Smeg FAB38RRDAU Energy Cost: Is It High?

Yes, the Smeg FAB38RRDAU has a relatively high energy cost compared to modern, similarly sized refrigerators, but it is not the most inefficient fridge on the market. This 519-liter retro-style fridge-freezer typically consumes around 400–450 kWh per year, which can cost roughly $100–$150 annually depending on your electricity rate. Below, we break down the actual energy usage, running costs, and how it compares to more efficient alternatives.

Background: The Smeg FAB38RRDAU

The Smeg FAB38RRDAU is part of Smeg’s iconic ‘FAB’ line, known for its 1950s-inspired rounded design and vibrant colors. This particular model is a large American-style fridge-freezer with a total capacity of 519 liters (about 18.3 cubic feet). It features a bottom freezer drawer, adjustable glass shelves, and a retro aesthetic that many buyers find irresistible. However, its vintage look comes with a modern trade-off: energy efficiency.

When it was introduced, the FAB38RRDAU received an energy rating of F on the EU energy label (which ranges from A to G, with A being most efficient). This places it in the lower tier of efficiency, though not the worst. In Australia, where the ‘AU’ suffix indicates the model is sold, it carries a similar energy rating. The unit uses a standard compressor cooling system (not inverter technology), which is less efficient than newer variable-speed compressors found in many modern fridges.

How Refrigerator Energy Consumption Is Measured

Refrigerator energy use is typically measured in kilowatt-hours (kWh) per year, based on standardized testing that simulates normal household use. The test assumes an ambient room temperature of about 25°C (77°F), with the fridge set to 5°C (41°F) and the freezer at -18°C (0°F). Actual consumption can vary significantly based on room temperature, how often the door is opened, and the amount of food stored.

For the FAB38RRDAU, the official annual energy consumption is listed as approximately 421 kWh/year (though some sources cite up to 448 kWh/year depending on the region and testing standard). To convert this to a daily figure: 421 kWh ÷ 365 days ≈ 1.15 kWh per day. That’s roughly the same as running a 100-watt light bulb for 11.5 hours.

Calculating the Annual Running Cost

To estimate the cost, multiply the annual kWh by your electricity rate (in dollars per kWh). Here’s a simple formula:

Annual cost = Annual kWh × Electricity rate ($/kWh)

Using the default values from our calculator (421 kWh/year and a rate of $0.30/kWh, which is a common average in the U.S. and Australia):

421 × 0.30 = $126.30 per year

That’s about $10.50 per month. If your rate is lower (e.g., $0.15/kWh), the cost drops to $63.15/year. If it’s higher (e.g., $0.40/kWh), it jumps to $168.40/year. To get a precise figure for your situation, use the calculator below.

Formula

The formula is straightforward:

Annual Cost ($) = Annual Energy Consumption (kWh) × Electricity Rate ($/kWh)

Where:

• Annual Energy Consumption is the kWh used by the fridge in one year (from the energy label or manual).
• Electricity Rate is what you pay per kilowatt-hour, found on your utility bill.

For a monthly figure, simply divide the annual cost by 12.

Worked Example

Using the defaults from the calculator:

1. Annual energy use = 421 kWh
2. Electricity rate = $0.30/kWh
3. Annual cost = 421 × 0.30 = $126.30
4. Monthly cost = $126.30 ÷ 12 = $10.53

So, with these inputs, the Smeg FAB38RRDAU would cost about $126.30 per year to run, or $10.53 per month.

How It Compares to Other Fridges

To put this in context, let’s compare the FAB38RRDAU to other common fridge types:

• Modern French-door fridge (600L, A+++ rated): ~200–250 kWh/year → $60–$75/year at $0.30/kWh
• Standard top-mount fridge (400L, A+ rated): ~300–350 kWh/year → $90–$105/year
• Older 10-year-old fridge (500L): ~500–600 kWh/year → $150–$180/year

So the FAB38RRDAU sits between a modern efficient fridge and an old inefficient one. It uses about 40–50% more energy than a comparable A+++ model, but it’s not as bad as a 15-year-old fridge. Over a 10-year lifespan, the extra cost compared to an efficient model could be around $500–$700.

Why Is It Less Efficient?

Several factors contribute to the FAB38RRDAU’s higher energy consumption:

• Retro design: The rounded shape and thick insulation are less space-efficient than modern rectangular designs, meaning more surface area for heat transfer.
• Compressor technology: It uses a fixed-speed compressor, which runs at full power whenever cooling is needed. Inverter compressors, which adjust speed, are more efficient.
• Large capacity: At 519 liters, it’s a big fridge, and larger units naturally use more energy than smaller ones.
• No smart features: Some modern fridges have vacation modes or adaptive defrost, which the FAB38 lacks.

That said, the FAB38’s insulation is still decent, and it does have an energy-saving mode (a switch that reduces power when the ambient temperature is below 25°C). Using that mode can reduce consumption by about 10%.

How to Reduce the Running Cost

If you already own a FAB38RRDAU or are considering one, here are practical ways to lower its energy use:

• Keep it out of direct sunlight and away from ovens or dishwashers.
• Ensure the door seals are clean and airtight.
• Set the fridge to 4–5°C and the freezer to -18°C, not colder.
• Don’t overfill it, but also don’t leave it nearly empty—both extremes waste energy.
• Let hot food cool before putting it inside.
• Use the ‘energy saving’ switch if your kitchen is cool.

Frequently Asked Questions

Is the Smeg FAB38RRDAU worth the high energy cost?

That depends on your priorities. If you value the unique retro aesthetic and can afford the extra $50–$100 per year compared to a standard fridge, then yes. If you’re looking for the lowest lifetime cost, you’d be better off with a modern energy-efficient model.

How much does it cost to run per day?

At 421 kWh/year, that’s about 1.15 kWh per day. At $0.30/kWh, that’s $0.35 per day, or about $10.50 per month.

Does the FAB38RRDAU have an energy-saving mode?

Yes, it has a switch that reduces power consumption when the room temperature is below 25°C. It’s usually located near the thermostat.

What is the lifespan of a Smeg FAB38RRDAU?

With proper maintenance, a fridge like this can last 15–20 years. The compressor is the most likely part to fail, but Smeg offers a 2-year warranty (and in some regions, 5 years on the compressor).

Is the FAB38RRDAU noisy?

It’s not particularly noisy, but the fixed-speed compressor can be slightly louder than an inverter model when it kicks in. Typical noise levels are around 40–45 dB, which is comparable to a quiet conversation.

Can I use the FAB38RRDAU in a garage or outdoor area?

It’s designed for indoor use only. Operating it in temperatures below 10°C or above 35°C can cause it to work inefficiently or even stop cooling properly.
