I have an oil-fired boiler with an internal coil for domestic hot water.
The quantity of hot water is barely adequate at one shower, but runs out too
soon at the other shower. Hot baths are impossible at either location.
Family members are insisting on an upgrade. What are my options?
I have no gas/propane on site, and electricity rates here are way too high
for an electric water heater. In fact, I'd like to avoid a separate hot
water heater altogether, if possible. I've heard of a "booster tank" which
appears to be just a holding tank with a circulator. Is this a worthwhile
All advice/recommendations will be much appreciated.
