Choosing Active Closed Loop Solar Hot Water Heaters

Are you looking for one of the most affordable ways to add renewable technology to a home or a commercial building? If yes, then incorporating solar hot water heaters is significant.

Typically, a residential solar water heating system minimizes the requirement for conventional water heating by around two-thirds. As a result, the system reduces the cost of electricity or fossil fuel for heating water and the associated environmental impacts.

Solar hot water heaters provide you and your family with eco-friendly, clean energy for heating residential hot water, swimming pools, homes, and industries. Solar energy heats the fluid – water or glycol and transfers the solar heat directly or indirectly to heat water.

The initial cost of these systems can be slightly higher than the conventional gas or electric water heaters, but solar energy is free. In addition, with so many grants and low-interest loans available, a solar water heating system can cost less than a conventional heater upfront.

Solar hot water heaters can be of two types, i.e., active and passive. But the most commonly available are the active systems. They use heat pumps, while the passive solar water heating systems work on gravity or thermosiphon. Northern Lights Solar Solutions provides active closed-loop solar water heaters with pumps and digital controllers designed specifically for the solar industry.

However, solar water heating systems can do much more than just heat your hot water at home. Solar hot water heaters currently feature solar vacuum tubes that can be used for many applications like heating homes, space, commercial purposes, etc.

Solar-powered systems have become the rapidly growing alternative energy source throughout the United States and Canada because of government grants and low-interest loans. You should contact the Northern Lights Solar Solutions team and discuss taking advantage of solar heating systems and saving more dollars.

If you want a recommendation for a highly efficient solar water heating system, you should consider investing in an active closed-loop solar heater. It can be used for residential hot water, space heating, and commercial heating applications. The active indirect circulation or the closed-loop system uses a heat-transfer fluid, i.e., water or diluted antifreeze fluid, to absorb heat. The system has a heat exchanger to indirectly transfer heat energy to the potable water.

The heat exchanger helps transfer heat energy from the heated fluid to the potable water or the other fluid. In addition, some indirect heating systems feature an overheat protection bypass that eliminates the excess heat that can’t be used. The feature prevents overheating solar collectors and glycol fluid when there is a low load and high solar intensity of incoming solar radiation.

Usually, the heat transfer fluid used in these systems is a mixture of glycol and water, and glycol concentration depends on the expected minimum temperature. The glycol used is food-grade Propylene which is non-toxic. Typically, solar water heating systems are helpful for hot water heating and radiator or in-floor home or commercial heating applications. The system is close to the atmosphere but can build up pressure with increasing temperature. The solar hot water heaters incorporate pressure relief valves and solar expansion tanks for ensuring safety and protection.
