Water heater installation and repair (especially electricity water heater) can have a significant risk of electrocution and death because water may come in contact with electricity. In Singapore, most of us are using electrical water heaters rather than gas and therefore precautionary measures have to be taken when installing the water heater.
Whether you’re buying and installing a new water heater, or whether replacing an old and broken water heater, it is always best to hire a professional licensed electrician to handle the water heater installation and repairs properly and safely.
When you are choosing a suitable water heater, it depends on:
- the size of your home;
- your family’s hot water needs; and
- your energy usage expectations.
Types of Water Heaters
There are many water heaters on the market, catering to all your needs and requirements.
Conventional Water Heaters
Conventional Water Heaters – Water is stored in a tank (available in different sizes) using gas or electric energy to maintain the set temperature. A conventional water heater lasts approximately 8-10 years. Newer models do offer better energy efficiency, with high-efficiency models offering up to 7% savings on your heating bill.
Tankless Water Heaters
Tankless Water Heaters – These heaters only heat water as needed. When you turn on the tap, the heater provides a continuous supply of hot water. While it saves on space (it can hang on a wall) it may require a larger upfront outlay due to additional electrical circuits, special venting, and larger gas lines. A tankless water heater can reduce your heating bill by up to 30% and has a life expectancy of up to 20 years.
Solar Water Heater
Solar Water Heater – Use sun energy to provide hot water. You can choose from an active or passive solar water heater system. The passive type is usually less expensive and more reliable than the active counterpart, but the active type is more efficient. Active solar water heaters have controls and pumps that circulate water into the home, but passive systems may last longer. Solar water heaters must have well-insulated storage tanks with backup for days when there is a high demand, or when it is cloudy.
Hybrid Heat Pump Water Heater
Hybrid Heat Pump Water Heater – This system combines a heat pump with a conventional storage tank. It extracts heat from the air, using existing electrical and water connections, and it can help reduce water heating costs by up to 60%.
Regular maintenance will help lengthen the lifespan of your water heater significantly.
Since installing a water heater requires work on both the water and the electrical wiring or gas supply of your home, it is always best to hire a professional electrician to do the installation. Not only does hiring a professional ensures that your water heater installation functions correctly and efficiently, but it also helps lower the risk of electrocution and fire hazard.
