The choice
Hot Water Cylinders in Clare: Vented vs Unvented
The right cylinder for your Clare 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 Ennis, Shannon, Kilrush, Killaloe, Ennistymon, Lisdoonvarna, Kilkee and Scarriff. Sizing, mains pressure and safety all shape the right choice for your home.
How Long Does a Cylinder Replacement Take in Clare?
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 Clare 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 Clare: The Areas Covered
Clare is a predominantly rural county on the west coast with a relatively small natural gas network concentrated in Ennis and Shannon. The majority of the county lies outside the gas grid, making LPG the most common alternative fuel for homes and businesses in the rural west and north of the county. Installers operating across Clare therefore tend to see a mix of natural gas work in the main towns and LPG appliance and connection work in outlying areas.
Co. Clare has a diverse housing stock: Ennis and Shannon have substantial estates of 1980s-to-2000s housing; the Burren and west Clare coast have traditional stone cottages and rural farmhouses. Shannon Town has a high proportion of 1960s-70s housing built during the industrial development phase, which now needs significant boiler and cylinder upgrades.
West Clare is exposed to Atlantic storms with some of the highest wind speeds in the country. This makes outdoor pipe installations and roof-penetrating flues a priority for proper insulation and fixings. The Shannon Estuary creates mild winter temperatures for Shannon Town and Killaloe.
Ennis has well-established plumbing contractors covering much of the county. Shannon Town has dedicated local businesses. West Clare and the Burren coast are covered by travelling contractors from Ennis and Ennistymon, with response times reflecting the driving distances involved.
Every area above is served by local plumbers in the Clare plumber directory.
The options
Vented, Unvented or Twin-Coil in Clare
Ennis and Shannon are the main centres with natural gas coverage in Clare. Much of the county, including the Burren, West Clare and the coastal areas, relies on LPG or oil for heating.
Vented Cylinder
Fed by gravity from an attic tank and still the most common cylinder across Clare, from town terraces to older homes. The cheapest like-for-like swap. Supply and fit.
Heat-Pump / Solar Cylinder
A twin-coil cylinder pairs a solar or heat-pump coil with a boiler coil. Increasingly the standard replacement across Clare as more homes take up SEAI grant work.
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.

Clare draws from the River Fergus and Lough Derg as primary sources. West Clare coastal properties can have issues with salt-laden air accelerating corrosion on outdoor pipework and boiler flues. Groundwater in the Burren area is exceptionally hard due to the karst limestone, causing rapid scale build-up in heating systems.
SEAI grants
SEAI Grants for Clare 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 Clare are listed at wallinsulationireland.ie.

How to Find a Plumber for a Cylinder in Clare
A cylinder swap is standard plumbing work, but an unvented unit needs a competent installer. Here is how to hire correctly in Clare.
Browse Plumbers in Clare
Browse local plumbers in the Clare 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 Clare: Common Questions
How much does it cost to replace a hot water cylinder in Clare in 2026?
A like-for-like vented copper cylinder replacement costs €600 to €1,100 in Clare, 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 Clare?
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. Clare homes with power showers and multiple bathrooms usually benefit most from unvented.
What size hot water cylinder do I need for my Clare home?
Sizing follows the number of bathrooms and occupants rather than the county. A one or two-bathroom Clare 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 Clare?
An unvented cylinder delivers strong, balanced hot and cold pressure at every tap and shower in your Clare 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 Clare?
Most homes on the public mains in Clare 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 Clare?
