Kat's 13150 1500 Watt Aluminum Circulating Tank Heater

The media could not be loaded.  Had this installed on my 5.9 CR cummins diesel and if I leave it plugged in for kore than 3 hours my engine temp is always over 115 degrees F. After startup it drops down about 5 degrees but I have warm air blowing from my vents instantly. I installed it inside my driver frame rail vertically, piped the bottom inlet port to the T fitting I purchased separately to my lower radiator hose. Piped the vertical outlet port to a plug on the driver side of the engine block. This thing is amazing and beats the tar out of the factory block heater.

Works great.I used this setup a little bit differently by plumbing it into my cars coolant circuit inline with the electrical auxiliary coolant pump.I used some relays and when i plug this in, i also power up the pump and a battery charger.Bought a 40amp ssr here and used a temperature controller.The nice thing about using this with a circulation pump is that it will not even get hot so the heater element should last much longer.In the cold winter months it would take about 2hrs to get the car to about 90-100F engine temperature. (2004 merc ml350)I used a wifi outlet that I can schedule when to start and i set it for 4am.That way every day the car was ready and warm. It starts and runs so much better.

I have the red 1000w Kats heater in one of my tractors, a JD 3130; it works great. But these aluminum Kats heaters are absolute crap, or at least the 1500 watt ones are. One hour ago, I installed the aluminum 1500W version in a JD 4020, and it's not even getting hot! Installation is straightforward; one end, with an upward arrow, attaches to a water hose that enters the block high and to the rear, while the lower end with a 90 degree fitting attaches low on the block toward the front. The radiator system on the tractor is brand new and clean as a whistle; I make sure the thing is full of coolant, tighten the hose clamps, and plug it in. NOTHING. Nothing gets hot, nothing flows. I check the breaker; everything's good. This has happened to me with at least three of these pieces of crap, and I'm sick of it. Who the hell is running the factory, a monkey? Where's the QC? If I wanted junk, I could get it for free, as opposed to paying $60 for it.

I installed this on a 1995 GMC pick-up. A previously garage kept vehicle that got kicked to the driveway for a new car and not previously subjected to cold starts. With a couple days of grinding cold starts (20-30 degrees), I looked for a heating solution. This was exactly what I was looking for! As mentioned in some of the other comments, I connected the unit to a timer that kicks on a couple hours before I leave in the morning. The instant heat is great, but the quick and effortless starting is even better. The entire engine block is warm to the touch, and you would think it had been running for about 15-minutes.I installed the unit using the block drain plug option. Since it requires gravity feed to supply the heater, I found a perfect location on the frame directly under the starter, and I used an existing bolt (13mm) that holds a brake line and some wiring. The supply hose runs from the driver's side, under the oil pan and into the heater. The product calls for 5/8" hose, but if you have to splice into 3/4" hose (like I did), don't buy reducers; just push the hose beyond the first bevel, and the clamps will hold. Total installation was about two hours, and you will need approximately five feet of 5/8" hose.The longivity of this unit remains to be seen, but it is currently exceeding expectations.

The quality of the product seems good, but I have yet to install this device as it's missing an adapter. The instructions suggestion to tap into the Lower Radiator hose, yet they don't provide you with the necessary adapter to make that connection. Given the cost of this, I would expect the parts list to be complete. Unfortunately, the instructions provided don't provide an inventory, so this isn't discovered until you begin the installation. Fortunately, I didn't drain the system yet...

I PURCHASED THIS FOR A 2008 PONTIAC GRAND PRIX. IT HEATS UP VERY WELL BUT THERE IS A PROBLEM I HAVE. I DON'T KNOW IF ITS A PROBLEM WITH THIS MODEL CAR OR OTHERS BUT MY CKECK ENGINE LIGHT COMES ON INSTANTLY AFTER I START THE CAR AFTER BEING PLUGGED IN. I DID SOME RESEARCH AND IT LOOKS LIKE THE COMPUTER SEES TO BIG OF A DIFFERENCE BETWEEN THE COOLANT TEMPERATURE AND THE AIR TEMPERATURE SENSORS. I'VE NEVER TAKEN THE CAR IN TO SEE IF MY SENSORS ARE OUT OF CALIBRATION SO I JUST LEFT IT ON THE CAR AND DON'T USE IT. I SHOULD MENTION VERY EASY TO INSTALL.

Bold and Beautiful on the side of my 666 IH Tractor- 1500 watts warms it up to start pretty fast on cold days- good buy. I did have to buy some hose and fittings to make it fit but no big deal. Reason- cold needs to be low- and hot high- heater is installed below the low block drain and then hot goes up to the head, really good circulation!

the difficulty was about a 5 out of ten. then found out the unit did not work at all when the weather got cold.
