when you want water to boiled is it best to start with cold water to heat quicker?
Yes.. it is, if you start with hot water it requires less quantity of energy to be Boiled.
This doesnt relatively make you warmer, besides the undeniable fact that it makes your ideas think of you're. you purely say Ahh this water is so heat! It feels sturdy! Lol. whilst i pass surfing interior the morning, that what I do. Then my legs get numb, and you dont sense something anymore. and then, in case you concentration on something besdieds how chilly the water is, it might desire to help. per danger if your reallly reallllyyy warm previously, the water will sense sturdy!! Sorry this wasnt lots help! wish you win, you something (o:
the hot water from your faucet, if from a tank, will contain all sorts of crap, salts, metals, dead woodlice, etc, and it is not advisable to consume it directly, even if you boil it, as this will not alter any dodgy metal content, though it will likely kill any bugs growing in there, depending on the length of time you boil it for. for example, if you took some water from a pond and put it in the kettle, this would not be an adequate disinfection process in order to render it potable. but no, start out with hot water to boil it quicker, come on, its elementary
Hi there, Usually, if you want water heated, you should start out with cold water since this normally comes into your home via the mains supply, which should be clean, whereas the hot water will normally come from a boiler, which could have all sorts of nasties in it. However, If you are going to boil the water, then there is no harm in starting with hot water, as boiling should get rid of all the nasties, although i still wouldnt want to drink it... There is no advantage in starting with cold water in terms of it heating quicker though, I don't think there is such thing as a reverse Mpemba effect Cheers! :)
Mpfffff.... OK..... A modern *conventional* tank-type electric or gas water heater has a magnesium rod inside as an anti-corrosive/sacrificial electrode. These add minerals to the water which are not directly healthy to ingest. Further to this, hot water is more chemically active than cold water, and so in passing through your distribution pipes can pick up additional contaminants such as residual lead, antimony or arsenic from the solder, chemicals from any sealing agents, plain, ordinary rust, corrosion or copper salts from the pipes themselves and so forth. An instantaneous water heater with a copper heat-exchanger will be less prone to salting and contamination as the water is heated only for direct delivery (there is no storage) and there are no sacrificial electrodes in the system. A modern stainless-steel indirect water heater is somewhere between the two as there is storage, but no sacrificial electrodes. Start with cold water. It is simply healthier.
