Anyone have a tankless water system installed in their home? If so what brand/model do you recommend? Considering taking on this home improvement challenge over the holidays. In typical fashion this means yours truly and my best friend Darold Wiley will need to run a new 3/4 natural gas line and turn the hot water closet into a nice pantry for my sweet wife. What do you get the woman who has everything? Perhaps a Rinnai 75 LSI under the tree now that sounds so romantic...endless hot water...ha, ha!
