Just bought a home. The water furnace was inspected as part of a set of the whole house inspection and deem good, next to one problem: some pipes connected to the water kiln needed to be metal instead of PVC. This was fixed by the previous owner at my request.
I move within. I can get hot river at any tap contained by the house, but (especially in the shower) the hose will only be hot for a minute, then it will grow bit by bit cooler and cooler. This is with lone the hot water faucet on, at full. The (gas) river heater's pilot light is lit, and it is heat up water as a rule, and the temperature is turned up typically.
Is it possible that the cold-in and hot-out connections have be reversed, possibly when the pipe work was done? That is the simply logical explanation I can think of, since the coldest dampen would be lower in the reservoir and hotter water at the top. Does this nouns like the problem, and, if so, how do I find out for sure and fix it?
Answers: Yes, working on marine heaters, I have see where somebody accidentally plumbed the hot and cold hose pipes together and it gives this same symptom.
Here is what I would do. I would run river at the sink until the temperature drops, I assume justly quickly. Then I would budge to the Water Heater and feel the pipes. It the hot pipe is still hot, hotter than at the sink, later your problem is elsewhere. If the temperature is closer to what you grasp at the sink then the problem is at the cistern. Normally at the tank the hot pipe should still be massively hot.
If it is at the tank, the river coming out is only reheat, then it could be a impossible dip tube or reversed plumbed. Yes "Hot" and "Cold" are stamped on the top near the fitting. The cold sea comes in and go to the bottom through a pipe. Sometimes that "dip tube" breaks off or is missing and next the cold comes in and quickly mixes with the hot going out cause your symptom.
On most newer tanks in this day and age the dip tube is not replaceable.
About 10 years ago they had some they recall and replaced the tubes because they were mixing too much cold. (They have holes in the tube to mix "some" but turned out to be too much) cold hose with the hot to prevent scalding.
I have one case where on earth the owner was putting surrounded by a new bathroom. Some of the newer single knob tub/shower faucets have a built within thermostat to prevent scalding. They mix cold with the hot. This fellow gone that out, not wanting that feature but the result be directly connecting the hot and cold together mixing down the hot temp (affected the whole house since the different bath be near the tank).
In one other armour they had a portable washer that hooked to a utility faucet beside a hose. They would leave the hot and cold handle turned to on. That, too, effectively connected the hot and cold together.
At least I give you a way to check if it is the reservoir or the plumbing by feeling the pipe after running it some. If it is the plumbing you might grain along it if it is exposed to find where the cold is getting mixed within.
Good Luck.
Look at the top of the water stove. Cold and hot are stamped by the inlet and outlet, If you can, follow cold pipe back to biggest water inlet for house. This will permit you know if they are installed correctly. Make sure the gas valve is turned to the "on" postion and not the "pilot" position. Pilot position will fry water but exceedingly very slowly.
Good luck
