Pocy Hypersonic October 19, 2018 Share October 19, 2018 Actually, the storage heater is one way to get over water pressure issue. The storage tank is always placed overhead. Water is allowed to flow into the storage tank (regardless of flow rate/pressure), and the heater will get to work heating this water up. So the heated water coming out of your tank will always be at a consistent flow rate. That's why people installing rainshower will almost always use storage heater for the assured flowrate. Storage heater uses a mixer and water flow/pressure is regulated by the amount of cold water. Increase the pipe size may improve flow. ↡ Advertisement 1 Link to post Share on other sites More sharing options...
Lala81 Hypersonic October 20, 2018 Share October 20, 2018 The 2amp rating stated on the handphone charger refers to 5v DC power, it does not consume 2 amp on the 220v AC input source. The actual consumption on the wall plug is likely around 0.05amp only. thanks. physics not my strong suit Loose wire connection can cause ‘arching’ which produce a great amount of heat. This is how welding works - melt the metals and fused together. Fix electrical appliances and devices properly for safety. My friend once had arcing between wires near his circuit breaker. Could have been really serious from the photo i saw. Link to post Share on other sites More sharing options...
Ender Hypersonic October 20, 2018 Share October 20, 2018 thanks. physics not my strong suit My friend once had arcing between wires near his circuit breaker. Could have been really serious from the photo i saw. I think i had something similar for our circuit breaker. One night it tripped, cannot switched back on. Desperately called those 24 hr electrician. He removed the cover and part of the wall was blackened. 2 Link to post Share on other sites More sharing options...

Ct3833 Supersonic October 20, 2018 Share October 20, 2018 (edited) thanks. physics not my strong suit Haha bro, you dont say noboday knows but now we all know, it is not physics lah, it is electrical.Just joking, i am guessing the anwer also but i know it is certainly not 2 amp.

Jamesc Hypersonic October 20, 2018 Share October 20, 2018 Water heater better dun play play Better get approved heater from Singapore. There are few cases of water heater fatality. Ya lor. Mine too - both are Cornell bought in 2000. 1 was spoilt 2 years ago (16 years) n another still working. LOL Money a bit tight now I think I will just get the non approved one from JB for my MIL place. 3 Link to post Share on other sites More sharing options...
Jamesc Hypersonic October 20, 2018 Share October 20, 2018 Instant water heater ok for washing plates but for a shower better to get a storage heater. Storage heater has a higher pressure for a really good shower. I really cannot stand low water when showering and most importantly you switch it of before the shower so you won't get electrocuted.

Something like a total hard reset. Link to post Share on other sites More sharing options...
Kb27 Supersonic October 20, 2018 Share October 20, 2018 If sometimes your breaker trip, you can't push it back on, it means there's still a earth leakage or short somewhere. What you need to do is to unplug all your electrical devices, removed them totally from the socket. Then try to turn on your breaker. If it's successful, then start adding your devices/appliances one at a time. You'll find the culprit, the moment you plugged in and the breaker trips. 2 Link to post Share on other sites More sharing options...

When people have a problem they just want to switch on the circuit breaker. They have to find the root cause and solve that real problem. Cannot just reset the breaker as their is a leakage somewhere else and not solving that is very dangerous. Link to post Share on other sites More sharing options...
Happily1986 5th Gear October 20, 2018 Share October 20, 2018 anyway do these instant heaters really draw so much? I guess it's possible as those electrical cooking hobs can draw 20A. Like i mentioned, most electrical storage heaters locally are designed to be within the 13A limit of the normal plugs. FYI typical instant water heaters are rated between 3000W to 3500W by design. Current draw = 3000W / 220V = 13.6A 1 Link to post Share on other sites More sharing options...

My home circuit breaker trip last Tues when I was taking the electrical kettle off its stand to pour out the water. But I left everything on and it didn't trip again. Also no tripping since then. Was bit puzzled. Link to post Share on other sites More sharing options...

Was bit puzzled. If the breaker trips, it could be the insulation of the wires has degraded. Depending on how old is that wire, you might want to consider replacing it. Heating appliances carry a lot of current and heats up the wire and insulation. Long time ago, my fridge would trip the breaker. I've no clue what's happening, but my a/c colleague came, replaced the wire and all is well again. ELCB or RCCB works in 2 ways : 1. Overcurrent 2. Earth leakage Link to post Share on other sites More sharing options...

Seems quite OK since then. ↡ Advertisement Link to post Share on other sites More sharing options...
