Is it better to have your water pump run all the time or cycle on and off with the thermostat. And do you think you would burn more wood with the pump running all the time.

my vote...always on

always hot water when needed..no waiting for cooler water to clear the lines
lets see what everyone else says

Yeah mine runs all the time too.  Didn't like the cold air when furnace kicked.

My water pump turns on when wall thermostat calls for heat. Set up via relay. When I installed outdoor boiler, I too was concerned anout cold air from water pump lag time, but reality is, convection currents always keeps warm water in the heat exchanger. My unit never blows cold air, even if thermostat hasn't called for heat in a while.

I think many are set up to run continuous when hot water heat exchanger is on the same line as the furnace heat exchanger. My heat exchangers are on seperate lines / pumps.

Either way works fine.

Another reason to run the pump all the time is that it helps mix the water in the furnace and helps keep the water in the top of the water jacket from boiling as easily on hot days.

I agree. I also have heard of problems with the pump not running all the time,and then the impeller siezing up.Probably due to hard water or junk in the water.
