On the heater zone's are heads I have two zones my question is how can you tell if the zone head is no longer works auto

But will get heat open is this how one would know or is it the thermostat how do one know
Asked by: carl
1. No heat in that zone. 2. The boiler may start to fire up and then shut down. The area of the pipe ahead of the zone valve will be too hot to touch if the valve is opening up. Be careful!

how does it go on

Asked by: handy
This is a replacement head. You must have an existing valve already installed. Twist the old head about quarter turn and lift up to remove. Reverse steps to install new head. CAUTION: do not remove head while it's hot. Disconnect power to the head and wait at least two minutes before removing.

Is this a replacement for the 561-5 ?

Is this a replacement for the 561-5 ?
Asked by: Steve
No it is not. This is the replacement heat motor for a 571 valve which is a simple open close valve for a hydronic heating system. The 561 is a three way valve. Because the replacement motor for your valve and for geothermal valves are so much more expensive than the one for a simple zone valve I have got this question before. The power heads for these other valves are different in more ways than there color.

Could this be used to replace 5101-g2

Asked by: Mary
No it can not. I was always curious about this too because they look so similar but are different in price. So I called a Taco engineer to ask about this a few years ago. The 5101-g2 and the other versions for geothermal applications have different ratings. Those systems have higher working pressure, temperature and flow rate. The valves and heat motors are different to meet this need. The power heads for hyrdonic systems work at a much lower pressure temperature and flow rate. They are not interchangeable.

What does the operating lever control ?

Asked by: greg
The operating lever allows you to manually open the valve. This valve utilizes a heat motor which can take a good 5 minutes to open and close. This lever allows you to quickly open the valve so that you can purge the zone.

Rated 4 out of 5 by from Taco Power Head, Zone valve regulator the Taco head is a basic standard of the industry valve to regulate heat in a building by zones. It is easy to replace and reliable. In my case this was a straight up remove and replace, straight up same make and model. It was not especially cheap and seemed a bit on the expensive side and Home Depot is very convenient, saved me a trip across town to an actual plumbing/heating supply house.
