Question Infloor heat -Spirovent problems

Can anyone help me please?

I have a 3 zone radiant heat system with a Spirovent microbubble air eliminator. I also had air in the automatic fill tubing which allowed the system to lose pressure, with no water going in.

Another forum told me to bleed the system. Stupidly, I used a wrench on the spirotop vent and broke it. Now, I have no heat and it gets into the 40s here at night. I could use some help right away.

After much searching on the internet, I learned that Spirotherm makes a Spirotop to be used separately or it can replace the one already on the spirovent. so I got a spirotop. The instructions with it said to use 2 strap wrenches to get the top part off.
Well, strap wrenches just slipped, so I used my pipe wrenches. The darn thing will not come loose. I was considering heating it up with my torch, but thought I might damage something inside.

Does anyone know - is the top of the Spirovent really replaceable? Is it sealed with something that I need to dissolve off or something? How do I get the top part off?
Spirotherm won't give me an answer.

Thanx mucho,

puma

Spirovent

Sorry Puma but I've never tried to take a Spirovent apart. You might try contacting the company from whom you bought the replacement part.

I have taken a spirovent apart. Twice. The heads are replaceable.

Pipe wrenches, not strap. Lots of force, slowly and evenly applied, etc. Obviously go around the thick middle, stay away from the top where the float assembly, etc. is located.

However, I don't know that the spirotop is a replacement for the top of a spirovent. I thought the spirotop is kind of like a taco hy-vent, i.e., small. I bought a whole new spirovent and just took the top part off and spun it onto my system. You can get replacement heads, but they are not often stocked. (Apparently these things almost never fail.)

Hint. If you buy a whole new one, the smaller inlet pipe sizes can be much cheaper than the larger, e.g., spirovent with 3/4" inlet about $20 less than 1".

Wink Spirovent problems

Thank you members! :>)))

The Spirotop does indeed fit the Spirovent. All you have to do is screw off the bottom and it's the same as the one off the Spvt.

I probably would have given up and ordered a whole new one. Thanks for the encouragement and advice.

Now I'm waiting for heat and pressure to see if it leaks...

Thanx again,

puma
