by Types of geyser
There are three main types of geysers: gas geysers, electric geysers, and heat pump geysers. Each has its own benefits depending on your needs and home layout.
Gas geysers are one of the most common and affordable options. They use natural gas or propane as the fuel source to heat water. Gas geysers typically have higher recovery rates than electric models, meaning they can re-heat water faster. However, they do require a gas supply line and flue to vent combustion gases outdoors.
Electric geysers operate using electricity as the sole power source. They are generally less expensive to install since no gas lines are needed. However, they tend to have higher operating costs compared to gas models. Electric geysers are also limited by the recovery rate of the heating elements.
Heat pump geysers harness the energy from the air to heat water efficiently. They work like a refrigerator in reverse by transferring heat from the outside air to the water. Though more expensive up front, heat pump geysers can save significantly on utility costs over time thanks to their energy efficiency. However, they require air flow clearance and only work well in moderate climates.
Capacity and Efficiency
The primary factors that influence geyser capacity are storage tank size and recovery rate. Larger tank sizes allow for more stored hot water but take up more space.
Tankless or on-demand geysers heat water only as it’s needed rather than storing it. This saves energy but provides a lower continuous flow than a storage tank model.
Energy efficiency is rated by the unit’s Energy Factor (EF). The higher the EF, the more efficient the geyser is at turning power into heated water. Newer, better insulated models can have EFs over 0.90. Regular maintenance like flushing sediment and adjusting thermostats helps older units run more efficiently too.
Additional Features
Many modern Water Heater now include additional features for convenience and safety:
– Timer/circulation pumps keep hot water circulating to taps for instant use.
– Self-modulating burners on gas units adjust flames based on demand for optimal efficiency.
-Rheostats allow adjusting the thermostat for desired temperature without tools.
-Anode rods protect against corrosion but need periodic inspection/replacement.
-Vacuum relief valves automatically release air to maintain pressure.
-Extended warranties (6-12 years) cover tanks and parts for extra coverage.
Installation and Placement
Proper installation is critical for safety, performance and code compliance. Water heaters are typically placed in a utility room, closet or garage near the points of use. Clearances around gas units ensure sufficient ventilation.
All plumbing connections must meet local code including TPR (temperature pressure relief) valves directing discharge away from living areas. Gas lines require shut-off valves for maintenance. Unobstructed access is needed for repairs or flushing out sediment over time. Elevating units off the floor shelters from flooding and makes work easier.
Maintenance and Lifespan
Most water heater last 8-12 years on average with proper care and maintenance. Gas units may need occasional cleaning of burners/pilot assemblies and checking for exhaust leaks. Sediment build-up decreases efficiency and damages elements over time, so annual flushing helps extend the life. Check anodes routinely too – once they’re heavily depleted, premature failure could result without replacement.
Always turn off power or gas supply and relieve pressure before servicing any components. Resetting thermostats or replacing parts may also be necessary during the usable lifespan. With regular maintenance according to manufacturer guidelines, geysers can operate dependably for many years.
In summary, understanding your geyser options, features, placement and maintenance needs allows you to get the most from this crucial home appliance. Proper selection, installation and care will deliver hot water safely and cost-effectively.
