Duda DieselInsPHS Small Foam Insulated Silicone Pail Heater Adjustable Thermostat 400W 110V/120V 790 mm x 102 mm, 4" Height, 0.3" Width, 31.1" Length

Nice small easy to handle heater…it did not heat fast enough for my needs, but I am keeping it anyway because it is a great product well made for slow steady heating…I tried Warmguard 5gal.Heater first, but prefer this one because of the thermostat/switch, sturdiness of the insulated material and it’s size for my old hands with old injuries…the insulated option is worth the minimal extra cost, since it also keeps the heater cool to the touch from the outside as well as insulates against the colder outside temps. It stays in place and fits those regular 5 gal. Buckets very well. Rolls up small for storage. Not fragile in any way.

Wanted to give a ONE star for couple reason. First discription says it's fit a 5 gallon pail. Yes it does if you attach heater belt all the way to the bottom of pail and even then I had to use a pliers to stretch the springs to fasten it. Heater belt could / should be longer. Or longer springs provided. Now due to excessive spring tention the next morning one of the spring fastening clips tore out and heater was only holding on by lower spring....NOW per the quality and function of heater itself I'd give it 5 star. Easily kept a completely filled bucket at 110° F ( setting dial at 90) at an ambient temperature of 27°F. So it works perfect for what I wanted it for. Returning broken one to Amazon and reordered a replacement due to spring clip breaking but going to Auto store and purchasing longer springs for it.

This thing is HOT! At nearly 800W it pulls a serious amount of power and heats up quickly, literally within seconds it's hot to the touch. I don't know how many amps it is pulling but it has blown the 15 amp fuse on our panel a few times when I wasn't paying attention to what other items were running on the same circuit. Even though it heats up quickly it's not very efficient because of the lack of insulation. I notice that a lot of heat is lost to the air around the bucket. It does a much better job with some insulating material wrapped around the bucket after you've placed this on. Just make sure that whatever you use is able to tolerate the amount of heat this thing puts out. Once I wrapped a tarp around the outside of the bucket over the top of the pail heater the contents heat up quickly and stay at a fairly constant temp with the built in thermostat. One other issue is the smell...it smells strongly of machine oil and solvents from the silicone. Over time the smell has lessened but initially I was surprised by the amount of chemical odor when I first turned it on and every time I plug it in.

My first band was busted when it came in, but after an email to customer service, another was quickly dispatched! I use this to warm a pressure pot for resin casting. Very effective and useful product.

Does NOT fit a standard five gallon bucket. Had to find a slightly smaller rounded bucket to fit. Temperature gauge is in celsius. Use it to clean deer skulls. Slightly annoying how doesn’t fit the bucket.
