Best Tankless Water Heater

best tankless water heater Tankless Water Heater saves energy by not having a storage tank full of water that is heated 24/7. Water is heated only on demand and at much higher efficiency. See here how Tankless Water Heaters Work.


Tankless Water Heater is Best Value delivering endless hot water. Correct Tankless Water Heater size calculation is important to achieve best Performace and Value. Who makes the best tankless water heater?


Tankless Water Heaters are nothing new, they have been around for decades, mainly in Asia and Europe. Gas water heater is generally the most economical hot water heater and tankless heater is even more. With tax credits and rebate they are even more attractive. The cost of tankless water heater depends on brand, size and installation location, see here for an estimate.


Why not get my Tankless Water Heater from Home Depot, Costco or other Warehouses?



We think service is a local issue. The Home Depot and large warehouses, including Costco, are offering Tankless Water Heaters and installation through large out-of-State companies, who often subcontract the work. It is like hiring an out-of-state plumber to fix the plumbing, in times when service is needed it may be difficult to get it. They are primarly in the business of selling, and not service.


Our price checks have also shown that there are no savings with their one brand choice and hence, are not able to provide the tankless brand and model best suited for your needs. All tankless brands are not equal, some are better in some installation and usage than other.


We carry all major brands of Tankless water heaters and are certified by major manufacture. We carry the all new condensing Rinnai RU98i, RU98e in addition to the new Rinnai Hybrid model RH180 that combines the advantages of a tank and a tankless water heater with high efficiency, contact us to find out of would meet your needs.


We recommend local plumbing companies who are experienced and are at hand when you need service. Having to wait on service for hot water can be very frustrating. Using local plumbers also helps your community by supporting local businesses.


And the liberal return policies of these warehouses hardly applies to an installed tankless unit.

the short answer is YES. They save Energy, Space and are environmentally friendly. Up to 50% Less Energy usage and CO Emissions for a little more initial cost than the traditional Storage Tank Water Heater.
