The choice
Hot Water Cylinders in Longford: Vented vs Unvented
The right cylinder for your Longford home comes down to how it is plumbed. A vented copper cylinder is fed by gravity from a tank in the attic and is the traditional Irish setup. An unvented cylinder runs at mains pressure for stronger showers with no loft tank, but it stores water under pressure and needs a competent installer with the correct discharge pipe and safety controls.
The plumbers listed here cover the whole county, taking in Longford town, Granard, Edgeworthstown, Lanesborough, Ballymahon and Kenagh. Sizing, mains pressure and safety all shape the right choice for your home.
How Long Does a Cylinder Replacement Take in Longford?
A like-for-like vented swap takes a few hours to half a day. An unvented conversion or a relocation takes a full working day.
SEAI Grants for Longford Homeowners in 2026
Up to €1,200 for solar water heating and €6,500 for a heat pump, both of which need a compatible twin-coil cylinder.
Local coverage
Hot Water Cylinders Across Longford: The Areas Covered
Longford is a small midlands county with a largely rural population centred on Longford town. Natural gas network coverage in Longford is limited to the county town and a small number of other locations, with the majority of the county relying on oil and LPG for heating. The pool of RGI registered gas installers in Longford is relatively small, and homeowners in more remote parts of the county may need to source an installer from a neighbouring area.
Longford is a small Midlands county with a dispersed rural housing pattern and a single main town. The housing stock is predominantly older, with a high proportion of oil-heated bungalows and farmhouses. SEAI heat pump conversion has been gaining traction as a route to reducing oil dependency, and the county has a reasonable number of SEAI-registered contractors.
Longford is inland and flat, with minimal shelter from northerly and north-westerly winds. Cold snaps can be prolonged, and the Midlands frost record is well above the national average. Lanesborough, on the Shannon, benefits from some winter temperature moderation near the river.
Longford Town has the main concentration of plumbing contractors serving the county. Granard has some local coverage for north Longford. Ballymahon and Lanesborough in the south often draw from Longford Town or Athlone-based contractors.
Every area above is served by local plumbers in the Longford plumber directory.
The options
Vented, Twin-Coil or Mains-Pressure for Longford Homes
Longford town has access to the natural gas network. The wider county, including Granard, Edgeworthstown, Lanesborough and rural areas, relies predominantly on oil or LPG.
Vented Cylinder
The default in older Longford cottages and farmhouses, fed by gravity from a tank in the attic. Reliable and the cheapest cylinder to replace like for like. Supply and fit.
Heat-Pump / Solar Cylinder
The go-to upgrade across rural Longford, where solar thermal and heat pumps are common. A twin-coil cylinder stores heat from the renewable source and a boiler or immersion backup.
Unvented (Mains-Pressure) Cylinder
Runs straight off the mains for strong, balanced pressure at every tap and shower, with no attic tank. Stores water under pressure, so it needs a competent installer.

SEAI grants
SEAI Grants for Longford Water Heating Upgrades
Grants are available for solar water heating (up to €1,200) and heat pump installation (up to €6,500). Both need a compatible twin-coil cylinder, so a cylinder upgrade is often the first step, and work must be carried out by an SEAI-registered contractor before any grant can be claimed. A fabric-first upgrade makes the biggest difference to running costs, and SEAI-registered insulation contractors covering Longford are listed at wallinsulationireland.ie.

How to Find a Plumber for a Cylinder in Longford
A cylinder swap is standard plumbing work, but an unvented unit needs a competent installer. Here is how to hire correctly in Longford.
Browse Plumbers in Longford
Browse local plumbers in the Longford plumber directory, find someone near you, and contact them directly. For an unvented cylinder, check that they hold the relevant competency, as mains-pressure units carry discharge and safety requirements.
Get Three Written Quotes for the Work
Quotes should name the cylinder make, its capacity in litres, whether it is single or twin coil, and any pipework, controls or discharge work needed. A quote without a stated capacity is incomplete, since sizing drives both comfort and the price you pay.
Confirm SEAI Registration if Claiming a Grant
A compatible twin-coil cylinder is part of any solar water heating or heat pump job. Where a grant is involved, the wider works must be carried out by an SEAI-registered contractor, so confirm registration before the cylinder is ordered.
Get Your Commissioning Paperwork and Warranty
An unvented cylinder must be commissioned with its discharge pipe, expansion vessel and safety valves set correctly. Keep the commissioning record and register the warranty, as most manufacturers require an annual check to keep cover in place.
Hot Water Cylinders in Longford: Common Questions
How much does it cost to replace a hot water cylinder in Longford in 2026?
A like-for-like vented copper cylinder replacement costs €600 to €1,100 in Longford, including labour and VAT at 9%. A full unvented mains-pressure install runs €1,200 to €2,200, upsizing or relocation is €900 to €1,600, and an immersion element and thermostat is €150 to €300.
Vented or unvented cylinder: which is better in Longford?
A vented cylinder is cheaper and simpler where a loft tank already feeds the house, but pressure depends on the height of that tank. An unvented cylinder gives mains pressure at every outlet with no attic tank, at a higher price and with stricter safety requirements. Longford homes with power showers and multiple bathrooms usually benefit most from unvented.
What size hot water cylinder do I need for my Longford home?
Sizing follows the number of bathrooms and occupants rather than the county. A one or two-bathroom Longford family home is typically well served by a 150 to 210 litre cylinder, while larger homes with several bathrooms move to 250 to 300 litres. Your plumber sizes the cylinder to peak demand so you are not left short or heating water you never use.
What are the benefits of a mains-pressure unvented cylinder in Longford?
An unvented cylinder delivers strong, balanced hot and cold pressure at every tap and shower in your Longford home, removes the need for an attic tank, frees up loft space and cuts the risk of tank freezing or contamination. The trade-off is a higher fit cost and a required annual safety check.
Is there enough mains pressure for an unvented cylinder in Longford?
Most homes on the public mains in Longford have enough flow for an unvented cylinder, but rural properties on a private well or a shared group scheme may not. Your plumber checks the incoming flow and pressure first, and where the mains is weak a vented cylinder or a pumped system is the better fit.
How do I find a plumber for a cylinder in Longford?
Browse local plumbers across Longford on plumbersinireland.ie and request quotes directly. For an unvented cylinder, confirm the plumber holds the relevant competency, as mains-pressure units carry discharge and safety requirements that a standard vented swap does not.
