EKO 40 Return Temp

[AlbertGravlin]

I just installed an EKO 40. What is the proper return temperature for it?

Welcome to the Boiler Room AlbertGravlin.
Your return temp depends on many different factors. Do you have storage, how far is the EKO from the house ? You'll have to give us more details.

Mine once it is up to temp is around 180-185

 

[AlbertGravlin]

Its 45 feet from my EKO to my Oil boiler. There is no storage.

Do you have a bypass set up at the EKO to protect against cold water shock? What is your return temp ?

 

[AlbertGravlin]

The plumber that helped me put it together told me to run a 3/4 inch bypass and the return temp is about 135.F

 

[trehugr]

How long has your boiler been running?

 

[AlbertGravlin]

First light was yesterday

 

[trehugr]

OK, What's the supply temp ? How are you tied into your existing system ?

 

[trehugr]

Where and how is your return temp gauge set up ? It could be there is a air bubble at the temp probe. We need to know more about the system before we can help.

 

[AlbertGravlin]

sorry for the delay. I tied into the existing boiler by putting the supply from the eco into the return on the oil then the supply from the oil into the return to the eco. the supply temp is up to 195 on the control panel. The return has a strap on thermometer.

It may very well be your gauge is inaccurate. Have you insulated the sensor ?

 

[trehugr]

Are you getting the heat you need to all your zones ? What does the temp gauge on your oil boiler read ?

 

[AlbertGravlin]

no the plumber told me that it would be as accurate as any other. I question the bypass is as good as a three way mixing valve?

 

[AlbertGravlin]

I am tring to bleed all of the air out of the oil boiler system. It has two zones one is up to temp the other is not yet.
