If you are far from these technologies, this article may help you learn what you should pay attention to when choosing a unit.

Tips When Choosing Solar Water Heater

When finding a contractor, every user first is explained on their site. It means that an expert will determine whether their household is fully suitable for installing the solar unit. Nowadays, most units are attached to the roof, however, it does not make every roof perfect for installation. So, either with finding a contractor or on your own, check the following:

  • Your roof should daily receive direct sunlight. Ideally, the sunlight should access your household between 10 am and 4 pm. The roof should face south and be sturdy.

If these criteria are not met, you will be recommended to go for a ground-mounted unit. Together with roof requirements, you should be aware of the standard classification of units. 

There is a direct and indirect unit. Direct units which are most well-known as open-loop systems work by circulating household water which is then used for shower or washing our hands. The water comes from the tank to the collectors and then goes back. An indirect or closed-loop unit works by using a heat exchanger to separate water from a heat-transfer fluid. The functionality may be quite complicated for users who are far from technology, however, indirect systems are more expensive – that’s what should be said. Beyond that, indirect systems are more reliable when it comes to very hot and very cold conditions.

Secondly, you should overlook your needs. By finding a contractor, you will be advised on the type and size of the unit which will fit your lifestyle. The steps determining the right solar water heater are the following:

  • Learn how units work, and what collector type may meet your expectations;
  • If you live in a cold climate, learn whether a preferred unit has protection against freezing – known as antifreeze;
  • Ask an expert about the batch systems if you live in areas with distinct winters;
  • By finding a contractor, you will learn the capacity of the unit suitable for your needs. 

Thirdly, by acknowledging the basics of solar heaters, you will need to understand the steps involved in the maintenance of the units. Again, you may access this information online which is based on standard units, or else by finding a contractor, you may agree to have regular checkups of your unit.

Finally, some experts do also recommend proceeding with a comparison of units. For instance, you have a preferred model and you are about to buy it. To ensure you do not miss other great options, you may compare two or three units based on their prices, functions, as well as warranty.

Finding a Contractor for Installation

If you decided to find a contractor to request help in choosing the solar unit, you should also take it seriously. The market of contractors is immense, and some companies may simply hook you on unnecessary services. For your acknowledgment, take a look at the following factors when choosing an expert:

  • By finding a contractor, ask them to provide you with cost estimates. You should have a basic idea of how much their services cost. Note, the final price is available only after the inspection of your site, and the unit you will install;
  • Learn whether a contractor has any references;
  • Depending on your area, a contractor should understand your local residential building codes;
  • Ask about the maintenance services. If you know that a solar hot water heater system is a hard nut to crack for you, you’d better learn whether a contractor may provide you with regular checkups to ensure the unit will serve you long.

That’s pretty it. By finding a contractor, you are deprived of any issues when choosing the right unit for your household. Furthermore, you receive top-notch service, while if you do everything on your own, you may come across unexpected expenses and much nerves.
