Solar hot water heaters
are generally helpful for heating hot water in homes and businesses.
Usually, hot water consumes around 20%-40% of the total energy
consumption of every home. Solar water heating systems are the perfect
solutions to minimize heating costs. However, Northern Lights solar hot
water heaters can reduce the hot water cost by 65%-75%. They are
easy-to-install systems and are available with every component to
complete the installation. These solar water heating kits come with
highly insulated stainless steel solar piping and fittings. They don’t
have any complicated pipework and soldering.
So,
go through the below-discussed water heating systems for residential
hot water. Please check out them thoroughly and make the proper
selection:
1. Preheat Solar Tank Water Heater
The
solar water heating system comes with two tanks. The first tank is a
solar preheat tank, whereas the second tank is the primary solar hot
water storage tank with an internal heat exchanger.
The
solar preheat tank helps supply warm water to the existing hot water
tank. This solar hot water heater is the commonly available retrofit as
it uses the existing hot water tank and requires very little retrofit to
the plumbing system. The current main supply line is connected to the
preheat tank and drawn back to the supply line when it gets heated.
The
Preheat Solar Tank Water Heating System works on the basic
stratification theory. In this process, the solar water heater gets
heated using a thermostatic or a very slow pump. As a result, it ensures
slow mixing of water, which means the top layers always contain the
hottest water.
Though
the water in the top part is drawn into the main tank, you will use the
hottest water first. This is because the average household uses hot
water in batches instead of all at once, and the solar water heater can
accommodate daily demands.
2. Solar Tank-less Water Heater
These
solar-powered water heating systems use the same principle. The water
gets heated through the solar storage tank and enters the tank-less
heater. For instance, primary line water coming inside the home at 40
degrees can be heated by using a preheat tank at 120 degrees C. If the
temperature is set to 140 degrees, it only needs to supply 20 degrees of
heat energy than 100 degrees without the solar preheat tank. As you can
see, you will take advantage of significant savings on heating costs.
3. Solar Combo Tank Water Heater
This specially designed hot water heating system combines a solar preheat tank and electric backup heater in a single unit. This tank uses the internal heat exchanger, which is present in the bottom part of the solar water storage tank.
The solar loop is piped through this tank and starts heating water. The top part of the water tank has an electric heater to quickly top up the water temperature or support during days of no sun.
4. Compact Solar Water Heater
Are you looking for a solar heating system to produce hot water at home? Then, why don’t you invest in a Compact Solar Water Heater! It’s an excellent alternative to the advanced closed-loop solar water heaters and has no moving parts or pump.
The
Compact Solar Water Heater system works very well in the southern
climates, which seldom get freezing. It works up to 20 F (-5C). You can
install it on the ground or mount it on the roof. An 80-gallon storage
tank is integrated with the solar evacuated tubes and provides
sufficient hot water for a family of four to five.
