Buying advice for solar water heating
Solar hot water heating panel
Solar water heating systems qualify for the Renewable Heat Incentive
Read on to find out what you need to know about buying solar water heating panels. We’ll show you the sales tactics you need to watch out for, plus how to get a reputable installer.
Choosing a solar water heating system
When choosing a solar water heating system, you’ll need to consider four major factors:
your average hot water use
the area of south-facing roof available
your existing water heating system
your budget.
You’ll need roughly one square metre of collector area per person in the household. Each metre of panel area will need between 30 and 60 litres of water-tank volume.
If you use a less efficient collector (such as flat-plate solar water heating panels), you’ll need to cover a larger area than if you use a more efficient collector (such as evacuated tubes).
You’ll also need to select system components (such as a hot water cylinder, controls and pipe work) and choose the location for your solar panels, considering shade, pipe runs, roof pitch and future access.
