1. What This Underfloor Heating Guide Covers
If you’ve ever stepped onto a warm floor in the middle of winter, you already know how nice underfloor heating can feel. But for most homeowners, it’s still a bit of a mystery. How does it work? Is it expensive? Can you install it in an older home?
We’re Dublin Plumber 24 Hrs, a team of certified RGI gas installers with over 20 years of experience fitting plumbing and heating systems in homes across Dublin. We’ve put together this guide to help you understand underfloor heating from start to finish—so you can decide if it’s the right choice for your home.
We’ll keep things simple and practical. No jargon. Just straight answers based on the questions we hear from real people every week.
2. What Is Underfloor Heating and How Does It Work?
Underfloor heating is exactly what it sounds like—a heating system installed beneath your floors. Instead of using radiators to heat your rooms, it gently warms the entire floor surface. That heat rises evenly, making the whole space feel comfortable from the ground up.
There are two main types:
Electric underfloor heating: uses cables or mats to generate heat.
Water-based underfloor heating (also called hydronic): uses warm water flowing through pipes under the floor.
The idea is simple: spread heat out across the floor so you don’t need to crank up the thermostat. It’s more efficient, takes up no wall space, and keeps your feet warm on cold mornings.
At Dublin Plumber 24 Hrs, we install both systems and can help you figure out which is better for your home.
3. Types of Underfloor Heating
Not all underfloor heating systems are the same. Here’s a quick breakdown of the two types we work with most:
Electric Underfloor Heating
Best for smaller areas like bathrooms or single rooms.
Easier to install in existing homes.
Heats up quickly.
Slightly higher running costs compared to water systems.
Water-Based Underfloor Heating
Ideal for larger areas or whole-home setups.
Often used in new builds or major renovations.
Lower running costs in the long run.
Can be connected to your existing boiler or heat pump.
We usually recommend electric systems for retrofitting a small space and water-based systems for bigger projects. If you’re not sure what’s right for you, we’re happy to take a look and give you straightforward advice.
You can learn more about our underfloor heating installation services here.
Water-based systems are often paired with a heat pump to achieve the highest efficiency levels. If you’re planning a long-term heating upgrade, our heat pump services in Dublin can be installed alongside underfloor heating.
4. Is Underfloor Heating Right for Your Home?
We get asked this all the time. The good news? Underfloor heating works in most homes—but there are a few things to check first.
If you’re building a new home or doing a big renovation, it’s a perfect time to install it. You can lay the system during the build without much disruption. But even in older homes, it can still be a great option. We’ve installed it in apartments, terraced houses, and everything in between.
Here’s what we look at during a home visit:
Flooring type – Some floors (like tile or engineered wood) are ideal.
Insulation – Well-insulated homes hold the heat better and save you money.
Ceiling height – The system adds a small amount of height to your floor, which matters in some older properties.
Heating needs – Do you want to heat one room, the whole ground floor, or the entire house?
If you’re not sure if your home is suitable, we offer a free consultation to assess your space and give honest feedback.
5. Underfloor Heating Cost Dublin (2025 Guide)
The cost of underfloor heating depends on your floor size, the type of system you choose, and how much preparation work is needed. Here’s a realistic guideline based on typical Irish installer rates:
| System Type | Typical Installed Cost | Best For |
|---|---|---|
Electric Underfloor Heating |
€550 – €1,450 |
Bathrooms & single rooms |
Water-Based UFH (Hydronic) |
€2,450 – €6,950 |
Full ground floors & renovations |
Gas Underfloor Heating |
€3,950+ |
Whole-house heating linked to boiler |
Heat Pump + UFH Package |
€8,500+ |
High-efficiency A-rated homes |
💡These figures are based on publicly available pricing guidance from SEAI and typical Irish installer rates.
👉 Exact quotes vary based on property size, floor type, and insulation levels — we always provide a fixed written estimate before any installation begins.
Water-based systems work best when connected to a modern high-efficiency boiler or heat pump. If your existing unit is old, a gas boiler replacement in Dublin may be required as part of the upgrade.
6. The Installation Process – Step by Step
Wondering how long it takes or what the mess will be like? Here’s how we usually install underfloor heating, whether it’s a single room or the whole ground floor.
Step 1: Home Survey
We check your floors, insulation, and heating system. We’ll talk through the options and give you a full quote.
Step 2: Preparation
We remove the old flooring (if needed), lay insulation, and prep the area for the system. This is when the floor height might be adjusted slightly.
Step 3: Installing the System
Electric mats or water pipes are laid across the floor. For water systems, we connect the pipes to your boiler or heat pump.
Step 4: New Flooring
Once the system is tested, your flooring is installed on top. We’ll work with your flooring contractor or handle it ourselves—whichever you prefer.
Step 5: Final Checks & Thermostat Setup
We test everything, show you how to use your new thermostat (including smart options), and make sure the system runs as it should.
Depending on the size of the job, installation usually takes 1–5 days. We always try to keep disruption to a minimum.
If we find outdated or corroded pipework during the survey, we can carry out a full house replumbing in Dublin before installing the underfloor system, ensuring long-term reliability.
All gas connections are completed by our RGI-registered installers in line with Irish safety regulations.
7. Best Flooring Types for Underfloor Heating
Not all floors work equally well with underfloor heating. Choosing the right flooring makes a big difference in how efficiently your system heats your home.
Tiles and stone are the best options—they conduct heat quickly and hold it well. That means your floor heats up faster, and your energy bills stay lower.
Engineered wood can also work well, as long as it’s not too thick. Solid wood is a bit trickier because it can expand and contract with heat, so it needs to be carefully installed.
Avoid thick carpets or underlays that trap heat—they slow down how fast your floor warms and reduce efficiency.
If you’re planning new flooring, talk to us early in the process. We can recommend materials that work perfectly with your underfloor heating system.
8. Controlling Your System
One of the great benefits of underfloor heating is how easy it is to control. Most systems come with a thermostat, which lets you set the perfect temperature for each room.
We often install smart thermostats that connect to your phone or smart home devices. This means you can adjust your heating remotely or set schedules that match your daily routine—saving you money by only heating rooms when needed.
You can also set up zone heating, where different parts of your home heat independently. For example, you might keep the kitchen warm during the day but the bedrooms cooler until bedtime.
When we install your system, we’ll show you how to use all these features to get the most comfort and efficiency.
9. Maintenance and What Can Go Wrong
Good news—underfloor heating is low maintenance. Once installed, it usually runs quietly and reliably for years.
That said, it’s smart to keep an eye out for issues like uneven heating or unexpected cold spots. These can sometimes be signs of a problem with wiring (electric systems) or leaks (water systems).
We recommend a professional service check every few years, especially if your system is connected to your boiler. Our team at Dublin Plumber 24 Hrs offers full maintenance and repair services to keep your heating working at its best.
If you ever notice any problems or just want peace of mind, don’t hesitate to contact us—we’re available 24/7 for emergencies and regular service alike.

FAQs - Underfloor Heating
1. What is the average cost of installing underfloor heating in Ireland?
Underfloor heating installation costs in Ireland depend on the system, floor area and preparation required. Electric systems are generally cheaper to install in smaller spaces, while water-based systems usually cost more initially. In Dublin, our guide provides indicative electric system costs from €550 and water-based systems from €2,450. These are starting estimates, not fixed quotations, and the installation scope must be confirmed.
2. Is underfloor heating expensive to run?
Running costs depend on the system, insulation, floor area, thermostat settings and energy prices. Electric underfloor heating can be more expensive to run over large areas, while water-based systems may offer lower running costs when paired with an efficient heat source. Proper insulation and heating controls help manage energy consumption.
3. What is the downside of underfloor heating?
The main disadvantages are the initial installation cost, possible disruption to existing floors and slower heating response in some systems. Repairs can also be more complicated when pipes or heating cables are beneath the flooring. Choosing the right system and ensuring professional installation can reduce these problems.
4. Is underfloor heating really worth it?
Underfloor heating can be worthwhile for homeowners who want comfortable, even heating and more flexibility with room layouts. It is particularly attractive during renovations or when installing new floors. However, whether it is cost-effective depends on the property, insulation, installation costs and expected running expenses.
5. Is it cheaper to run radiators or underfloor heating?
Water-based underfloor heating can operate at lower water temperatures than traditional radiators, potentially improving efficiency with a suitable heating system. However, it is not always cheaper to run. Costs depend on insulation, heating controls, energy tariffs and the heat source. Electric underfloor heating may cost more to operate than a well-designed radiator system.
6. Can underfloor heating heat the whole house?
Yes. A properly designed water-based underfloor heating system can heat an entire home when the building’s heat-loss requirements are met. Electric underfloor heating is more commonly used in smaller areas, such as bathrooms and kitchens. The right choice depends on the property’s insulation, floor construction and heating requirements.
7. What are common problems with underfloor heating?
Common problems include uneven heating, thermostat faults, trapped air in water-based systems, circulation issues and inadequate insulation. Water-based systems can also experience leaks, although properly installed pipework is designed for long-term use. Professional assessment is recommended before attempting repairs.
8. What is the lifespan of underfloor heating?
Underfloor heating systems can last for decades when properly designed, installed and maintained. Water-based pipework may last 40–50 years or longer, depending on the materials and conditions. Thermostats, pumps, manifolds and other components may need replacement sooner. Actual lifespan varies by system and manufacturer.
9. Do I need to dig up the floor to install underfloor heating?
Not always. Some low-profile underfloor heating systems can be installed over suitable existing floors, although they may increase floor height. Other installations require removing existing flooring or preparing a new floor structure. The best approach depends on the property and chosen heating system.
10. Does underfloor heating installation come with a warranty?
Yes. Dublin Plumber 24hrs provides a 12-month workmanship warranty on eligible underfloor heating installation work. Manufacturer warranties on equipment and components may apply separately. Terms and conditions apply. Contact us for full warranty details and a free quotation.
