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.

The cost of pool heating system is less that yields homeowners more savings over electricity and fossil fuels. You will have much larger savings than any other type of solar pool heaters.

Investing in Solar Vacuum Tubes Pool Heating Systems –

You may be aware of the leaky plastic mats used in the roofs of pool owner’s homes. Currently, the new age solar pool heaters are available and are equipped with powerful vacuum tubes to deliver solar heating energy to the pool in an indirect way.

This pool heating kit uses a stainless steel or a titanium heat exchanger to eliminate harmful damage caused by the chlorinated water on any solar heating system. Though it uses heat exchanger, it won’t need any oversized pumps to raise the water volumes to the top of the roof. Instead, the system requires a small circulating pump that draws less than a light bulb and has a life expectancy of 20 years.

Why Do You Purchase Solar Evacuated Tubes Pool Heaters? 

There are numerous advantages of using solar vacuum tubes for heating a pool. Here are some of them discussed below:

• A vacuum tube works in indirect light and cloudy conditions. This means, the pool heater is capable of delivering usable heat energy to pool from sunrise to sunset and cloudy days.
• Evacuated tubes have a life expectancy of over 25 years. Therefore, you don’t need to fix leaks and replace mats in every three to five years.
• The overall cost of a vacuum tube is substantially lower.
• Evacuated tubes remain intact during harsh windy conditions.
• The ordinary plastic pool heaters work like radiators that remove heat energy faster than it can be supplied when there’s even a slight breeze. Vacuum tubes work in -40 degrees. When the ambient temperature is cooler than pool water, the solar water gets working. Other pool heating systems provide heat when the air temperature is greater than the temperature of the pool.
• A pool owner can extend their pool season by two to three months by using solar evacuated tubes pool heaters.

How Do You Design Solar Water Heating System?

Understanding Solar Water Heating System - 

 

Since the late 1800s, most commercial premises have been using solar hot water heating systems. Over the years, the solar water heating has evolved drastically and currently, these systems are powered through solar vacuum tubes ensuring optimal efficiency and maximum performance.

 

It’s estimated that around 200,000,000 solar water heaters (https://www.solartubs.com/) are available around the world and the Asia leads the way whereas Europe comes the second. Out of all the available solar powered heating kits, Northern Lights solar water heating system tops the list.

The heating kit uses an active loop technology that enables indirect way of water heating through close loop. An internal heat exchanger is present in the bottom part of a specifically-designed solar water storage tank.

The system comes with sophisticated solar differential controllers, capable of maximizing system performance. On an average, the systems are able to deliver over 2MW free heat energy for your residential water applications.

Northern Lights made solar heating kits are specifically pre-engineered and pre-designed for maximum performance and optimal level of safety. They take the guesswork from solar heating installations by providing pre-configured solar heating packages.

While designing a solar heating system, it’s necessary to make sure that you have the proper size. If you’ve an oversized system, it can actually minimize the overall performance and the payback in the long run. An oversized solar powered heating system tends to go into stagnation and switches off often than a right sized solar heating system.

It means, the solar system will stop working and offer zero contribution on solar during hot sunny days. A properly designed solar heating system is able to provide around 50-65% overall solar contribution.

Again the contribution will be more, if you’ll add a secondary heating load to the system like a hot tub, pool or home heating. When the primary system reaches its maximum capacity, the solar controller will set default to the secondary heating zone.

It will provide the solar heat energy to the zone by eliminating the probability that system gets overheated and goes into stagnation. There are so many factors necessary for designing a solar heating system. Here are some of the best reasons discussed below:

How Do You Design a Solar Water Heating System?

Location –

You should know the right location of your solar system as per the southern exposure. It can be ground, wall or roof. Generally, the location will help you know the maximum number of solar collectors – every collector requires around 8' 4" of width spacing and 6' 6" of vertical spacing. In addition, you can know the right angle as per the calculations discussed below:

For winter heating, the latitude of the location should be over 30 degrees. The latitude must be -30 degrees for heating during summer. The annual average heating depends on the latitude of the location.

Sizing of Solar Heating Package –

You have to choose the pre-configured solar heating systems (SWHs) as per the number of solar collectors for the application. Take a look at the discussed points to determine approximate number of solar collectors.

While considering the sizing of solar heating package, SWH-1 is ideal for 2-4 persons, SWH-2 for 4-6 persons and SWH-3 for 6-8 persons. Follow a rule a thumb, which states that a household with teenage kids will use more water than a house with only adults.

Make a decision on solar heating designs you need – a combo, indirect, or preheat solar layout for your residential heating applications.

Additional Heating Zones –

Consider using an additional secondary solar heating loop like solar home heating, pool heating or hot tub heating purposes. You have to increase the size of solar water heaters to accommodate to additional demands properly. For example, a 1200 square foot home for four persons with radiant floor heating requires a SWH-4, which is equaled to SWH-1 + 3 (400/1200). It will help you choose SWH-4 with in-floor heating design.

Bottom Line –

 

When thinking to invest in solar water heaters, you should look no further than Solar Tubs. We have solar heating designs like Supplemental Solar Water Heater with Internal Electric Hetaing Element for Back Up, Solar Water Heater with On-Demand Back Up Heater and Pre-Heat Solar Water Heating Design with Second Hot Water Tank.

How Do Solar Water Heaters Using Solar Vacuum Tubes Work?

There’s a huge availability of solar collectors on the market today. Flat plate collector is used most popularly in North America. It’s a good collector for residential hot water purposes. This collector works most of the season; but loses its performance during winter.

However, solar vacuum tubes are the most advanced solar collector technology available for solar water heating systems. They produce higher temperature. The main reason behind using solar evacuated tubes is that solar vacuum tubes deliver maximum performance in winter. It means, heating hot water during winter by using solar vacuum tubes will outperform all types of solar collectors available.

 

If you’re looking to produce solar hot water at a higher temperature, then you should consider heating with solar vacuum tubes. Rest assured that, you’ll get outstanding results. Solar evacuated tube collectors work like coffee thermos. Vacuum tubes absorb the heat energy that can’t escape easily.

But flat plate collector works like an ordinary coffee cup. The heat energy produced by a flat plate collector gets escaped through the walls of the collector easily. During winter, the outside temperature remains colder and the heat loss will be much greater with solar evacuated tube collectors.

This is the main reason why solar water heating systems using vacuum tubes are used in the Northern climates like Canada and Northern UDA. However, solar vacuum tubes are more popular in Europe and Asia because of the substantial low price.

It means, the overall cost of solar water heaters with vacuum tubes are much lower than their counterparts, which make them popular options to opt for. Nowadays two different heating systems are available within a 10% cost difference that means the vacuum tubes are growing rapidly in the US and Canada.

 

Another emerging market is home heating system using solar vacuum tubes. This heating kit delivers superior winter performance and higher operating temperatures. The home heating or space heating system becomes more popular in homes, shops, and commercial facilities.

 

A large size solar water heating system can be able to provide domestic hot water for home and additional heat to support the home heating system. It’s a right way to capture the full energy potential of the sun as the home heating and residential hot water account for around 80% of residential energy consumption.

When it comes to designing such system, you have to remember that the heat energy demand during summer is zero. Therefore, the additional solar heat requires to be controlled. You can divert the heat to a pool or a hot tub or you can get it done by covering the solar collectors with covers.

 

Solar Tubs – your ultimate solar solution supplier specializes in providing solar water heating systems using vacuum tubes. We have pre-packaged solar water heaters for both residential, commercial, pools and hot tubs.
