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.

Out with the old, in with the new

Comments about TK-4-IN Takagi Tankless Indoor Water Heater (Natural Gas):
This has been used for years in Japan and no wonder it is the best. I wish I changed my old standing 50 gallon with pilot water heater. This is just the best! Plenty, plenty of hot water for two showers or more running non stop. Takes up very little space and turns on only when you need it. Install the thermostat that it comes with and you can control exactly what temperature you need for the hot water. It is just perfect. Cannot say anything bad. Here in the US they just sell the big water heaters at the big box stores and waste so much space and energy. What a great thing this is and it is made in Japan, yes Japan. I would give it the best rating. Very, very happy. Installation is easy, and can find samples online just hook the gas, water, install service valves to flush with vinegar once a year to get rid of lime and other deposits and install a pressure regulator on the hot water. Just the best!
Bottom Line Yes, I would recommend this to a friend

I'm very Happy with this product
from Springfield, MO
easy to install, and my family couldn't be more pleased with the amount of hot water it produces. I would highly recommend this to any person wanting to convert to a tankless system.

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.
