Is there a Disadvantage to Underfloor Heating?

[herbolaryo]

I have seen underfloor heating ---electric and those with water pipes...

1. Is there a disadvantage to underfloor heating?
2. Since it will be placed underneath ceramic tiles or hardwood which is permanent, will future repair be a problem?
3. Since there is heat, will growth of bacteria of molds be faster?
4. What is the brand/model is the best underfloor heating?

pipe system (water) is alot of work to install. Electric system costs more to run. Depending where installed and what floor covering is installed, yes it can breed bacteria at a faster rate. Also it takes longer to give out heat or stop giving heat depending on how installed. ( if your too hot and you turn it off, it will keep on giving heat for a couple of hours!) Also you cant just turn on or off as you please as it can cause damage to the floor covering installed on top
