A 4 ton heat pump should be fine, depends on how well your house is insulated. If the house is well insulated you might be fine with a smaller unit.
The heat generated by 1700 joules of work depends on the efficiency of the process. In an ideal case where all the work is converted into heat, the heat generated would also be 1700 joules. However, in real-world scenarios, the heat generated would be less due to energy losses.
You will have to have an engineer spec that beam for you. You will save yourself time and money by cutting the span with a column.
The heat shields on the Cherokee models are needed. The floor pans in the Cherokee models are thin and are penetrated by heat very easily. If you have driven one much, you will notice that the drivers and passengers front floor pans get quite warm from the engine heat. This is true with the muffler also. If it is not shielded the floor will get really hot and penetrate into the cab.
my 1998 gmc jimmy has no floor heat but i have defrost and ven heat
It allows you to walk (with out friction between you and the floor this wouldn't be possible) It is needed for braking can be used to produce heat
the heat blows out the defrost when it should blow out floor vents only
it depends of your house. if it has more than one floor then it might not. it also depends on how many rooms has radiant floor
Radiant floor heat is considered by many to be better than central heat because it is much better for our environment. Another reason is that is cost less to heat your house using radiant floor heat than central heating.
The floor you can install on top of the radiant heat is Tile and hardwood floor.
Heat can be lost through the floor by conduction, where heat moves from a warmer area to a cooler one through a solid material like the floor. Additionally, heat can also be lost through the floor by air leakage or infiltration, especially in areas where there are gaps or cracks in the flooring that allow warm air to escape and cold air to enter. Insufficient insulation beneath the floor can also contribute to heat loss.
The second floor of a building is often hotter than the first floor because heat rises, and the second floor is closer to the roof where heat gets trapped. Also, the second floor may receive more direct sunlight or have less shading compared to the first floor, leading to higher temperatures.
A marble floor feels hotter in summer than a carpeted floor because marble conducts heat. Since the heat gets trapped, it travels to the rest of floor raising the temperature. Carpet does not conduct much heat due to tiny holes that allow air ventilation.
