Thinking of adopting green technology in your home? Consider solar water heating systems for homes! This technology enables you to harness the power of the sun and use it to heat your water. Why is it becoming a popular choice amongst homeowners? Apart from its ability to heat water without increasing the carbon footprint, solar water heaters are efficient, guaranteed to reduce your monthly utility bill.
The following is a brief explanation about solar water heating systems for homes and how they operate:
What is a solar water heater?
This is a device that captures sunlight and heats the water in the pipes which can be used for domestic purposes, i.e. bathing, washing, etc.
It has four main components which work together to produce heated water. These are:
1) Thermal Panel or solar collector: This is installed on the roof. It gathers the sun’s rays on its flat surface.
2) Tank: This is where hot water is stored.
3) Circulating Pump: This accessory transports solar energy gathered from the collectors and transfers it to the tank.
4) Thermal Regulator: This device behaves much like a thermostat and regulates the heat of the system.
How do solar water heating systems for homes work?
The solar collectors on the roof absorb the sun’s light. The panels covert this into heat and pass it onto the water tank via a circulating pump. The thermal regulator triggers this exchange as soon as the temperature of the collector becomes hotter than the water within the tank. This inhibits the circulating pumps from using up too much energy. It also stops overheating.
What is the best way to fit collectors for maximum efficiency?
The collectors are most efficient during the midday in the summer months, pending the sky is cloudless and there is south-facing orientation. Collectors work fairly well in other seasons too, even when they’re facing east or west. For maximum efficiency, a 35 degree gradient towards the horizon is best.
In cases where there is insufficient sunlight, you may have to invest in a back-up system. This will bring the temperature of the water up without emitting carbon dioxide into the atmosphere.
Why opt for a solar water heating system?
With a solar water heater, you have an unlimited supply of sunlight to heat your water. It can provide substantial savings throughout the year. For example, a sun shining on a 1m² roof can replace 100 litres of heating oil and 100 m³ of natural gas. You can use solar energy for up to 70% of your domestic requirements such as running the dishwasher or washing machine, bathing, etc.
An investment in a solar water heating systems for homes will provide a lifetime of savings. To learn more about how this technology works, please contact PS Solar System.
