Benefits of solar water heating

sawoerHeating up water is one of the major uses of energy in the home – accounting for between 30% and 40% of the daily load. And because hot water is used for so many of those daily activities like showering, washing dishes and doing the laundry, it’s a daily load that almost doesn’t vary throughout the year. On average, a family can expect to use about 150 litres of hot water per day. Depending on the time of year and the type of water heater used, that’s equivalent to a daily demand of around 10 kWh for an electric hot water system and 30 MJ for a gas system. From the perspective of greenhouse gases generated, the two system types might be contributing between 1.5 and 3.5 tonnes per year of CO2 equivalent. A solar hot water system can save up to 80% of the electricity or gas usage – with similar savings on greenhouse gas emissions.Whether it’s for economic or environmental benefits, or a combination of both, it makes sense to choose a solar hot water system.
