Benefits of Solar iBoost

With the Solar iBoost+ you can:

  • Cut the cost of water heating in your home.
  • Reduce the use of your boiler.
  • Maximise the use of the free solar energy generated.
  • Solar iBoost+ uses only the energy that would otherwise be exported.

Using just a single clamp installed at the household meter, the sender transmits vital export energy information to the Solar iBoost+ wirelessly.

Solar iBoost+ is activated when excess energy is available. It intelligently controls and adjusts the flow of energy to the immersion in proportion with the fluctuating export levels.

Water is heated during the day using excess energy only up to the immersion thermostat’s setting. You can top up if required from usual heating methods or using the Solar iBoost’s Timed Boost functions

Does the Solar iBoost+ affect my feed in tarriff payments?

The impact of utilising the Solar iBoost+ on your feed-in tariff (FiT) payments largely hinges on the specific regulations of the tariff scheme in your locale. Generally speaking, numerous tariffs are experiencing a reduction alongside the escalation in energy expenditures, thus promoting the “self-use” approach where individuals harness energy from personal photovoltaic (PV) or wind generation systems.

Under generation-based FiT systems, the payments you receive are typically not affected because the Solar iBoost+ primarily tracks the energy that is exported, not what is used on-site. For instance, in the UK, the extra export tariff is generally not metered, rendering self-consumption the more favourable option.

As for those on net metering setups, the advantage one might get is contingent on the specified tariff rate; however, consuming the electricity generated might prove to be the more economical choice compared to exporting it back to the grid. It is recommended to analyse your tariff’s terms to make the most financially sound decision.

Simple Design

The Solar iBoost+ offers a straightforward and tidy installation alongside your water cylinder, connecting effortlessly between a fused spur and the immersion without necessitating any alterations to your existing immersion heater of up to 3kW. It also includes an integrated programmable threshold, allowing for seamless integration with battery storage systems to prioritise its operation effectively.

Designed to adapt quickly to fluctuations in home consumption and weather changes, the system ensures that only surplus energy is utilised. Moreover, it supports connections for two immersions, toggling between them automatically to optimize your electric water heating setup. The inclusion of a Wireless Sender means you avoid both unsightly and expensive wiring solutions.
