Re: Most efficient way to boil water on a boat

Oddly the higher wattage element would use a bit less power. This mainly due to the extraheat loss from the pot for the double amount of time it would take at 750 watts. But then the Peukert factor...

Re: Most efficient way to boil water on a boat

Diesel does offer more BTU's per gallon or liter then propane. Roughly 31% more. In the US, propane, in California anyway, is $3.50 a gallon and diesel is somewhere between $2.70 to $3.60 a gallon...

Re: Most efficient way to boil water on a boat

They are sort of kind of technically correct in that an immersion resistive electic heating element is in and of it's self near 100% efficient. That is a Kw input gives you almost a Kw output into...

Re: Most efficient way to boil water on a boat

Oh dear me.

One sometimes wants to heat hot water hotter. So you CAN have a hot water heater, be it a desuperheater, deaerator, a booster heater in a commercial dishwash application (taking 140...

Re: Most efficient way to boil water on a boat

Sounds about right.

Casinos also need cooling year round, (400 watts per slot machine x 3000 slots) though there is some "free" cooling available in northern areas. I think of Missouri as being...

Re: Most efficient way to boil water on a boat

Nothing like throwing a lot of BTU's to heat water instantly. The typical instant hot water heater for homes run at 160,000 to 199,000 BTUH. That's a bit over 2.2 gallons of propane per hour,...

Re: Most efficient way to boil water on a boat

For propane at $3.4 a gallon the cost would be 2 cents for two cups (1 pound). So a penny a cup is just about right.

For an electric kettle with a 1000 watt element the cost would be about 1.7...

Re: Most efficient way to boil water on a boat

I'm an engineer, it's what I do for fun. Though more likely with 700 BHP scotch marine steam boilers. But you are right, I still use propane for boiling water.

Re: Most efficient way to boil water on a boat

You are correct in theory, but much of the heat from a gas burner goes around the pot and not in the pot. So the times are a bit misleading. Burner size and shape, height of pot over flame all play...

Re: Most efficient way to boil water on a boat

There was a discussion about electric kettles a few years ago. Cotemar is of course 100% correct that a electric kettle in itself is more efficient then a gas or electric stove or microwave. That...
