Misol Solar Collector Of Solar Hot Water Heater

• Efficient water heating

• Does not come with installation instructions

Most solar thermal water heater systems are expensive. Many families cannot afford such systems even though the product will pay for itself in the long run. One of the most affordable systems on the market today is this MISOL product. The Solar Collector of Solar Hot Water Heater is a straightforward product that does a decent job of heating water for primary use.

The basic design of the MISOL is simple. You have a frame that can hold ten evacuated heat tubes. The manifold has an inlet and an outlet on opposing ends. You connect one end of your water line to the channel and connect the other end of the water line to the outlet. Water gets heated as it moves through the series of tubes. Simple and efficient.

Because of the simplicity of its design, one can use the MISOL for a variety of applications. You can use it to heat your water or even as an air dryer. It can also be a great training project.

We find it odd that MISOL did not include any installation instructions with the package. One must assemble the unit from scratch. Not that it can be tricky to assemble. Having instructions would reduce the amount of time of setting up the system. Also, the MISOL product is a passive system. Its performance is dependent on existing water pressure.

Solar Water Heating System Maintenance And Repair

Solar energy systems require periodic inspections and routine maintenance to keep them operating efficiently. Also, from time to time, components may need repair or replacement. You should also take steps to prevent scaling, corrosion, and freezing.

You might be able to handle some of the inspections and maintenance tasks on your own, but others may require a qualified technician. Work that requires going up ladders, walking on roofs, soldering or hot work, or cutting back tree limbs should be performed by a professional service for safety reasons. Ask for a cost estimate in writing before having any work done. For systems with extensive damage, it may be more cost effective to replace, shut off, or remove the solar system than to have it repaired.

How Do Solar Water Heater Systems Work In Orlando

Solar water heating is a technology works hand in hand with conventional heating systems and uses the heat absorbed from the solar panels to pre-heat the water in the storage tank.

Pre-heating the water with a solar hot water system can reduce the load on the conventional heater by increasing the water temperature up to a usable one. This effectively reduces the amount of energy the water heater takes, saves fuel, cuts back the cost of electricity, and prolongs the life of the water heater.
