These consist of a cylindrical vessel or container that keeps water continuously hot and ready to use. Typical sizes for household use range from 75–400 L (20–100 US gallons). These may use electricity, natural gas, propane, heating oil, solar, or other energy sources. Natural gas heaters are most popular in the US and most European countries, since the gas is often conveniently piped throughout cities and towns and currently is the cheapest to use.

A pressure reducing valve is sometimes employed to limit the pressure to a safe level for the vessel. Where hot-water space heating boilers are installed, domestic hot water cylinders are usually heated indirectly by primary water from the boiler, or by an electric immersion heater (often as backup to the boiler). Additionally, if these cylinders form part of a sealed system, providing mains-pressure hot water, they are known as unvented cylinders. Tankless water heaters—also called instantaneous, continuous flow, inline, flash, on-demand, or instant-on water heaters—are gaining in popularity.[citation needed] These high-power water heaters instantly heat water as it flows through the device, and do not retain any water internally except for what is in the heat exchanger coil. Copper heat exchangers are preferred in these units because of their high thermal conductivity and ease of fabrication.
