This is a 2 part question. Thanks so much in advance. Does the boiler control all the hot water in the home? Meaning the baseboard heater AND the tap water? and why does it take so long for the hot water to come up to the shower? It takes about a good 5 minutes! Thank YOU!
Answer 1 is NO. they are 2 separate systems. The boiler gets its water from the same source, but it is in a closed system, never mixing with tap water. Second answer: the only thing that would explain that long a delay is distance from the hot water tank coupled with low pressure due to clogged pipes. The clog here is rust and scale on the insides of old galvanized steel pipe. I've removed pipe that had so much clog that light could not be seen from one end to the other. Only solution is to repipe, using copper.
