I have a oil fired Burnham MPO used as backup for my Pioneer. When I bought the Pioneer it came with a hot water coil that has never been installed. With the exception of the boiler and coal stove we are total electric and my bill averages less than $75 a month so I've never felt it was worth plumbing it into the hot water tank. Would it be worth it to plumb this in to my hot water heating system? If so, would I need a separate pump to circulate it?
My home is 1.5 story 1875 sq. ft. with 60' of fin tube. Basement adds another 1275 sq.ft. and has 20' of fin tube.

Welcome, if you do a search in the upper right for HOT WATER COILS, etc.. there's been a lot of discussion on them and installation pics.
Here's one example.
Hot Water Coil Project
It could help some, depending on how far away your stove is to the hot water tank, some use the thermosyphon, no pump, but has to be close and plumbed correctly. You can use a pump and temperature control. And with the proper safety valves, etc...
You could put a timer on the electric tank so its not on all the time, and only when you need it to be on. I have one on mine and its only on a few hours a day, when needed. you can override it if you need to do laundry, dishes, etc....it works good and saved a few bucks a month on electric.

Sorry I didn't look first, but don't feel that it would be worth it to plumb it into our hot water tank. It is just 6' away from the stove and the only thing separating the two is the oil fired boiler so maybe I could put a bypass on it and backflow preventer and use it to feed the boiler on days when the outdoor temps are in the single digits. I'll check the other posts.

Depends on your hot water usage.Options wrote:Would it be worth it to plumb this in to my hot water heating system?
How many people live in the dwelling?
No, thermo siphon systems work great when plumbed properly.Options wrote:If so, would I need a separate pump to circulate it?
It's pretty easy if you are handy with a torch and soldering copper pipe.
Just the two of us now that our daughter is in college, but what I was referring to was to tie it into our fin tube hot water heating system, not the domestic hot water tank.

Oh! I see, so the coil could help heat the house instead of DHW? Unfortunately, the coil doesn't absorb enough heat to have much impact on a job like that. But it does do enough to help cut electric on the hot water tank..
Thanks.
I'll give it a try. I know just having the stove next to the boiler (and hot water tank) has cut our electric bill in winter Boiler water temperature stays at room temperature which is generally 78F and my thought was that even if it only brought the temperature of the water up another 10 degrees or so it would be worth it when the boiler runs on a very cold day.
