Repair Solar water heater

Whether you have a Viessman, Aquatherm brand solar pool heater, there will come a come when you need a repair, and eventually it will come time to replace the system. But how do you determine whether it is time to repair or replace it?

Solar pool heaters from major brands, including the Viessmann brand we offer, are warranted for years to the original owner. As a result, you would expect that they should last at least that long and replacement should not be due until the panels exceed 6 years in age. However, a variety of issues may bring you to the conclusion that it is time to replace your system before that time period. You may find that solar panel repairs involving non-warranty (not manufacturer defect) issues are becoming costly, and a new system with a new warranty is preferable.

THIS SOLAR POOL HEATER IS FALLING OFF THE ROOF AND THE PLUMBING IS BADLY WARPED. IT IS IN NEED OF REPLACEMENT.
The main reason you would consider repairing a system over replacing it is to resolve a minor leak. Repairing solar pool heating panel leaks is fairly straightforward. All brands have a preferred method of plugging panel body tube leaks. This is the most common leak repair and is quick and cost effective. Leaks in the header pipe of an individual panel usually requires panel replacement.
Leaks in the PVC pipe plumbing are also a reason you may consider a repair. PVC pipe is relatively easy and inexpensive to fix, and leaks usually occur at joints. In some cases, especially with black pipe, you may have warping, sagging, or burst pipes caused from stagnating water from improper drainage.
Panels that are causing roof damage due to sub-par installation techniques is a good reason to replace a system before damage becomes serious. PVC pipe or panel couplings digging into the roof membrane is a serious issue that we avoid using our exclusive roof protection system.
Improper or sub-par installation can exacerbate leak issues. Not following the manufacturer’s recommended installation method can result in catastrophic panel failure where replacement is really the only option. This usually stems from lack of proper substrate or racking systems under panels that require it.
When we are asked to evaluate a repair or replace decision, we look at the entire system. Plugging leaks in one place often leads to additional leaks in other areas in a short period of time. Chasing leaks is an annoying, frustrating, and costly course of action. A visual inspection of the system, how it was installed, the type and age of the panels, and other clues lead us to a recommendation to repair or replace a system. Often we are asked for a replacement quote when a simple repair is advisable, allowing a system owner to limp along with a very old system. Other times, what appears to be a simple leak could be an indicator of a larger problem that will continue to result in costly and repeated repair services.

If a system is older than 15 years, in all likelihood we are going to recommend replacement, but there are cases where panels can last substantially longer. Buying a new system with a new warranty and newer methods and products is something we ask people to consider any time we find poor installation methods and products. Throwing money at a system where there are other problems unrelated to the reason for a call is not a good idea. We will work with you to determine the best course of action in your situation.
If you do decide that replacement of your system is necessary or preferable, there are some important considerations:
  • What happens to the original attachment points? You definitely don’t want the contractor to use the same attachment points, which may have lost efficacy over time. More importantly, I can’t be sure that others did the job right. Sealing up the old attachment points, especially in shingle roofs, is critical to avoiding roof leak issues in the future. In cases where we are just removing panels, we usually leave the existing anchors and fasteners in place, as disturbing them is not the best course of action. That is not an option usually when replacing panels, so we have developed an exclusive method using flashing material and premium sealants to positively protect your roof when installing a new system.
  • You may need more or fewer panels to achieve desirable results. The original installing contractor may have undersized your system for pricing reasons or we may be able to offer a panel with better performance to reduce the required number of panels.
  • We never reuse plumbing and valves unless they are premium serviceable valves, 2 inch plumbing, and in pristine condition. There are very few cases where we reuse anything in the solar feed and return plumbing. You really want a new system, not just new panels.
  • If you have a working automation system, we can reuse motorized actuators and sensors to help keep your replacement cost down.

Irrigation Pumps

Image
Water supply is the first factor to consider when choosing a pump for outdoor use. Drawing water from ponds or rivers requires a submersible pump and centrifugal & turbine pumps are suitable for water supplies from the mains. Displacement pumps work like a piston and similar to old style hand operated pumps with a lever. These are useful only for highly viscous liquids such as fertilizer mixed with the irrigation water. Pressure and water flow rate are the next points to consider. It is  important to remember that the pressure will decrease when the water flow increases. A drip irrigation system can be attached to a lower pressure pump, spray systems require more pressure while rotary irrigation systems need the highest pressure. The required flow rate for any irrigation system is the sum of each required flow rate in the system’s sprinkler heads. Usually, the higher the flow rate, the greater the energy needed to power the pumping system. Irrigation pumps...

Why Some Storage tanks Crack

Synthetic or FRP storage tanks have evolved the warehousing of materials across the world. FRP storage tank manufacturers recommend their clients using storage tank for food, water, liquids, chemicals, and other materials. In this post, they will talk about the failures and preventive measures for plastic tank.  At manufacturing unit, you can find distinct types of plastic tanks in sorts of sizes and capacities. You can store from 100 liters of water to thousands of liters of other materials in the FRP storage tank. Manufacturers have made the life of their consumers easy by bringing this range of products. These tanks can be categorized into – Food and milk storage plastic tanks These tanks are food storage tanks and people use them for storing milk and food grains into warehouses. Food storing tanks don’t have large capacity and they are used for protecting food from moisture and fungal attacks. However, these tanks are hardly used for storing milk, but they do serve the...
