Noisy Smart 50

Slimpickins Member Posts: 340
I commissioned a Prestige Solo 110 with a Smart 50 indirect today and the indirect is making a lot of noise. It started as it was being heated from a cold tank and I just thought it was expansion. Ater the tank reached temp,  I ran a faucet to adjust the mixing valve it was still making noise, even while just sitting there doing nothing.It's kinda of a metalic noise that resonates.  It has a potable expansion tank so I'm not sure whats going on. Anyone else experience this?

    check tank venting

    any chance air is trapped at top of tank on the boiler side?

    No air

    There is an autovent on top of the tank so air shouldn't be a problem. I talked to my supplier about it and he said the tank is packed pretty tightly with foam and that may be it. The noise isn't as bad as the first day of operation and the customer said they could deal with it.

    is the pressure on the domestic side? I've had this happen a handful of times, and the solution was a PRV, and x-tank. In those cases the line pressure was over 80..too much.
