Now that the weather has warmed up I'm having trouble keeping the OWB lit.
What's the recommended setting for DHW  during the warmer months.
Thanks,
Brian

can you let everyone know what make and model boiler you have.

I think he has a Heatmaster, if so I'm sure Yoder or Scott will help him out, he might try tightening up his differential a bit or try batch burning, just a thought.

Heatmaster  4000E

You can turn ur temp down but probably no less than 155, delta T of using just the 20 plate shouldn't be over 15.  With that being said you are more likely to develop creosote n such running cooler especially if your wood isn't top notch.   I've been experimenting with mine a little in this regard. 

It sure doesn't take much wood for your domestic use

TOTAL GUESS on this one, but why not try and light the OWB once a day to fill hot water heater (with say 140f water); guess is one larger burn cycle will help burn more efficently than a bunch of little ones all day.  Plus what is capacity of your OWB? In my case 250 gallons, so after the fire goes out you should still have 250 gallons of water above the temperature of the Water Heater, so it will still transfer heat, until the temperature equalize

SIDE NOTE/BONUS: Whoever wakes up last (typically kiddos/wife in my house) would get a luke warm shower

The 4,000's are for sale?  I thought those were still top secret!!!

There not for sale in many areas, only in va, nc, and parts of wv

That's not a regular HM model at this time

Its not called a 4000 any more. The new line is the C125, C250 and C375. I run mine at 150 with a 5 degree differential when the weather is warmer. But there are a number on here that would disagree with that.

  Yoder, being that I promote our units running hot, I would like to go on record as saying to do as your dealer or manufacturer asks with temps, my boiler likes it hot and does not do well at low temps, there are way to many variables with solid fuels for any perfect solution, if I gave inaccurate diagnosis, I do apoligize, if I send you my info again can we talk.

 Burning hot eliminates creosote and build up in the furnace but on these stainless furnaces I don't see any other real problems with running at low temps. But each person has different opinions on that. Doesn't really matter to me, it works for me but I'm not going to say everyone should do it. lauren@yoderheating.com

MF4000E put in operation last fall. Backed off the temp to 162 with a 15 degree differential. Seems to be doing ok now. Thanks for all the input.
