How many btu's in 4 foot hydronic baseboard heater?

You will need to give more information. The Btu's of baseboard is determined by the water temperature and the type and size of the element. Copper fin tube (copper pipe with aluminum fins over it) heats up quick and loses heat quickly it also has many diameters of element (copper tube). Most common in residential is 1/2", 3/4" & 1" ID (the OD will be 1/8" or so larger). There is also Cast iron baseboard that heats up slowly and cools off slowly (this is a much more even and comfortable heat). You should never mix and match cast iron radiation and copper radiation of the same circuit it will cause large temperature swings in conditioned area. Tell us what the boiler temperature is set to and what the type of radiation is and you'll get an answer.

You have 20 feet wide and 20 feet long floors you are trying to buy carpet for how much carpet should you buy?

Carpet comes in 2 widths 12' and 15' so if you go with 12' carpet then you need 2 pieces...to get it to the look the best with one seam I would get 2 20' pieces. 15' carpet I would order a 20' piece and another 6 foot piece ...that's given that the room is 20' exactly because you need to order extra 3 inches on each wall.. If there is baseboard heat against the walls you want to order enough extra carpet to wrap up and under for the best look. hope this helps

Can a water heater be used to supply water to baseboard heating?

Yes. You might want to check to see what recommended temperature is for water entering the baseboard units and insure the water heater will meet that. Something else to consider is that there will need to be a pump in the water circuit to circulate the water. A tank type water heater would also work to store hot water until needed by the baseboard units in an instance where heat might be generated at a time not needed by the baseboard units.

I think you need a pump; cast iron is not affected by the heat and cool (the clanging) cycle associated with gravity heat, but the new one might be, especially if it is copper tubing. Didn't they quit making those furnaces like decades ago?
