Types of Underfloor Heating Systems We Install
Choosing the right system depends on your property type, budget, flooring, and existing heating setup. At Dublin Plumber 24 hrs, we install both water-based and electric underfloor heating systems across Dublin, ensuring the system matches your home’s requirements.
Water-Based (Wet) Underfloor Heating
Water-based UFH circulates warm water through a network of pipes installed beneath the floor. These systems connect to your existing gas boiler or heat pump and are ideal for:
Whole-house heating
New builds and major renovations
Homes aiming for maximum energy efficiency
Wet UFH systems operate at lower temperatures than traditional radiators, reducing energy usage while delivering consistent warmth throughout the room. They are particularly cost-effective for larger areas.
Electric Underfloor Heating
Electric UFH uses heating mats or cables installed beneath the floor surface. It is commonly used in:
Bathrooms
Kitchens
Small rooms or single zones
Retrofit projects with limited floor depth
Electric systems are quicker to install and ideal for targeted comfort heating. They are often chosen where installing pipework is not practical.
We will assess your property and recommend the most suitable UFH system for your Dublin home.
Underfloor Heating Repairs & Fault Finding in Dublin
Signs your underfloor heating needs repair include: floor areas that are warm in some zones but cold in others, the system running constantly without reaching target temperature, unusual increases in energy bills, thermostat displays showing error codes, or complete loss of heat in one or more zones.
Early diagnosis prevents minor faults from becoming costly system failures. Dublin Plumber 24 hrs provides same-day fault assessment across Dublin for both water-based and electric UFH systems.
Common issues we fix include:
Cold spots or uneven heating
Thermostat faults or control issues
Airlocks in water-based systems
Leaks in pipework
Electric system failures
System not heating up properly
UFH systems are designed to be low maintenance, but when faults occur, accurate diagnosis is essential. We use proper testing methods to identify the root cause and carry out targeted repairs to restore performance efficiently.
If your heating system in Dublin is not working correctly, contact Dublin Plumber 24 hrs for expert assessment and reliable repair solutions.
Underfloor Heating Repairs & Maintenance
Although underfloor heating systems are designed to last for decades, faults can occasionally occur due to wear, installation issues, or component failure.
Our Dublin engineers diagnose and repair all common underfloor heating problems, including:
- Cold spots across the floor
- Rooms not reaching temperature
- Thermostat failures
- Manifold leaks
- Airlocks in water systems
- Low system pressure
- Circulation pump failures
- Faulty actuators
- Wiring problems
- Electric heating mat failures
- Smart thermostat issues
- Uneven heat distribution
Our goal is to identify the fault quickly and restore your heating system with minimal disruption.
Underfloor Heating vs Radiators – Which Is Better for Dublin Homes?
Underfloor heating distributes heat evenly across the entire floor surface, eliminating cold spots and operating at lower water temperatures (35–45°C) compared to radiators (60–75°C). This makes UFH 15–25% more energy efficient when connected to a heat pump or modern condensing boiler.
Radiators heat rooms faster — typically within 15–20 minutes — while water-based UFH takes 30–60 minutes to reach full temperature. For homes where heating is used intermittently, radiators may be more responsive. For homes that maintain consistent heating schedules, UFH delivers lower running costs over time.
Underfloor heating also frees up wall space, removes the need for radiator maintenance, and works silently — making it the preferred
choice for open-plan living areas, bathrooms, and new builds in Dublin.

Underfloor Heating with Heat Pumps in Dublin
Underfloor heating is the ideal companion system for air-to-water heat pumps. Heat pumps operate most efficiently at low flow temperatures of 35–45°C — exactly the range at which water-based UFH operates. This combination can reduce home heating costs by 40–60% compared to a gas boiler with radiators.
SEAI currently offers grants of up to €6,500 for heat pump installation in Irish homes. Pairing a SEAI-supported heat pump with a new underfloor heating system is one of the most cost-effective long-term heating upgrades available to Dublin homeowners in 2026.
Dublin Plumber 24 hrs installs both heat pump and underfloor heating systems, offering a complete integrated solution from a single qualified team.
