How can I adjust the amount of hot water available?

Hello, this is the type of oil burner I have. When I try to fill my tub, the hot water runs out in about 2 minutes and goes very cold. How can I adjust this so I at least have enough water to fill a normal sized tub?

    That has nothing to do with the burner...

    What generates your hot water? Is it stored anywhere? Common systems include a hot water coil in the boiler, with no storage or a separate storage tank which has a heating element in it controlled by the boiler. Then there is the control for the whole thing. There may also be a mixing valve on the system.

    Need to know a lot more about what makes your water hot and where it is stored, if anywhere, and how it is controlled.

    Fill tub slow, or get a buffer tank. Or start over.

    Separate your hot water heating from your home heating so you don't have to run that steam boiler all summer. There is a nice variety of standalone water heater technologies out there.

    Hi @Rickthomas77777 , You have many options, depending on what you have and what you can consider. There may be a plumbing crossover problem as Jamie implied and/or the coil in the boiler might need to be descaled. Maybe it would be cleaner to separate the domestic water heating from the space heating as Ethical Paul suggests. I think to help we need to round up some more info about your situation.

    Yours, Larry
