As an Amazon Associate we earn from qualifying purchases. Links on this page are affiliate links.
You might be considering eemax eem24036 electric tankless water heater alternatives because your specific needs differ from what this unit offers. The Eemax EEM24036 delivers 36 kW of power in a compact 21 by 17.5 by 3.75-inch frame. It uses self-modulating technology to adjust energy input based on demand. This makes it ideal for tight spaces where endless hot water is a priority. However, its narrow profile and lack of smart features may not suit every home.
You might prefer a different size, a digital interface, or app connectivity. Some installations require more robust electrical infrastructure than the Eemax provides. Others need precise temperature control or a wider unit for easier maintenance. We selected these options because their specifications overlap with the original. Each alternative shares the 36 kW heating capacity but varies in dimensions, voltage requirements, and control features. This list helps you find a match that fits your electrical setup and spatial constraints without sacrificing performance.
Our top pick: Eemax 36 kW Compact Tankless Water Heater.
How Each Alternative Compares
Stiebel Eltron Tempra 36 Trend Tankless Water Heater

The Atmor AT-36N-XTP provides 36 kW power with a high flow rate of 7.03 GPM. It is very narrow at 4.49 inches wide but taller at 14.3 inches. Weighing 18.2 pounds, it is lighter than the Eemax. It offers precise temperature control for homes with robust electrical setups. Choose this if you value durability and exact temperature settings over extended warranty coverage. The main difference is the narrow profile and high flow capacity, which suits users prioritizing performance and precision in a compact width.
Rheem 36 kW Electric Tankless Water Heater
The Rheem RTEX-36 offers 36 kW heating on 240V power, similar to the Eemax. It weighs 24.4 pounds and lacks smart features or digital displays. This model suits buyers who value simple, adjustable electric heating. Pick this if you want a straightforward unit without app connectivity or complex controls.

Frequently asked questions
Are all these alternatives 36 kW units like the Eemax EEM24036?
Yes. Every listed option provides 36 kW of heating power. This ensures they can deliver similar flow rates for multiple fixtures. You will need adequate 240V electrical infrastructure for any of these models. The power output remains consistent across brands, though physical dimensions vary significantly.
Which model is the most compact for tight spaces?
The Stiebel Eltron Tempra 36 Trend is the narrowest at 16.6 inches wide. It stands 14.5 inches tall and weighs only 19 pounds. The VEVOR model is also slim, measuring 13.7 inches square with a thin 5.31-inch depth. These dimensions suit small utility closets or under-sink installs.
Do any of these heaters offer WiFi or app control?
Two WINTEMP models include WiFi features for remote monitoring. The WINTEMP WN36 and WM36V allow you to adjust settings via an app. The Eemax, Stiebel Eltron, VEVOR, Atmor, and Rheem units do not list smart connectivity. They rely on physical dials or digital touchscreens for local control.
Which unit has the highest water flow rate?
The Atmor AT-36N-XTP specifies a flow rate of 7.03 GPM. This is the only model explicitly stating its gallons-per-minute output in the data. Other units imply high flow through their 36 kW power rating, but Atmor provides the precise metric for your hot water demand.
Is there a difference in weight between these 36 kW heaters?
Yes, weights range from 18.2 to 38 pounds. The Atmor is lightest at 18.2 pounds, while the WINTEMP WM36V is heaviest at 38 pounds. Most others fall between 19 and 36 pounds. Heavier units often indicate denser internal components, such as copper cores or thicker metal casings.
Which model uses a copper heating core?
The Stiebel Eltron Tempra 36 Trend features a copper core. This material choice supports durability and efficient heat transfer. The other listed models, including the Eemax and WINTEMP variants, do not specify their core material in the provided data. They use standard electric heating elements.
Can I use these heaters in homes with limited electrical capacity?
No. All listed units require 36 kW of power. This demands robust 240V electrical infrastructure, often involving multiple circuit breakers. WINTEMP explicitly notes a four-breaker requirement for some models. You must verify your home’s electrical panel can handle this load before installing any of these alternatives.
