Northern Lights Solar Hydronic Heating Systems use a special solar storage tank that have a larger 119 gallons of storage capacity capable of holding over 120,000 BTU (35 Kw) of heat energy at any time. These tanks have a dual heat exchanger. The bottom HX transfers the solar energy to the tank and the top exchanger removes the energy form the tank to move it to the hydronic zones in the house.
This storage tank system allows for solar storage during the day and can release the stored energy at night when the demand is usually higher. The storage tank can also be used as a domestic hot water tank so that the solar can provide both solar water heating for domestic hot water and space heating in one system.
Our Solar Hydronic System comes with a 4.5 Kw element located in the middle of the tank. It is optional whether a customer uses this or not. The element can be used to ensure there is always hot water even in the evenings. This Hybrid system is especially popular for Solar Radiant Floor Heat, because the solar space heating system can replace the need for a Hydronic boiler as the 4.5 Kw heater and the solar energy should provide enough energy or up to about 2,000 square feet of solar heating space. The Resol controller is capable of controlling both the solar heating loop plus the 2nd heating loop. This type of integrated solar heating package has the highest solar heating paybacks!
Solar Home Heating combined with Geothermal heating is another very popular means of combining two green energy sources to provide a Maximum Cost Savings. By using any excess heat from the solar water heater, we can add this energy to the geothermal loop by means of a heat exchanger. Click here for more information on solar heating & geothermal.
