Tax Credit for Tankless Water Heaters


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 not something 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.


Fluctuating Water Temperatue at the Shower?


when experiencing fluctuatuating water temperature in your shower it is often not the fault of the tankless heater rather with the shower fixture. Many of the German brand Grohe and Hansgrohe fixtures are the cause of the problem. They have a built in thermostatic valve that tries to control the water temperature at the fixture and limit the max temperature. It then tends to oscilate between luke warm and hot as its thermostatic valve opens and closes. There is an internal adjustment to raise the temperature setting but these fixtures are over engineered and trouble some beside being expensive.


They may work well in Germany as many towns have central water heating. Yes, central water heating! You get hot water delivered just like cold water, a lot of times the hot water is boiling hot. There are two water meters, one for hot and one for cold. The hot water is being generated by garbage incenarators, cooling water from nuclear power plants, etc. and pumped throughout the town. Each home or building has a heat exchanger to extract the heat.


Why not buy a Tankless Water Heater from Amazon, Ebay, Home Depot or other Warehouses?


We think service is a local issue, not something that can be bought through the internet. Amazon and others have started on selling sevice online, for the referral they demand about 20% of the total cost. That is pretty steep and something the local plumber has to make up for it in other ways with the customer and not always in a transparent manner.


Should something go wrong the customer is caught between the seller (i.e.Amazon) and the installer (plumber), each pointing to the other for being responsible.


Similairly this is the case buying from Home Depot, Lowe's or other large stores. They subcontract the installation through a referral with steep referral fees from the installation company.


Some retailers even use out-of-state companies to install and when times comes for service they are not responsive.


Our price checks have shown that there is no price advantage compared to the local company selling and installing the tankless unit. Big box and online referred installation companies tend to be more expensive because of the installation company having to make up for the large referral fees.


Additionally Tankles Water Heater Manufactures require an installation by a certified installtion company in order for the tankless water heater to be warrantied.


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.
