Understanding Different Types of Solar Water Heaters

by Northern Lights Solar Solutions Supplier of Solar Energy Systems in Canada

Northern Lights solar water heating kits are designed perfectly to deliver accurate ROIs as well as performance guarantee. Their solar heating packages are easy to follow and the instructions that will be given make it really easy for any DIY to install without any previous knowledge of solar heating experience.

Here are a few reasons to consider installing solar water heating kits:

The solar water heaters are quick to install without soldering and electrical work, offering the Plug n’ Save operation.
This water heater is designed and sized for optimal performance and reliability utilizing the custom-tailored simulation software.
All of the water heating packages are factory-ready to be expandable to secondary heating applications like solar pool heating or solar home heating.
All the systems are pre-engineered using Zimlet High Temperature Solar expansion Tanks, manufactured in Italy. These tanks are certainly designed for solar heating purposes with high temperature EPDM rubber bladders.
The solar heating packages are available at cost-effective prices and the installation cost is around half of a traditional solar heater/

Pre-Heat Solar Tank System

Pre-Heat Solar Tank System comprises of two tanks – a solar pre-heat tank and a basic solar hot water storage tank. The solar pre-heat tank supplies hot water to an existing water tank. This water heating is the most common retrofit as it utilizes the existing water tank and requires very little retrofit to the plumbing.

The existing main supply line is routed to the pre-heat solar tank and drawn into the supply line after it gets heated. The solar water heaters are most efficient and use the basic stratification theory. In the stratification principle, the solar water heater gets heated utilizing thermosiphon or a very slow pump.

This slow mixing of water results in the hottest top layers. When the top water is drawn inside the main tank, the hottest water is always used first. On an average households use hot water in batches and the solar water heating system can supply daily demands easily.

Solar with Tankless Water Heaters

In this water heating system, the water is heated prior through the solar storage tank before entering the tankless heater. For example, the main line water which comes inside home at 40 degrees can get heated in a pre-heat tank to say 120; if the tankless heater is set to 140 degrees, it has to supply 20 degrees heat energy versus 100 degrees without a pre-heat tank. This way, you will get heat savings significantly.

Solar System with Combo Tank

This solar system is a perfectly-designed solar pre-heat tank with an electric backup heater. The tank utilizes an internal heat exchanger in the bottom of the tank. The solar loop is piped through the loop and heats the water. The top part of the solar tank contains an electric heating element to quickly top up the water temperature or support during the days without sun.

Though there’s an availability of solar pre-heat tanks with heat exchangers, there’re very few that are specifically built for the Northern American water heating applications. They come with the UL certification. However, solar combo tanks are perfect for new home installations or if the existing water tank needs replacement.

Compact Solar Water Heater

A compact solar water heater is ideal for those who are in need of solar heating for residential hot water purposes. It’s considered to be the great alternatives to the more advanced closed loop solar water heating systems. This system works well in southern climates that seldom get freezing conditions and work good at 20 F (-5 C).

The compact solar water heater usually sits on the ground or is roof mounted. There’s an 80 gallon storage tank integrated with solar vacuum tubes. It is capable of delivering hot water for a family with 4-5 members.

Final Consideration –

When you’re on the market to shop for the solar water heaters, you should understand your needs and do a thorough research on solar water heating kits. You should make a right selection for your requirements.
