ThermoMate 2.5 Gallon Mini Tank Specifications
Researched from the DOE test procedures, NFPA 54 and NEC code tables, and manufacturer specifications. Updated .
Quick answer
This page collects what is actually published about the ThermoMate 2.5 Gallon Mini Tank and shows what those figures produce, computed rather than transcribed. Anything the listing does not publish is not filled in with an estimate.
Published specifications
Everything here is taken from the listing or the manufacturer, and nothing is inferred.
| Specification | Value |
|---|---|
| Gallons | 2.5 |
| Volts | 120 |
| Listed To | UL |
Published standard Source: Manufacturer listing data. A specification not listed here is one this listing does not publish. Check the installation manual for the full data plate.
Why there is no performance table on this page
This listing does not publish an input rating in BTU per hour or in kilowatts, and without one there is nothing to compute a flow rate or a recovery rate from. Estimating it from the price or from the physical size would produce a confident number with nothing behind it, so this page does not.
The installation manual for this model publishes the input rating on its data plate. Once you have that figure, the recovery rate calculator and the tankless sizing calculator will do the rest.
How it sits against the rest of its category
Other point of use and mini tank heaters in this catalog: ThermoMate ES250B 2.5 Gallon, ThermoMate 4 Gallon Mini Tank, GE 2.5 Gallon Mini Tank, GE 6 Gallon Mini Tank.
Compare them on input rating and on the figures the manufacturer actually publishes rather than on the headline number in the listing title, which in this category is frequently a maximum measured under conditions the listing never states.

GE 2.5 Gallon Mini Tank
$239.00A mini tank from a manufacturer with a parts channel, which matters because the thermostat is the part that fails on these.

- What are the specifications of the ThermoMate 2.5 Gallon Mini Tank?
- The listing publishes gallons, volts, listed to and related figures, shown in full in the table on this page. Anything not shown is something the listing does not publish, and this page does not estimate it.
- Is this page based on hands-on testing?
- No, and we never claim otherwise. Everything here is compiled from the manufacturer listing, published specifications and the energy relations that turn those specifications into flow and recovery figures. We do not test products in person. Where a figure is not published, this page says so rather than estimating it.
- Are the prices on this page current?
- They come from verified catalog data at the time the page was built, and prices in this category move often. Treat any price shown as a guide and check the listing itself before deciding. Availability moves even faster than price does on water heater accessories in particular.
A water heater is a pressure vessel. The temperature and pressure relief valve is the one component on it that is never capped, plugged or removed, and a valve that will not open when you lift the test lever has failed and needs replacing rather than ignoring. If the valve weeps after the heater runs, that is thermal expansion in a closed system and the answer is an expansion tank or a pressure reducing valve, never a cap.
