Stratification

[huffdawg]

After re-plumbing the piping between Buffer and Storage tanks utilizing opposed circs I seem to be getting stratification now . Overnight the storage tank tops are still running temps of 174 or so instead of being 145 from top to bottom.. No more dhw shortages in the mornings.

Good to see. How low of a temp can you go for the? Is your webpage temps correct now.

 

[huffdawg]

Yes the webpage is real time

for the what?

Sorry for the dhw

I think around 135 - 140f will give me usable shower hw.

OK thanks. My DHW coil died in my oil boiler, and I have to decide if I want to replace it, buy a heat pump, or continue using my wood boiler and storage tank to make hot water.

I think if I was faced with that, I would put in an ordinary electric hot water tank/heater (or gas if you have that), and heat it when the wood boiler is heating (assuming you're doing that now?). Can be done with a sidearm - not sure what you have now. Not sure it's worth it to heat DHW with wood in the non-heating season, as heating ours electrically is only in the $20-25/mo range at $0.18/kwh. I definitely wouldn't go back to oil & a coil - been there, not going back.

HPWH might be a choice too, if there are incentives where you are.

I have 2 nyletherm heat pumps used for 3 summers now .. nice not having to burn wood in the summer.

Yes I am considering buy one from Tom. No there are no incentives. My concern with not using oil, is corrosion in the boiler, and vent when sitting cold all summer.

With the geosprings discontinued at the end of the year there might be some deals to be had.
