Baxi Solarflo Evacuated Tube Collectors

How does Baxi Solarflo use the power of the sun?

Baxi Solarflo uses the free power of the sun to heat solar collectors on the roof and turns this renewable energy into thermal heat to create hot water for the home.

It's simple, effective and entirely renewable which is good for the environment - and good for future generations.

The Baxi Solarflo consists of three main elements:

• Solar collector
• Hydraulic pump station and controller
• Solar cylinder (available separately).

How does it work?

The solar collectors are mounted on the roof and absorb the heat from the sun's rays, transferring the heat to a fluid.

The fluid is circulated from the panels through to a special solar coil in the base of the hot water cylinder.

The heat is transferred to the stored water and then returns to the collectors to be re-heated and continue the process.

How much hot water does the Baxi Solarflo generate?

During the summer months, it can generate as much as 100% of the domestic hot water required for an average household.

In the winter, as much as 30% can be generated, with the remainder being provided either by a conventional boiler or electric immersion heater.

On average, it will generate around 50-60% of the annual domestic hot water requirement.**

How many evacuated tube/panel collectors will I need?

The amount of solar collector area needed relates to the size of the solar cylinder.

The size of cylinder required is dependent on:

• the number of people in the household
• the amount of hot water required daily for baths, showers etc.
• number of collectors may also depend on available roof space.

Typically, a home with a family of four will need two solar collector panels or a thirty evacuated tube collector.
