    We have an old peerless G561ws boiler in our house, which is heating the house fine. It has some sort of built-in domestic hot water capability but the temp is not staying consistent. We've gotten a lot of suggestions. Change the coil, replace the sidearm, nobody knows for sure. We already had the mixing valve replaced and that had no effect.

    We're wondering if there is a small relatively inexpensive tankless out there that could take the existing hot water and bring it up to temp. We might be able to do electric, although our box is near capacity, so gas might be better. We did just replace our electric stovetop with gas, so that circuit might be sufficient. It seems like electrics are less expensive to install.

    Just wondering if something like this would work. Any other thoughts??
    Thanks in advance!

    If you've never cleaned the mineral deposits from the coil, you could start there.

    Yeah, our furnace guy didn't seem to think that would help much. Is there a product/method you recommend for that?

    He wants to put in a new coil, and we are looking at possibly less expensive options. And also not certain that will help.....

    A lot more confusing thoughts on the subject here:
