The problem
Nobody wastes water on purpose, it goes while you wait
In a normal installation the hot water lives in the heater and the pipe is full of cold water. Open the tap and all of that cold water goes down the drain before the hot arrives. It happens on every shower, every day, in every bathroom of the house.
And it bills you twice
You pay for it on the water bill, then pay again in the time you spend standing there waiting.
Dry season makes it worse
Where water arrives on a schedule or by truck, every liter down the drain is a liter you will miss later.
How it works
Hydroloop® is a hydro-return
You press the button, or trigger it from your phone. An internal 12 V pump pushes the cold water trapped in the hot line back to the heater through the cold line. When hot water reaches the unit thermostat, the pump shuts itself off. Open the tap and it runs hot.
The sequence plays on its own. Tap any step to see it.
Hydroloop® does not save gas: gas consumption stays the same. It saves water, time and money.

How much water your house is throwing away
Move the values to match your reality. The defaults are the figures Hydroloop publishes: 7,300 liters and 18 hours a year per person.
This is an estimate, not a promise. Real savings depend on the distance to the heater, the pipe diameter and your water rate. The price per cubic meter changes in every city, so use the one on your bill.

Después de la sequía del 22, obligado
Quien vivió la crisis del agua en Monterrey entiende. Esto debería venir de fábrica en todas las casas nuevas. Instalación certificada impecable y el consumo eléctrico es una broma de tan bajo.

Con calentador instantáneo, pregunta antes
Tengo calentador instantáneo de alto flujo y necesité una bomba presurizadora de 1/6 para que encendiera. Soporte me acompañó a distancia hasta que quedó. Funciona muy bien, solo contempla ese posible extra.

Lo digo como plomero
Me ha tocado instalar varios. La guía rápida está clara, el equipo se siente bien hecho y el termostato corta justo donde debe. De lo importado que he visto, nada se instala tan fácil como esto.

FAQ
What everyone asks before buying
Do I need one unit per bathroom?
It depends on your plumbing. If the fixtures run in line, one unit at the last point can be enough as long as the secondary branches are short. If the plumbing is branched, where each fixture gets water from its own line, every point that wants instant hot water needs its own unit. A plumber can tell you which one you have, or our support team can assess it remotely.Which heaters is it compatible with?
Any of them. On high flow tankless heaters you may need a 1/6 hp booster pump to guarantee ignition. It does not apply in every case, so the sensible order is install first and evaluate.Does it save gas?
No. Gas consumption stays the same. What it saves is water, time and money.Manual or WiFi?
Manual is for anyone who wants simplicity: one click and the system stops on its own at temperature. WiFi is for anyone who wants scheduled start times and phone control, even from outside the house. WiFi needs a good signal where the unit is installed.Are there similar products?
Similar yes, identical no. The goal is the same but they get there another way, almost always at a higher price because they are imported, and with a harder install.Do you ship anywhere?
Yes. In some cases shipping is free depending on our distribution network and your location. If it does not apply, we quote it with your postal code.What payment methods do you take?
Credit and debit cards, Apple Pay, Google Pay, installments, OXXO, SPEI and bank transfer. Cash at authorized points of sale.What does the warranty cover?
One year on manufacturing defects for the recirculation unit and the control module, with proof of purchase. It goes up to two years when our certified crew installs it, and in that case it also covers the installation. It does not cover incorrect installation, electrical or plumbing faults in the building, sudden pressure swings, impacts, unauthorized service or accessories we do not manufacture.
