Hot Water Cylinder Replacement & Installation
Installation, replacement, and repair of hot water cylinders and immersion heaters.
What's Included in Our Cylinders Service
Why Your Hot Water Cylinder Matters
Your hot water cylinder is the heart of your domestic hot water system. Whether you rely on a copper cylinder, a modern stainless steel cylinder, or an indirect cylinder fed by your central heating boiler, keeping it in proper working order is essential for reliable hot water throughout your home. When cylinders fail, you are left without hot water for showers, baths, and daily tasks - and that is something no household in Athlone or the wider Midlands should have to put up with.
We provide a complete hot water cylinder service, covering everything from straightforward repairs to full cylinder replacement and new installations. Our work is clean, efficient, and built to last.
Our Hot Water Cylinder Services
Cylinder Replacement
Older cylinders can develop leaks, corrosion, or internal scaling that reduces their performance. If your cylinder is more than 15 years old, or you have noticed rusty water, inconsistent temperatures, or visible dripping, it is likely time for a replacement. We remove and dispose of your old unit and fit a new copper cylinder or stainless steel cylinder that matches your household demand and existing pipework layout.
New Cylinder Installation
Building an extension, converting a loft, or upgrading your heating system? A new hot water cylinder installation ensures you have enough stored hot water for your growing needs. We size the cylinder correctly based on the number of bathrooms, bedrooms, and occupants so you never run short. We also advise on whether a direct or indirect cylinder best suits your boiler type and heating setup.
Immersion Heater Repair and Replacement
The immersion heater is the electric backup element inside your cylinder. When it fails, you lose the ability to heat water independently of your boiler. Common faults include a burned-out element, a faulty thermostat, or a tripped safety cut-out. We diagnose the issue quickly and carry replacement immersion heater elements and thermostats on our van for same-day repair in most cases.
Thermostat Replacement
A faulty thermostat can cause water that is too hot, too cold, or fluctuating wildly. We test and replace cylinder thermostats to restore accurate temperature control. Correct thermostat settings also help reduce energy bills by preventing your system from overheating water unnecessarily.
Lagging and Insulation
An unlagged or poorly insulated cylinder loses heat rapidly, wasting energy and costing you money. We fit proper cylinder lagging jackets and insulate connecting pipework to keep your stored water hotter for longer. This is one of the simplest and most cost-effective improvements you can make to your home heating system.
Understanding Your Cylinder Type
Indirect Cylinders
An indirect cylinder is heated by a coil connected to your central heating boiler. Hot water from the boiler flows through the coil and transfers heat to the stored water in the cylinder. This is the most common arrangement in Irish homes with oil or gas boilers. It allows the boiler to heat both your radiators and your hot water.
Direct Cylinders
A direct cylinder relies entirely on one or two immersion heater elements to heat the water electrically. These are typically found in homes without a central heating boiler or as a simpler setup in smaller properties.
Expansion Vessels and Safety
Modern sealed heating systems use an expansion vessel to accommodate the increase in water volume as it heats up. We check the expansion vessel pressure during every cylinder installation to ensure the system operates safely and efficiently. We also inspect and replace the anode rod where fitted - this sacrificial component protects the interior of your cylinder from corrosion, extending its working life significantly.
Signs You Need Cylinder Attention
- No hot water or slow recovery - the cylinder is not heating properly or the immersion heater has failed.
- Discoloured or rusty water - internal corrosion has taken hold and the cylinder may need replacing.
- Leaking from the base or fittings - a sign of internal failure or deteriorated seals.
- Excessive noise - limescale build-up on the immersion heater element or internal scaling.
- High energy bills - poor insulation or a faulty thermostat forcing the system to work overtime.
