Backup Heating Options for Heat Pumps in Glendale, AZ

Monday, November 12th, 2012 at 8:29 am

Heat pumps are a great option if you want to have one system that both heats and cools your home. Heat pumps are also desirable because they are very efficient systems. But in extreme weather conditions, like during the winters in Glendale, AZ, heat pumps can actually become more inefficient. In this blog pots, we’re going to discuss why that happens and what the options are to account for that.

Heat Pumps in Extreme Cold

In heating mode, heat pumps move heat from outside into your home. Depending on the type of heat pump that you have, this can present difficulties for the efficiency of your heat pump. If you have a ground source heat pump, like a geothermal system, this may not be that much of a problem because the ground stays relatively the same temperature. But if you have an air source heat pump, which is very common in Glendale, as the temperature drops there is less available heat in the air. Depending on the model of heat pump that you have, that temperature can be between 30° F and 40° F. Other heat pumps can still operate at temperatures lower than 30° F.

Backup Heating Options

In order to supplement the work of the heat pump, some heat pumps need a back-up heating system. This system will work in tandem with the heat pump and, if it gets really cold, can completely replace the heat pump. There are a number of options available for backup heating systems. Here are just a couple of them.

Electric Resistance

Your toaster is uses electric resistance to generate heat. As a back-up heating system in a heat pump, these are called electric heating strips. This type of heat is generally very inefficient but can activate very quickly. They are also very easy to install when compared to a back-up furnace because they don’t need a gas line. Heating strips can normally be installed in the air handler and connected to a power source.

Back up Furnace

When you use a back-up furnace, the system is referred to a hybrid heat or dual fuel system. If you’re using propane, oil or natural gas for your home already, adding a furnace that uses one of those fuels won’t be that difficult. This is a great way to back up your heat pump.
