GE 40 Gallon Lowboy 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 GE 40 Gallon Lowboy 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 | 40 |
| Fuel | Electric resistance |
| Element W | 5500 |
| Elements | 2 |
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.
Recovery and first hour rating
Computed from the published input rating with the energy relation, so these figures cannot disagree with the calculators on this site.
| Temperature rise | Recovery | Estimated first hour rating |
|---|---|---|
| 60 F | 37.5 GPH | 66 gal |
| 70 F | 32.2 GPH | 60 gal |
| 80 F | 28.2 GPH | 56 gal |
| 90 F | 25 GPH | 53 gal |
| 100 F | 22.5 GPH | 51 gal |
Convention Source: Recovery computed from the published rating, first hour rating estimated with the 70 percent usable storage convention. The measured DOE first hour rating on the EnergyGuide label governs over this estimate.
How it sits against the rest of its category
Other electric storage tanks in this catalog: GE 30 Gallon Electric, GE Smart 40 Gallon Short, GE Smart 40 Gallon Short, 12 Year, Bradford White RE340T6 40 Gallon.
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.
Other electric storage tanks
GE 30 Gallon Electric
$576.00Thirty gallons suits one or two people. Going smaller than the household needs is the cheapest mistake to make and the most annoying to live with.
Best for: One or two people, or an apartment
Check price on Amazon
GE Smart 40 Gallon Short
$621.00A ten year warranty usually means a thicker anode rod rather than a better tank, and the anode is a part you can replace yourself for about thirty dollars.
Best for: A short-height 40 gallon slot

GE Smart 40 Gallon Short, 12 Year
$675.00The twelve year version of the same tank. Compare the price difference against the cost of one anode rod before paying for it.
Best for: Hard water areas where the anode does real work

- What are the specifications of the GE 40 Gallon Lowboy?
- The listing publishes gallons, fuel, element w, elements 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.
