Underfloor Heating in Limerick
Compare up to 4 underfloor heating professionals in Limerick. Free, no obligation.
Limerick city has a substantial stock of Georgian townhouses in the city centre (many in need of renovation), Victorian terraces in areas like the Ennis Road and South Circular Road, and large suburban estates from the 1970s to 2000s in Raheen, Dooradoyle, Castletroy, and Annacotty. Castletroy has seen significant development around the University of Limerick, with modern apartments and houses. Rural Limerick has traditional farmhouses and a steady stream of self-builds. The regeneration areas of Moyross and Southill have specific housing stock requiring upgrade programmes.
Limerick sits at the head of the Shannon estuary, receiving approximately 1,000mm of rainfall annually. The River Shannon and its tributaries create flood risk considerations in low-lying areas, particularly along the riverbanks and in older city-centre properties. The climate is milder than inland counties due to the Atlantic influence but wetter than the east coast. Prevailing south-westerly winds affect exposed properties. The relatively flat terrain means good solar exposure across most housing areas.

Limerick has seen significant regeneration investment and rising property values, making home improvements increasingly worthwhile. The presence of the University of Limerick and the technology and pharmaceutical sectors (Analog Devices, Cook Medical, Johnson and Johnson) drives rental demand and property upgrades. Limerick City and County Council has been proactive in supporting urban regeneration and energy upgrades. Contractor competition is healthy with pricing generally 10-15% below Dublin levels. The city's designation as European Capital of Culture has boosted civic pride and investment in property.

Underfloor Heating FAQs for Limerick
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.
