4 Things to Know Before You Build Your Own Heat Pump System
A heat pump system is used to heat and cool your home and can effectively replace air conditioners and central heating systems. Installing a heat pump system is a green way to approach home heating and cooling. The process moves heated air from a single source which is at a lower temperature (cool) or higher temperature (heat) to a heat sink at another location. The heat pump system chooses which coil to use by switching a valve, either supplying heat or cool to your home. There are several things to consider prior to building a heat pump system on your property and the following article will share some of those with you.
1. More than Efficiency
The whole point of installing a heat pump system is to save money. In addition to saving you money by providing a more inexpensive way (over time) of heating and cooling your home, they are also energy efficient. Above of all of this, the units are also being made to be more environmentally safe than their air conditioning or central air counterparts. A heat pump system can be expensive to install, so make sure to ask the salesman about costs associated with installation. Also inquire about any warranties you may add to the purchase and what they cover and do not cover. Getting all of the answers from the start will help you choose the best heat pump system for your needs.
2. Know SEER and HSPF
When considering a heat pump system, very often you will encounter acronyms and numbers you will not know. The most common are SEER and HSPF, which are designations of the Department of Energy, and all heating and cooling systems are required to have them. These are the ratings from the manufacturer, based on the standards set by the Department of Energy. SEER is the Seasonal Energy Efficiency Rating, and is found on air conditioners, while HSPF is the Heating Seasonal Performance Factor, for heat systems. The heat pump system uses both. The price of the unit is largely determined by these ratings. The higher the number for SEER or HSPF the more efficient the unit, and efficiency equates to cost. The more efficient a heat pump system is can also increase the value of your home.
3. Exterior Case
The encasement of the heat pump system is important, as it directly impacts the life of the unit. Make sure that the condenser is enclosed in galvanized steel. The paint of the cabinet is also important, because you do not want it flaking or chipping off. It should be a high-quality enamel powder-coat, so it will withstand the elements.
4. Coil Materials
The last thing you want to do is spend a lot of money on a heat pump system just to realize you bought one with substandard materials. The metal that makes up the condenser and evaporator should be copper, because it's a great heat conductor. It also stands up to corrosion. Aluminum is much cheaper, but will corrode and you'll lose heat from the system, which can cost you more money.
