Constant Flow

Melton

in THE MAIN WALL
I am working on a major retro fit on an old farm house. I am trying to get some ideas.

I have read a number of articles on constant flow circuits, mixing valves and injection pumps. Is constant flow the way to go? In a multi zone system, does it make sense to run circ pumps and mixing valves on every zone? Does the cost of running all the pumps start to eat away at the fuel savings? In terms of a rough price estimate, what does it cost for the cirs and mixing for each circuit?

Any help appreciated.

    Plenty of right ways

    to pipe and control hydronics. If all the zones require temperatures within 12-15 degrees of one another, really no need to have a mixing device on every zone.

    Outdoor reset properly installed and set up, will give you near constant circulation. Coupled with injection mixing on reset you will have boiler and system reset.

    Some of the modulating boilers on the market have this reset built into the unit. As well as DHW priority. Could be about as ideal as it gets.. modulating burner, reset on the boiler, and system reset. That's a tough combo to beat for comfort and efficiency.

    It all comes down to picking the right pieces, matching the heatloss, and finding someone to install it all properly.

    Only then will you experience true hydronic bliss :)

    Oh yeah, make sure you tighten the structure, insulation, windows, and doors to the best of your budget. No sense in letting the fuel dollars escape too easily. The structure drives the fuel bill.
