Eemax HATB007240 Tank Water Heater Booster 7.2 kW 240V
The Eemax HATB007240 is a compact electric booster intended to increase a tank heater’s deliverable hot water by up to 45%. Its zero-clearance design allows installation close to the tank. The digital user interface enables precise adjustments and the stated temperature accuracy ±1°F supports consistent output. External controls provide accessible setpoint changes without accessing internal components.
Best suited for residential sinks, small baths, or to shorten recovery lag on existing tanks, this model emphasizes space-saving installation and precise control. Consider electrical capacity and compatible plumbing layouts when evaluating fit for retrofit projects.
Hatco C-12-208-3-QS Booster Heater 12kW
The Hatco C-12-208-3-QS is positioned as a commercial-grade booster heater with a 12 kW rating for 208V three-phase systems. The unit includes the manufacturer’s one-year parts and labor warranty, reflecting intended use in foodservice, breakrooms, or light commercial applications.

This model requires appropriate three-phase electrical service and professional installation. Its higher capacity suits multiple simultaneous draws or larger sink arrays where a standard single-phase booster would be undersized. Evaluate electrical infrastructure and load calculations prior to selection.
Cash Acme Tank Booster With Mixing Valve 24644
The Cash Acme 24644 is a mechanical tank booster and thermostatic mixing valve assembly designed to temper hot water and help prevent scalding. It blends hot and cold supply to a controlled outlet temperature, factory-set to deliver tempered water at 120°F with the ability to adjust higher if needed.
Installation leverages push-to-connect fittings compatible with PEX, PE-RT, CPVC, and copper lines, reducing the need for soldering or specialized tools. This product serves as a safety-focused booster where tank temperatures are high and point-of-use temperature control is required.
Eemax SPEX95T Lavadvantage Tankless Booster
The Eemax SPEX95T Lavadvantage is a thermostatic tankless inline booster intended for point-of-use fixtures such as kitchen or bar sinks. It features microprocessor temperature control and compression fittings for flexible rear or bottom electrical entry.

Designed to provide near-immediate hot water and then reduce power as the tank’s hot water arrives, it functions as an inline booster or backup to larger systems. The specification cites compatibility with hot or cold feed and high efficiency, making it a compact option to eliminate delays at specific fixtures.
GE Appliances 10 Gallon Plug And Play Water Heater
The GE 10 Gallon plug-and-play unit is a compact electric water heater designed for easy installation into a standard 120V receptacle. It targets applications where a localized hot water source is preferable — kitchens, laundry rooms, cabins, or garages.
Features include standard 3/4-inch NPT water connections, an adjustable thermostat, and a compact footprint for installation where space is limited. Consider this unit when a small-volume storage option is the preferred method to boost hot water availability near a fixture.
Buying Guide: How To Choose An Electric Booster Heater
Selecting an electric booster heater depends on application, electrical capacity, and safety requirements. The guide below outlines main considerations to compare options objectively.
Define The Purpose And Flow Requirements
Determine whether you need a point-of-use inline booster (short delay elimination at a single sink), a tank booster (increase deliverable hot water from an existing tank), or a small storage heater to supply a fixture. Match the device capacity to the expected flow rate in gallons per minute (GPM).
Electrical Supply And Installation Constraints
- Voltage And Phase: Many residential boosters are 240V single-phase; commercial units may require 208V three-phase. Verify available service and breaker capacity.
- Amperage And Wiring: High kW boosters need appropriate wire gauge and dedicated circuits; consult an electrician for load calculations.
- Professional Installation: Commercial 3-phase units or hard-wired 240V heaters typically require licensed installation for code compliance.
Temperature Control And Accuracy
Digital thermostats and microprocessor control offer more precise output temperatures than manual valves. For applications where consistent outlet temperature matters (medical, foodservice, or hair-washing stations), favor models with ±1°F accuracy or thermostatic control.
Safety And Scald Prevention
Where stored tank temperatures are set high for legionella control, use a thermostatic mixing valve or a booster with built-in tempering to prevent scalding. Models like the Cash Acme 24644 focus on output temperature regulation for safe delivery.
Capacity Versus Recovery Versus Booster Type
- Inline Tankless Boosters: Provide immediate heat for small fixtures and reduce wasted water, best for low-flow needs.
- Tank Boosters: Increase the usable hot water volume from an existing tank, useful when demand spikes occasionally.
- Small Storage Heaters: Offer short-term reserve hot water and simpler installation if electrical and plumbing access exist.
Installation Location And Mounting
Consider clearance, accessibility for maintenance, and proximity to the fixture. Compact models (zero-clearance designs) allow installation in tight spaces near tanks or under sinks. Commercial boosters may require ventilated or service-accessible mounting.
Material Compatibility And Plumbing Connections
Check fittings compatibility with PEX, CPVC, copper, or other piping. Push-to-connect fittings speed installation on many tank booster assemblies; compression fittings are common for tankless inline units.
Warranty, Service, And Intended Use
Compare manufacturer warranties and intended use cases. Commercial-rated boosters are specified for frequent heavy use and may include different warranty terms compared with residential devices. Verify local codes for commercial foodservice or public restroom installations.
Energy Efficiency And Operating Costs
Efficiency factors differ by type: tankless inline boosters reduce wait time and water waste, while storage units maintain a reservoir with standby losses. For frequent short draws, inline thermostatic boosters or small point-of-use tanks may reduce overall energy and water consumption.
Comparison Perspectives
- Residential Single Fixture: Inline tankless boosters (Eemax SPEX95T) or compact plug-and-play tanks (GE 10 Gal) are often optimal.
- Increase Tank Deliverability: Dedicated tank boosters (Eemax HATB) can extend usable hot water without replacing the main tank.
- Commercial High Demand: Higher kW three-phase boosters (Hatco C-12-208-3-QS) match multi-fixture or continuous-use environments.
- Safety-First Installations: Use thermostatic mixing valves (Cash Acme 24644) where scald prevention and temperature regulation are critical.
Review electrical compatibility, flow requirements, and safety controls when comparing models. For installations in regulated environments or where major electrical upgrades are needed, consult licensed professionals to ensure performance and compliance.
