The Ecco stove can be used for domestic hot water (DHW) through the use of the hot box. Due to the nature if the silicon carbide the amount of heat transferred will be less than a conventional boiler stove and will take longer to re-coup the water used.

Therefore we suggest using the hot box in conjunction with a secondary system such as an immersion heater to support in order to provide adequate hot water. The amount of water provided is 2 x 30 gallon cylinders to 842⁰F in 24 hours provided the Ecco stove® is run to optimum 392⁰F for 15 hours in 24.
