The transference of energy from point a (heat source) to point b (needed delivery place). There are 4 different ways of doing so.
1. Is with moving of tempered air through large ductwork.
2. Moving of a liquid through pipes to a energy defuser of said energy
3. Radiant heat; like a heating element heating an oven or a fireplace heating a room or the sun through a window heating up the room in the wintertime.
* Forced air: This is the cheapest way to install a heating system with the poorest way of heating the objects in the house. With some manual and electrical parts running the system. When the furnace fan turns on it blows cold air for a couple of minutes until the ductwork gets warm. Then it delivers the needed warm air for warming the ambient air in the room. Once the room temperature is reached, the air passively warms the items in the room. Starting with the ceiling and upper walls of the room working its way down to the floor.
* When it comes to cooling the forced air system works the best. I takes a powerful fan to drive the cold heavy air to the top floor allowing it to cascade downward cooling the item’s it come in contact with. This means the floor will be the first large surface to be cooled than slowly it works it’s way up to the level of the thermostat. You will still have a lot of hot and humid air at the ceiling if the heating contract did not install a high wall return air duct.
* It’s also the best and I think the only way to really clean the air, removing air born allergens out of the air. You can use secondary air filtration units but the biggest one I’ve seen only does 1 room at a time trapping a person with allergies in 1 room or in 1 area of a house. Using a high quality air filter on your furnace (they can be Paper) about 5” thick do a great job of cleaning all the air for the entire house.
* Hot water heat: Is a good way to heat a house. With a boiler you convert fuel into hot water. With this type of system you can do multi-tasking of different types of jobs at the same time.
* Such as using radiators to heat the air, in-floor heat to heat floor surfaces such as front & back entry floors to melt the snow and evaporate the water or heat the bathroom floor and even heat the sidewalls of your shower to make your shower a better experience for you.
* With in-floor heat you can heat the basement floor that is the hardest surface to heat, while using hot air blows above the floor it will never actually heat the concrete floor. But having the pipe in the floor, the floor becomes a large radiator heating the room, making the enjoyable, instead of saying well we have a basement. Whats so nice about in-floor heat you have no moving air or cold drafts moving across the floor.
* The next area to heat with the hot water is the garage floor your car will love it the snow and ice melt off of it quickly taking with it the salt. Using a forced air blower in a garage is nice but the floor all ways stay cold and if you in your garage a lot you differ projects on till the warmer months of the year.
* And finally you can heat your driveway and sidewalks, think about you newer have to lift a shovel again.
