It all depends on the size of the house, how well it is insulated, the outside temperature, and the inside temperature. For most houses about 20 kW should be enough (say 75,000 BTU/hour)

How much energy does it take to melt ice?
Heat because Ice and water would thaw out and begin to heat up
What is the ability of a substance to absorb heat energy is called?
Specific heat capacity describes how much heat energy that is needed to raise the temperature of material.
What is the measurement of how much heat energy is required for a substance to melt?
heat of fusion
What is a slankey diagram?
The diagram below shows a picture of a slankey diagram. Energy is weighed in kj (kilo joules). the electrical energy represents how much energy you started with. The light energy represents how much energy you used for the lights. The heat energy represents how much energy you did not use for the lights but you used it for heat.
If 30.86g of H2O is frozen (from liquid to solid) how much heat energy is required?
No heat (energy) is required to freeze water (from liquid to solid). Freezing RELEASES energy (heat), as it is an exothermic event. If you want to know how much energy is release, you need to know the heat of fusion for water, and then multiply that by the mass of water being frozen.
How is energy conserved in mud houses?
The mud house is less compact than the brick + cement house and on absorbing solar energy, the mud house does not oscillation much and probably, the air trapped in mud house walls may be insulator but bricks are more conduct of heat. So not much heat is passed in building in mud house.
How does a green house keep earth from losing energy?
A green house is a structure primarily Glass which temperature and humidity can be controlled for the cultivation or protection of plants.A green house keeps earth from losing energy because it does not let in to much heat or to much cold that's how a green house keeps earth fro losing energy.
What type of energy is heat?
Heat is thermal energy. It is pretty much the same thing as thermal energy.
How much the temperature of a material is changed by heat energy depends?
It depends on the amount of material (its mass), on how much heat energy is added, and on the material's heat capacity.
In a 60 watt light bulb how much energy is converted into heat?
What are the uses of Heat energy
What causes is too much heat?
There is no such thing as "too much" heat. Heat is a form of energy it just IS. If something is too HOT then an excess of heat energy has been applied for the purpose intended.
What is the difference between heat and temperture?
Heat is the AMOUNT of energy, Temperature is the CONCENTRATION of heat energy. For example; An iceberg (a big one) will have more heat energy than a cup of coffee (fresh and hot).
How much energy does it take to melt ice?
Heat because Ice and water would thaw out and begin to heat up
What is the ability of a substance to absorb heat energy is called?
Specific heat capacity describes how much heat energy that is needed to raise the temperature of material.
What is the measurement of how much heat energy is required for a substance to melt?
heat of fusion
Use of fireplace to save energy?
Using a fireplace means you don't have to use as much heat in your house, as they fire also produces natural heat. Heating hosues takes fossil fuels and energy, so having some heat come from a fireplace means that less heat has to be taken from natural resources like oil and coal.

The diagram below shows a picture of a slankey diagram. Energy is weighed in kj (kilo joules). the electrical energy represents how much energy you started with. The light energy represents how much energy you used for the lights. The heat energy represents how much energy you did not use for the lights but you used it for heat.
