There is technology now available (D'Mand Circ) that actually does this automatically. Saves money. Saves energy. Saves oil. Saves natural gas. Instead of running 24 hours a day. It only runs when hot water is needed, i.e., on demand and you get hot water immediately instead of waiting for it. Cuts waste considerably.
@rnvventures Thank you for your comments. I have not looked into that particular device as we have had our oil fired system completely removed and replaced it with a solar system with natural gas backup. But other viewers who have seen this video may be interested.
water to water heat exchangers almost never transfer 100% of there heat from one and another, e.g. You could have 180 F water in the boiler, the domestic hot water may only be 120 F, this is not abnormal, it all depends on the size of the domestic hot water coil. Turning down the aqua-stat will only make this condition worse.
@Mac566 You are correct in that there are many factors involved. I was not aware of them all back when I made this video, and with the 10 minute limit YouTube had at the time, I didn't have time to go into more detail. I guess homeowners who found their hot water wasn't hot enough would have to turn it back up, alas.
@HeatingOilcom Thank you for commenting on my video. I know it's a year later, but I haven't really gotten into YouTube deep enough to find out how to reply to comments (and do some other things) until now. This has turned out to be my most watched video. I just made a new one about how water saving toilets don't always save as much water as you might think. Have a look. It's called "got 1.6 gpf?"
