The key to real savings is a system that works year round.  Hot water consumes a large percentage of the energy required for any residence.  With today's utility prices rising at record rates with no end in sight, now is the time to switch to a solar hot water system.  CALL US TO START SAVING NOW! 

NEW NEWS - IF YOU ARE A NATIONAL GRID CUSTOMER (OR WANT TO SWITCH TO NATURAL GAS), YOU MAY BE ELIGIBLE FOR UP TO $1500 IN REBATES TOWARDS A SOLAR DHW SYSTEM.

Pricing - Domestic Hot Water

An average system would cost approximately $9,900. This includes all parts, materials, and labor.  Federal and State Tax Credits can reduce that num­ber by approximately $5,445, resulting in a net cost of only $4,455.  *NATIONAL GRID CUSTOMERS MAY BE ELIGIBLE FOR A 15% REBATE (UP TO $1500) TOWARDS THE INSTALLATION COSTS. At current oil rates, annual savings in energy costs would be about $835 (based on 5 people in the home). That's an 18.75% tax free return on your investment!!

Non-Pressurized Drain-back Systems

A small drain-back reservoir is installed in the collector loop. This system is filled with water only to the top of reservoir. Since it is located below the collectors, they remain dry when the pump is not circulating. When the collectors are hotter than the water in the storage tank, the pump circulates the water in the reservoir through the collectors where it is heated. The heat from this water is then transferred to the solar storage tank through a heat exchanger located in the storage tank. As the collectors and the solar tank approach the same temperature as determined by the differential controller (thermostat) the pump shuts off and all the water drains back to the reservoir. Every night when the solar control is satisfied the system shuts off and all the solar water is drained from the collectors back to the drain back tank. This also provides freeze protection in the winter because all the water is drained from the collectors at night.

Pressurized Glycol Solar Heating Systems
The solar collectors heat the glycol which is circulated down to the heat exchanger in the solar storage tank. Heat is then conducted thru the walls of the copper heat exchanger to the water in the solar storage tank. The averace temperature in the solar tank in the winter is 80 to 100 degrees.. During the summer months the temperature in the solar storage tank is typically 120 to 140 degrees and can reach as high as 160 to 180 derees under certain conditions. The daily operation of the system is handled by a solar control (thermostat.) The solar fluid we use as the heat transfer medium is a high temperature, non-toxic, food grade propylene glycol. It is used as a miostner, sweetener, and preservative in many of the foods and cosmetics we use every day. Using propylene glycol as the heat transfer fluid reduces the chance of the possible freeze damage to the solar collectors during the winter months.
