Floor heat temperature

Our house has floor heat. It is not the main heat source and only covers part of the house. The main living area has the heat pipes attached to the floor. The basement pipes are encased in concrete. The garage is also in concrete as is the workshop. Each of those areas has a separate thermostat. Boiler is electric. The boiler temperature is very low. Around 85 to 90 degrees. Is that hot enough. A heating contractor told me that the floor pipes should not be any higher. But there is no way of regulating the temp. of the AF in each zone. Is that information above correct? Thanks

    Is the living area tubing just stapled to the bottom of the plywood without aluminum plates?
    Could you post pictures of the boiler, model number and approx footages of spaces served?

    Is the space maintaining thermostat setpoint? If so, then yes it's hot enough. If not, then it should be turned up. What is this "AF" you cannot regulate the temp of?

    Yes, if you can comfortably heat the home with low Supply temperatures like that is great

    It’s really about the surface temperature of the floor both for output and comfort

    Thanks for the responses. I am away from home for 6 to 8 weeks but will get some model numbers and pics when I return. AF is antifreeze.

    The boiler will have a control to raise the temperature if necessary. You would typically be fine with up to 120 degree water temps in a system like this, but that may be limited by your flooring

    I hope you have cheap electric rates. Every °F you raise it is going to cost $

    Are there any other fuel sources available, Oil, NG, LP?
