The magic oven that can save you £266 a year…

The chicken was golden on the outside and juicy on the inside. Baked potatoes are crispy and hot. The vegetables were cooked to perfection, the sauce was rich and the Yorkshire puffed to perfection.

It’s a roast dinner. .. but not as you know. All Sunday lunches were cooked not on a traditional oven or griddle, but in my brand new air fryer.

For the uninitiated, an air fryer is like a supercharged mini fan oven. It can be baked, roasted, crisped, reheated or fried (with minimal fat or oil), from fish and chips to coated potatoes, cakes to full dinners – all for half the cost of the time of cooking.

And, as the cost of living crisis continues to escalate, it uses a fraction of the energy of a traditional oven – just 14p a day, compared to 87p a day to run. No wonder sales skyrocketed and recipes went viral.

Sarah is going to cook a roast dinner in the air fryer – this article is about smart appliance swaps you can do to save money during the cost of living crisis

So what’s the science behind it? What other alternatives can save you money? Here’s your guide to smart home swaps that could save you hundreds of dollars on energy bills.

exchange yours. . . air fryer oven

How it works: “An air fryer is a small oven with a very powerful fan,” says Dr Jakub Radzikowski, culinary education designer at Imperial College London. “It has a helical heating element and a fan that forces air around it. While a standard fan oven has some airflow, in an air fryer it’s more of a hurricane.

This “hurricane” effect, combined with its small size (air fryers range from 1.5 liters to 7.3 liters, compared to 60 liters in ovens), means that food cooks much faster than in the oven. A whole chicken is ready in 45 minutes and a baked potato is ready in 20 minutes. This efficiency – and the fact that you’re heating a smaller space – means less electricity needed, which saves money.

I put mine, a 5.2 liter model from cookware maker Ninja (£130, argos.co.uk) to the ultimate test, roasting 1.5kg of chicken, 800g of apples ground, carrots, vegetables, Yorkshire pudding and gravy for four. Although the downside is doing it in batches – I can put in chicken and potatoes, then vegetables, then Yorkshire – it’s all on the table in less than an hour.

Cost comparison: Figures from energy company Utilita and Icelandic supermarkets show the cost of running a standard electric oven is 87p a day (£317.55 a year) based on one use average daily. However, an air fryer will cost you 14 pence a day, or £51.10 a year.

Recent reports have warned that cooking a two-hour Sunday roast in a 3kW oven will cost £5.16 by January. A one hour air fryer only costs 18p.

Of course, if you already own an air fryer, the ultimate savings are available – and the other gadgets detailed here, because you’ll save money right away. However, based on the cost of my air fryer, I will calculate the energy savings in six months, after which it is pure savings.

You’ll save: £266.45 per year.

dryer for dehumidifier

How it works: A clothes dryer uses an electric motor to spin a bucket of wet clothes, while a fan circulates the warm air.

Electric heaters heat the air and a thermostat maintains the temperature throughout the cycle. Many machines have moisture sensors to indicate when the load is dry.

All this makes the dryer one of the most expensive appliances. The cheapest option is to dry your clothes on a clothes rack, but using a dehumidifier is quicker.

Dehumidifiers (from £39, amazon.co.uk) for drying out damp or moldy spaces. They work by drawing hot air into a refrigerated metal coil via a fan. The hot air contracts, leaving condensation water that accumulates inside the machine.

If you hang wet clothes on a rack in a small room, close doors and windows, and use a dehumidifier, even a thick towel will dry out in 6-8 hours.

Cost comparison: The average cost of running a tumble dryer is £1.46 per item, or £177.63 per year. Use a dehumidifier for just 7p each, or £8.52 a year (assuming laundry is done every three days). If you have to buy new, you’ll save the same cost in three months.

You’ll save: £169.11 per year.

slow cooker baking sheet

How it works: Cooking on the hob is done by heat transfer: the energy heats the “crown”, which transfers the heat to the metal pan. These, in turn, heat the food from the base.

Heat – and money – can be lost through the sides and top of the pan (if the lid is not used).

A slow cooker, a well-insulated pot with a lid, can heat up food in a matter of hours. It may take longer than a traditional griddle (e.g. 6 hours for a chili versus 90 minutes for a griddle), but a slow cooker is very efficient. “Slow cookers typically consume 100W of power, and an average cooktop of up to 3kW can cook the same meal at two-thirds the price,” said Ben Gallizzi, energy expert at Uswitch. .com.

Cost comparison: The slow cooker costs 22p a day to run, or £80.30 a year. A gas cooker costs around 37 pence a day, or £135.05 a year.

You’ll save: £54.75 per year.

Kettle for coffee machine

Why it works: We all feel guilty for overfilling kettles that heat water electronically. The more water, the harder this coil will work and the longer it will take to boil – and the more energy it will use.

An air fryer is like a miniature supercharged fan oven.  It can be baked, baked, crisped, reheated or fried (using minimal fat or oil) from fish and chips to potatoes and cakes to full dinners - for as little as half the time in the oven

However, coffee machines that use pods can only heat one cup of water. If you prefer tea, omit the pods and use a machine to boil the water.

Its heating element is much smaller than that of the kettle and drives the water along its way to the pods. It only takes 30 seconds.

Cost comparison: It can take 4.5 minutes to boil a full 2 ​​liter kettle. This time it costs around 21p, or £153.30 if cooked twice a year. According to comparison site Eco Cost Savings, a coffee machine costs 1 pence per use, which is up to £7.30 a year if used twice a day.

You’ll save: £146 per year.

hair dryer iron

How it works: If you’re using an iron, consider switching to a hair dryer. Experts say that blow-drying is as effective at dissolving creases as pressing them down with a hot iron.

That’s because the hair dryer works like a hand-held steam engine: hot air loosens the bonds between long-chain polymer molecules in the fabric, loosening them, allowing wrinkles to fall out. And it’s much faster.

Cost comparison: A 1100 watt iron costs 12 pence for 30 minutes – £12.48 a year if you iron twice a week. A powerful steam model can cost £19 a year.

Uswitch says the hair dryer costs as little as 5p per use (counting around 8 minutes on the highest power setting), or £5.20 a year

You will save: £13.80 per year.

toaster

How it works: The grill cooks food from the top via electronically controlled heating elements inside the oven. A toaster does the same thing, but it spins sideways, transferring heat from left to right inward. “It’s a very direct round, and it’s a lot less. You don’t need to heat the whole oven,” says Dr. Radzikowski.

Ben Gallizzi added: “Waiting for the grill to heat up wastes electricity, and the distance between the elements and the bread means more energy is needed.

Cost comparison: A two-slice toaster costs 88 pence per use (assuming a toasting time of 2.5 minutes). The grill takes a total of 5 minutes and costs £2.26. Use every morning for a year and the difference is £321.20 and £824.90.

You will save: £503.70 per year.
