pv energy payback time
Tankless hot water heaters, while more efficient and cheaper to use than the traditional water heaters, may not be as cost effective in saving you money on your electricity bill as you first thought. Especially if you have a family who likes to indulge in their never ending supply of on demand hot water. The other thing to bare in mind is that the tankless hot water heater has to heat the water up from cold each time your household request hot water. This not only wastes water as the cold water has to be kept running until it runs hot, but uses energy to heat the water. In the winter months, it will use much more energy.
So, it is not strictly true that you will save money when you switch to a tankless hot water heater – it will depend upon your family using it considerately and the time of year for you to make real savings on your electricity bill. There is a way however to make your tankless water heater an electricity saver. Combine it with a solar energy system and install solar panels. Under taken as a DIY project, you can easily install your own solar panels for as little as $200.
Solar energy can save you a staggering 70% on you electricity bill. It’s clean and free and any excess you produce can be sold back to your electricity company. And by law, they are legally obliged to buy it from you. A tankless hot water system is a very efficient way to provide hot water for your home. But by coupling it with solar energy, you can make it and exceptionally energy efficient and cost effective domestic utility as well.
