great value
$135 including tax is great value for small house lightweight makes installation easy can run 1 shower and sink simultaneously but pressure drops should have a 110v plug in instead of 2 D cells. We are worried the batteries won't last no marking for which way batteries should be installed. instructions were horrible one of the pipes was loose when we tightened the connection. It did not leak luckily shipping took 6 days instead of the promised 1 day$135 including tax is great value for small house lightweight makes installation easy can run 1 shower and sink simultaneously but pressure drops should have a 110v plug in instead of 2 D cells.

A tankless water heater
I have hooked the water to this heater I have hooked gas to this heater I put batteries in the heater and I cannot get this heater to light up I cannot get this thing to light the low voltage lights the battery powered lights the neon that's where it shows the temperature I'm not sure why and I need to know what else I can do to get this thing to work otherwise I've got to send it back I just need advice on a problem that could be stopping me from putting this thing into use. My review right now is a bit negative as I can not get this unit to light up. I'm sure my opinion will change once I get it the unit workingI have hooked the water to this heater I have hooked gas to this heater I put batteries in the heater and I cannot get this heater to light up I cannot get this thing to light the low voltage lights the battery powered lights the neon that's where it shows the temperature I'm not sure why and I need to know what else I can do to get this thing to work otherwise I've got to send it back I just need advice on a problem that could be stopping me from putting this thing into use.

So far so good
Using this to heat my Intex pool. Wish the directions were a little more descriptive. Marking the battery polarity would also help. There is also a switch that is not mentioned. Just little stuff that could make it better. There is a summer/winter switch too without any explanation. Ill will see where we are at after a few months of operating the unit. I will say it heats the water nicely.

Instant Gas water heater Tankless Home Install DIY
Instant Gas water heater Tankless. It must be said the water and gas connections are all 1/2 inch. Your regular home water source is 3/4 inch. You'll need an adapter. You'll need a 1/2 in gas nipple that fits your flexible gas hose. The water inlet and outlet on the water heater are too close together. I created an extension with 1/2 in copper with female and the other end, male, approx 5 inches (best 8 -9 inches) This allow me more room to fasten all the connections. Connect the gas last with yellow tape. Put plenty of white teflon tape on all the water connections. Watch the cold water connections because you can just unsrew it right out of the heater. Note: I said all that because you should put the double valve shutoff setup so that you can do some maintenance on the ... Instant Gas water heater Tankless.

Note: I said all that because you should put the double valve shutoff setup so that you can do some maintenance on the heater. You can close off the inlet and outlet while running a cleaning liquid through the system and out. Then put the batteries. Look at it carefully and you'll see one of the slots has the spring, which means negative. 2 D size batteries. Close the white door and twist to lock. Turn on the switch. You can't see anything until the hot water faucet is turned on and water goes through the heater. The hot water is not instant but it will get pretty hot. Adjust after you use it a few times: dishes, showers... Started using 1 week ago. Works well. Gas is a little loud. Buy water heater exhaust adapter to the original exhaust to the roof and good inlet air under the house?
