Solar Water Heater: Way Of The Future

There are several types of solar water heater systems: Passive vs. Active is one of the initial decisions to make prior to considering the 2-3 systems available in each category. A solar contractor is necessary to assist in choosing the system that is a perfect fit for each customer's individual needs.

A solar water heater system is a cost effective alternative to the traditional natural gas or electric water heater most homes use. While the initial investment of a solar system is higher in cost, and the installation needs to be done by a professional (standard water heaters can be purchased at a home improvement store), these appliances can save 50-80% in utility costs.

The Active vs. Passive question is one of the first decisions a homeowner will need to make. Passive is less expensive, is more reliable and usually lasts longer; but it is less efficient than an Active system. An Active system is more expensive and the choice between a direct circulation vs. indirect circulation system will need to be discussed (especially important for locations that experience freezing temps.) with a contractor. But these systems have proven to be more efficient than a Passive one.

When building a new home, a solar water heater system should be considered, so the cost of purchase and installation can be rolled into the mortgage payment. On average, this cost breaks down to $20 per month over a 30 year mortgage when added to the monthly payment, and with a Federal tax deduction for mortgage interest for a solar system, the cost reduces the payment by $5 per month.

There are several considerations to be noted before deciding if a solar water heater is a reasonable investment. How much water does the household use each month? Is the current water heater functioning optimally? The geographic location of the home & amount of exposure to the sun is a vital piece of information that will determine if solar is the way to go. And will a backup system be required for this home?
A contractor can answer any of these questions prior to scheduling the work to be done on the home. In addition to these points, an evaluation of the site is necessary to determine time, cost and solar resources in the area. Local codes, covenants and regulations will need to be investigated for each location, and then a budget can be set for the job.

Solar or Green energy is the movement toward a self-sustaining household many people dream of for their home. Going off the grid is a goal many individuals long to achieve, especially when the rising cost of fuels is taken into consideration. While this may appear a bit daunting at first, a professional solar water heater contractor/installer can answer all questions, from evaluating the home to applying for incentives to assisting in training a homeowner to operate and maintain their system.
