Why Dublin Homeowners Are Reassessing Their Heating Systems
Irish population shows strong interest in energy efficiency because Dublin residents spend most of their household energy costs on heating their homes. Underfloor heating electric sytem have gained popularity among homeowners for decades because they provide comfort and clean design and maintain warm temperatures. The systems experience efficiency decline and complete system failure as they reach their aging point.
The combination of cold floor areas with leaks and faulty thermostats creates uncomfortable temperatures while causing your energy expenses to increase. That’s where Stillorgan Gas, the trusted experts in underfloor heating repair in dublin, come in.
If you’re weighing the pros and cons of repairing your underfloor heating system versus sticking with radiators, here are 7 key facts every Irish homeowner should know before making a decision.
Fact 1: Underfloor Heating Electric vs Radiator — Which Gives Better Comfort?
One of the biggest advantages of floor heating is even heat distribution. The system produces gentle heat that covers your entire floor space to create uniform room temperature and eliminate all cold areas. Radiators start by warming up the surrounding air before they can distribute heat to other areas.
The fast ascent of warm air creates temperature differences between floor and ceiling spaces in big rooms with inadequate insulation. The heating system creates temperature differences between your feet and the upper parts of the room.
A properly cared for underfloor heating electric system creates a uniform comfortable temperature that spans throughout your entire home. Stillorgan Gas provides system inspection services to fix heat distribution problems through specific repair methods.

Fact 2: Does Underfloor Heating Electric Use Less Energy Than Radiators?
Underfloor heating systems function at 30–40°C when operating properly but radiators require temperatures between comfort levels. The system requires additional energy to produce heat when it encounters problems with air traps or manifold 65–75°C.
The system operates at lower temperatures, which results in reduced energy usage while delivering equivalent blockages or faulty thermostats, which results in higher utility costs. Underfloor heating benefits from regular maintenance checks and repair services, which preserve its operational efficiency and increase its overall lifespan.

Radiators remain popular because they’re simple to install and repair. However, they require regular maintenance — bleeding, balancing, valve checks, and sometimes full power flushing — to prevent cold spots and efficiency loss.
By contrast, once a floor heating system is repaired and correctly balanced, it requires very little upkeep. It also promotes better indoor air quality by reducing convection and dust circulation, making it healthier for allergy sufferers.

The Dublin climate's dampness benefits from floor heating because it produces a constant heat flow which creates stable temperatures and minimizes cold air movement. Floor heating deliver superior comfort and operational efficiency when properly maintained and adjusted compared to traditional radiator systems.
