i have some 165 gallon nutrient reservoirs that need heating. we started out using hydrostore “aquarium” type drop in heaters. ended up having to splice both the element and the thermostat with longer cord to reach the bottom of the tank and sealing up the splices inside 3/4" tubing with silicone. it worked. but as with all hydrostore products they seem to die every 4 months.
does anyone have experience with a hot water heater element?
any other ideas?
i’d rather not build a room around my exposed reservoirs. they are inside the building but not in a heated area.
thanks in advance for your input.
