Ogdensburg - United workers front recently a drain back solar hot water system on their McIntyre custom residential alternatives system installed which reduce costs and energy consumption.

 

Equipped with a 120 gallon storage for hot water, the building has used hot water now three solar panels on the roof for heating.

 

"There is to keep in mind when setting up on solar panels such as the size of collectors, Panel orientation, temperature, shade, and the roof and Panel pitch a lot," said Rick Pirie, Director of buildings and grounds at United helpers.

 

"Ideally, your roof should South aligned and the panels should be installed to cool down a few inches on the roof with sufficient air flow around them." Since the shadow is enemy number one of the solar energy, can the pitch or slope of the roof and get solar panels at the Sun, in an average day in the whole year. "

 

Advantages of drain back solar hot water system officials are sustainability and long-term efficiency incentives after United helpers.

 

The use of solar panels allows you to get a structure to energy from one another as a main power grid. Therefore there is no need, long power lines run. Once solar panels are installed, they can make up for their initial investments and are very low maintenance, say officials United helpers.

There are also a number of federal and Government incentives such as NYSERDA that want to install the solar panels on the offered.

 

Matt Bullwinkle of sensible solar in Potsdam was the central component for installation and financing, if it was a question, choose United helpers to solar hot water system go with a drain-back green.

 

"The drain back system at the McIntyre IRA used is durable, can be a building fits big or small, works in any climate, not freeze or Cook, is virtually trouble free, has only a few parts, and requires only a periodic maintenance" Pirie said.

 

"This system used a heat exchanger between the tank and the collectors also a glycol mixture, which has the highest heat transfer properties and they do not." Without heat exchanger between the tank and collectors, the system of 100 Drain% of the collector back transfers heat to the tank. "

 

Two temperature sensors control the solar system. One of them is the Hi-temperature sensor on the exhaust side of the collectors. The other is the Lo temperature sensor in the coldest part of the tank.

 

In the morning, when the solar collector temperature temperature rises to about 18 degrees warmer than the tank, the controller switches the collector pump.

 

Water is pumped from the bottom of the tank (the coldest part) through the collectors record heat how to do it. The heated water spills the return into the drain below returned tank.

 

The process continues as long as the collectors are at least five degrees hotter than the tanks, heating the tank continuously. At the end of the day, if the difference falls below five degrees, the controller switches off the pump and all the water flows back from the collectors in the tank.
