Many people have discovered the advantage of using a tankless hot water system to use as part of their radiant heating system. Previously, the established method was to use a boiler system but this has gotten more expensive as time goes on due to the fact that often as much heat is lost as it is produced.
A tankless system helps maintain the right temperature and only uses the amount of energy necessary to maintain the heat in the system. It is even more efficient than using a hot water heater system as multiple tankless systems can be used and each only uses the correct amount of energy for the job.
It’s All About Energy
When discussing heating systems, even hot water systems, it is all about the energy. In simple terms, the more energy put into the system, the more heat is produced. However, it is never that simple as often heat is lost as well, so the system is not operating at its maximum efficiency. So, the more energy put in also means more heat is lost requiring more energy to be put in etc. Tankless systems only put in the amount of energy necessary to maintain the heat that is already in the system, once it has been brought up to the correct temperature.
For radiant heating systems, this means that there is a direct correlation to how much heat is produced by the system. This is far more efficient than using a boiler or hot water heater. In those systems, heat is also lost at the source, in the tank or the top of the boiler itself. This is wasted heat. In a tankless system, the energy is directly applied to the water thus reducing the amount of heat lost at the source. In addition, you can have more than one tankless system for your home so you don’t have to maintain energy supply to keep your hot water ready, saving you, even more, money and energy.
