Benefits of Hot Water Cylinders in Your Home

Unvented Hot Water Cylinders

Hot water cylinders were only made legal around the world in 1986, but, since then have rapidly grown a reputation of note. In an unvented system there is no cold-water tank, instead the sealed hot water cylinder is fed right by the cold water mains. Since they are functioning at the mains pressure, they propose much better flow rates meaning your bath and shower performance should be higher.

The other key benefit is that you do not need to maintain a cold-water tank in the attic, which vented systems necessitate. This is noble news as not only does it free up space, it also eliminates the possible freezing issue during our long cold winter days.

Furthermore, since you are not trusting on gravity to move the hot water around the home, the unvented cylinder can be situated pretty much anywhere in your property. Other benefits of fitting an unvented system include reduced noise in the system since there is no cold water filling of the water storage reservoir, and since there is no water storage reservoir and the system is essentially closed, the cold water is not threatened by contamination.

Vented Hot Water Cylinders

Vented hot water tanks are still the most common type of hot water systems found in SA. Not like newer unvented tanks, these copper tanks are fed by cold water from a header tank (which can typically be located in the roof space) and they use gravity to drive the hot water throughout the home. A vent pipe links the vented hot water cylinder and the cold water in the header tank.

As with the unvented system, expansion of warm water is still a problem, but in this case the expansion simply takes place via the vent pipe and in the header tank. The hot water pressure tends to be ruled by the height of the water tank above the shower or tap feed, which means that although on the ground floor of the home the pressure might be brilliant; in rooms on the upper floors the pressure will be lower. As a result many showers in homes with vented hot water tanks use electric pumps to thrust the hot water to the shower with amplified pressure.

If you are in need of hot water cylinders and calorifiers then please take a look at Combustion & Heating Systems for more information. They can supply hot water cylinders of any size and capacity, horizontal or vertical, manufactured from stainless steel or mild steel, then either galvanized or lined. They can also supply either hot water or steam calorifiers.
