Solar space heating systems are one of the most well-known solar thermal systems in the industry. They use solar evacuated tubes which perform well in low light conditions and temperatures that reach minus 35 degree.
You can integrate solar thermal with an existing heating system like radiator, in floor heat or forced air heat. As a homeowner, you can expect to save up to 50% of your heating bill. After all home heating consumes a great portion of your energy utility bills – the payback can be under 5 years.
The Basic Principles of Solar Space Heating Systems
The solar space heaters use the solar evacuated tube collectors to absorb solar energy. This energy is again transferred to a storage tank or concrete pad (in floor heating). The heat that stored is then integrated with the existing heating systems to provide the heat supply.
The solar space heating kits provided by Northern Lights come with larger 119 gallon storage tanks that can hold more energy and can be used in the evening to supply heat when the sun isn’t shining. The demand for heat happens during the winter; though a secondary dissipation loop may be required to off load the heat during the summer months.
If you use a pool or a hot tub at home, the excess heat energy can be transferred in the summer offering the customer enough heat in the winter. Alternatively, a dissipation loop like buried pipe or exterior fan can be utilized to dump the heat. A geothermal system is also perfect way to get rid of the excess amount of heat in the summer storing it in the ground for the winter.
The sola space heating systems are used in colder regions as they are susceptible to freezing. A special solar glycol heating fluid is utilized to avoid the damage that would be caused due to frozen pipes. This special fluid can work at -40F, but can operate at temperatures as high as 480F.
The Northern Lights solar space heaters use specially designed solar storage tanks with a larger 119 gallons of storage capacity – which can hold over 120,000 BTU (35KW) of heat energy at any point of time.
However, the solar home space heating system combined with geothermal heating is a very popular way of using green energy sources to provide maximum cost savings. Using any excessive amount of heat from the solar water heater, Northern Light adds this energy to the geothermal loop through a heat exchanger.
Another way of heating with solar is through solar air heating systems. This is a much more affordable way of space heating; but it lacks the capability to store heat energy. The air is heated through a layer of glass and selective coated material for the heat absorption.
A solar PV fan system scatters the heat throughout the house as per the thermostatic controller. It’s also ideal for homes with crawl spaces or basements that need to heat the colder air.
Final consideration –
It’s time to invest in solar space heating systems and take advantage of savings on utility bills effortlessly. Do a thorough research and make a right selection for your residential applications.
