4 Best Residential Solar Hot Water Heaters

Primarily, solar hot water heaters are used for heating water at homes and business. The energy consumption at home includes around 20-40% from hot water. Obviously, you’re looking for a way to minimize the expensive energy consumption costs. This is where solar water heater comes in.

Northern Lights solar water heaters are able to reduce hot water cost by 65-75%. These DIY solar water heating kits are easy to install and come with components to complete the installation. Generally, they use special stainless-steel solar piping and fitting rather than complicated and complex soldering and pipe work.

Here are a few types of solar hot water heating systems that are worth considering for residential hot water:

1. Pre-Heat Solar Tank System 

The Pre-Heat Solar Tank System comes with two tanks – solar pre-heat tank and a solar hot water storage tank with an internal heat exchanger for water heating. However, the solar pre-heat tank system is used to supply warm water to your existing hot water tank.

This type of solar water heating kit is the common retrofit as it utilizes the existing hot water tank and requires very little retrofit to the plumbing system. The existing main supply line is routed to the pre-heat tank and drawn back to the supply line after it gets heated.

This solar water heating system utilizes the stratification principle. In this process, the solar heating kit is heated using thermosiphon. It ensures mixing water slowly which results in hottest top layers. Though the top water draws into the main tank, the hottest water is first used.

2. Solar Tank-Less Water Heaters

The principle is quite similar as the water gets heater prior to the solar storage before entering the tank less heater. For example, the water coming from the main line into home at 40 degrees can be heated in a pre-heat tank and if the tank less heater is set to 140 degrees, it supplies 20 degrees of heat energy – which ensures significant heat savings.

3. Solar Combo Tank System 

Solar Combo Tank System is a specially designed kit that combines a solar pre-heat tank and electric backup heater in one unit. This tank utilizes an internal heat exchanger present in the bottom part of the tank.

The solar loop is piped throughout the loop and heats up water. The top part of the tank has an electric heating element to attain the water temperature quickly or aide during the days without sun.

Important Note – While there is a huge availability of solar storage tanks with heat exchangers, there are a few systems designed specifically for the North American Market. They have proper UL certification. The Solar Combo Tank System is perfect for installation at new home or if you want to replace the existing solar water tank.

4. Solar Compact Water Heater 

Solar Compact Water Heater is ideal alternative to those looking for solar heating systems at home. It’s perfect alternative to more advanced closed loop solar water heating system and has no moving parts or pump.

This system works perfectly in southern climates that seldom get freezing conditions and is good to work in 20 F temperatures. Solar Compact Water Heater generally sits on the ground or gets mounted on the roof. The 80 gallon storage tank is integrated with solar evacuated tubes and provides hot water to a family of four to five people.
