Released in 2010, the T-K4 improves upon many of the features from the T-K3.
The T-K4 is one of Takagi's smaller tankless water heaters. At 13.8 inches wide and weighing only 38 pounds, its ultra-compact design allows it to be mounted on a wall.
Takagi's newest tankless water heater also features an energy factor of 0.82, so it is extremely efficient and environmentally friendly. Since tankless water heaters only burn gas when hot water is needed, installing this unit can help homeowners save up to 45% on their monthly gas bills.

Endless hot water
By Steve B
from Midland park nj
Had it for 2 years never ran out of hot water... It's a great investment .
Works excellent, good product for the price

SHORT TERM GOOD RATING.
from KENT, OHIO
IT WAS EASY TO INSTALL BY MYSELF. HOWEVER THIS VOIDED THE WARRANTEE SINCE I AM NOT A LICENSED PLUMBER. LIKE THE REMOTE CONTROL PANEL. I INSTALLED IT NEXT TO THE FURNACE CONTROL. IT'S ONLY BEEN 3 WEEKS SINCE I INSTALLED IT BUT WE'RE VERY HAPPY WITH IT. THE PRICE THROUGH PEX SAVED US A LOT OF MONEY OVER THE CONTRACTORS PRICE. TAKAGI IS OWNED BY A.O. SMITH COMPANY SO THAT HELPED MY CONFIDENCE LEVEL ON DECIDING ON THIS PRODUCT.
from Jackson, MI
Works great, easy to install, and after running two showers, laundry and a dishwasher simultaneously to test it, everyone still had hot water.

Yes, this is the best
from Kennebunk, Maine
We use this product to make all our hot water for showers and baths plus everything else that you use hot water for. The unit is very easy to install and starts to work perfect . We never thought that it would work as good as it does and are very happy with it. Now we are staying in the shower for a long time and just enjoying the hot water. I just had a total shoulder replacement and the amount of hot water I let run over my shoulder is incredible and it just keep on going , this alone is worth it. It also is very inexpensive to operate.
First really hot bath in a long time
By Roger Q
from Roland, AR
We built out house 10 years ago and had a High Efficentcy Tank Water Heater which recently started leaking. We replaced it with the TK-4-IN Takagi Tankless Indoor Water Heater (Propane) and it's working great. We have a large soaking tub and we're now able to fill it easily with piping hot water.
Great price, works great, 40% gas saving
from Boerne, TX
Installation is very clean and straight forward. Comes with a good manual. We never run out of hot water - don't have to wait for the water to heat back up when she fills the garden tub to take a bath. I'm amazed at how much we're saving on our gas bill. I never dreamed the water heater was consuming so much gas.
