Understanding Solar Water Heater Controller

A solar water heater controller is the heart and brain of a solar water heater. It is something that controls the flow of heating fluids and water, depending on programmable temperature differential measurements. A solar control system helps in temperature measurements in different zones like the output of the collectors and compares it to the solar storage tank.

However, a solar water heater control system makes a decision to turn off or on pumps and diverter valves. It can display the current status of the solar control system and make adjustments ensuring your safety. In fact, solar water heater controller can connect the system to a user’s PC or iPhone remotely.

There are three main parts of a solar control system that are discussed below:

Digital Controller –

A Digital Controller comprises of a differential computer that comes with temperature input sensors and output relay controls. The digital controller will switch on the pumps when there is a demand of heat from the collector and divert heat to an auxiliary heating system. It will shut down the system if the heat demand is too low or too high in emergency situations.

Mechanical Pumps and Diverts –

Mechanical Pumps and Diverts comprise of the components that move and control water or heating fluid physically. It comprises of pumps and electronic diverter valves that are used to control the flow in a solar thermal system.

Specialty Plumbing System –

Specialty plumbing system is often overlooked feature. But, it’s important to safe and efficient to operate a solar thermal system. These are important specialty plumbing requirements that are important for a proper operation of solar heating system, including:

• Safety features, like pressure release valves, one way flow valves and expansion tanks
• Service features like the fill and drain valves as well as shut down valves
• Operating regulators including pressure display, flow meters, hot and cold temperature valves
• Maintenance features like air bleeding scoops

Fortunately, there are solar control systems that combine all three components into a compact pre-assembled system. This makes the installation fast and eliminates the chances of failures as well as improper installations.

However, Northern Lights utilizes PAW solar flow stations with RESOL DeltaSol computer controllers for all of their systems. These German engineered systems have been used over 2 million solar installations around the world.

This is why Northern Lights stands out as the industry’s leading supplier of quality solar components and controllers. Their proven track record means that you can be assured of having the best system available on the market. However, the solar water heater controller comes with a pump station. The pump station features the following:

Airstop

It’s specifically designed to de-aerate the solar fluid for the installation of solar systems. The optimal installation point is in the collector flow and the solar valves as well as fittings. It’s accessible for servicing during operation.

The airstop offers high de-aerating output due to low viscosity at high temperatures of the solar fluids in the flow and the big volume, minimal flow velocity and long storage period. The air separated from the solar fluid collects in the airstop and can be vented from time to time. It uses stainless steel corrugated pipes and can be completely vented.

High Temp Flow Valve

A high temp flow valve has brass fitting for high temperature and ensures the flow of the system only one way. It prevents anti-siphon causing due to thermo-siphoning in the evening. Manual temperature gage with service valves ensures quick servicing without draining the system.

Flow Meter

Superior quality Bora Silicate glass flow meter comes with service valve that ensures precise flow circulation. An adjustable flow valve ensures micro calibration of flow.

Bottom Line –

If you want to know how the solar water heater controller works, please feel free to contact your solar water heating specialists today and they’ll help you out. You will get a better understanding of the solar water heater controller and they will get back to you as soon as possible.
