Typical day running BOLT

A typical BOLT day for a 16kw boiler with one battery starts with a fully charged battery, charged over night with the low tarriff energy rate.

BOLT turns on arouund 6am to warm your house up and has enough energy stored for 2, 15 minute high flow showers at 11 l/m. Once the battery is empty, BOLT can still provide normal showers at 8l/m.

During the day, the battery will charge up to full using solar in about 1.5 hours, (even in winter) meaning you have a charged system for the evening showers.

Bolt heating will come on to warm your house for the evening.

Once eveing showers have finished, BOLT will wait for the low tarriff time to charge up your batteries again.

The batteries can be stacked to provide you with more shower time if needed.
