NE WOOD BURNER

Has any one had any experience with a hot water tube/coil hooked to a new wood stove? I assume if they exist now they would have to be mounted external.
It seems to me with the long burn times of most new stoves it would be ideal for steady DHW heating.
 
I asked Woodstock about this a while ago, and they didn't like the idea at all. Don't remember why now, but the discussion made sense at the time....

edit: Was asking about an internal coil....
 
There is a system that some Pellet stove users have.

Its called the "Crosslink" system, IIRC?

It makes it a small boiler, or kinda...
 
i just built a new house and considered this. Even during new construction I didn't think it was worth the pain in the a$$/cost/risk(water damage from failure). I have read some threads on the subject, mostly positive, "free hot water". The Energy Guide sticker on my cheep Whirlpool says, $508 per year average operating cost @ 10.7 cents/Kw. I get Kw's for ~ 1/2 that, probably use 1/2 the hot water of most homes, so it wasn't worth in for me. I'm all about free. Keep researching, you may decide it's right for you.

Put an intertherm timer in line from the fuse box to my hot water heater, got two sets of pips, and have it set to run off peak, both early morning and evening. Total of about seven hours, gives me all the hot water I need for the days, saves a LOT of money. I'm heating cold, deep well water, which doesn't help....
 
I like the idea, but after weighing the cost, payback, risk(I hate water leaks/damage), I didn't think it was for me. Most users are happy, I just did't think the ~$75 a year I would save was worth it.
 
My neighbor has a hot water boiler running off of his stove....he loves it

Firm believer, and I save A LOT more than $75 year.

Putting one in my next stove too,

Worrying about water leaks seems kind of silly to me, but I am a plumber.
 
Thanks for feed back.
I know the internal coils work well. I was just curiuos if anyone has tried an external coil.
 
External is problematic due to poor heat conduction of air. We can discus it further if you like

Interesting Dune! Do you know if this coil would create problems with a secondary burn stove? My current DHW setup is via tankless coil in a oil FHW furnace.. The furnace is expensive to run for hot water this way as the oil burner cycles every 1/2 hour or so to maintain the water jacket temperature..

My stove is a gasifier. I am sure I use additional wood and air due to heat loss to the coil.

A gasifier is a wood furnace, correct?

What a great electric rate. National Grid in Massachusetts is @$.135 total.when Cape Wind turban farm kicks in we'll all pay a little more. They are guaranteed $ .187/kw ,add to that transmission costs up to around $.25/kw.
 
National Squid rates in Mass. are ridiculously high! My town abuts Middleboro which has municipal power and so does Taunton and they have MUCH lower rates..

Don't even get me going about Ontario Hydro..

First: They multiply our usage by 1.092 to compensate for the power they lose in transmission, so we pay for almost 10% more power than they actually deliver. And we pay a 13 % Harmonized sales tax on the almost 10% electricty we never get. Our nominal on peak rate (in winter from 7 AM to 11Am and 5PM to 7PM-pretty hard not to use power then to bathe and feed people-) is11.8 cents per kw; mid peak 9.9 and off peak6.3 cents. Then they add delivery, regulatory charges, debt retirement charges, harmonized sales tax of 13%. Included in one of those charges is the cost of the 80 cents per kw the idiot company is paying for purchase of solar energy (which has resulted in German Cos coming in and building multiple solar farms on woodlots, which they are clear cutting, setting up lots of little cos to avoid the limit on KWs that can be sold by any one business to Hydroone....you get the idea).

Although over 75 % of my power usage is off-peak, and I havedone evrything I can to minimize power usage, my three month usage of 2544 KW (which includes some in Nov/Dec when I was away from home for electric baseboard heat) cost $622: 25 cents per KW hour. Back breaking. Wood heat pays for itself soooo quickly and is much more comfortable.

I would love to install one of these water tubes in my Napoleon 1900P in the kitchen, it'd be the perfect setup for my water heater and I'm sure it would help curtail some of the gas bill (what's left of it!). But I am pretty sure if you install one of these, you nullify the UL listing of your stove, making it an illegal install in the eyes of your homeowner's insurance co. Am I correct about that? That's the ONLY holdup I have in regards to installing one in that stove...

WOW? I can't believe $.25/kw and I'm bitchin at $.133/kw down here. US looks like a bargain vs Canada on electric. Is there a big push up there for wind as well? by the way back in 2000cost/kw was $.08

Yes, and when I built in 76 it was 2 cents (really 2 cents, none of the add ons), and they were pushing electric heat because it was clean and cheap.

Yes to the wind energy. Not like the solar though.

electric same here in the early 70's now down here they are doing the prop on wind and subsidizing with tax dollars and consumer rates.obviously the market can't find it's own way.i cut my uasage every year and bill is always up, i'll live in the dark soon

When I take our total e bill with taxes and all it's about 15cents a kilowatt hour.

Total e house and we pay usually around 130-180.
Thank God for wood or it would be way higher!
