Team heat with tankless

Leo Member Posts: 770
My experience in an apartment I rented and in the house I now own is to raise the water level in the nonheating season. It seems in the case you describe there is enough run time to make some steam and the nearest radiator tends to warm up. I recommend this to my customers also as the increase in water tends to keep the steam down.

    steam overheating

    I have a customer with a tenant house that has an oil fired steam boiler with a tankless one pipe system. This problem never occured until recently when a single mom with 3 girls moved in. They all shower right after each other at night and the boiler fires for hot water resulting in the house heating up (they can run hot water continuously for over an hour). Any suggestions to correct this would be greatly appreciated- thanks.

    making steam

    Are you ising an aquastat to shutt the buner 0ff an t 180 or so on a call for hot water , it will only hit a 180 limit unless there is a call for heat. I fixed the same problem many times. just like a hot waster boiler in the summer..

    You need an aquastat like Jeffrey said. Don’t raise the boiler water level with a steam boiler. If it happened to steam the resulting water hammer would be incredible and probably wake up all the neighbors.

    I must clarify

    When I said raise the water level I meant just short of the top of the glass, in the summer only. No hammer. This is after checking the aquastat to be at 180. I have done it and it worked on more than one occasion with no ill effects.
