Split solar water heater kit overview

There is no doubt that solar energy is currently among the trendiest things in the energy sector.

More people across the world are embarrassing solar water heaters for homes and commercial use.

Among the different types of solar-powered water heating systems is the split solar water heater which is also known as a half-cut solar water heater.


Although it is among the rarest types of solar water heating systems, it still holds some significant percentage in the water heating market.


Are you considering to buy a half-cut solar water heater? We have a perfect guide for you.


Read on as we explore everything you should know about the split solar water heater.


What is a split solar water heater kit

solar water heater kit is a type of solar heater whose components are not combined in one. Instead, the components are split into different positions.


A typical split water heater has solar collectors installed on the roof while the tanks are inside the house.


In this type of solar water heater, heat is transferred from the collector to the tank by natural convection or by the help of a heat pump thanks to the heat transfer fluid.


At the end of the process, the tank will be completely heated and ready for use.


Split water heaters can be used for both domestic and commercial purposes.


Components of  Water Heater heater kit

Like an ordinary solar water heater, split solar water heating system comprises of different components.


These are:

-Solar collector/screen


-Circuit connector

-Flow rate indicator

-Pump and pump-speed adjust switches

-Wall mounting system


As you can see from the list, these are basic components only that some additional components fit the specification and working operation of the split water heaters.


Split solar thermal collector is responsible for collecting heat that is needed to make the water warm. It is designed and manufactured to maximize the amount of heat that it absorbs from the sun.

It features a reinforced glass that prevents the radiation from escaping.

For the split solar water heater, there is a heat transfer fluid that transfers the heat from the collector to the water tank.


Heat pump is responsible for pumping the heat transfer fluid to the water tank. The fluid will then release its heat to the water and then flow back to the tank. A pump is powered by electricity from the mains though you can be smart enough to use solar panels.


Heat flow meter Measures the heat output from the split solar water heating system. You will need the value from the manometer to gauge the overall performance of your solar water heater.


A controller is responsible for regulating the flow of the heat transfer fluid. It ensures that the heat transfer fluid circulates to the areas of the collector where there is sufficient heat.

Most controllers are automated even though some are manually operated.


Hot water tanks for the split solar water heater exist in different forms. The tanks are designed depending on what you want to use water for. In most cases, the tanks are made of stainless steel due to its numerous desirable thermal properties.

A tank usually incorporates a heat exchanger. The storage tanks also differ in terms of their capacity. Some are 200L while others are 500L.

How Split Solar Water Heater kit Work

While a split solar water heater kit can be identical to most solar heaters, it has a slightly different working principle to the ordinary heaters.


In a split system, water is circulated straight from the tank to the solar heater system with the help of an electric pump which is also known as a circulator.

The whole process starts off when the radiation from the sun hits the solar collector.

As the temperature of the collector increases, the circulator is activated. It is activated to turn on whenever the temperature of the collector is more than the temperature in the storage tank.

A circulator then pumps water from the solar collector to the storage tank and colder water from the storage tank to the collector.

The process will continue as long as there is solar energy or radiation and on the other hand, there is a need to heat water in the storage tank.

The circulator will deactivate when the temperature of the water reaches between 70 degrees Celcius to 80 degrees Celcius. The optimum temperature will depend on the split solar heater manufacturer’s specifications.

When solar radiation starts reducing gradually maybe due to the cloud cover, the collector temperature will start going down. The circulator will deactivate and the water heater will remain in a static mode.
