EAEER is a less frequently used but the most accurate energy efficiency ratio for air conditioning systems. Despite being seldom specified on the specs sheets, it is the most realistic air conditioner energy efficiency ratio (more than SEER, EER, CEER, IEER). EAEER stands for Energy Adjusted Annual Energy Efficiency Ratio. In contrast to more well-known … Read more
Starting in 2023, a lot of people started asking us what is the difference between SEER and SEER2 ratings. This surge in interest in the SEER2 rating is understandable. From 1st January 2023, all new HVAC units started listing SEER2 rating on their specs sheets. Here’s why we see a lot of these SEER vs … Read more
In HVAC, you will sometimes have to convert BTU per hour to horsepower (HP). This conversion is frequently used for air conditioner, furnace, or heat pump capacity. We are going to explain exactly how to calculate HP from BTU per hour. On top of that, we have also prepared a simple-to-use BTU/hr To HP Calculator … Read more
Horsepower to BTU per minute is quite a rare conversion since we mostly use BTU per hour in HVAC. Not to worry, though; we will show you exactly how to convert HP to BTU per minute for air conditioners, furnaces, and so on. Further on, you will also find an easy-to-use HP To BTU/min Calculator … Read more
In lots of cases, you see air conditioner capacity expressed in HP (HorsePower). We usually want to convert that HP to BTUs per hour. During this article, we will show you exactly how to convert horsepower to BTU per hour for an HVAC system (air conditioners, furnaces). On top of that, we have programmed an … Read more
If you use electric heating (electric furnaces, electric water heaters), you will naturally want to convert kWh to therms. We will show you exactly how to do it. On top of that, you have an easy-to-use kWh To Therms Calculator further on (just insert kWh, get therms). To top it off, we have converted 1 … Read more
MMBTU and therms are both units for heat content (usually for natural gas). It’s incredibly easy to calculate therms from given MMBTU. We will show you exactly how to do it. Further on, you will also find MMBTU To Therms Calculator you can freely use, as well as a chart with 0.1 to 10,000 MMBTU … Read more
Especially in colder months, a lot of homeowners want to know how to convert therms to MMBTU. This has to do with the use of natural gas for space and water heating (gas furnaces, water heaters). We will show you how to easily convert therms to MMBTU. To make things even easier, you will also … Read more
How much electricity do we get out of natural gas? This is the classic case when we would need to convert therms of natural gas to kWh (kilowatt-hours) of electricity.
