For anyone scanning this post, a solar powered water heater is definitely an object that makes use of solar heat, or energy from the sun, to heat up water to heat your house. The great thing relating to a solar hot water heater is always that the heat it uses from the sunrays will not be changed into electricity like solar pv panels, which is great for efficiency and then your electricity bill each month.
