Our Copper Cylinder range includes a wide range of sizes and both single coil and dual coil cylinders.
These have been developed to help reduce your home heating bill by ensuring optimum efficiency and therefore reducing energy use and costs.
Our copper cylinders include optimal insulation.
The Joule A1 copper cylinder range is Ireland's most advanced hot water storage cylinder on the market.
A typical house uses nearly 50% of its energy consumption on hot water production.
The Joule A1 range of copper hot water cylinders use advanced heat exchanger technology to reheat the entire cylinder in less than 20 minutes using a correctly sized boiler and pipework.
Reducing the heat up time of the hot water cylinder improves its efficiency by significantly reducing the amount of heat that the cylinder losses on an average day saving you money.
The A1 range of Joule copper cylinders employs a unique cold feed diffuser that improves the cylinder efficiency by up to 10% by allowing the hot and cold water to remain in layers up the cylinder based on the water temperature.
This reduces mixing and keeps hot water hotter.
The Joule A1 range of cylinders comes with industry leading insulation thickness levels.
This further helps to reduce heat loss and therefore reducing energy consumption on your boiler.
Some sizes are from LB Cylinders and these are just as efficient with the same high build quality.
All of these copper cylinders come with a 3/4“ tapping / pre installed shower outlet so suitable for a pumped shower system.

You can choose to also install an immersion heater and you can see the options for that here.
What is a single coil hot water cylinder?
A single coil hot water cylinder is the most common found in Irish homes and takes water from one source and heats the water in the cylinder.
The main heat sources in Ireland would be a oil or gas fired boiler.
If the boiler is not firing or is turned off then the water can still be heated if there is an immersion heater in place.
What is a dual coil hot water cylinder?
A dual could hot water cylinder is sometimes also known as a twin coil hot water cylinder and this is used when two methods of heating the water are used.
The most common instance of this in Ireland would be the use of solar panels to heat the water using the lower coil in the cylinder and the gas or oil boiler heating the water via the upper coil.
What can happen with the use of solar panels in Ireland is that on a gloomy or dull day then the solar panels might only heat a small proportion of the water that is needed.
When this happens then the gas or oil boiler will supplement that by heating the water via the upper coil.
Normally the lower coil is the one that has the first chance to heat the water and the upper coil will only be used if the water is not heated to the desired temperature.
A wood burning stove can also be used to heat the lower coil.
Do you also need pipe fittings?
The most common pipe fittings used with these cylinders are Compression 312 and Compression 317 brass pipe fittings.
The typical sizes utilised are 1" x 3/4" and 1" x 1".
We have a vast range of pipe fittings available so if you have any questions about these you can call us on 0818 888 000 and we will help in every way needed.
