I have an oil burner furnace that includes built in on demand hot water. When we moved in back in July the hot water in the house was fantastic! You could take a 20 minute shower and not lose hot water at all. Since we started using heat in October, the hot water in the house sucks to say the least. If I get 2 minutes of hot water, that's a lot. But sometimes the hot water is great. I think I narrowed it down to when the heat is on (and the furnance is running due to the heating demand for hot water), the domestic hot water is also great. If the furnace is NOT on when the domestic hot water demand kicks in the furnace doesn't seem to be turning on to heat the water. So, the only hot water you get is what is in the coil at the time.
We had someone in to look at the furnace because the heating wasn't working properly. Turns out the heating zones were all air locked. They bled the system and solved that problem. But the domestic hot water continues to be a problem. Is it possible that there is a problem with the thermostat (or whatever it is that triggers the furnace to turn on when the domestic hot water is calling for demand)?
Any ideas and suggestions would be great.
I did see the other post that recommended the ERGOMAX heat exchanger system. I understand the principle of that and it looks like a good alternative. I would just like to figure out exactly what is wrong with my current system so I can make an informed decision with how to proceed.
