Hot water cylinders in Clare
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.
The options
Vented, Unvented or Twin-Coil in Clare
The right cylinder depends on your mains pressure, hot water demand and whether there is space for a tank.
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.
from€600
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.
from€900
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.
from€1,200

- Get quotes that name the cylinder make, litre size and grade
- A failed immersion element alone is €150 to €300, not a full swap
- Changing to unvented adds mains checks and a discharge route
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.
- Cylinder replacement €600–1,100
- Unvented mains-pressure install €1,200–2,200
- Upsizing or relocation €900–1,600
- Immersion element and thermostat €150–300
- Annual check €70–110
Indicative 2026 ranges. Always confirm with a written quote before work begins.
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 €12,500). 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 across Clare, 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.

Common questions
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. 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.
