Electric Hot Water Auto Booster

The Eemax HATB007240 is an electric hot water auto booster designed for residential indoor use. It operates on a 240V AC single-phase supply and delivers a maximum flow rate of 5 gpm. The unit activates at a minimum flow of .3 gpm and provides adjustable temperature control between 80 and 140 Degrees F.

30 A 240V connection fits standard residential

The booster requires a 30 A current draw at 240V and connects via a 3/4 in female NPT cold inlet. Its compact dimensions of 11.4 in width, 9.7 in height and 3.7 in depth allow installation in tight utility spaces. The adjustable thermostat frees the user from fixed temperature limits while the automatic activation eliminates the need for manual switching.

Replaces undersized tank heaters for point-of-use

This 7240W unit upgrades installations where a central tank cannot meet peak demand or where long pipe runs waste energy. The jump is worth it when instantaneous hot water is needed at a specific fixture without the standby losses of a larger storage system. It is not suited for whole-house high-volume demand exceeding 5 gpm.

Questions about this item

Will the 7240 W element trip a 30 A breaker during continuous use?

The unit draws 30 A at 240 V, so a dedicated 30 A circuit is required and sustained operation will run the breaker at its full rating.

How much noise or heat does the booster produce when running all day?

The booster has no moving parts, so it operates silently; all 7240 W of input becomes water heat, raising the surrounding area temperature only slightly.

What plumbing connections must already be in place for installation?

You need a 3/4 in female NPT cold-water supply line and a matching hot-water outlet, plus a 240 V single-phase electrical feed.
