There are basically two times when you will need to consider purchasing a furnace for your home. In the first case, you are already living in a house with a furnace that dies and needs to be replaced. In the second case, you may be building your dream home and need to choose the appropriate heating system for it. Because buying a furnace is a significant and expensive proposition, it is important that you learn how to choose the best furnace from among the numerous possibilities. This is your opportunity to personally pick the best unit for your specific heating needs.
There are countless heating supply companies in the market who want to sell you your new furnace. Companies such as Carrier, Trane, Lennox, Goodman, Bryant, Rheem, Heil, and Coleman are just a few of the well-established businesses in this field. Learning how to choose the best furnace can be a real asset at this point. Most companies claim efficiency ratings of 80% – 97%. Some also offer optional features such as humidifiers, specialty filters and variable speeds. Within the furnace world there is also the matter of how the heating unit will be fueled. Electric furnaces; those with gas or oil burners; and coal, wood, or pellet indoor and outdoor heating units offer a broad, if not over-whelming, choice for the new buyer.
The recent surge in sales of outdoor wood furnaces has sparked interest on many sides. If you are still concerned with how to choose the best furnace, you will also want to consider this possibility, but only if you have a free or cheap and readily obtainable supply of wood or pellets.
Just like an indoor furnace, firewood heats warm water which is carried to the house via insulated underground water pipes.
The process is safe and can be economical. On the other hand, there is some concern that the emissions from outdoor furnaces are 20 times higher and may lead to respiratory and lung infections for those people living nearby.
If you choose a more traditional furnace, you are going to need to buy disposable filters or the newer replaceable ones.
BoAir sells a 5-Stage filter that has a lifetime warranty for about $75.00. It claims to reduce dust and allergens. Buying a furnace is an expensive investment. Knowing how to choose the right furnace by taking the time to research the matter thoroughly will help you make a good choice for years of satisfaction.
