Monday, July 6th, 2015

We live in Los Angeles, CA, which means we’re not afraid to color outside the lines sometimes. This can apply to your household appliances as well as more dynamic forms of creativity. Take your water heater for instance. Most people think of it as the dull-yet-dependable cylinder in their garage or basement, quietly doing its job without much fuss. It’s a dependable system, but it’s not the only one available. Tankless water heaters, though costing a little more to install, can provide numerous advantages over traditional models. We’ve listed three of those benefits below, which you should think about while considering installation.

Electric vs. Natural Gas: Which Is the Better Tankless Option?

Wednesday, February 4th, 2015

If you have decided to install a tankless water heater in your Pasadena home, you still need to make one more decision, and that is what kind of fuel you’ll use. There are two choices when it comes to fueling a tankless water heater: electricity or natural gas. Which one is best for your home? Let’s take a look.

Natural Gas

A natural gas tankless water heater requires access to a natural gas line. The installation costs for a natural gas tankless heater can be more than an electric one, but if you already have natural gas in your home, it may be a more natural choice. The main challenge with the installation of a gas tankless water heater is that the venting is very specific and complex, and many times most homes do not have the proper equipment for venting already present. This means that extra work may be required to install a gas unit. Gas units are very efficient, averaging about 85% efficiency, and can cost up to 15% less to operate than their electric counterpart.


Electric tankless water heaters are about 1/3 smaller than the tankless gas units because they do not need a burner; they also do not need access to a natural gas line and as such, can be installed without adjustment as long as your electrical box has the power to support it. Typically an electric tankless water heater needs to have an electric panel that supports 200 amps. If your electrical box isn’t large enough to support the tankless heater, you may have to consider an upgrade or using a gas unit. Electric tankless heaters have very high energy efficiency ratings, usually around 98%, because they don’t lose any latent heat in the form of combustion byproducts. They can also be installed as point-of-use heaters, directly under sinks.

Deciding which type of fuel will be best for your home will depend in part on your available resources and your needs. Working with an expert from AZ Air Conditioning and Heating from start to finish can help ensure that you install a tankless water heater in your Pasadena home that will fit your needs for many years.
