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.

Why Do You Switch to Compact Solar Water Heaters?

Are you looking for the most cost-effective solar water heating systems available? Perhaps you will invest in a compact or integrated solar water heater. The heating system comes with the same High-Performance TZ58 1800 Sun Rain Solar Collectors in all solar water heating systems available at Northern Lights Solar Solutions.

The compact solar water heater is specifically designed for residential water heating purposes. The system has the storage tank and heat pipe vacuum tubes integrated into a complete unit. The unit is SRCC certified to provide residential hot water for a family of four to five people by offering a heavily insulated 80-gallon stainless steel water tank.

Normally, the compact solar water heater is installed on roofing facing the south and is mounted on the ground with the 45-degree frame system. The system is straightforward to assemble and install. The cold water intake from the house connects to one end, whereas the hot water supply is connected to the other. The solar water heater has 30 tubes containing heat pipes inside the tank.

The energy transferred from the solar evacuated tubes to the heat pipes helps heat water and potable water directly. The hot water goes to the top of the storage tank, where it starts supplying hot water to the home. The compact solar water heater is considered a very efficient system and requires no maintenance.

The system uses a vacuum tube, a heat pipe, and a heat exchanger sealed internally. Hence, you won’t need to worry about the leakage and damage of vacuum tubes. Even if the tube is broken, you need to replace the vacuum tube with the new one, and the system continues working without one tube.

The compact solar water heater won’t require electricity

The compact solar water heater is a pressurized system and doesn’t require pumps. The water moves through the water heating system using the pressure of the municipal supplied water. While opening a hot water faucet, the hot water from the storage tank flows outside, and the cold water flows inside the tank, which will be again heated by the solar evacuated tubes.

The compact solar water heater won’t overheat

The compact solar water heaters feature a built-in air-release valve and the temperature and pressure valve that opens at 90 C or 194 F. When the system gets hot, it will simply vent off the excess amount of heat.

The compact solar water heater is made from stainless steel

The compact solar water heaters available at Northern Lights Solar Solutions have stainless steel internal and external tanks to prevent rusting. In addition, custom logos are available to label your water heater privately.

The compact solar water heater is cost-effective

This system costs only slightly more than an ordinary water tank. The life expectancy of the water heater is around double because no heating element or gas burner will fail. In addition, the water heating system provides you with a 30% federal tax credit and state tax credits.

However, the compact solar water heater doesn’t require a solar installer, as a homeowner or a general contractor can install it. The payback of a typical compact solar water heater is one to three years, and the payback period can be as little as three months with a solar water heating system in Hawaii.
