Elias is a man who works with his hands in a tiny shop on a street that smells like rain and old metal. He fixes watches and he spends his days looking through a glass lens that he holds in his eye socket and he never talks about the history of time.

He does not care if a watch was worn by a king or if the brand was started in a shed in the mountains a hundred years ago. Elias only cares about the teeth on a gear and he cares about the width of a pin. If a pin is too thick by a fraction of a hair then the watch is a paperweight and it does not matter how much the customer paid for it.

He lives in a world where the physical truth is the only truth and he has no time for the stories that people tell to sell things. He once told me that a watch is just a box of constraints and if you ignore the constraints then you are just carrying around a heavy bracelet that tells lies.

The Measurement of Survival

Ana is not a watchmaker and she does not have a lens in her eye but she is currently living in the same world of hard physical truths. She is standing in her bathroom in Chișinău and she is holding a tape measure that is cold and sharp.

She has sneezed seven times in a row because the dust behind the old water heater is ancient and dry and it is stinging her nose. Her head feels heavy and her eyes are red and she is trying to read the numbers on the metal tape while the light in the room flickers.

Between the cold water pipe and the edge of the shower cabin there is a gap of fifty-two centimeters and that is the only number that matters in her life right now. She has a piece of paper in her other hand and it is a printout of a new boiler and the picture is bright and the tank looks like it was carved from a single piece of white stone.

The page tells her that the boiler is a marvel of modern engineering and it talks about the heritage of the maker and it lists the energy class in a green box. It tells her about the warranty that lasts for years and it tells her about the special coating on the inside that prevents rust.

Ana looks at the paper and then she looks at the fifty-two centimeters on her wall and she feels a rising heat in her chest. She has to click a small grey button on her phone and then she has to scroll past the marketing text and then she has to find a table that is hidden at the bottom.

The diameter of the unit is buried in the eleventh row of a technical list and it sits right below the weight of the cardboard box it comes in. The page treats the width of the object like it is a minor detail and it acts like the question of whether the object can physically enter her home is a footnote.

A Confession from the Supply Chain

I am a supply chain analyst and my name is Astrid J.P. and I have spent most of my career looking at how products move from a factory floor to a person’s house. I have spent years building databases and I have spent years looking at how websites are designed and I have to make a confession.

I used to think that the way we showed information was the way people wanted to see it and I was wrong. I was very wrong because I was looking at the world through a screen and I was not looking at the world through a bathroom door.

I thought that people bought things because they liked the brand or because they liked the color or because the price was a few coins lower than the next shop. I believed that the story of the product was the thing that closed the sale and I helped design systems that pushed those stories to the front.

I was wrong because a person who needs hot water is not shopping for a story and they are shopping for a solution to a geometry problem. When we bury the dimensions of a product we are not being helpful and we are actually trying to trap the customer.

The industry wants you to fall in love with a model because once you have decided that you want that specific heater then you are more likely to change your life to fit it. You might hire a plumber to move a pipe or you might cut into a cabinet or you might just pay too much for a smaller tank because you are tired of looking.

If the website showed you the size first then you would see that ninety percent of the catalog does not fit your house and you would leave the site in thirty seconds. The companies do not want you to leave so they hide the truth in the eleventh row and they hope you do not own a tape measure.

Inches Decided by Architects

This is a form of routing and it is not shopping. Real shopping is when you have the power to filter the world based on your own reality and your reality is measured in centimeters.

In Moldova we live in apartments where every inch was decided by an architect fifty years ago and those architects did not care about the giant round water heaters of the future. They left us niches and they left us corners and they left us narrow doors.

When you go to Bomba.md you start to see a different way of doing things because they understand that a slim model is not a luxury and it is a necessity for a person living in a real flat. They know that if the heater is fifty-five centimeters wide and your gap is fifty-two then the heater might as well be on the moon.

The first thing that fails in the universal fit lie is the idea that one size can work for everyone if they just try hard enough. We are told that these objects are designed for the modern home but the modern home is often a place of constraints.

We have washing machines and we have storage bins and we have pipes that run at odd angles and we have walls that are not perfectly straight. A water heater is a large heavy object and it is full of water and it cannot be squeezed or bent. It is a hard truth in a soft world of marketing.

When a company hides the size they are telling you that your home is the problem and they are saying that their product is perfect and your bathroom is just too small. I have seen families who bought a hundred-liter tank because they wanted long showers and then they realized they had to remove the door frame just to get it inside.

Hanging Motorcycles on Walls

The second thing we ignore is the weight of the water itself. A liter of water weighs one kilogram and a hundred-liter tank weighs a hundred kilograms plus the weight of the steel.

You are hanging a small motorcycle on your wall and you need to know where the studs are and you need to know if the wall can hold the weight. The product page will tell you about the digital display and it will tell you about the wifi connection but it will not tell you if your wall will crumble under the load.

We treat these technical facts like they are boring because they are not shiny and they do not make for a good television ad. But the boring facts are the ones that keep the heater on the wall and they are the ones that keep your floor dry.

I feel another sneeze coming on and I think about Ana again. She is still standing there and she is looking at the screen and she is feeling like the world is not made for her. She is starting to realize that the universal fit is a myth and she is starting to look for the words slim or compact.

Brands like Thermex or Atlantic or Ariston have started to make heaters that are tall and thin like a person standing in an elevator. These are the models that actually solve the problem because they respect the fifty-two centimeters.

The third problem is the energy class. Everyone wants an A or a B because we want to save money and we want to be good to the planet. But the energy class is often tied to the thickness of the insulation. If you want a heater that stays hot for a long time then you need thick foam around the tank and thick foam makes the tank wider.

This is the trade-off that nobody explains to you. You can have a very efficient heater that is too fat for your corner or you can have a thinner heater that loses a little more heat but actually fits in your house. The industry wants you to feel guilty for picking the less efficient model but they do not offer you a way to stretch your walls.

Three Numbers to Rule Them All

If I were designing the world I would make every product page start with three numbers. I would make them show the height and the width and the depth in big black numbers at the very top of the page.

I would make it so you could not even see the color or the price until you confirmed that you had enough space. We do this with shoes and we do this with clothes and we do not buy a shirt because it has a great story if the shirt is three sizes too small.

But we treat appliances like they are magical objects that can transcend the laws of space and time. We act like we can just make it work because we want it to work.

The 4th, 5th, & 6th Constraints

The Plumbing: Sometimes the heater fits the gap but the pipes are in the wrong place and you have to use flexible hoses that look like silver snakes. The makers know where the pipes are but they do not want to talk about it because it is another reason for you to not buy their product.

Capacity: A family of four that takes quick showers can live with an eighty-liter tank if the heater is fast. But capacity is also about space. If you can only fit a fifty-liter tank then that is your capacity and the number of people in your house does not change the size of your wall.

Materials: In parts of Moldova the water is hard. A stainless steel tank can fail at the welds; an enamel tank can crack. You pick the material that lasts and you pick the size that fits and then you look at the price. If you do it in any other order then you are just guessing.

The Seventh Measure: Time

The seventh thing is the delivery and the speed of the service. When your old heater breaks and it starts to leak on the floor then you do not have a week to wait for a box to arrive from another country. You need a heater today and you need it in three hours.

You need someone who has the stock in a warehouse nearby and you need someone who knows the streets of Chișinău or Bălți. This is where the local shops win because they are living in the same reality as you are. They know that a broken heater is an emergency and they know that hot water is not a luxury.

Ana finally finds the slim model she needs and it is forty-four centimeters wide and it leaves her a few centimeters of space on either side so she can breathe. She feels the tension leave her shoulders and she puts the tape measure down on the sink.

She has stopped sneezing and the room feels a little brighter even with the flickering light. She is going to have hot water again and she did not have to break her wall or move her pipes. She found the truth in the eleventh row but she had to fight for it and she had to ignore the brand heritage and the energy class boxes.

She was a watchmaker for a moment and she looked at the gears of her life and she made them fit. We should all be more like Elias and we should look at the pins and the teeth and the microns. We should not be afraid to demand the boring numbers and we should not let a shiny picture distract us from the reality of our own homes.

The world is full of things that want to be in our houses and we are the ones who decide if they are allowed to stay. A product is not a dream and it is not a story and it is a physical object that takes up space and it must respect the boundaries we have.
