Storage hot water heater (gas)
I have a large Victorian home (1890). Our house was retrofitted with a pex plumbing system, hydronic baseboard heat, and a condensing boiler. We get our domestic hot water from a coil in the boiler. Our gas bills are very low, but our domestic hot water situation leaves much to be desired. If you are running a shower, and someone turns on the hot water anywhere else in the house, the shower pressure drops way down and/or runs much cooler. It takes FOREVER for hot water to reach some of the faucets. We are very miserly with our hot water, so turn the hot water on and off on short cycles for things like dish washing. I am thinking about having a storage gas hot water heater installed to hopefully alleviate these problems. Would it make sense to run the new hot water in series with the boiler? Or should I just cap off the boiler coil? Or maybe run the boiler hot water to one fixture and do everything else off the storage? Any advice would be greatly appreciated.
