Undersink electric tankless heater

The Eemax SPEX55T is an electric tankless water heater designed for undersink installation in residential and commercial settings. It operates on 240V AC single-phase power and activates at a minimum flow of 0.2 gpm. The unit delivers hot water on demand without a storage tank.

Cold inlet and flow limits

The 3/8 in cold inlet size determines the plumbing connection required for installation. A maximum flow rate of 3 gpm defines the peak hot water volume the heater can supply. The minimum flow activation of 0.2 gpm means very low-demand fixtures may not trigger the unit.

5500 watt power consumption

The heater draws 5500 W at 23 A, which dictates the circuit breaker and wire gauge needed for safe operation. This single specification decides whether the existing electrical service can support the unit without upgrades. Buyers without a dedicated 240V circuit rated for this load cannot use the heater.

Questions about this item

Does the 3/8 in cold inlet on the SPEX55T require periodic descaling or filter changes?

The unit has a 3/8 in cold inlet and activates at 0.2 gpm; mineral buildup can restrict that flow, so descale annually in hard-water areas to keep the minimum activation working.

What limits continuous output when the SPEX55T runs at its 5,500 W rating?

At 5,500 W and 240 V the heater draws 23 A; the circuit breaker and wiring capacity are the first limits during sustained use.

How much waste heat and noise does the SPEX55T produce during all-day operation?

The 5,500 W element releases nearly all its energy into the water, so the compact 10.75 × 5.25 × 3 in cabinet stays cool and silent with no fan or moving parts.
