Why Do You Buy Residential Solar Water Tanks?

Introducing a Solar Water Tank –

 

A solar water tank is an important part of your solar water heating system. When it comes to buying solar water tanks for home, the type and size are the most important things to consider. Latitude51 Solar uses the SolarStor solar water tanks, manufactured in the USA. Their solar storage tank is the UL certified water tank and comes with top and bottom internal heat exchanger and middle 4.5 KW backup heating element. 

When you buy solar water tanks, you can have both pre-heat solar tank and supplemental solar water tank. The supplemental tank allows you use a tank and during shortage of solar energy, the electric element supplements the solar energy. This means, when investing in solar hot water, you no longer need to buy two tanks, making much better payback. 

Why Do You Buy Residential Solar Water Tanks? 

Solar water tanks are used in residential applications and are completely different from ordinary hot water tanks. They are the very important part of a perfectly designed residential solar water heater. The main objective of a residential solar water tank is to deliver thermal storage for the solar energy; which works similar to a battery in a solar PV system. 

Earlier, most DIY users converted a regular tank to a storage tank by making the use of T&P valve port and drain ports as opening and operating an external heat exchanger on the tank. It was primitive type of water tank and resulted lot of issues like thermos-ports for temperature measurements. 

Internal Heat Exchanger 

A residential solar water tank comes with built-in internal heat exchanger to deliver the best possible heat exchange as possible as it’s inside the potable. In fact, the solar storage tank insulation is better than the most standard water tanks as the tank may require energy storage when it’s not sunny. 

Another important feature of solar water tank is the direct thermos ports inside it. This allows solar controller to measure the water temperature accurately inside the system. The Solar Stor tanks available at Latitude51 Solar come with both a top and bottom thermo-port for two sensors. 

Understanding Single Coil & Double Coil 

If you want to have solar hot water at home, all you need to have is the single bottom heat exchanger coil in your residential tank. If you have a plan to add a second heating zone in the future, you should consider planning on a top and bottom heat exchanger. 

However, the top heat exchanger works opposite of the bottom and eliminates heat from the hot water. It delivers to the second heating zone as required including a pool, hot tub, hydronic floor heat or an air handler in the forced air furnace. 

Knowing the right size of residential solar water tanks 

All the UL and CSA certified storage tanks have a maximum capacity of 120 gallons for residential applications. Generally, it is large enough for a family of 8 people. You can add it to three collector solar heating system.

Again if you want more storage, you can consider combining multiple storage tanks to form a larger bank of batteries, add them in parallel way. It will give you an affordable way to double the storage ability for applications seeking for enough heat energy like space heating.
