SOLAR HEATING

Solar is a great fit with A2W heat pumps for both residential homes and large commercial systems.
Solar can reduce or eliminate energy usage and costs associated with operating a heat pump.
There are two types of solar that work with our A2W heat pumps: Solar Heating and Solar Electric.

We do not design/sell/install Solar PV, but can refer preferred contractors.

SOLAR HEATING

Sometimes referred to as the “other solar”, solar heating can reliably and efficiently be tied directly into an A2W heat pump system, or provide domestic hot water pre-heat on residential or commercial buildings.

Solar heating systems are not tied the electrical grid or subject to utility connections. They simply are a liquid-based, solar-powered heat source for hot water or space heating.

    1. Solar Heating Panels

    2. Thermal Storage Tank

    3. Circ pump and piping

    4. Solar Control

    • Solar panels collect heat

    • Solar control turns pump ON when solar panel warmer than tank bottom.

    • Pump moves heat transfer fluid through copper piping from panels to tank

    • Thermal storage tank or buffer tank stores heat

  • Solar Heating Costs

    Tie-in to A2W systems: $3k to >10k

    Residential hot water systems: $6k to $12k.

    Commercial hot water systems: $10k to >30k

  • To be fair, there were lot of systems installed in the late 90’s and early 2000’s that do not work and gave the technology a bad name.

    But, properly designed and installed these system last >30 years. Liquid Solar has installed over 200 systems.

Consider:

Gas & propane cannot be generated on your roof.

But heat & electricity from the sun can be.

SOLAR HEATING and A2W HEAT PUMPS

  • Since an A2W heat pump system already has a buffer tank with outdoor-rated glycol, adding solar heating does not require an additional tank; only the panels, some piping, and a solar control.

  • Solar heating panels add heat directly to the buffer tank so that the heat pump works less and uses less electricity.

  • Best suited to heating-only heat pump systems but can also do hot water pre-heating with the use of a specific tank we can supply.
