    If it's a Taco, you install it with the motor's can mounted horizontally.

    What brand and model is your pump?

I wasn't aware that you would put a citculating pump on a tankless water heater, but as long as the arrow goes in the direction of the water flow that is how it needs to be,, putting a circulator on a tankless kind of goes against what it is for, the tankless will never shut off and once it is on how will it ever satisfy itself to shut down?

Does anybody have a diagram for the flow of a back boiler pump


Did you install the pump so it flows in the correct direction? Check the arrows on the unit.

How to fix a striped door hinge screw


Hinge is loose on door so you go to tighten the screw and oops it won't tighten. Not a good idea to put a fatter screw in its place cause the screw head won't sit right and will cause other problems putting the same size screw but longer might work but not always possible. Here is the fix.
  1. Support door as to not to stress other hinge.
  2. Remove screws from hinge plate
  3. Apply wood glue to holes, Insert wood splinters, tooth picks, wooden match sticks into screw holes until tight.
  4. Allow wood glue to dry, trim flush.
  5. Re-install wood screws, until snug, don't over tighten.
Now good as new. I hope this trick of the trade saves you money and time.

How do i get even heat thru out the house with a daka wood stove


http://www.hearth.com/talk/categories/main-hearth-forums.4/
You burn wood, and smoke goes up flueway.
You're not running chimney smoke through ductwork so you have a heat exchanger.
What kind of heat exchanger?
probably air since you're running through ductwork?
How much hot air or hot water is coming off heat exchanger?
How big of a space can be heated with that amount of heat?
Is the exchanger located in optimal location?

Considerations.
One room log cabin with fireplace will not stay very warm.
One room house with big wood burning stove in center, with hot flue pipe running across the room and exiting on far wall, will get warm-hot, but will cool off fast.
Why?
Because the BTU output of firewood is much less than electric, coal, oil, or gas.
Otherwise they would have made wood-burning steam locomotives. But the locomotive boiler cannot get hot enough with wood ... the boiler needs coal to produce enough BTUs to boil water fast enough to rotate the turbine and turn the wheels.

Maybe your wood stove output should be measured.
Don't forget a huge percentage of fire heat goes straight up flueway.

I would say that the wood fire/stove must have a heck of a draw to affect the bathroom heater. Maybe a separate air supply from outside via a pipe,to the stove meshed off against vermin would decrease the problem. Plus it could stop cold air being sucked across the room from an outside door.
Downdraft through the heater could happen with either vertical or horizontal vent. More important is the direction of the prevailing wind [horizontal] ingress of water/snow etc [vertical]
We often use the separate air supply in the UK and if the pipe bore is large enough 4" plus it seems to work ok.

Just fitted solid fuel stove with back boiler, water in system but not circulating through hot wwater cylinder.


is the circulating pump going in the right direction? if not reverse the pump if it is make sure your valve is not clogged going thru the pump, if it isn't a ball valve put one in, a gate valve could break off inside and it will still feel like it is working but it wouldn't be,

3 speed Recirculation pump lost middle speed


It sounds like you might have had a power surge and burnt the windings on the medium speed. If it is bothersome, you will need to replace either the motor or the whole pump. (not sure if replacing just the motor is an option.)
