Steam Traps

is a self-indicator of two different devices, one that works, one that does not.

An F&T works on both condensate and temperature. The thermostatic one, obviously only on temperature. No telling how each was sized.

Expensive is a relative term but then again, so is the cost of fuel for uneven comfort. If the mains are roughly equal in length and radiation served, you have an example on the working side of what the non-working side should be...

    Steam Traps

    I have a low pressure steam system with a 400K BTU Peerless gas fired boiler. There are two steam loops - one on each side of the house.

    One loop heates almost immediately while the other takes its time.

    The only difference appears to be the faster side has a Hoffman Model 55 Float and Thermostatic Trap and a vent (round - appx 6" high - with a cap over the top end - green color) which constantly release air while the boiler is on.

    The slower loop has just a normal but large Thermostatic valve located at the same juncture (end of the steam line to start of the return).

    Both drain lines combine and return to the boiler through a large steam trap that sort of jiggles and releases air.

    What's your take on this performance. Is the difference because of the two different configurations? Is it because of the vent?

    I looked up the Hoffman and it's expensive. The installation probably would require a professional.
