We are using our gas range to heat our house during the day, because we are cooking and canning all day, anyway.
during the intermittent times that we are not actively cooking or canning something we leave a kettle of boiling water on the burner. isn't that more thermally efficient to heat the house than just the burner being on, by itself, with no thermal mass (boiling water) on it?
I'd say it is more efficient because it forces some of the heat to stay in water (which has a very high specific heat and retains a lot of energy per degree of temperature change) as opposed to heating only air directly. It really depends on the overall ability of your house to prevent heat loss to the outside (ie how well insulated it is). If you have a leaky house the radiant heat from the water would likely be more efficient as heat energy moves from hot to cold and all that hot air would leave the house while the water would be giving off energy more slowly and consistently (house would be a lower average temperature). If your house is well insulated it wouldnt really matter because it would all get stuck inside.
>We are using our gas range to heat our house during the day
Do NOT use a gas stove for heat. Stoves are not vented, so you are exposing yourself to combustion gases like carbon monoxide and aldehydes. Gas burners lower the oxygen level in the house the longer they are on.
Quit being a moron and get some electric space heaters if you're too cheap to run the furnace.
Wow, thanks for your input even though you have exactly zero understanding of the subject.
No but you're wasting heat that you paid for.
Frick off with your meme heater bullshit
The water also adds needed humidity to the air. The higher the humidity, the more comfortable you feel at a lower temp. For example, 66 degrees and 10% RH isn't nearly as comfortable as 66 degrees and 35% RH.
It's not really lost, you simply consume less gas because you're not superheating the water.
Oh look, it's the "I'm gonna come through an old thread and set multiple people straight one by one like a badass in a kung fu movie, but with brusque insults instead of fists, that illustrate that I'm a busy guy with better things to do but someone needs to be the parent/cop who brooks no nonsense and sets everyone straight for their own good and you're lucky I deigned to make this one post because I'm the smartest guy in the room" guy.
You sound upset. You wanna talk about it?
>than just the burner being on, by itself,
In every manual for every stove I have ever seen, it is contraindicated to use the stove as a heater. You are probably better off leaving something on it like water. You get the benefit of increased indoor humidity in the winter, too.
my dad lived in an apartment for 15 years, he heated it in the winter by turning the oven on, opening the door and cracking a window.
not saying it was right.
>thermally efficient
Your system isn't terribly well defined, so figuring out its efficiency is quite difficult.
I suspect, though, is what you're really asking is: what's the most efficient way to heat my home's air using a range burner?
In which case, don't use water.
The watts you produce will disappear into the phase transition of water into water vapor. That's not warming your air or you.
Just burning into the air, i.e. with nothing is literally heating the air, but you're not going to "feel" that much since it goes straight up and has to convect around and make the ambient temperature higher.
If you want to "feel" warmer: use a couple fire brick or a pizza stone or some such on the burner. And blow a fan over it.
This will act as a nice, even repository for the heat. Provide radiant heat. And actually make your life a bit easier, because if you want to boil some water or something after the stone is heat saturated, just put your kettle on the stone.
This anon gets it; one of the best heat radiators for this kind of heating is a 10" dia. terra cotta flower pot set upside down on a grate over a gas burner. The tapered shape causes heat to be focused and heats the material quickly, and also radiates it out evenly. It doesn't take the burner being cranked up to generate a decent amount of heat but if you do the ceramic can get red hot and not be negatively affected.
In a boat or an RV this can keep you quite toasty by itself and with a fan can heat larger spaces amazingly well.
>The watts you produce will disappear into the phase transition of water into water vapor. That's not warming your air or you.
Energy is neither created nor destroyed, moron. The energy consumed by boiling the water is released into the air as the water evaporates. This is why sweating cools us down: the evaporating water "carries" the heat away and into the air. Is the 4th grade coming back to you yet?
Also, the efficiency of a heat source is the ratio between the total energy consumed and the amount of thermal energy that actually makes it into the living space. For example, my gas furnace is 96% efficient because it is able to release 96% of the total chemical energy of the gas as heat into my house. The thermal mass of an object being heated on a stove doesn't affect the total amount of energy being consumed nor the amount of heat energy that is actually released into the living space. The only affect thermal mass has is it's ability to release the energy it took to heat it up as it cools back down.
>evaporating water "carries" the heat away and into the air.
Nobody tell this guy how a swamp cooler works.
If the water serves no purpose, a heavy iron griddle would probably be slightly better, but yes the pot of water will keep the heat localized, at least until the point where the water boils.
If the hot water does get used, obviously just do that. The only important part being that water is never poured down the drain until it is near room temperature.
>The only important part being that water is never poured down the drain until it is near room temperature.
Oh good God I pour boiling water down the sink all the time, am I fricking up my pipes?
I the UK there are special stoves that do that called augers I think. Everhot is a popular modern electrical one.
>isn't that more thermally efficient to heat the house than just the burner being on, by itself, with no thermal mass (boiling water) on it?
The same amount of thermal energy would be released into the living space regardless if a pot of water is present. The only difference is that when you boil water, thermal energy continues to enter the living space after the burner is shut off as the water cools down to room temperature.
Thermal mass doesn't effect the efficiency of a heat source. It only holds thermal energy and releases it later.
>same amount
No. The latent heat which goes into the phase change of making water into steam is lost.
I'd imagine you're losing a lot of potential heat through the stove hood. We just ran a gas line to the living room and installed a blue flame fireplace.
The amount of energy being generated is the same with/without kettle. The only difference is that the kettle accumulates a little bit of energy that it will release after the gas is turned off.
Ofc is very little energy being accumulated in the kettle. 20 litres of water at boiling point will only store 1.5 - 1.6 kw of heat
another one who doesn't know the difference between kW and kWh
Ofc i mean kwh you stupid Black person
you were only pretending to be moronic, right?
This guy should get your mother and heat her up.
She is so fat she can pull 1000 kw HOURS just with her fat breasts.
happy now?
do you always get this upset everytime someone points out you're moronic?
you sound like woman. Only a hole goes around pretending everyone is emotional.
you sound like a moron
you are the moron
i'm not the one making moronic mistakes like
moron is getting defensive
yes you are you dont even know what a watt is
moron is getting aggresive
>kw of energy
go back to school kid
tomorrow i go back just like every day, we dont care about covid anymore but you are a moron, you have not even seen a watt in your life moron
ah so you're underage, explains a lot
keep studying kiddo! you need it
Back in poor college days we'd all huddle in the kitchen and boil 4 giant pots of water with cedar boards and cinnamon sticks in it. Kept your body temp up enough to stud through the winter.
