Hot Water Smells?

We had a new oil boiler installed about a week ago. Ever since, when we turn on the hot water in any faucet in the house, there is an oily, dirty smell that comes out. After a minute, the smell fades, but its there every time. Is this normal following the install of a new heating system, or is there something wrong?

Re: Hot Water Smells?

There are three or four different ways that new boilers deliver hot water to the faucets, depending on the make or style of boiler---in all cases the hot tap water from the faucets (known as the domestic supply) is ALWAYS KEPT SEPARATE from the boiler water used to heat the radiators, baseboard, or tubing in heating the house---the water used to heat the radiators quickly becomes fouled by the residue it picks up from the radiators, etc.

Do you have well water for your water supply??? and have you had any problems before the new install with odors from the well water???

You should never get a foul smell, even momentarily from the faucet hot water supply---it must be clean enough to drink---don't allow anyone to drink any of the hot tap water until this situation is repaired.

By all means, call the installer immediately & notify them of the problem; they will have to come over right away to fix this free of charge---under the law they are responsible to install the boiler correctly & to provide corrective service for at least the first 30-60 days.

Was this by chance a self-installed situation, or something done by an unlicensed installer?

There is always the possibility they connected the wrong pipe to the piping that supplies the faucets & showers.

What type of boiler did they install???---(model & make, mfgr)---this info is on the boiler itself, there should also be an installation/homeowner's manual that comes with the new boiler that has diagrams of the different parts of the unit.

Some of the newer boilers are "combi" units that have a little tank inside the boiler for the domestic hot water supply; others have a coiled tube inside the boiler to heat the hot water; in still others there is a separate tank beside the boiler (called an indirect hot water heater, or a "sidearm tank").

In other cases, there is a separate hot water heater for the domestic hw supply that is not connected to the boiler in any way.
