Our engineering excellence and high-quality manufacturing results in products fulfilling the highest expectations of performance & reliability. Tempra Series whole house tankless electric water heaters are 99% efficient and never waste energy storing hot water, but endlessly deliver it as needed. Tempras need no venting. Installation can be close to draw off points, making the wait for hot water as short as possible & maximizing energy savings. Tempras are sized based on the number of bathrooms.

Rated 5 out of 5 by from So far so good We replaced two electric water heater tanks with this one on demand unit. Been a very cold winter so far here in Halifax and no issues with it supplying hot water. Haven’t seen a power bill yet to compare but hopeful for some savings. Love the peace of mind of no water tank to fail and leak and the gained room by eliminating the tanks. Gives us two extra storage spaces. Very easy to install. Plumbed it so it can easily be flushed with vinegar to remove any scale buildup that may develop.

Rated 4 out of 5 by from Works as advertised Have been using this model for over a month now and it works fine. Just be careful about the minimum flow required for the unit to start heating the water. This is s very important specification. If you just want warm water (mix of cold and hot) on one faucet, this unit will likely not give you that with todays faucets which restrict the flow. You'll only get cold water. For me this unit is fine but I would have been better off with a smaller model that has a lower minimum flow. I assume this would be the case for most household.

Rated 5 out of 5 by from Tempra Plus 28.8 kw Great product would recommend for showers lots of water flow. To fill bath a little slow but still great.

How many gpm does this heat?

Asked by: Bsplicer
The final GPM output depends on the incoming water temperature. In colder climates, this unit would range about 3 - 4 GPM, in warmer climates this unit would range around 5 - 6 GPM Please feel free to contact our Technical Department at 1-800-582-8423 ext 6 with any further questions. Thank You.

What is the minimum flow rate required for the heater to kick in? Also what is the peak GPM that I can expect with a 5 degree Celsius cold water source?

Asked by: Mike
The Tempra 29 Plus requires a flow rate of .77 GPM to activate the unit. We try to suggest setting these units so you have a final output of about 110 degrees F (44 degrees C). With a 41 degree F inlet temperature (5 C) you should get about 3 GPM (Gallons Per Minute) from this heater. Please feel free to call our Technical Support Department at 1-800-582-8423 ext 6 with any questions. Thank You.

I live in Milton, Ontario approximately 3000 sqft, 4 bath home running on well water, does anyone have this unit or similar one and how does it work any complaints, any energy savings?

Asked by: Dan2097
This would be the unit most commonly suggested for a home like this. We would also suggest having your well water tested for minerals to ensure the correct filter is installed if any are found in the water quality report.
