To hot upstairs

Some pictures of your boiler and piping. Sounds like you may have a flow check problem or possibly a lack of flow checks

  • Too Hot Upstairs

    Hi,

    Just had a new boiler installed Munchkin P80 w/indirect HWH and I've got a few questions for you guys.

    1) the heat upstairs (zone 2) is constant. Even with the thermostat turned down the heat keeps coming and coming. Any ideas?

    2) Also, it seems to be taking a lot longer for hot water to reach the second floor sink & Shower. The new system is placed about 10 feet to the right of the old one. Would this make that much of a difference?

    Thanks, for your help...again.

    Not sure what type of system you have? Are there zone valves? Or a circulator with flow checks? Is a flow check installed? or is it open or stuck open? I do agree. Let the licenced contractor(you did hire a licenced contractor right?) handle this problem.

    some thoughts...

    I'm a mere homeowner like yourself, and I second the call to bring in a professional to look over the system, if possible.

    Your second floor zone may be suffering from ghost flow, a broken zone valve, or messed-up wiring. A piping diagram and some pictures would surely help the pros here diagnose what may be wrong.

    Don't discount "natural" reasons either for a lot of heat on the 2nd floor, I remember roasting on the third floor in my student days because the house had such a severe stacking effect.

    As for your hot water issue, I'll wager that the older system perhaps had some element of gravity flow that is now disrupted. A recirculator on a timer like the Grundfos series could ensure hot water throughout the house.

    Constant Flow

    When you say the thermostats are turned down but the heat keeps coming, do you mean that the thermostats are no longer calling for heat? Are these stats wired to a pump relay and is the end switch of the relay connected to the boiler? I am just searching for other not so obvious answers.

    If the contractor abandoned the stats and wired it for constant flow and is using a higher reset curve, you could get overheating. Just a thought.
