One of our readers recently wrote in asking for hints on finding solar water heater manufacturers in California, mainly to avoid the high cost of shipping from overseas. Luckily, finding solar companies in California keeps getting easier, manufacturers included.

There are innumerable sources of information across the Internet, all with their own twist and turn, and it can be difficult to find a concise list from any single source. But they do exist. The best list I found was from the Utility Consumer’s Action Network (UCAN). Their list does not separate water heater manufacturers by state, but instead by SRCC certification — a must for reaping federal solar tax credits. So some browsing will have to be done, although it takes little time to find quite a few solar manufacturers in California. Here are a select few:

Heating, ventilating, and air conditioning – HVAC — is a critical component of any modern structure, from a single-story ranch house to the tallest skyscraper. Typically, any power that an HVAC system needs to function is drawn directly from the electric grid, the same as other home systems. Only in recent years renewable energy has raised questions about the very need for outside power in the home.

Solar power has been a big part of a change that is sweeping the world, as millions of homes and businesses turn to alternative resources to supply at least a hefty percentage of their power needs. Solar is most famous for creating electricity and heating water. Yet its footprint in the HVAC sector is bigger than you might think.

Passive Solar

While the effect may be subtle, it is impossible to ignore the influence that passive solar design has on a structure’s HVAC system. A smart home design will harness the sun for heat during cold months and minimize that heat gain during the summer, both of which lessen the workload for the HVAC unit. Passive solar air heaters can also be used to heat rooms and fit right into a window or wall.

Heating

Most HVAC systems are active electric or gas systems, but there are active solar space heating systems out there as well which supplement or even eradicate the need for outside sources of power. Solar heating systems are solar thermal systems by nature and themselves may be active or passive and liquid or air-based. The high initial cost of solar heaters is really the only barrier to more widespread use. Given time, every system will eventually save money by reducing or erasing high and rising monthly power bills. (more…)

Q: Can I use solar hot water in my kitchen?

A: Absolutely. The vast majority of solar hot water systems are “wired” right into your home’s existing water system, heating water for use from any faucet in the home, including the kitchen. Most systems connect directly to the current hot water tank, turning the conventional gas or electric water heater into a backup system.

I suppose you could install a solar hot water heater specifically for kitchen use, but unless you have an unusually large kitchen, this would unnecessarily limit the system’s potential. For most residential systems, an average sized solar hot water system can handle as much as 80% of the family’s hot water needs. You need do nothing more than connect it to the existing tank and enjoy clean, free hot water. (more…)
