 shower water turns cold
Author: cherln328 (PA)

Our gas boiler is 45 years old. It works well to heat our house which is baseboard hot water heat. The problem is our shower. It comes out very hot for approx. 30 seconds then turns cool. We have to keep it running and after about 5 minutes it starts getting warm again, however it doesn't get hot, even though we have the faucet turned to the highest setting. This has been getting progressively worse each year. This doesn't happen to our sink that is in also in the bathroom which is on the second floor and it doesn't happen to the sink on the first floor. When it gets warm outside and there is not a demand for heat in the house, we do not have any problem getting hot water from our shower. Does anyone have any advice for us? Thank you.

I would say its the domestic coil in the boiler getting clogged. Best thing to do is add an indirect heater as another zone to your heating system.

Reset or remove the scald guard on the valve.

First, eliminate the shower faucet as the cause of the problem. If that is not it, then most likely the problem is with the tankless coil.

You can't determine the actual cause until eliminate each possible source or component in the heating system. It could be one defect or several defects in the system that is causing the problem. You just see the end results (effects). Yes it could be a dirty shower valve, but it could be several other things too after 45 years.

A licensed plumber is trained and certified to know what to do to begin the process, evaluate your system and then make you aware of the final resolve. Who knows what has been going on or how well your heating system has been working all these years and getting progressively worse.

Do it right for peace of mind and hot water for your showers.
Best Wishes
