HOW IT WORKS

The technology behind a New England Solar Hot Water thermal system.

HOW OUR SOLAR THERMAL SYSTEMS WORK

A NESHW ‘New England Drain Back’ appliance provides environmentally friendly heat for household hot water. Although the system initially costs more than conventional water heaters, the fuel it uses – sunshine – is free.

The main components are: the solar collectors, the storage tank, pump and controller package, and an insulated line set that runs between the collectors and the storage tank. In most cases, your existing hot water heater will serve as back-up for when there is no sun or very high household demand. If your old hot water heater is in need of replacement, the NESHW solar hot water system can include integral electric backup with an electrical immersion element in the solar tank.



STAINLESS STEEL TANK

Durable enough to last as long as the system – about 20-25 years!



HIGHEST COLLECTOR RATING

We choose to work with Kingspan flat panel collectors, which generate the highest possible MassCEC rebate.

DRAINBACK DESIGN

Designed to prevent overheating in the summer, freezing in the winter, and expansion tank failure.



VERSATILITY

Our systems can work in conjunction with an existing non-solar hot water system, or as a standalone system.



PRICE

Most residential installations will cost about $5,000 or less after tax credits and rebates – a price that none of our competitors can touch!

Bright sunshine is not necessary for your system to work. On cloudy days and in hazy conditions there is usually sufficient solar energy for the system to provide the required amount of heat. Moreover, our collectors have very high ‘cloudy day’ ratings and work extremely well in New England and will still provide hot water on the coldest winter day.

On some occasions such as prolonged overcast periods or when your hot water demand is very high, the back-up heater will kick in and ensure that you always have hot water. In most homes, the solar collectors will provide about 70 to 90% of your hot water year round with the ’back-up’ providing the rest.
