Customer Reviews
Quick delivery, perfect part
Needed a new glow pin for my Airtronic D4. Ordered it from Esparparts. It shipped fast. Got the right part. Heater is working again. Simple and good.
Solid quality, good service
My recent purchase from Esparparts was a Hydronic M-II heater and several installation accessories: a fuel pump, wiring harness, and an EasyStart Pro controller. Ordering was straightforward on their site; I found all the components I needed easily. Shipping took 5 business days to reach my location in Oregon, and everything was well-packaged without any damage. I had a question about the controller's compatibility with an older sensor, so I used their online chat. The representative was knowledgeable and provided a clear answer quickly. The heater and parts are genuine Eberspaecher and function exactly as expected. Installation was smooth with the correct parts. It's a reliable setup, just what I needed for my truck.
Good heater, took a bit long
I ordered an Airtronic S2 D2L for my van a few weeks ago. The website was easy enough to navigate. It took about 6 days to get here after I placed the order, which was a little longer than I hoped, but it arrived in good shape. Got it installed and it works well.
Absolutely fantastic service!
I just received my new Hydronic L-II heater kit and it's incredible! The whole process was so smooth from start to finish. Finding the right kit for my marine application was easy, and the checkout was a breeze. Shipping was fast, and the kit arrived perfectly packaged with all the marine thru-hull fittings and insulated exhaust socks. The quality is top-notch, exactly what I expected from Eberspaecher. I can't wait to get this installed and warm up my boat. I will absolutely buy from Esparparts again and tell everyone looking for heaters to check them out!
Always reliable for heater parts
This isn't my first time buying from Esparparts. I've bought several burner inserts and various small components over the years for my fleet of trucks. This last order was for a couple of new fuel filters and a combustion air blower. Just like before, the parts were exactly what I needed and arrived within the stated shipping window. Their consistency is why I keep coming back. I know I'll get genuine parts and no surprises. It's comforting to have a go-to for these specific items.

Does anyone know if they stack discounts? I have a military discount but also saw something about free shipping on kits. Can I use both?
What's their return policy like if I accidentally order the wrong fuel pump? Is it a hassle?
Any chance of a holiday sale coming up soon? Trying to time my purchase of a Hydronic D5 heater.
I'm looking at the Airtronic D4, but also saw some Webasto heaters. Any strong opinions on which one is better for a truck sleeper? Heard good things about both.
Hey, wondering if these Eberspaecher parts are the real deal? Saw some cheaper ones on Amazon but wanted to check if these are genuine or just knock-offs.
Thinking about getting an open box heater to save some cash. Are they usually in good condition? Like, almost new or more like 'some assembly required'?
What's the typical shipping time for a heater kit to, say, Seattle? Trying to figure out when I can get my van conversion project started.
