Why Is This Product On Rise?

The Stiebel Eltron Mini 2.5-1 tankless water heater is designed for installation at the point-of-use, or under the sink. 120V - 2.4kW Mechanical

The Mini heats water instantaneously as it flows through the unit. Stand-by heat-losses are completely eliminated. The efficient heating elements are controlled by a simple flow switch. Additionally, all Mini water heaters are equipped with a safety high-limit with a manual reset.

Flow controls and faucet aerators are highly recommended in conjunction with tankless water heaters. The Mini 2-1 is internally restricted to 0.32 GPM. The Mini 2-1, 2.5-1 and 3-1 models ship with a 0.5 GPM pressure compensating flow reducer / aerator. All aerators are designed to fit the most common faucets. No pressure relief valve, drains, or circulating pumps are needed.

1 Nominal mains voltage is 110–120 V and 220–240 V. 

2 This is our recommendation for overcurrent protection sized at 100% of load. Check local codes for compliance if necessary. Tankless water heaters are considered a non-continuous load. 

3 Copper must be used. Conductors should be sized to maintain a voltage drop of less than 3% under load. 

4 Mechanical units suitable for supply with cold water only. Thermostatic units can accept inlet water of 122 °F.
