NEw ENGLAND <br />S ","LA R <br />hotwater <br />HOME I SCHOOL I BUSINESS <br />Mr. Mike Cronin, Director of Public Facilities 12 September 2022 <br />Mr. Martin Richardson, SED Associates Corp. <br />RE: Lexington Town Pool- Solar Hot Water <br />Dear Mike and Martin, <br />Thank you for your interest in our services. Attached is our proposal for your review. A couple <br />of notes: <br />NESHW has 15 years of experience in the field. Our business is primarily solar hot water <br />(SHW), and we have built over 900 residential scale systems as well as over 100 larger <br />commercial -sized systems. NESHW systems are unpressurized, glycol filled, and "drain - <br />back" design to avoid overheating, freezing, and over pressurization. Our general <br />philosophy is to use robust hardware including stainless steel or unpressurized tanks and <br />drain -back style systems to maximize longevity and minimize maintenance requirements. <br />With proper maintenance, the systems are built to last 20 years or more. <br />2. Our proposed solar hot water system would include (14) flat plate collectors and (2) new <br />solar storage tanks preheating a conventional electric resistance tank, thus reducing the <br />heat and electricity required from the conventional heater. <br />3. The price estimates include roof mounting of collectors and penetrations and installation of <br />stainless steel or copper insulated lineset piping to new stainless steel solar storage tanks <br />all to be coordinated with your staff and engineers. See below list of inclusions and <br />exclusions in our estimates: <br />4. INCLUDED: Complete system engineering, permitting, installation and commissioning: <br />collectors, storage tanks and all associated controls and hardware, NESHW basic and <br />manufacturer warranties, assistance with application for Alternative Energy Certificates <br />(AECs.) <br />www.NESHW.com <br />info@neshw. com / (781) 536 8633 <br />
