Need advice on water heater?

Hi,
My heating system is water. It is an old system but I never had a real problem. Last week I started the furnace, however I had to move the thermostat up and at around 65. It started ok, but it would not turn off the furnace. It was a White Rogers with mercury. So I bought a Honywell non progamable because it only have 2 wires and I don't need anything fancy. I installed it, also I got a new expansion tank since the old one had a leaking diaphragm. Everything works. It starts and it turns off at the temp I set it at.
Now here is what I don't get, the furnace turns off but then the water in the tank cools down to a point where the pipes and radiators feel cold. This morning I also heard a lite sound like whistling almost but only when the furnace has reached the temperature and is close to turn off. I did not have these symptoms before I installed the thermostat. The radiators always had a warm feeling between stopping and starting.
Perhaps someone here has an idea, because this is nuts, sorry.
Thanks in advance,
Matt

What you need to do is have a hydronics person look at your system. You said you had your expansion tank replaced. Didn't he test your boiler after the installation?

Hi Keith,
Well I did install it myself and it is working. The pressure is good, no leackage on the relieve valve. The proplem is that the pipe coming out of the boiler tank is still warm one hour after the furnace stops, but on the entry to the boiler it feels cold also the boiler is warm to. I have the feeling that there is some air in the piping, that is what i hear, but that could be just me.
You say to test the boiler. How would I do that?

Hi Matt-
Like I said, you need to get a hydronics guy in there to go over your system thoroughly. Be there and ask questions. Educate yourself, and like any education, it's going to cost you.

Hi Keith,
You are right ,nobody works for nothing. I will have a someone coming to check it out. He lives 3 houses from me that is his specialty. I talk to my neighbor about it and he recommended him because he has the same system and this person fixed it.
Actually I have been monitoring it all day and somehow it works well now. Regardless, I will have it checked and I will let you know, but I feel better,
Thanks Keith, wish you where my neighbour. Winking smile

Your welcome Matt. As a former Montrealer, I know the importance of having ones heating appliances in good shape. The snow piles a lot higher there. Your fortunate to have a boiler guy a few doors over. Stay tight with him.

Hi Keith,
Yes it is nice to have someone close. I know his Dad very well before he past away. He will come Monday or Thursday. Right now the system works great no noises, perfect pressure, but I like to be safe.
Sorry about my english, not my first Lanquage.
Have a nice Weekend Keith, perhaps we where neighbours before, hahaha!
