It Depends!

A primary loop in a commercial installation usually runs 24/7 all season- only off when the whole system is shut down

Residential can be either but I prefer on demand to keep the parasitic loss as low as possible

So couldn't I just land the pump on the same terms in the aquastat as the boiler motor?

I would wire the primary loop to circulate anytime a zone pump has to run - and rest anytime other
this includes [very important] the dump zone

BUT [ it depends ] on if the primary loop is too long or too large or 6 other things I missed - if that will be the correct action for you

What are you using for an aquastat on the Van Wert? If it is a triple aquastat, you can power the primary circualator off C1/C2 and connect the TT terminals to the isolated end switch in your Taco zone control.

Another option is to run the primary circulator off its own relay and connect to the end switch in the Taco control.

There are pros and cons to each setup.

hydrostat 3250, I may land on the C1/C2 like you suggested.

I would do that way if you have the Hydrostat. Make sure the pre-purge feature is on.

hi limits vs Target limits based on a programed and unchangeable factory set ramp [ based on]
Thermal image temperature sampling

Call me OLD fashioned - but this thing isn't my first choice for solid fuel
works nice on oil and NG

Its only saving grace in my world is its ability and built in ODR - if you hook it up

For the price and what options it allows me to have vs a standard honeywell trip astat, its an affordable upgrade for a poor man.

If you filled the transmission to full on a van wert it will do that as it pleads out the top bleader hole on the lid, keep a good eye on it but as long as its not loosing all the gear oil it will be ok.

I new a fellow that had one leaking beyond controll, he stuck straight grease in there and it lasted for years

Seals and gaskets, but choose the time to repair it if that becomes necessary. It is not like the shafts spin at 10,000 rpm, so keep an eye on it, and that goes for all folks burning in stokers. PPPPPPP.
Preventative Maintenance is MUCH cheaper, and MUCH less stressful on the body. Hope it is resolved easily, and you will learn quite a bit about your stoker assembly, too. :idea:

Just a really late follow-up post on my first year with a kick ass stoker boiler. Other than a super light oil drip this thing has kept up and outperformed all my expectations. A huge thank you to Scott and all he has done, I still have to send up the gearbox but ill get thier soon. Another big thank you to all the suggestions and recommendations everyone has given.

Good to hear your doing well with the Van Wert.

Are you still running it for DHW?

A note on stoker gearboxes:
Most of the gearboxes I have had leak. Usualy this is a small leak, a drip or two a day. If the leak is bad enough that you have to fill it once a week or month, you might want to do something about it. You have to decide at what point you pull the gearbox and fix it. The leak won't hurt the gearbox as long as you don't let the oil level get to low.

A little pan of speedydri works well. IMO they all leak a little as the seals age and dry out. Not a mechanical or operational issue, but if you are the type who wants an 'Operation Room Sterility', when the demand is off, take it out and replace the seals.
