    Default New unvented cylinder - nowhere for Evohome Probe :(

    Hi all,

    My parents have been using Evohome for over a year now, with great success. But now they are having their hot water system converted from gravity feed to mains pressure. The unvented cylinder is a Warmflow IN250UV (250L unvented indirect), here is a schematic of the tank:


    I have both the strap on sensor and the insertion sensor, but there are no available wells. Where could we attach the temp sensor?

    The plumber doing the install has never used Evohome, but he seems to think that as the secondary return isn't being used, instead of blanking it off he can get a 22mm "probe pocket" that would allow the probe to be inserted there, something like this:


    Does that sound feasible? More to the point, would it be safe?

    Thanks in advance!
