Product Description

This novel reservoir heating system is great for both hydroponic reservoirs or aquaponic fish and sump tanks. 
 
6-7 Kilowatts heating (20-25k BTUs/hr) recommended for systems up to 10,000 gallons. 

How it works

Suspended minerals and solids, when brought into contact with heating elements, will always corrode the elements. Fish Sweaters avoids this problem by indirectly heating the nutrient or fish tank. A small amount of distilled water is continuously circulated between the heater and the tank in a closed loop system using a stainless steel coil.
 
The coil is placed in the tank to be heated. Hot water leaving the heater flows through the heat exchanger coil in the tank. As it does, the water (with suspended minerals and solids) in the tank is warmed and the distilled water in the coil is cooled. After exiting the heat exchanger coil, the cooled distilled water enters the water heater to be heated again. 
 
This process is continuous until the desired temperature is achieved. A waterproof sensor and ruggedized controller are used turn the heater and pump on and off. There is no wasted heat, since only a small amount of water is being heated to affect the temperature change in the tank. Heat transfer is therefore highly efficient, yet the nutrient or fish water is never in direct contact with the heater. 
 

Off Grid Ready

  • Using gas, it can provide 7 KW of heat with less than 30 watts of electricity
  • Powered by low voltage DC
  • Can be run from batteries or PV panels
  • Does not require generator power to maintain heat during power outages

Special Features for Aquaponic Heating

  • Fish and chemical safe 316 stainless steel heat exchanger
  • Continuous heat exchanger coil means no brass or copper fittings in the tank
  • Fits IBC Tote Tanks
  • Side or bottom mounted
  • Controller optimized for fish temperatures rather than domestic hot water
  • Controller electronics are cast in epoxy to prevent corrosion in damp environments

System Includes

  • Fish Sweaters Unique Gas Heater (Natural Gas or Propane) 
  • Annealed stainless steel heat exchanger (28" x 36" coil) with 3 ft. of  connecting pipe
  • Waterproof temperature sensor
  • Ruggedized Temperature Conroller designed for wet environments
  • Mounting Frame for easy installation
Cautions:
 
This unit must be mounted in a well ventilated space. If your greenhouse is fairly tight, you will need to install this in an adjoining space that facilitates enough ventilation.
 
You must also use only distilled water, do not use well or city water with this system it will shorten the product life considerably.
