If your boiler is faulty and no longer reliable, you need an experienced local heating and plumbing specialist who can assess the system, confirm whether replacement is the right call, and install the new unit.
100% Plumbing is based in Calpe and assesses, replaces and upgrades boilers across the Marina Alta.
One question settles most of this: is it one component or the whole system? An isolated fault in a boiler that is otherwise in good condition is usually a repair. A boiler that keeps failing in different ways is telling you something else.

When should a faulty boiler be replaced?
Replacement becomes worth considering when the system stops being reliable or the repair bills keep climbing. These are the usual warning signs:
- repeated breakdowns;
- regular pressure drops;
- poor radiator performance;
- unreliable hot water;
- unusual noises;
- leaks around the boiler;
- frequent lockouts or fault codes;
- an ageing system that is expensive to maintain.
None of these on its own forces a replacement. It is the pattern that matters: one failed component in an otherwise sound boiler is a repair, while several of the signs above appearing together usually points the other way.

Who can repair a boiler that will not start in Calpe?
Repair or replacement: which is better?
The decision comes down to four things: the age of the boiler, the type of fault, the condition of the wider system, and what the repair costs relative to a new unit.
Repair usually makes sense when
- the boiler is relatively recent;
- the fault is isolated;
- the parts are readily available;
- the system is otherwise reliable.
Replacement usually makes sense when
- the boiler is old;
- breakdowns keep recurring;
- the system is inefficient;
- heating or hot water performance is poor;
- repair costs are becoming disproportionate.
A professional inspection is what keeps you off both of the wrong paths: replacing a boiler that only needed a part, and spending repeatedly on one that is near the end of its life.
What affects the cost of replacing a boiler?
There is no single figure, because a boiler replacement is rarely just the price of the unit. These are the factors that move it:
The property and its demand
- the size of the property;
- the heating demand;
- the hot water requirements;
- how many bathrooms draw at once.
The condition of the existing system
- the state of the existing pipework;
- radiator performance;
- system pressure;
- gas connections, where applicable;
- the condition of valves and controls;
- whether other faults need fixing at the same time.
That second column is the one that surprises people. If the existing installation has problems of its own, they need resolving for the new boiler to work properly, and that forms part of the job rather than a separate one later.
What should be checked before installing a new boiler?
A replacement is not simply a like-for-like swap. Fitting a new boiler onto an installation that has not been assessed is how a new unit ends up underperforming from day one.
Before installation, a professional would normally assess:
- property size;
- heating demand;
- hot water requirements;
- existing pipework;
- radiator performance;
- system pressure;
- gas connections, where applicable;
- the condition of valves and controls.
Where the assessment finds existing faults, dealing with them during the replacement is almost always cheaper than returning to them afterwards.
Why local boiler replacement in Calpe and the Marina Alta matters
What the right boiler looks like depends heavily on the property, and the mix here is wide: apartments, villas, holiday homes, rentals and permanent residences, all with different demands.
Two patterns stand out. Holiday properties sit unused for long stretches and then need heating and hot water to work reliably the moment somebody arrives. And larger villas place far more demand on a system than a small apartment, so a unit sized for one is wrong for the other.
A local professional can assess the installation as it actually is, spot related faults, and recommend a boiler that suits the property rather than the catalogue.
