Advantages/Disadvantages of Indirect Hot Water Heating

Tags: HVAC

I am remodeling a house that currently uses a hot water boiler heating system to also heat a hotwater tank for general use. In winter, this seems very efficient since the boiler is running often. In other seasons (7 months/year) it seems very inefficient since the entire boiler needs to fire up whenever we wash a few dishes.

Over the course of the year, would I save significantly on efficiency if I replaced the indirect tank with a traditional gas water heater?

Thanks in advance,
Mike

Thanks for the thoughtful response. I am trying to understand the conclusion of what you wrote. Are you saying that even during summer months indirect water heaters are more efficient than standard water heaters?

Yes, I do have a well-insulated, 40 gallon indirect water heater, but it seems to want to heat up after just a few gallons of hot water are used. Does that make sense to you?

Thanks again,
Mike

You were just getting close to my question. Is there any way to lower the hot water temperature (to prevent scalds) out of an oil boiler and still heat the house adequately?

Is it true that you have to turn off the hot water valve when using an indirect water heater? Not sure if I should purchase an indirect hot water heater or not, need to know the cons of the indirects before purchasing any insight?
