# hygger HG273-150W Aquarium Heater, 150W

The hygger HG273-150W is a 150W submersible aquarium heater listed for 75–115L tanks, with temperature displays on both the heater and controller. Its digital readout and retained settings make temperature checks and restoring a preferred setting simpler, while the listing’s water-capacity claims are inconsistent and worth confirming for your tank.

- The controller can show the saved setting when SET is pressed. The display indicates current temperature steadily after setting.
- The listing claims settings are retained after power returns and heating stops when the set temperature is reached.
- Automatic shut-off is claimed for contact with air, low-water operation and a displayed 97°F \(36°C\) threshold.
- The manufacturer describes the heating tube as insulated quartz and says the heater is suitable for freshwater and saltwater.

## Pros

## Before you buy

- The listing gives 75-115L for this 150W model, but also says this heater range suits tanks from 7.5-302L and separately describes a 7.5-302L range across multiple specifications. These capacity claims are inconsistent. Confirm the intended range for the selected model before buying. The listing does not provide a full adjustable temperature range.

## A good fit for

- Aquarium owners seeking a 150W submersible heater for a tank they have confirmed is within the applicable capacity range.
- Buyers who want temperature readings on both the heater and its controller, plus power-restoration setting memory.

## Less suited to

- Buyers who need a clearly specified adjustable temperature range before choosing a heater.
- Anyone unable to keep the heater fully submerged with adequate water circulation.

## Customer feedback

There is no customer-review summary or aspect-level feedback supplied. Aggregate ratings show a mixed picture, with ratings concentrated at the top end but also at the lowest star level. With only a small rating sample, this does not establish reliability or explain customer experiences. For a heater where the applicable tank-capacity range is unclear, verify the model-specific fit rather than relying on ratings alone.

## Frequently asked questions

### What tank size is this heater intended for?
The title lists 75-115L, but other listing copy describes a much broader 7.5-302L range across multiple heater specifications. Confirm the capacity for the selected 150W model before purchase.
### Does it have a temperature display on the controller?
Yes. The listing describes LED digital displays on both the heater and controller, with matching readings and indicator lights.
### Can it operate partly out of water?
No. The supplied instructions say it must be fully submerged during operation and used with adequate water flow and circulation.
### What happens after a power interruption?
The listing claims the heater retains its previous settings when power is restored.
