Hot or Cold make up water? in steam boiler system

I have a manual water feed to my steam boiler. It enters into the wet return.

It is a cold water feed, would it be better if it were hot water?

Unless you live near "Old Faithful" or some other source of free geothermally heated water, then the answer is no. And if that were the case, just pipe it thru your radiators.

Yes, cold water has to be heated to boiling to produce steam, and hot water would be require less BTU's to get it to steam. BUT, if your hot water must come from your hot water heater, this is not nearly as efficient as your boiler. Plus, once the "hot" make-up water mixes with the water in the wet return, it is kind of "overwhelmed" by the volume/temperature of the return water.

Like they say If it works let it alone. But Id look into a low water cut off and mechanical feeder for your boiler there.

If your system needs more than a gallon of water every couple of weeks, you had better find the reason. That water never goes away, it just condenses and returns to the boiler. That is what prevents corrosion. Stale water.
