Worst customer service and experience and Constantly pointing the finger at the customer while simultaneously admitting to bad parts or lack of experience with leaking parts. WE DO NOT RECOMMEND THIS SUPPLIER.

We’re sorry that your experience with these systems and the support process has reached this point.
We understand the frustration caused by repeated leaks, the additional labor involved in diagnosing and repairing them, and the fact that the issue remained unresolved despite multiple conversations with both our team and the manufacturer.
Our intention throughout was to understand why your installations were experiencing repeated failures and to find a lasting solution, not to place blame on you as the installer. We can also understand how some of the questions asked during troubleshooting may have come across that way, particularly after you had already spent significant time dealing with the issue.
We take your feedback seriously and are continuing to review the matter with the manufacturer, including the outstanding concerns around the repeated failures and associated labor.
We’re sorry we were not able to provide the level of resolution and confidence you expected from us.

Not An Above-The Board Company
I would rate this company 0 stars were I able to. Listing error and refusal to take responsibility for that error and issue me a refund led to me filing PayPal and Visa disputes. 10-15 percent more expensive than competition on Google Shopping. In addition to a short 14-day return policy, a 20 percent restocking fee, transaction fee of 3.5 percent, and handling fee are buried in their terms and conditions. I recommend giving this company a hard pass. Grateful to PayPal and Visa!

Hello Richard,
Thank you for your feedback. We’re sorry the ordering experience caused frustration.
After reviewing the order history, website setup, and communications, we confirmed that the unit shipped matched the configuration selected at checkout. The Nomadic X2 listing included voltage options, with 12V as the default. The 24V option needed to be manually selected, and the chosen configuration appeared in the cart, checkout, and order confirmation email.
We understand you believed the listing described a multi-voltage unit, and we regret any confusion. However, our review found no incorrect or duplicate listing, and the order was fulfilled as submitted.
As a goodwill gesture, we reviewed the case with management, authorized the return after shipment, coordinated return instructions, and reduced the restocking fee from 20% to 10%.
We’re sorry the situation escalated and appreciate your feedback. We’ll continue reviewing our product pages and checkout process to improve clarity.
Kind regards,
Heatso Support Team

Read the return policy
Read the return policy! First they ignored my request for return from the online form, then I had to go through multiple steps to get my return. Filled out a form. Sent it email AND with the item. Then they kept nearly 20% of my purchase.

Heatso must be writing these reviews
Heatso must be writing these reviews. I have never dealt with such an immature, incompetent company in my life. First your product with get stuck in customs, they don’t tell you this and do zero to help. Then, no directions that are detailed enough to do the install (false advertising). And if you call or email them, they only work a few hrs a week so they do not reply until it is very, very convenient for them. I have ran businesses for 25 years and have no idea how they stay in business while having such contempt for the people supporting them. I am now resorting to writing the manufacturers they rep and telling them of my experience. Then a call to my attorney. Avoid at all cost. It has now been 3 months and between customs, wrong heater sent and missing parts, still no heater. Told them I am living in vehicle in winter… they could care less.

Hello Joel,
Thank you for the review!
US customs tend to delay shipments that are high in value. When a shipment is delayed, we receive a delayed notification from FedEx and then provide the requested information to them the same day we receive a request. In this case, personal information was requested and we did contact you about the delay and the reason behind it.
During the start of the communication that you had with our sales representative, all manuals related to the purchase were provided so you could take a look before ordering. The same manuals were provided in the shipment itself.
As for communication, we're very sorry we were not able to get back to you promptly. To avoid similar cases, we've already taken appropriate steps.
We'd like to apologize that our service did not meet your expectations.
We'd also like to point out that when a wrong heater was purchased, we sent the correct one to you without applying any additional charges. We did our best to resolve the issue as quickly as possible and in your favor.
A member of our team will contact you so be sure to provide us with feedback on how we could improve our services.
Thank you and take care!
Best Wishes,
Heatso Team

Sent a defective control unit
Sent a defective control unit. Company would not reply to emails or phone calls. Bought another unit from HeatMyRv and system worked as it should.
Heatso finally reached out and said they will refund the cost of the unit. As soon as I see the credit I will update my experience with them.

We appreciate the feedback you've provided as it helps us greatly to improve our services.

Company Support
I ordered a control unit for my Aquahot. It was promptly shipped. However, after about 10 cycles, it was malfunctioning. After a number of very unhelpful emails from their technical support team in the UK, I was told it was my fault for not doing more research into their product’s limitations. This story was echoed by their technical support here in USA. This unit has a terrible history of reliability dating back 3-4 years but they were only too ready to assign the blame to me. Courtesy and technical support definitely lacking. I will not buy from them again.

Hello Alec,
We apologize if the communication you received from our technical support was lacking.
Unfortunately, we did not manage to complete the diagnostics procedure and offer you a proper solution due to a halt in our communication. To avoid cases like these, our company offers free consultations with our support team before the initial purchase is made.
We're very sorry to hear that you're no longer interested in using our services but we greatly appreciate the review you left as it helps us improve our services in areas indicated by the customer.
Best Wishes,

Customs duty nightmare with no response
Ordered the new petrol air heater for my van. The heater came quickly and I was happy with the customer service as I installed it. Questions were answered pretty quick via email. The heater is great. The issue I'm having is that I am being charged customs fees of $110 because Heatso included an itemized invoice to Fedex that is completely incorrect. They seemed to pick a number out of thin air ($244.55) and said 9 items had that value. What a coincidence! A clamp is valued at that much, as well as the outlet fitting, and the plastic covers for the heater. The heater itself is valued the same amount, as is a standpipe and a bracket. The items I'm being charged customs fees on are NOT the heater, but items that should have been significantly cheaper. So, I'm being charged customs on items valued at $1767, but am not being charged customs on the heater (valued at $244.55). Had they just included an accurate invoice I would have owed probably $100 less. I emailed them and called them, requesting an accurate invoice with no response. And if I understand correctly, I will need to go through them for warranty service, not Eberspacher, which I'm not happy about.

I recommend taking your business elsewhere
I will advise against buying anything from Heatso, rarely have I been this disappointed with a company and its so-called customer support.
First issue came right after ordering. I ordered a hydronic heater kit online late last year, and seeing as Brexit was getting close, I made sure to only order items that where in-stock and able to be shipped quickly. Ten days after placing the order, I had not heard anything from Heatso, so I contacted them, only to be told that the main furnace was on back order. They proposed to downgrade to a smaller furnace which was in stock, which I accepted (but got no compensation for).
The items arrive and one of the additional items I have ordered beside the kit was missing. I wrote to their customer support saying that there is an item missing to which they reply that it is there, and I should go check again. I comply and check again, but the item is simply not there. How ever I find out that I do not need the item for my installation, so I write to Heatso that the item is in fact missing, but I can get on with my installation none the less. (got no compensation here either)
Then when I finally get the kit installed, the water circulation pump vibrated like crazy, and the expansion tank was leaking. I sent Heatso pictures of the hole in the expansion tank, to which they replied that there should be an overflow hole, despite the pictures clearly showing the overflow pipe and an additional hole that was a fault of the plastic molding process. Eventually they sent a new tank which they “forgot” to label as a replacement part, so I had to pay import tax for it.
The vibrations from the circulation pump were so loud, that you could barely hear the furnace running let alone the ticking of the diesel pump. After MANY mails back and forth with customer support, they agree to exchange the pump providing that I send the old pump to them. I sent the old pump the next day and waited…and waited…and waited. Then 14 days after I could see on the track and trace that they had received the old pump I wrote and asked when I could expect to receive the new pump, they replied that I would get the new one as soon as they received the old one. I then provided them with track and trace information showing that they HAD received the old pump 14 days ago, and since then they have stopped answering my emails.
In short, my recommendation is to take your business elsewhere. Other sources might be more expensive but buying at Heatso is a lottery ticket.
After I posted this review, Heatso contacted me and apologized for the delay and said they would ship a new water pump "within the day". Twelve days later (according to tracking info) they shipped the new pump, over a month after they had received my return pump.
