The Baxi SolarfloTM solar thermal heating system uses the sun's natural power to provide energy efficient hot water for the home. Switching to a renewable energy source like solar heating can result in significant savings, both in CO2 and energy bills. The technology is simple, effective and entirely sustainable which is good for the environment - now and in the future.
Flat plate on-roof collector panels are mounted on top of roof tiles or slates and are therefore most suited to providing solar heating to existing properties, whereas in-roof collector panels are perfect for integrating solar heating into new-build properties as they are built into the roof structure. Evacuated tube collectors offer premium solar heating performance even in cloudy conditions and complete flexibility as they can be mounted on any surface, including façades and flat roofs.
How solar thermal heating works
A solar thermal heating system such as the Baxi SolarfloTM consists of three main elements:
- Solar panels or collectors
- Hydraulic pump station and controller
- Solar cylinder
The solar heating panels or collectors are mounted on/in the roof where they absorb the heat from the sun's rays. This is transferred to a fluid, which is circulated through to a solar coil in the base of a specially designed hot water storage cylinder, such as the Heatrae Sadia Megaflo Solar. The heat is transferred to the stored domestic hot water. The cooled fluid is then returned to the panels or collectors to be re-heated, starting the whole process all over again.
Effectiveness of solar heating
During the summer months, a solar heating system can generate as much as 90%* of the hot water required for an average household; even on dull days some hot water can be produced. In the winter, up to 30% can be generated, with the remainder being provided either by a conventional boiler or electric immersion heater. On average, a well-designed solar heating system will generate around 55% of the annual domestic hot water demand while also substantially reducing carbon emissions.
Solar heating accessories
In addition to the standard components included with the Baxi SolarfloTM package, there are a number of optional accessories available to enable more flexible installation. The range includes an on-roof East/West Array Kit and an in-roof East/West Tile Kit, which enables solar heating to be installed even if the roof is not south facing.
