Types of Water Heating

There are many energy sources but only two types of water heaters. These include electricity, gas (ULPG or Natural) and renewable energy sources such as the sun, wind, wood and even pellet type fuel sources. What’s more you can combine energy sources for incredibly efficient and sustainable water heating solutions. Water heaters fit into two categories – storage and continuous flow. There are many ways to heat your water and here at Rheem we are dedicated to bringing you the right solution for the needs of your home and family

Storage Water Heaters

These are the well known upright cylinders in our homes which are generally heated by electricity or gas. Suitable for mains pressure or low pressure.

Mains pressure Storage

Mains Pressure systems deliver full flow and allow for a wider range of modern fittings. Tank or bore water can also be pumped to mains pressure. If you are living in a residential area you will almost certainly have mains pressure available at your gate.

Low Pressure Storage

Low Pressure water heaters are a common sight in older homes and while they are typically electric, some gas systems do exist. Rheem has a large range of low pressure copper and vitreous enamel (VE) lined cylinders. The VE cylinders can provide more pressure and copes better with a wider range of problematic water types such as high chlorination.


Heat pumps are the most advanced and efficient water heating option currently available. Heat is extracted from the surrounding air and converted into energy which is then used to heat the stored water.


Solar captures free energy from the sun using roof-mounted panels (collectors), this energy is then transferred to a storage cylinder. This can be paired with electric, gas storage or gas continuous flow for a reliable and energy efficient hot water system.
