Aquarium heater — Wh honesty
Continuous thermal draw for tropical tanks during outages — the heater is often the Wh killer, not the filter. Distinct from the aquarium backup pump / filter / light stack page (cross-link it). Mid stations can help short storms; multi-day cold rooms need expand packs.
Heater-first honesty — not the filter page
- Continuous / high duty-cycle heat. Submersible heaters commonly nameplate ~50–300 W while on. In a cold room they may stay on most of the hour — that is resistive heat, same Wh physics as a small space heater, just in a glass box.
- Distinct from aquarium-backup. The aquarium backup page sizes pump + heater + light as a stack and prioritizes filtration. This page isolates heater Wh honesty for tropical keepers who already have a pump plan.
- Mid stations help short storms. A ~1 kWh / 1,000–1,800 W class box can often hold a 100–150 W average heater for a few hours through a brief outage (estimates). Overnight in a cold garage is a different math — measure duty cycle.
- Vs humidifier / fridge cousins: cool-mist humidifiers are cheap Wh; fridge compressors cycle — fridge runtime. Heaters that stay on eat Wh like heat, not like a pump.
- Storm / multi-day: pair heater priority with insulation and a filter plan — storm blackout kit · expandable multi-day. Not fish-care advice; confirm livestock needs with an aquatic vet / experienced keeper.

Comparison: aquarium-heater honesty
Filter by whether a station clears continuous / high-duty heater watts for short tropical-tank storms.
| Model | Wh · continuous AC | Heater fit | Vs backup stack / multi-day | Approx. USD |
|---|---|---|---|---|
| EcoFlow RIVER 3 Plus Brief | 286 Wh · 600 W | Clears many heater nameplates; Wh is ~1–3 h at 100–150 W avg (est.). | Pair with pump-priority plan on aquarium backup — not overnight heat alone. | ~$180–300 |
| Anker SOLIX C300 | 288 Wh · 300 W | Similar — continuous W OK for smaller heaters; Wh soft-gates long duty. | Insulate tank / cut drafts before buying more Wh (care judgment is yours). | ~$200–280 |
| Jackery Explorer 1000 v2 Short storm | 1,070 Wh · 1,500 W | Best mid path for a few-hour tropical heater hold (estimates). | Still measure duty — cold rooms can empty this before morning. | ~$499–589 |
| BLUETTI Elite 100 V2 | 1,024 Wh · 1,800 W | Similar ~1 kWh short-storm heater math. | Stack with filter on backup page; storm kit: storm. | ~$380–500 |
| Anker SOLIX C1000 Expand | 1,056 Wh → 2,112 Wh · 1,800 W | Expand packs help multi-hour cold-room heater duty. | See expandable multi-day before promising overnight heat. | ~$400–600 |
| EcoFlow DELTA 3 Plus | 1,024 Wh · 1,800 W class | Solid short-storm heater + light pump extras (estimates). | Not a room space heater budget — tank-scale only. | ~$600–900+ |
| BLUETTI AC200L Best headroom | 2,048 Wh · 2,400 W class | Best Wh in this set for heater-heavy tropical nights. | Still not whole-home heat — compare fridge / humidifier Wh jobs. | ~$800–1,100 |
