Getting a natural gas fired (while it is still legal in California) tankless water heater installed in a couple of days. Tell me why I'm making a big mistake.

Air Fryer/Mini Convention Oven. Even make hard boiled eggs in there without waiting for a pot of water to boil.

Save my meat drippings and slather some asparagus and broccoli in garlic and meat sauce, cook 2-5 minutes depending on frozen/size of floret. BAM! Meat and veggies.

I make 90% of my meals in the Air Fryer, best thing ever. Seldom add any oil, except a pat of butter when flipping over a steak or making some veggies and don't want the heavy meat drippings.

Sausages or Chicken. frozen? 7-9 minutes at 400 in the Air Fryer, again no oil. Slather it with some Sirachca and Green Onions, and I'm good. Or sprinkle a tiny bit of Italian Sauce and Moz cheese in the last minute for Parm Style.

Reheat a slice of pizza on cheat day or kid meal? 2-3 minutes in the airfryer, nice melted cheese and crispy without a hint of sogginess. Ditto for empanadas and toast and even pancakes (I make dozens of silver dollars in advance and freeze them, make them for...


is there a good brand you recommend?

I'd say a microwave is far more energy efficient as it uses a strong but short lived current to heat up the water (and other) molecules of the food/drinks from the inside, whereas a stove wastes a lot of energy in heat.

From an economics standpoint, I'd guess a gas cooktop will cost you less than a microwave for heating water. Sure, the gas cooktop will release 3x or 4x the total amount of energy into your house, but that energy is very cheap. The microwave does most of its heating in the natural-gas energy plant somewhere far away.

I have an energy meter called the Kill-a-watt. You plug it into the wall outlet and then you plug your appliance into the kill-a-watt and have the energy measured. You can get instantaneous wattage and amperage as well as a running total of the kW/hr.

What I've learned is that things that run continuously can add up over time! The refrigerator isn't quite "continuous," but it's the big one that's always plugged in. If you have a desktop computer that doesn't sleep you might be looking at 100 watts --> 2.4 kW/hr per day.

Small appliances like microwave, coffee maker, rice maker, toaster oven, etc. don't add up to much because they don't run for very long. My tiny rice maker is 100 watts and only runs for 20 minutes from time to time; that's only 1/3 kW/hr per use.

Cooktop and oven (240v so I can't even measure them) just don't run for very long. Ty are both 30 amps, so theoretically 7.2 kW/hr each for an hour of maximum usage. But nobody runs these for an hour full-out.

I have electric dryer. That is 30 amps by 240v and runs for 30 minutes or more. That's brutal. I usually pre-dry towels and other heavy items with the "solar powered clothes dryer" in the back yard for a while before throwing into the dryer. The dryer is one appliance I actually try to reduce usage and/or shift to off-peak-pricing time.

Washing machine and dishwasher are interesting. Neither uses much electrical power except if on hottest setting (or "sanitize" for the dishwasher). In those modes, you're looking at 1 kW/hr per run. Otherwise it is less than 1/4 of that.

My desktop computer is about 75 watts but is connected to a 250 watt 65-inch TV. It also runs a lot.

use a microwave at the local 7/11 when you're warming up a burrito.

Eww!

I like the electric kettles, 1500watt to 1800 watt.

They are also nice as you you don't have to worry about boiling away the water and destroying your stove top kettle (as nameless members of my household have done...)

Depending on the destination, we'll actually travel with our air fryer. Not joking. We've legit have had air fryer parties. If we're doing a one nighter at a hotel within driving distance we always bring it. If we're going with others our room usually ends up being the party spot for the late night snacks.

I think an air fryer is just like the convection setting on my toaster oven.

I had a toaster/convection oven I used last summer in lieu of buying an air fryer, and it took far longer to make the food than a dedicated air fryer. The air fryer has a much smaller space and cooks it faster, more evenly, too. You can also toast bread in an air fryer if you want, and it's 1-2 minutes just like a regular toaster.

Cleanup is far easier than a convection oven, just pull out the basket and rinse in the sink, and it's ready to go. Dump out the crumbs and whatnot and let the sink drainer collect it, rather than getting crumbs on the counter/floor by wiping the inside of a convection oven with a cloth/paper towel. Also no need for aluminium foil unless the dish is really greasy or full of sauce.

It's also easier to collect bacon/meat fat in an airfryer, just pour out the basket contents into a jar. Unlike a convection oven, where you have to handle the pan carefully or dribble it all over.

Right now I have one made by Instant as in "Instapot": the "Vortex Plus". I searched high and low for an American one, but sadly, none I could find. I also owned a cheap generic with analog dials which was just as good.

I find convection ovens not to cook the same or as fast as the air fryer with the bottom removable basket.

Also, you can get small air fryers if you want one for an office/workshop.

I don't like microwaved water for my tea.


Ditto, it's not the same somehow.

It's amazing as well if you have kids. Cooks frozen nuggets (I know bad) in about 8 minutes that are crispy and not mushy. And as you say the crumbs are easily gotten rid of without taking up dishwasher space. Does well for boiled eggs the few times I've done it. Bacon actually does well, but you have to do multiple rounds for just 1 package.

We have an Instapot as well, but we find a dedicated air fryer to be better. Only plus with Instapot is the ability to sear meat. Basically you could cook any meal in say your standard hotel room that that maybe will have a microwave. My chef buddy made some insane Italian beef out of an Instapot when we shared a room for a concert in South Bend, IN. Better than any I've ever had. My issue with them is they're just too damn big and heavy. Don't like the lid. The pressure cooking part requires it though.

Haven't seen anyone mention this about the tankless heaters yet. They are finicky if you try to set the temperature to less than high when you turn the water on. To the point that my wife swore they didn't work, because she never turned the hot water up, so she only got cold water. Basically you have to let the heater know it needs to activate by turning the hot on all the way, then turning it down. So not perfectly efficient, but definitely better than heating up gallons of water that aren't being used.

the deal about an air fryer is that its small and enclosed in a way that holds the heat in better than a toaster oven...in other words, its hotter inside so it cooks faster and crisper and evenly.

If you eat frozen foods that need baking or frying, the air fryer is good...but i use my instapot much more because we eat more food from scratch... rice, stews, shredded meats, beans, corn on the cob, dried garbanzos, mashed potatoes, etc.

Reheat a slice of pizza on cheat day

If reheating and eating a slice of pizza is called a cheat day, what do you call the day where you actually ate 1/2 the extra large all meat pizza?

Half? More like 3/4.

Big Cheat Day.

Moderation doesn't work for me. Starve and binge is where it's at, historical human eating for 996,000 years. There's no evidence for 3 meals a day. 1 meal a day 5-6 days a week, then a 4 hour cheating window of DOOM. I'll also eat a small sub (no fries or chips) or a slice of pizza frozen from Big Cheat Day if I get midweek and weak so as not to skip leg day.

Also pigging out makes me feel like shit for the next 18-24 hours and gets me through the rest of the week of severely restricted calories because of the heartburn, sluggishness, guilt, and general malaise.

Not a fan of wet food. I make a carrot, beef, tomato stew once in a while, but I like my meat dry and crisp. Esp. Turkey. If it ain't just short of dessicated, it ain't done. Then slather it in Coleman's powdered mustard and super dry green peas with wasabi.

oh yeah also theres an outdoor snd indoor version. in CA you can get away with outdoor one. no meed for a vent pipe then.

The ones I have encountered overseas have an "idle" mode. If you go to shower, run laundry etc. - you need to turn the temp setting to an active mode and there are several to choose from depending on what you want the unit to do.


Didn't check the most recent one we used, but definitely looked closely at the other two, and no setting I could see. Just had to be assertive on wanting hot water.

I know a lot of folks in CA go for the outdoor installs. If it's going to be permitted, it also requires a dedicated, weather proof electric outlet (so add an electrician as well as a plumber to the total install cost).
Bear in mind that a foot of 3/4 inch copper pipe holds 0.0229 gal of water. So adding a ten foot stretch of pipe to your hot water line is about a quart of water that needs to be purged before the hot water shows up. If your fixture is pulling hot water at 1 gpm, then that's an extra 14 seconds. YMMV...

I did not know Coleman's powdered mustard was available outside of England. You're talking about that yellow mustard heavily fortified with horse radish, right? Very hot.
