Vented Cylinders

Vented Cylinders

Vented water cylinders are the most traditional type of cylinder, and they require a cold water tank usually located in the loft space. The water in the cylinder is heated by an external heat source, typically a boiler or immersion heater, and the hot water is drawn off from the top of the tank. Vented models are simple and inexpensive, but they are not suitable for homes with low water pressure, as the water flow rate depends on the height of the tank above the taps.

Our models typically have a capacity of around 100-150 litres and are made of stainless steel, copper, or enamel-coated steel. They come in a range of sizes to suit different heating and hot water requirements, and can be installed in a variety of locations, such as a loft, cupboard, or basement such as the Gledhill Envirofoam Copper.

One of the main benefits is their simplicity. They do not require a pump or expansion vessel, as the vent pipe provides the necessary pressure regulation. This makes them relatively low-maintenance and easy to install. However, it is important to note that vented water cylinders are not as energy efficient as unvented systems, as some of the heat is lost through the vent pipe. Additionally, the vent pipe must be installed correctly and maintained regularly to prevent leaks and other issues.
