Master bath shower has luke warm water

I just had an old hot water heater replaced. It was heated by a zone off the the oil burner. I had a new water softener and propane fired water heater installed. The hot water from all the sinks and the shower in the kids bathroom is nice and hot (a lot hotter than the old system). But the master bath shower is still only luke warm (not even as warm as it was before the new HW heater). The shower has 2 shower heads(one is fixed and the other is a shower massage type). It also has 3 jets on the opposite wall. I'm thinking that this shower has an anti-scalding feature. Any input would be appreciated.

If it has a single mixing valve, there should be an adjustment behind the handle. Remove the handle.

Do you know the brand of shower valve? Moen, Delta, American Standard, Kohler? Single handle, multi handle. Pull and lift, turn/rotate or better yet, add a picture of your shower. http://www.doityourself.com/forum/el...your-post.html Pictures need to be resized for web quality and uploaded one at a time.

It has 3 valves. One controls on/off, one controls which shower head or jets to use, and one controls temp.

Use the link I provide before to upload some pictures when you have a chance. Is it really two valves on one mounting plate and then a separate diverter above it on a separate mounting plate? Or three stand alone handles with 3 mounting plates?

if the lower valve has two handles on it then that would be the one that would need adjustment. You take the handle off and adjust the limit switches underneath. There should be stops that limit how far you can turn the hot water portion. Some make adjustments counter clockwise, others clock wise. Are pictures possible? I assumed you are still at work and unable to provide.

czizzi . I took the handle that controls the temp off. After looking at it, I realized that it has a spring loaded lever that you can slide with your thumb to raise the temp above the safety setting of 100 degrees. I've lived in the house for 14 years and never noticed it. Put it all back together and it works great. Thanks everyone.
