What percent of my oil is going to my DHW?

[TKT]

I am planning on junking my slant fin cold start boiler for a kedel wood pellet boiler. I am try to figure out if a heat pump DHW tank is worth the extra money or if i should go with an Indirect tank off the wood pellet boiler. Knowing how much oil I was using for DHW would help me decide

Depends on how much you use...

Average I would say .5 - 1 gallon a day for ""MOST"" people. So 60-120$ of fuel.

I tracked mine for just DHW. I have a 41 gallon indirect Boilermate setup. I was burning .5 gallon/day just to make hot water for 2 showers and 1 dishwasher every 3rd day. Once I learned that, I plumbed in an electric heater the next weekend.

The best of both worlds is an electric with a sidearm so it's an indirect in the heating season, and strictly an electric water heater in the summer. If your heating season is really short, then a heat pump would be cheaper to operate, but more $$$$ up front. I'm installing this setup electric/sidearm replacing a Bock oil water heaterthis week, I can take some pictures. An alternitive to the sidearm, is if there is a domestic coil option in the boiler, plumb that into the electric tank with bronze circulator. Basically an indirect with an external heat exchanger.
