I was originally going to put in a small electric tankless. But after reading about how they work, I am not sure if it will work well for my needs. I will...

    Navien NPE-240A NG Leaking

    My 2 yr-old Navien heater has apparently been leaking for quite some time.

    Marry Tankless and Tank

    I've got two 40 gal tanks in a series providing my hot water with recirculating pump and non-dedicated return line. First one in the series has failed and we've been "surviving" off the one. I'm thinking of the Navien 240 tankless to feed my tank (no sense in ditching a good tank). Since the...

    Thermar super power pack

    I bought a Thermar super power pack (9kw, model HP9024s) back in 1986 but never installed it. I'm considering installing it in a rental unit. The water heater would only serve 1 clothes washer--nothing else connected to the line. Would you recommend this, or should I just spend the $ and...
