1. System  inspections, reports and appraisals.

"Does it work or does it not work", that is often the first question prospective  owners ask  when purchasing a property  with an existing solar heating system.

 ESDI's team of professionals can  inspect and provide a detailed analysis of your property's solar/gas water heating system.  Standard prices are  $90 for residential and $150 for commercial.  We also provide annual  preventive maintenance programs starting at $175 per system.

2.    Tank relining or replacement.   The solar storage tank is probably the most frequently neglected part of a standard solar hot water or thermal heating system.    As recommended by most manufacturers, tanks – especially in commercial applications – should be inspected on a regular basis.

Commercial ASME tanks can generally be drained, flushed, cleaned, inspected and have a new  gasket installed  within one working day.  Inspections can determine the condition of the existing lining.  Service may be recommended.      Glass-lined line tanks, for instance, may require new anode rods.  Slightly cracked concrete-lined vessels may require "grind, chip and touch up" with a skim coat  of Pre-Krete tank lining formula.   More severely worn linings such as those often found in phenolic or epoxy-lined tanks may require a complete "stripping and relining" with Pre-Krete.

Lining a water storage tank with Pre-Krete will extend its useful life dramatically.  Environmental Solar is the Southern California distributor for Pre-Krete.    Patterson-Kelley, an internationally recognized manufacturer of water heaters, warranties its factory-lined tanks for 20 years.   Patterson-Kelley is a division of Harsco, Inc.    Pocono Fabricators, a division of Patterson-Kelley, has been producing Pre-Krete (www.prekrete.com) for over 50 years.  For a short history of water-tank lining here in the United States, see Boileau's history.

When a  tank has been neglected too long and leakage is beyond repair, Environmental Solar can provide replacement vessels.

3.  Reroof  and Racking Systems.
From the early l980's, Environmental Solar has been installing its solar systems with an eye to making its installations as "roof-friendly" as possible.

Our all-metal racking elevated "standoffs", or roof attachments, have saved our clients thousands of dollars  in reroofing costs.     Let us know if we might be able to do the same for you.

4. Gas hot water heaters, boilers and controls.

Most solar hot water heating systems preheat water for a fossil fuel gas, electric or propane back-up heater.  In this sense,  most solar thermal systems are a hybrid of unit of alternative and fossil fuels and require a dual expertise to maximize the efficiency of both.
