If your shower has no hot water in Calpe, you need an experienced plumber or heating specialist who can identify whether the fault is in the shower itself, in the water heater or boiler, or somewhere in the wider hot water system.
100% Plumbing is based in Calpe and diagnoses shower, boiler, valve and hot water system faults across the Marina Alta.
Start with one check: run a hot tap somewhere else in the property. That single test narrows the problem down more than anything else, and it takes seconds.

Why does my shower have no hot water?
A shower can stop producing hot water for several reasons, and the shower itself is only one of them. The usual causes are:
- a water heater fault;
- a boiler problem;
- a faulty thermostatic mixing valve;
- low hot water pressure;
- a blocked or damaged shower valve;
- a thermostat or heating element fault;
- a wider hot water system problem.
Replacing the shower before knowing which of these applies is the most common way to spend money without fixing anything.
How can I tell if the problem is the shower or the water heater?
Run a hot tap elsewhere in the property, such as a kitchen or bathroom sink, and see what happens.
Hot water elsewhere, but not in the shower
The fault is probably local: the shower mixer, the thermostatic valve, the cartridge, or the pipework feeding that shower.
No hot water anywhere
The fault is more likely in the water heater, the boiler, or the wider hot water system, not in the shower at all.
This narrows things down quickly, although a professional inspection may still be needed to confirm exactly what has failed.
Can a shower mixing valve cause no hot water?
Yes. A faulty mixing valve or thermostatic cartridge can stop hot water reaching the shower properly. These parts control how hot and cold water are blended, and when they are worn, blocked or damaged the shower can stay cold while the rest of the property has hot water as normal.
The useful part is that this does not always mean a new shower. Depending on the fault, cleaning, adjusting, repairing or replacing the valve may be enough. A plumber can tell you which.
What if there is no hot water anywhere in the property?
Then the problem is almost certainly not the shower. The likely causes are:
- a faulty water heater;
- a boiler that is not starting;
- thermostat or heating element problems;
- pressure issues;
- a system control fault;
- another problem affecting the hot water supply.
In that situation our sistemas de agua caliente o calefacción central services are more relevant than a shower repair.

When does no hot water need urgent attention?
Losing hot water is not automatically an emergency, but it can become one depending on the property and the cause.
Needs attention sooner
- the problem affects the whole property;
- the water heater or boiler is leaking;
- there is a fault code or repeated system lockout;
- the property is a holiday rental or occupied accommodation;
- vulnerable occupants depend on reliable hot water;
- it is linked to an active plumbing leak.
Can wait for an appointment
- only the shower is affected;
- hot water works normally elsewhere;
- nothing is leaking;
- the system is running without fault codes.
If water is escaping, or there is another urgent fault alongside it, that is a case for emergency plumbing services.
Why local help in Calpe and the Marina Alta matters
No hot water is disruptive in any home, and more so in the mix of villas, apartments, rentals, holiday homes and businesses here. In a rental or a holiday property, it reaches a guest within the hour.
A local plumber can check whether the problem is isolated to the shower or linked to the wider system before anything gets replaced. That is what avoids paying for parts that were never at fault.
