Marlec Solar iBoost+

Marlec’s innovative Solar iBoost+ diverts the surplus solar photovoltaic energy generated at your home to heat the water in the household tank and save you money.

Fitting the iBoost means 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 at your property.

Solar iBoost+ uses only the energy that would otherwise be exported. Its increased efficiency and extra functions deliver even more savings and when coupled with iBoost Buddy you can conveniently monitor and control Solar iBoost + within the home.

With over 45,000 Solar iBoost products successfully working in UK homes installers recommend it!

Key Features
- Solar iBoost+ fits quickly and neatly next to your water cylinder wired simply between a fused spur and the immersion. No need to change your standard immersion heater up to 3kW.
- It responds rapidly to the varying home consumption and changing weather ensuring that only excess power is used.
- Solar iBoost+ features connections for 2 immersions, switching between them automatically to maximise electric water heating systems.
- Wireless Sender eliminates unsightly and costly wiring.
- Solar iBoost+ displays real time information “Heating by Solar 1.6kW” and historical energy saving figures are seen at the push of a button. View this and more data using the optional iBoost+Buddy home display.
- LED’s also give an instant visual indication of the system in operation.
- Simple programmable timer enables Solar iBoost+ to work in harmony with your existing water heating system on a 5/2 day basis. Even separate winter and summer settings can be programmed and switched between at the push of a button.
- Selectable languages; French, German, Italian, Portuguese & Spanish.
- Built-in Boost override switch keeps you in control so you can top up your hot water in 15 minute increments up to 2 hours.
- Solar iBoost+ is ready to connect wirelessly to the Buddy if added at installation or a later date.
- CE compliance to all product and safety standards conducted by independent test laboratories.
- 2 year warranty. Dimensions: 288x255x100mm 1.95kg

How does it affect your Feed in Tariff Payments?
It doesn’t! In the UK FIT generation payments are not affected. As most export tariff contracts are based on deemed energy usage rather than actually metered self consumption is most beneficial. Solar iBoost+ enables you to usefully and automatically consume any excess energy generated rather than export it. Even with an export meter the benefits of Solar iBoost+ can still easily outweigh rising energy costs.

Please Note: This product should be installed by a qualified electrician.

Unexpected boost to our Solar thermal

Had solar thermal installed 15 years ago then 9 years ago had solar PV. But decided not to install an i boost as we were already getting hot water even in winter it would raise the tank temperature 10 degrees. However we would only get a full 60 plus tank for about a month or 2. Then after getting a smart meter fitted in February we realised how much our 2.5kW system was exporting so brought the i boost. This has transformed the solar thermal which now heats quicker and even in March we have had several 60 degree full tanks. Conclusion I am kicking myself that we didn't do it earlier.
