Description

Stiebel Eltron Tankless Water Heater – Tempra 24 Plus – Electric, On Demand Hot Water, Eco, White, 20.2 "The Stiebel Eltron Tempra 24 Plus Tankless Water Heater features exclusive Advanced Flow Control German patented technology invented by Stiebel Eltron to automatically maintain water temperature for constant comfort. It’ll reduce flow slightly if hot water demand exceeds capacity to ensure that hot showers will never be interrupted. Tempra 24 Plus will typically use 15-20% less energy compared to conventional electric tank water heaters. Although, it’s possible to save significantly more energy depending on personal home usage habits. The difference is that conventional tank water heaters continually store hot water, and as a result, lose 15%-20% of the total energy consumed to the environment around them. This is called standby heat loss. Tank water heaters that use gas or oil are even less efficient, because they also lose heat through their vents to the outdoors. Our tankless water heaters do not need venting, and will not store hot water, waiting for you to use it. They operate on-demand to provide continuous and endless hot water when you need it, and not waste energy when you don’t. CERTIFICATIONS INCLUDE - ANSI/UL Std. 499, CSA Std. C22.2 No. 88, ISO 9001, WQA tested & certified against NSF/ANSI 372 for lead free compliance.

SIEMENS Q250 50-Amp Double Pole Type QP Circuit Breaker, Black Siemens offers a wide array of thermal-magnetic circuit breakers that are the key element for overload and short-circuit protection of your home's electrical system. To provide additional protection Siemens offers circuit breakers to protect against severe electrical shock or electrocution, mitigate the risk of electrical fires and protect against damaging surges and Voltage spikes. Circuit breakers are intended for switching and protection of your home's wiring from high temperatures caused by excess current higher than the rating of the wire. While thermal-magnetic circuit breakers are the key element for overload and short-circuit protection of your electrical system, there are potentially dangerous conditions that do not involve over current. To ensure the warranty on a Siemens panel is not voided, the use of Siemens breakers is required. Siemens strongly recommends against the use of "used" breakers. The installation of used breakers in a Siemens panel will void the warranty on the panel. Siemens does not sell used breakers and has not approved any 3rd party sellers to do so. Siemens plug in circuit breakers are intended for use in Siemens EQ, Siemens Ultimate, ITE, and Gould load centers or meter combinations. The double pole Siemens breakers may be used in 1 or 3-phase load centers and are 240V rated. To ensure the warranty on a Siemens panel is not voided, the use of Siemens breakers is required.

  • Really nice!
Style: Tempra 29 Plus (29 kW) Pattern Name: Water Heater + Circuit Breaker
Once installed runs really nice - silent, runs two full showers with no issues - Be sure to get a qualified estimate for your power installation as it can be very expensive!

  • Works well so far
Style: Tempra 29 Plus (29 kW) Pattern Name: Water Heater + Circuit Breaker
Our traditional tank water heater blew out and we took the opportunity to go tankless. We have had a couple unfortunate plumbing events this winter, so we do not have a good read on our water/energy efficiency yet. Out biggest concern was whether we would be able to convert easily from a natural gas tanked heater to the electric tankless. We did the plumbing and electric ourselves. The instructions are not the clearest on the electrical set up, so we turned to YouTube to find someone that did it already. We were only able to find a video (Part 1) that showed the water connections, which were pretty straight forward anyways. We could not find Part 2 on the electric, so we proceeded with fingers crossed. In the end, we were able to make the connect without incident. It would be helpful if the company offered step-by-step video instructions. ... show more

  • Works great
Style: Tempra 29 Plus (29 kW) Pattern Name: Water Heater + Circuit Breaker
We've been using our tankless for our family of 5 for over 6mo. The husband and I installed this ourselves in no time. Works great, we never run out of hot water. We lose a little pressure if the dishwasher or washing machine is on, but that's to be expected. Worth every penny.
