Underfloor Heating in Dublin
Compare up to 4 underfloor heating professionals in Dublin. Free, no obligation.
Dublin's housing stock is Ireland's most diverse, spanning from Georgian terraces in the city centre (1750s-1830s) through Victorian and Edwardian suburbs (1840s-1910s), inter-war and post-war council housing (1930s-60s), suburban estates (1960s-2000s), Celtic Tiger apartments (1998-2008), and modern high-density developments. Each era presents distinct characteristics for home service providers: Georgian homes have solid brick walls, original timber floors, and sash windows. 1960s-70s suburban semis have cavity block walls, often with minimal insulation, and are the most common candidate for energy retrofits. Celtic Tiger-era apartments may have building defects from the construction boom. The sheer density and variety of Dublin housing means every type of home service has strong, consistent demand.
Dublin has a temperate maritime climate with relatively low rainfall by Irish standards (approximately 750mm annually), though this still exceeds most UK and continental European cities. The east-facing position means less rain than the west coast but more exposure to cold easterly winds in winter, which can affect heating demand and frost risk. Sea proximity moderates temperature extremes. South-facing properties benefit from good solar exposure, making Dublin viable for solar PV installations. Urban heat island effects mean the city centre is typically 1 to 2 degrees warmer than outer suburbs.

Dublin is Ireland's busiest market for all home services due to population density and property values. High demand means competitive pricing for standard trades but premium rates for specialist services. Property values drive significant investment in home improvements, with homeowners willing to spend more on quality materials and finishes. The four Dublin local authorities (City, Dun Laoghaire-Rathdown, Fingal, South Dublin) each have distinct planning approaches. Conservation areas are extensive in Dublin city centre, Dun Laoghaire, and parts of Fingal. Dublin prices for home services are typically 15 to 25% above the national average, reflecting higher labour costs, travel time, and material delivery costs in the urban environment.
Underfloor Heating Costs in Dublin
Typical costs for underfloor heating in Dublin (prices may vary (typically 50% above national average)):
| Service | Typical Cost | Notes |
|---|---|---|
| Electric UFH (per sq m) | €75 | €120 | Area, thermostat |
| Wet UFH (per sq m) | €120 | €195 | System design, manifold |

Underfloor Heating FAQs for Dublin
Wet underfloor heating in a new build or extension costs €40 to €70 per square metre for supply and installation, where the screed is being poured anyway. Retrofit wet systems cost €60 to €100 per sq m due to additional floor preparation. Electric mat systems cost €30 to €60 per sq m. A bathroom electric mat costs €500 to €1,200 installed. A whole-house wet system in a 150 sq m new build costs €7,000 to €12,000 including manifold, pipes, and controls.
Yes, particularly when paired with a heat pump. Underfloor heating operates at water temperatures of 30 to 40 degrees, which matches the output of heat pumps perfectly, allowing both systems to run at peak efficiency. This combination is one of the most energy-efficient heating solutions available in Ireland today. Even with a conventional boiler, underfloor heating distributes warmth more evenly than radiators, which often means you can run the thermostat 1 to 2 degrees lower for the same perceived comfort.
It is possible but more complex and expensive than in a new build. Options include laying a low-profile wet system on top of the existing floor (raising the floor level by 30 to 50mm), excavating the existing floor to accommodate standard pipes beneath a new screed, or installing electric mats in individual rooms like bathrooms and kitchens. The practicality depends on your existing floor construction, ceiling height in the room below, and your willingness to accept a slightly raised floor level.
Tile (porcelain, ceramic, natural stone) is the best conductor of heat and the ideal partner. LVT and engineered wood are also fully compatible, with engineered wood performing best at thicknesses up to 18mm. Thick carpet with dense underlay (above 1.5 tog combined) insulates against the heat and significantly reduces the system's effectiveness. Solid hardwood is generally not recommended due to the risk of shrinkage, warping, and gaps developing over time from the constant heat below.
Underfloor heating is a slow-response system compared to radiators. A wet system embedded in screed takes 2 to 4 hours to bring a cold room up to temperature. Once the screed is warm, its thermal mass maintains a stable temperature with minimal additional energy. Electric mat systems beneath tiles respond faster, typically 30 to 60 minutes. The key is to programme the system with longer lead times rather than switching it on and off throughout the day.
Yes, this is very common in Irish homes. Many use underfloor heating in the ground floor extension or kitchen-living area and radiators upstairs. Both can run from the same boiler or heat pump, but the system must be designed with separate flow temperatures because underfloor heating runs cooler (30-40 degrees) than radiators (55-70 degrees). A mixing valve or buffer tank manages these different temperature requirements within one system.
