wondering if should it be making rattling noises after one year and get so hot it cannot be touched?



also could a problem with it be the reason we cant take hot showers without all pipes going back to the boiler banging because of what seems like sporadic/bounding water pressure(this has been happening since installation)?



Edit:  I read a couple posts by Noel regarding superstore hot water heaters and i think i should post a little more info.  First off, this has been happening since day one of the installation of a new psb4d dunkirk 112,500 btu boiler and superstore water heater(i believe the superstore is a 40 gallon)  This new system replaced an arcoliner which worked with no problems.  the hot water tank is feeding a washer, sink, and dishwasher on the first floor, and a sink, and shower/tub on the second.  there is minimal hot water pressure in the downstairs sink, the upstairs sink is fine, as is the tub-since we cranked up the temp, but the shower is unusable and has been since day one.  the shower is in an old cast iron tub with  a faucet which is a tub/hand held shower combo.  it fills at 12 gallons per minute and is a 120 gallon tub.  I was assured that this system would be sufficient for the bathroom, but after reading Noels posts i am questioning that and wondering if its still a piping issue and now also an inadequately sized system. (ill put the heating problems in another post unless they are relevant here too)



Any help would be greatly appreciated.
