Cindy,

Part of my problem was perception.

My old 1949 oil-fired boiler got very hot and could raise the temperature in house by 8 degrees in about 1 hour.

This summer when crude oil hit...

When I change my Mueller parts out, the regulator was not regulating, it was letting water enter above 25 PSI and my safety valve was triggering at 35 PSI, not 30 PSI.

I don't think it is unusual...

Lottawater,

The 1450F is the correct part and includes both the pressure regulator and relief valve. It has 1/2" female threads on both ends

A one-way valve is as known as a backflow preventer.

Lottawater,

It is a relatively simple job, but I would ONLY start it if you have some experience with soldering copper pipe (or have a friend who does). Remember to clean, flux and heat well when...

Lottawater,

I suggest you post some pictures of your setup on photobucket and then we can give you details on installing the new Watts parts. It is hard to describe such a procedure in detail,...

Normally, when you bleed the oil line you should have cleared the air within 10 to 15 seconds and should tighten the nipple as soon as you see oil.

Steele66,

It sounds like you have a zoned heating system.
You can have separate thermostats for different rooms in the house. Only the room(s) thermostat that calls for heat, gets it.

1) Check if the furnace is warm too, over a 6-8 hr period.
If the furnace is cold for 6 to 8 hours, it would be very unlikely that any radiators in the house could be warm.

2) Are you sure this...

With electric boilers, the replacement of the air vent should be very easy, if the boiler was installed properly.

Electric boilers normally should have a service (maintenance) valve at the inlet...

It sounds like you have an expansion tank and/or water regulator problem.

For newer type expansion tanks, before refilling your system, you should check the pressure with a tire pressure gauge. It...

Is your boiler gas fired or oil fired ?

If you have an oil fired burner, I would check the burner aquastat. Possibly, it is either defective or someone recently set it too low. Normally they are...

45 PSI is way too high. Don't you have a safety relief valve that opens up at 35 PSI on your setup ? For two floors the pressure should be under 25 PSI when the boiler hits peak temperature.

Tomzy,

All the posters bring up the very important point that you cannot guess what components (like piping size, circulator pump, etc) you need in a heating system.

NJ Tropper,

You are correct. I started with one ET-60 and found the PSI was on the high side (high 20's) when the boiler hit peak temperature (180 F). I installed a second ET-60 and the PSI ...

I am assuming the following:

1) The supply valve is turned off
2) The ET-60 has been repressurized to 12 PSI.
3) The boiler is partially drained and so the water gauge is correctly reading at 0...

La_koala,

The weak link in ET-60 is the rubber membrane.
I don't know the typical life span of the ET-60.
My original old-fashioned expansion tank (no rubber membrane) lasted nearly 50 years.

It is likely one of two things.
Lack of air pressure in exp tank or ruptured expansion tank membrane.

You need to measure the air pressure of the exp tank with no static pressure in the system....
