Solar Heating

Doing it right the first time.

BTU: British thermal unit.
Means how long it takes lbs of water to raise one degree. Heating and cooling are all based on Buts’. There are 12,000 btus per one ton of air conditioning.

SEER: Seasonal energy efficiency rating.
This is the rating residential equipment was given to help home owners understand what they are buying. They take the amount of watts used between the indoor and outdoor equipment and divide it by the btus of cooling then divide it by the average run time of cooling in an area to provide an explanation on how efficient the equipment is. At this present time 13 SEER is the min rate allowed.

COP: Coefficient of operation.
The ration of how much energy you need to put into a heat pump to the amount of btus it will provide based on the compressor and the indoor coils.
