EcoSmart Pool Heater Specs — BTU Ratings & Efficiency Table
EcoSmart pool heater datasheet summary: model-by-model BTU ratings, efficiency and COP from official sources, linked line by line — with sizing context against the industry formula.
Quick answer
EcoSmart's published heater lineup covers 1 models across 1 product line (electric resistance), spanning 61,000 BTU/hr. Electric resistance models deliver essentially all rated power as heat. Check any model against your pool's requirement with the BTU calculator.

EcoSmart keeps the lineup focused on a single fuel path rather than spreading across every category — the table below is short enough to compare against your required BTU in one read.
Every figure below traces to an official EcoSmart source (linked per table); anything the sources don't state is marked "(to be verified)" rather than guessed. To see whether a given BTU rating fits your pool, run the BTU calculator first.
EcoSmart SMART POOL (Electric resistance)
Tankless electric resistance heaters — no flue loss, but every BTU bills at kWh rates; realistic for small pools, spas or as a booster.
| Model | Rated BTU/hr | Efficiency / COP | Notes |
|---|---|---|---|
| SMART POOL 18 | 61,000 output | (to be verified) | 18 kW at 240V (≈61,000 BTU/hr = 18 kW × 3,412 BTU/kWh), 2×40 A breakers, ~3.5 GPM at working pressure; brand positions it for pools to ~10,000 gallons or as a booster heater. |
How to read these specs against your pool
Electric resistance models have no flue loss — essentially 100% of the rated power becomes water heat — but every one of those BTU is billed at electricity rates, which is why resistance heat suits small pools, spas and booster duty rather than whole-season heating. The running cost calculator makes the comparison concrete at your kWh price.
Three practical checks before buying: first, confirm the required capacity with the BTU calculator (wind, shade and a solar cover move it); second, match the rating type — don't compare a gas input figure against a heat pump output figure; third, verify the exact model against the official EcoSmart datasheet and your installer's gas-line or electrical assessment, because installation constraints, not the spec table, decide what can actually be connected.
Then estimate what the model costs to run in the running cost calculator. This page is independent — no affiliation with EcoSmart; brand names are trademarks of their owners.
FAQ
Where do these EcoSmart specifications come from?
Every figure is captured from EcoSmart's own published material — official product pages, datasheets and installation manuals — with the source link shown under each table and a capture date. Nothing on this page comes from retailer listings or third-party claims about EcoSmart products.
Why do some fields say "(to be verified)"?
When EcoSmart doesn't publish a number for a field (a COP value, for example), this page leaves it marked "(to be verified)" instead of estimating it. The missing figure changes nothing about the ratings that are published — and the BTU calculator works from capacity, which every model states.
How do I compare EcoSmart with another brand?
Compare the same rating type: input BTU/hr against input, output against output, and convert gas input to delivered heat at the stated efficiency. All brand pages on this site follow the same table format from the same capture discipline, so brand pages are directly comparable — that is the point of running them on one neutral site.
