Tankless Water Heaters - Point of Use Vs Whole House

Oklahoma city tankless water heaters are up to 50% more efficient than the traditional tank type heaters. As a result, you are not just saving money but also saving the environment as well. There are two versions of tankless water heaters, the point of use and the whole house. Point-of-use is a smaller unit, used for single or two outlets such as kitchen faucet and the shower. On the other hand, the whole house unit can accommodate simultaneous use of multiple hot water outlets which is ideal for bigger households. Let us have an example of each type of these heaters from Bosch, one of the leading manufacturers of tankless water heaters.
