Gas hot water heater question

Last night, my wife found our leak detector going off in our downstairs utility room. She said there was haze in the room by the hot water heater and a strong odor. I came home quickly and found the smell to be . I shut the gas off at the tank and aired the place out. The folks came out and pressure tested everything to the furnace and hot water tank and said everything was fine and is probably the furnace or hot water heater. I strongly lean to the hot water heater because it's been making noises during the day and when it heats up water under peak demand, it's very loud. Just my $0.02.

Any ideas as to what could cause the leak if it is the hot water heater? Really, I'm not sure I trust it anymore and am STRONGLY considering going to an electrical.

Thoughts?

Did the test the connections with air? Bubbles? Did they test the gas valves?

What "leak" detector was going off? Gas? Smoke? CO? Water?

What "Folks"?

For some reason, when I posted this and my previous message, the word pro-pane (misspelled on purpose) is getting removed. WEIRD!

The propan_e folks came out and pressurized the system and it held fine. They also sniffed around the general area of the water heater and found nothing. They didn't test the gas valves. The propan_e detector was going off.

The plumber that installed it said that what's probably happening is that the propan_e tank was not filled up enough and was drawing air. The tank meter shows 45%... he said that it would happen around 20-30% and the meter has enough variance in it that it could be in the 30% range.

Thoughts?

tank

The tank is a pressurized sealed unit and does not "draw air", and if it did it would create an extemely explosive mix in the tank AND in the piping. DO NOT turn anything on until you have determined the source of the leak. It could be one of the connections or a defective control. BUT since propane is heavier than air ANY leak will put gas at the floor level and eventually it will fill up to the point where it will ignite and leave you without a house.

you said a haze and an odor? you also talked about a detector? What kind of Detector? If a water detector , steam causes a haze, hot water on certain materials can cause odors. Could the pressure relief valve have blown? You have already have been given ideas if it was a gas detector

The filters which bbs operators must use to help limit spam, and other content which they do not want, are sometimes "undereducated" and block words which should not be a problem. One example is the simple word for an expert in a field...spelled S P E C I A L I S T. If I simply type specialist, you see the result.

Now I will type propane and see what happens.


EDIT: Well, propane does not seem to be a problem, and I did not think it would be. Looks like they fixed specialist. The reason that one used to pop is that embedded within the word is the name for a certain medication which for a while was beings spam-promoted so heavily, you couldn't get away from it. ( Drop the first three letters and you will see what I am talking about.)

Anyway, thanks for your post. We will try to get to an answer. To summarize.... it was a propane detector that went off, the smell was propane, and the haze was escaping propane/air? This sounds pretty dangerous. Have you gotten a good fix on this yet?
