ELECTRIC RADIANT?

There are two types of radiant that use electricity, direct cable and electrically heated water.
   Although I do recommend using electric boilers for large new construction because of the ability to change fuel later if electrical rates increase.

WHEN TO USE ELECTRICAL MATS.

   There are times that electric mat systems do make sense and are feasible. 
 
    If you have a small area that you need radiant.

I do recommend the electrical mats for small areas such as kitchens and bathrooms especially if you want to remove hydronic baseboards or radiators. 

Electric water heaters simply do not have enough Btu output for space heating.
Remember when you take a shower you are using stored hot water not the water that it is being heated.

We just bought a house with radiant heating in the ceilings and in the floors as well. The ceilings were all cracked. the contractor said don't worry about it.
The floors in the bathrooms are burning hot some places and ice cold in other places. I just moved up north from Florida. I have no clue about any of this. Should I be panicking?
Do you know anyone who provides service in Baltimore, Maryland?
Thank you in advance for any help/guidance you can give.
