Stay warm and energy-efficient on the Costa Blanca
As cooler months approach, many homeowners in Benissa, Moraira, and Calpe begin to think about comfort and energy efficiency. While the Spanish winter is mild compared to Northern Europe, the humidity and evening chill can make homes surprisingly cold.
That’s why preparing your home heating system before winter is essential — ensuring safety, warmth, and lower energy costs.
If you want expert assistance with inspections, boiler checks, or underfloor systems, visit the Heating Services page from 100% Plumbing to learn how professionals keep systems running efficiently.
Why pre-winter maintenance matters
Unlike colder countries, many Costa Blanca homes are built for summer ventilation, not winter insulation. As a result, heating systems often go unused for months — until suddenly needed. That’s when problems surface.
Regular maintenance helps you:
-
Avoid system breakdowns during cold spells
-
Reduce heating costs by up to 25%
-
Extend boiler lifespan
-
Prevent leaks and air blockages
-
Maintain safe operation
Professional servicing through local Plumbing Services ensures every component, from valves to pipes, performs at its best when temperatures drop.
Bleed radiators and check water pressure
When radiators feel warm at the bottom but cool at the top, trapped air is blocking circulation. Bleeding the system restores balance and prevents uneven heating.
Also, check the boiler’s pressure gauge — it should be between 1.0 and 1.5 bar.
If it’s too low, the system won’t circulate water properly. Technicians from 100% Plumbing can inspect your radiators and perform a full central heating system calibration through their Heating Services.
Inspect and service your boiler
Your boiler is the heart of your heating system. Over time, scale, rust, and dust can reduce efficiency and increase energy use.
Before winter, book a professional inspection to ensure:
-
Clean heat exchangers
-
No gas leaks
-
Proper thermostat response
-
Safe ventilation
If your boiler is old or inconsistent, consider replacing it with a modern, high-efficiency model. Learn more about replacements and upgrades in the Heating Installation Services section.
Clean, protect, and insulate your pipes
Heat loss through uninsulated pipes is one of the most common — and avoidable — causes of inefficiency. Adding thermal insulation to exposed pipes, especially in basements, terraces, or garages, helps maintain temperature and prevents freezing.
The Plumbing Services team at 100% Plumbing can replace corroded pipes, seal minor leaks, and add insulation materials suited to the Costa Blanca’s humidity levels.
Consider renewable heating solutions
Spain’s sunny climate offers ideal conditions for solar-assisted heating systems, which use solar energy to preheat your water and reduce gas or electricity consumption.
This hybrid approach not only cuts bills but also lowers your home’s carbon footprint.
To explore how solar energy can complement your boiler or underfloor heating, check out the Solar Energy Services section.
You can also consult the Instituto para la Diversificación y Ahorro de la Energía (IDAE) for official guidance on energy efficiency in residential heating systems across Spain.
Test thermostats and smart controls
Smart thermostats allow you to maintain an ideal indoor temperature while optimising energy use.
These devices are perfect for second homes in Benissa or Moraira, enabling remote monitoring and control via smartphone.
100% Plumbing’s technicians can integrate smart controls as part of a complete heating system service, ensuring compatibility with your existing solar or boiler installation.

Frequently asked questions (FAQs)
1. When should I service my heating system in Spain?
The best time is autumn, before the colder nights begin. This ensures your boiler and radiators are ready for increased use.
2. How often should I bleed my radiators?
Once a year, preferably before winter. Trapped air reduces heating efficiency and can lead to cold spots.
3. Are solar water systems effective in winter?
Yes. Even in winter, the Costa Blanca receives enough sunlight to significantly preheat domestic water, lowering energy demand.
4. Can I use smart thermostats with older heating systems?
In most cases, yes. A technician can install adapters or compatible controls to improve performance and manage temperature remotely.
5. How can I make my heating more eco-friendly?
Combine your current boiler with solar assistance, upgrade to energy-efficient radiators, and schedule regular servicing to minimise energy waste.
