You have probably heard of solar panels producing electricity for the home, but do you know about solar panels which will heat your hot water? You can end your reliance on the suppliers by producing your own energy and avoid the ever-increasing National Grid rates.
Solar water heating systems take the sun’s heat and use it to warm water. Your immersion heater can then be used to increase the temperature further as needed. It’ll also come in handy when solar energy isn’t available.
How do solar thermal panels work?
When you invest in a solar water system, panels known as collectors will be installed on your home’s rooftop. They collect heat from the sun, which is then stored in a hot water cylinder. The boiler or immersion heater is still required as a back-up and to increase the temperature so it can be used domestically.
Solar panels are best fitted on a south or south facing roof, which will receive more of the sun’s rays throughout the day. However, even north facing roofs will still produce plenty of heat.
There are two types of solar water systems on the market:
- Evacuated tubes
- Flat plate collectors
It is possible to purchase larger solar systems which will provide energy for your central heating too. But despite this, experts claim they’re not worthwhile and will only offer a small contribution to your heating usage.
What are the benefits of solar water heating?
With solar thermal panels you can take advantage of a number of benefits including:
- Government grants: The Government has recently increased grants from £300 to £600, to help homeowners with the cost of installation.
- Reduce energy bills: You don’t need to pay for sunlight, so all the energy you produce with solar panels won’t cost a penny.
- A guaranteed income: With the Renewable Heat Incentive set to launch in spring 2014, you’ll be paid for each unit of energy produced.
