Hi Jeff,

Curious if you are using the pumps connected to copper pipe or plastic?

Have you tried any rubber isolation techniques?

> I have installed five el-SID battery direct pumps; four in a hydronic
> heating system and one in a sdhw system.  The "virtually silent""extremely

by

> One pump was sent back to the manufacturer for testing and declared a
normal

should

is
> how the manufacturer tests pumps.
>
> I concluded that with room temperature glycol the pump is relatively
quiet,
> with pure water ticking noises are audible, with an increase in
temperature
> the ticking increases and becomes a rattling, when then attached to wood
> framing the noise is broadcast through the entire structure.
>
> These conclusions do not seem to agree with other available info.

> Any comments concerning similar experiences or suggestions appreciated.
