OPTION 3: Heat Pump backup Integration
This option incorporates a backup thermostat plus a hot water/hydronic heat pump to top up the water temperatures as a backup. This is especially beneficial in the early years as the heat core heats up, but is equally significant as it it also backs up the domestic Hot Water with low cost heat.
The DSHH controller allows you multiple turn on times to ensure your hot water is available regardless of the schedule you are on.
OPTION 4: Spa or Pool heat
Increase the solar collection to heat or pre-heat a spa or pool. A large 1,000L storage tank is often required. Be sure to ask for details.
