When the electricity is turned on, it directly heats up the water that passes through it, just before it comes out of your shower head. As long as it remains turned on, you will get continuous hot water without running out. It does not have any water tank to store hot water for later use. That&#8217;s why it&#8217;s sometimes called a tankless water heater.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Instant water heaters started gaining popularity in the 1990s. Before that, most households invested in storage water heaters.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1000\" height=\"667\" src=\"https:\/\/www.recommend.my\/blog\/wp-content\/uploads\/2021\/03\/instant-water-heater-malaysia1-1000x667.jpg\" alt=\"\" class=\"wp-image-22476\" srcset=\"https:\/\/www.recommend.my\/blog\/wp-content\/uploads\/2021\/03\/instant-water-heater-malaysia1-1000x667.jpg 1000w, https:\/\/www.recommend.my\/blog\/wp-content\/uploads\/2021\/03\/instant-water-heater-malaysia1-450x300.jpg 450w, https:\/\/www.recommend.my\/blog\/wp-content\/uploads\/2021\/03\/instant-water-heater-malaysia1-218x145.jpg 218w, https:\/\/www.recommend.my\/blog\/wp-content\/uploads\/2021\/03\/instant-water-heater-malaysia1.jpg 1200w\" sizes=\"auto, (max-width: 1000px) 100vw, 1000px\" \/><figcaption>Above: Instant water heater installed inside shower area in bathroom<\/figcaption><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">An instant water heater is just one type of water heater found in Malaysian households. The others are storage water heaters, gas water heaters, and solar water heaters.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Storage water heaters<\/strong> existed before instant water heaters, and come with a water tank, usually holding 25 to 80 litres of hot water. When the electricity is turned on, it will heat up the water in the tank, just like a kettle. You can adjust the setting to heat the water to as high as 75 degrees Celsius. Because these are much larger and heavier than instant water heaters, they are usually mounted away from the shower area, or hidden in the false ceiling or attic.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1000\" height=\"667\" src=\"https:\/\/www.recommend.my\/blog\/wp-content\/uploads\/2021\/03\/storage-water-heater1-1000x667.jpg\" alt=\"\" class=\"wp-image-22477\" srcset=\"https:\/\/www.recommend.my\/blog\/wp-content\/uploads\/2021\/03\/storage-water-heater1-1000x667.jpg 1000w, https:\/\/www.recommend.my\/blog\/wp-content\/uploads\/2021\/03\/storage-water-heater1-450x300.jpg 450w, https:\/\/www.recommend.my\/blog\/wp-content\/uploads\/2021\/03\/storage-water-heater1-218x145.jpg 218w, https:\/\/www.recommend.my\/blog\/wp-content\/uploads\/2021\/03\/storage-water-heater1.jpg 1200w\" sizes=\"auto, (max-width: 1000px) 100vw, 1000px\" \/><figcaption>Above: Storage water heater.

Therefore, you will need to connect it to a gas supply. When the temperature drops below the desired range, a small flame will be lit to heat up the water in the tank. Gas models are not as common in Malaysian households but are popular in laundromats to provide hot water for washing machines at lower running costs.<\/p>\n\n\n\n<figure class=\"wp-block-image size-medium\"><img loading=\"lazy\" decoding=\"async\" width=\"452\" height=\"300\" src=\"https:\/\/www.recommend.my\/blog\/wp-content\/uploads\/2021\/03\/gas-water-heater-malaysia-452x300.jpg\" alt=\"\" class=\"wp-image-22478\" srcset=\"https:\/\/www.recommend.my\/blog\/wp-content\/uploads\/2021\/03\/gas-water-heater-malaysia-452x300.jpg 452w, https:\/\/www.recommend.my\/blog\/wp-content\/uploads\/2021\/03\/gas-water-heater-malaysia-1000x664.jpg 1000w, https:\/\/www.recommend.my\/blog\/wp-content\/uploads\/2021\/03\/gas-water-heater-malaysia-218x145.jpg 218w, https:\/\/www.recommend.my\/blog\/wp-content\/uploads\/2021\/03\/gas-water-heater-malaysia.jpg 1200w\" sizes=\"auto, (max-width: 452px) 100vw, 452px\" \/><figcaption>Above: Gas water heater.

Instead, cold water is pumped into solar collector panels on your roof. These panels become very hot as they are exposed to the sun. As the cold water flows through the panels, they heat up as well. The hot water is then stored and ready for later use.<\/p>\n\n\n\n<figure class=\"wp-block-image size-medium\"><img loading=\"lazy\" decoding=\"async\" width=\"450\" height=\"300\" src=\"https:\/\/www.recommend.my\/blog\/wp-content\/uploads\/2021\/03\/solar-water-heater-malaysia-450x300.jpg\" alt=\"\" class=\"wp-image-22479\" srcset=\"https:\/\/www.recommend.my\/blog\/wp-content\/uploads\/2021\/03\/solar-water-heater-malaysia-450x300.jpg 450w, https:\/\/www.recommend.my\/blog\/wp-content\/uploads\/2021\/03\/solar-water-heater-malaysia-1000x667.jpg 1000w, https:\/\/www.recommend.my\/blog\/wp-content\/uploads\/2021\/03\/solar-water-heater-malaysia-218x145.jpg 218w, https:\/\/www.recommend.my\/blog\/wp-content\/uploads\/2021\/03\/solar-water-heater-malaysia.jpg 1200w\" sizes=\"auto, (max-width: 450px) 100vw, 450px\" \/><figcaption>Above: Solar water heater mounted on rooftop<\/figcaption><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">In Malaysia, instant and storage water heaters are by far the most popular types used in residential properties.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Why_choose_an_instant_water_heater_instead_of_a_storage_water_heater\"><\/span>Why choose an instant water heater instead of a storage water heater?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Ease of installation and cost-savings are the main reasons to choose an instant water heater over a storage water heater.

After many years, your storage water tank may start to leak due to corrosion or cracking. And that leak will end up all over your ceiling, causing huge amounts of damage. Just imagine a large amount of water being emptied into your attic!<\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"Storage water heater tank cracked and leaking into ceiling\" width=\"500\" height=\"281\" src=\"https:\/\/www.youtube.com\/embed\/yYux-7hVKG0?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n<\/div><figcaption>Above: What could happen if your storage water heater ruptured and dumped all its contents into your false ceiling<\/figcaption><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_features_should_I_look_for_in_an_instant_water_heater\"><\/span>What features should I look for in an instant water heater?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">When shopping for your next instant water heater, look for these essential features. They should be basic features in every single model:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li><strong>Splash proof casing<\/strong>. To prevent water from getting into the circuits. It should be rated as IP25 standard.<\/li><li><strong>Circuit breaker<\/strong>. Circuit breakers will cut the power within 0.1 seconds if it detects an electrical leakage<\/li><li><strong>Rust-free heating elements<\/strong>. This prevents a buildup of rust or sediment which could catch fire<\/li><li><strong>Surge protection<\/strong>. Protects from lightning strikes and current leakage<\/li><li><strong>Flow sensor<\/strong>. Enables the heater to keep working even in low water pressure. At the same time, it also shuts off the heater if the water flow is too low, to prevent overheating<\/li><li><strong>Non conductive hose<\/strong>. Since 2000, instant water heaters in Malaysia must come with non-conductive hoses. Before this, older models may have used stainless steel hoses; an electrocution hazard<\/li><li><strong>Thermostat cut-off<\/strong>. Cuts the power in case the temperature goes above 75 degrees Celsius, to prevent scalding<\/li><\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">As today&#8217;s water heaters keep getting better, you should also be aware of these new and improved features for better flow rate, energy efficiency, safety and more.<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li><strong>Improved circuit breakers (RCD or RCCB)<\/strong>. Older models used a circuit breaker called an ELCB (earth leakage circuit breaker). However, newer models use a better version called a residual current device (RCD) or residual current circuit breaker (RCCB), which are much better at detecting electrical faults. Your home&#8217;s electrical fuse box already contains an RCCB, but it&#8217;s worth getting a heater that has its own built-in as well. Models that have this include the <a href=\"https:\/\/www.onsen.my\/collections\/centon-shower-water-heater\/products\/centon-vintage-series\" target=\"_blank\" rel=\"noreferrer noopener\">CENTON Vintage Series<\/a> and <a href=\"https:\/\/www.onsen.my\/collections\/centon-shower-water-heater\/products\/centon-serene-series\" target=\"_blank\" rel=\"noreferrer noopener\">Serene Series<\/a>.<\/li><\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Should_I_get_a_water_heater_with_or_without_a_pump\"><\/span>Should I get a water heater with or without a pump?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Nobody likes a dribbling shower. Some properties, such as low-level condo units, or landed properties may suffer from low water pressure.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If your house water pressure already feels low, remember that it may become even lower after going through an instant water heater. That&#8217;s because the water needs to flow through the heat exchanger, unlike in a storage water heater, where the water is already pre-heated, and just flows directly to your showerhead.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">To counter this effect, many instant shower heaters come with a built-in pump to force more water through the showerhead. There are two types of pumps in instant water heaters:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li><strong>Instant water heater with AC pump<\/strong>. Adds much more water pressure. Suitable if you want a rain shower that delivers a lot of water at once. But, AC pumps are noisy when in use.<\/li><li><strong>Instant water heater with DC pump<\/strong>. Adds less water pressure compared to AC pumps. Suitable to increase water pressure in a normal showerhead. DC pumps are much quieter and usually more efficient compared to AC pumps.<\/li><\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">An instant water heater with a pump may double the cost of the unit.
