WhatsApp engagement was excellent. They diagnosed the problem remotely with my water heater but given they weren’t the best fit with the device manufacturer, they recommended a different path with the manufacturer. They were awesome to work with.

ENGLISH-SPEAKING · QUOTE BEFORE ANY WORK
Winter: no hot water?
When the cold arrives, water heaters run longer every day and faults show up suddenly: the shower that goes cold halfway through, the esquentador that won't light in the morning, the breaker that trips when the tank switches on.
If it's happening now, WhatsApp us a photo of the unit and its label (brand, model and size) or a short video of it trying to start. It helps us understand the likely cause before we reach your home.
Which one do you have?
Portuguese homes usually have one of three. An esquentador is a small gas heater on the wall, often in the kitchen, that heats water as it flows. A termoacumulador is an electric tank, often in a bathroom, a utility area or above a false ceiling, that keeps a store of hot water. A caldeira (boiler) heats water and often radiators too. Not sure what your landlord installed? Send a photo and we'll tell you.
What we do
Water heater (esquentador) repair
Won't light, cuts out mid-shower, lukewarm or fluctuating water, drips or leaks.
Electric hot-water tank repair
Not heating, dripping from the valve or the tank, tripping the breaker, noisy.
Replacement
When a repair no longer makes sense, we help you choose a unit that suits your home and swap it.
New installation
Hot-water tanks and water heaters for renovations and new homes.
Boilers
Repair, replacement and installation.
We repair, replace and install water heaters of every kind, including gas esquentadores. Work on the gas supply itself is done by a certified gas company.
Common faults and what they usually mean
The esquentador won't light or cuts out
Many esquentadores light with batteries. When they run low, it clicks but won't light, or goes out soon after. Try new batteries before you call us: sometimes that's all it is. If it still fails, it may be water pressure, the flame sensor or the flue, and that's a job for us.
Lukewarm water, or hot then cold
Usually limescale in the heat exchanger, low water flow or a worn regulating part. Tell us whether it happens at every tap or just one: that separates a heater fault from a pipe problem.
The hot-water tank drips or leaks
A few drops from the safety valve while it heats can be normal. Water coming from the tank itself, or rust around it, usually means the tank is failing. Switch it off at the fuse box, close the cold-water inlet and message us.
The breaker trips when the tank switches on
Often the heating element or the thermostat. Leave it off at the fuse box and don't switch it back on until it has been checked.
Cracking, whistling or rumbling
A typical sign of limescale on the element, in the tank or in the heat exchanger. Not an emergency, but worth sorting before it shortens the unit's life.
Smell of gas? Close the gas valve, open the windows, don't touch light switches, leave the home and call 112.
Repair or replace?
We tell you honestly what makes sense. What counts: the unit's age (a heater over 10 to 15 years old rarely justifies an expensive part), the price of the part against a new unit, and the tank: a hot-water tank that leaks from the tank itself can't be repaired, only replaced.
