 1.000 kcal. This formula is only an indication, as the temperature also depends on surface area and any insulation that may be present. All models have been fitted with an adjustable thermostat that can be regulated up to 40?C. The heating element with the temperature probe, as well as the inside of the casing are made of high-quality stainless steel. Profi-Heaters can be connected using pond tubing or PVC tubing. Comes with fittings.
