Tankless Water Heaters, also called On-Demand Water Heaters, instantly heat water as it flows through the heater, thus they do not retain any water internally beyond the heat exchanger. Most tankless water heaters utilize copper heat exchangers to heat the water, as they are easy to work with and they have an extremely high thermal conductivity.
Most early designs of tankless water heaters were of the point-of-use (POU) type, where the water heater is located near to where the water is being used. These early designs saved energy and reduced water loss over conventional hot water heaters, and are still commonly used today. In recent years, higher-capacity tankless water heaters have become more common. These are often installed in combination with a central water heater, to reduce the cost involved of purchasing and installing a POU heater for every area where hot water is needed. Hybrid water heaters, that combine the best features of tankless water heaters with conventional water heaters, have also become more common.
Benefits of Tankless Water Heating Systems
The primary advantages of the tankless water heater include:
- They provide a plentiful continuous flow of hot water – and are not limited as with conventional tank water heaters.
- They can provide significant energy and cost savings over the lifetime of the heater over conventional hot water heaters.
- They have a longer life expectancy than conventional heating systems.
- Tankless hot water heaters use less physical space than conventional models.
Tankless hot water heating systems do require a higher initial investment than a conventional hot water heating system, due to equipment and installation costs. But these costs are quickly deferred by the long-term cost-effective savings provided by the tankless system.
Installation Challenges of Tankless Water Heating Systems
Tankless hot water heaters can also posses some installation challenges. Finding the ideal location for POU heaters can be difficult if space limitations are present. As noted earlier, the costs related to installing a tankless hot water heating system is relatively high; in a recent study, the average installation costs topped $1500. The cost is due to the fact that more labor is involved in installing a tankless system than a conventional system.
That notwithstanding, there are some real, cost-saving long-term benefits of a tankless hot water heating system. At Plumbwell Services, we have installed tankless systems for countless customers who have appreciated the long-term and short-term benefits of the system.
