Cold takes, hot kitchens
Chest Fridge
Chest Fridge Showdown: Save $5 a Year or Save Your Kitchen Space?
TLDR: A chest freezer used as a fridge touts ultra-low energy costs. Commenters are split between efficiency and convenience: some will pay a small ‘convenience tax’ and save floor space, others cite thermal-camera videos and joke about charging appliances rent—turning a niche hack into a climate-and-wallet argument.
An off‑grid tinkerer says the “Nature of Cold Air” hates upright doors—and his chest‑freezer‑turned‑fridge proves it, sipping around 0.1 kWh a day (about $5 a year). He’s so committed he sold conversion kits for decades and now runs two modern chest units with low power and quiet vibes. But the comments? Absolute Cold War.
One camp is melting over convenience: opening a vertical door to see everything is worth a tiny “convenience tax,” as one user put it—about 300 kWh a year (roughly $40). Another points out apartments are tall, not wide: “more vertical space than horizontal,” so a chest box hogging floor space is a non‑starter. A third commenter even did the math on “charging rent” for the square footage a chest fridge eats—petty, hilarious, and so relatable.
Meanwhile, the efficiency crowd is linking receipts, like that viral thermal camera fridge rant showing cold air dumping out of uprights. They love the author’s inverter‑motor brag (gentle starts, battery‑friendly), and some are side‑eyeing the industry’s “stars and awards.” One minimalist just typed “(2009),” roasting the post’s throwback energy. Verdict? The thread is split between save watts and save space, with jokes, math, and a dash of eco‑shame keeping things frosty.
Key Points
- •A converted chest freezer used as a fridge consumed about 0.1 kWh/day and ran ~2 minutes per hour, minimizing temperature fluctuations.
- •The author supplied freezer-to-fridge thermostat kits in Australia for ~20 years and now advises buying chest freezers with built-in +6°C control.
- •Two CHiQ hybrid inverter freezers (142 L and 198 L) set to +6°C consumed ~0.4 kWh/day in a heatwave and ~0.18–0.23 kWh/day on normal summer days.
- •Standby power for the two CHiQ units is about 1.5 W, and their combined startup peak is ~138 W due to inverter-based compressors.
- •Traditional single-phase AC compressors can exceed 1 kW on startup, making inverter-based units more suitable for small off-grid systems.
