Timeguard Boostmaster Solar PV Boost Immersion Controller PV1000

This smart immersion controller intelligently redirects excess solar power to heat your water for free, helping you save money, reduce energy waste, and live more sustainably.

Eco-Friendly Innovation for Smarter Water Heating

Say goodbye to wasting excess solar energy. The Timeguard Boostmaster PV1000 is designed to harness every available watt your solar panels generate. Fitted with a single energy-sensing clamp at your household meter, this smart system wirelessly tracks how much energy you’re exporting. As soon as it detects more than 100W of surplus power, it automatically redirects that energy to your immersion heater.

Whether you’re soaking up the midday sun or catching afternoon rays, PV Boost continually adjusts to match the available solar export in real time. It only heats your water using surplus energy — so you never pay a penny more than you need to.

Why Choose the PV Boost?

If you already have solar panels installed, the Timeguard Boostmaster PV1000 gives you a smarter way to stretch every kilowatt. Instead of sending surplus power back to the grid, the system turns it into free hot water — reducing your reliance on gas or electric heating systems.

The result? Lower energy bills, reduced environmental impact, and hot water powered by the sun.
