We now offer full service on Purist Solar Hot water systems (these are older systems and need maintenance and upgrades:

• We offer upgrades to your outdated Microsol II, to the new Microsol II E, Version 8.
• We offer installations of a new switch to turn the hot water on manually on cloudy days.
• We can install 2, micro LED's to display that the DC pumps are on.
• We can flush your system and put in new propylene glycol.
• We offer checks on the roof unit tubes to ensure no cracks.
• We offer replacement of both pump DC motors.
• We can fully computerize the system and have it use the Sitrad Pro software, using a FullGuage brand computer called Sitradinbox. This will give access to all the hot water data with a web portal on a computer or a phone "app." You can see live data on heating temperatures in your tank and the roof and make many excellent graphs with the software. Data can be downloaded into an Excel spreadsheet.
• Dana Fisher designed purist systems and was the company founder. He later became a key person in the "Efficiency Maine" program. Purist systems can last for decades if they are taken care of. We have these systems and have done all these upgrades, making it much more robust. Let me fix and upgrade yours!
