New Customers:

We sincerely appreciate the opportunity to serve new customers. In order to provide our customers with the best service possible, we will establish NET 30 DAY terms for new accounts who wish to place an initial order in excess of $300. For customers meeting that requirement, we can normally establish open account status within 48-72 hours after receipt of a purchase order with customer credit information and/or a completed credit application. For new customers who cannot wait for the account to be established or who wish to enter an order for less than $300, we require a credit card to process your first order. New customers may complete a credit application and submit it with their initial order so that NET 30 DAY terms may be established for future orders.

Payment Terms:

NET 30 DAYS with approved credit per provisions and requirements stated above. VISA, MASTER CARD, and AMERICAN EXPRESS are accepted. C.O.D. may be available depending upon product availability, your location and customer’s requested delivery time. For customers with open account status, no other payment terms are available other than NET 30 DAYS. Again, we specifically take exception to and do not acknowledge any other terms stated on a customer’s purchase order or in any communication. In all cases, orders are accepted from customers and entered subject only to the terms and conditions herein.

Minimum Billing:

Thermal Devices minimum order requirement is $50 for standard, in-stock merchandise. However, Thermal Devices is a distributor for many major manufacturers. For products that are non-stock, custom, altered, manufactured to order, etc. Thermal Devices’ minimum order will be consistent with the minimum order requirement placed upon us by the manufacturer of those nonstock products.

Freight Terms:

Thermal Devices freight terms are strictly F.O.B. – ORIGIN (aka – Ship Point) with Shipping & Handling either Prepaid and Added to your invoice or Freight Collect to your open account with a carrier of your choice. As a protection to our customers, it is our policy that all orders with FOB- Origin terms, regardless of whether Pre-pay & Add or Collect to your carrier account, will be shipped and may be insured for an amount, solely at the discretion of Thermal Devices, up to the full amount of the contract price of the order at the customer’s expense using the carrier’s insurance service unless Thermal Devices has an instruction in writing from the customer at the time of order specifically indicating that they do not wish their shipments to be insured. To waive insurance, please complete our Waiver of Insurance document located at www.thermaldevices.com/insurancewaiver and submit with your order or send via e-mail to sales@thermaldevices.com. If your order was placed through our e-commerce system on our website with a discounted (fixed) freight amount, it will NOT be insured unless you specifically request that we insure your shipment. If you do not request insurance, per industry standard FOB-Origin terms, you are responsible for any shipment losses once the material has been transferred to the carrier. If your purchase value is high, you should confirm with your salesperson that you do/do not wish to have the shipment insured for your protection. Please take note that if insurance is refused, any loss after date of shipment will be the customer’s sole responsibility. Our carrier of choice is UPS. However, we would also be happy to ship your order via FEDERAL EXPRESS or DHL. For other carriers or truck shipments, we request that you designate in writing your desired carrier. We will attempt to accommodate all requests regarding customer’s desired carriers.

Customers located, or drop shipping, outside of the 48 continental United States are responsible for any duties, taxes and fees associated with the shipment. Please note that such charges may not be available for billing at the time of shipment. In those cases, Thermal Devices will bill the customer for actual charges when we are notified of those exact costs. Thermal Devices reserves the right to charge a handling fee for special packaging or unusually complicated and time consuming paperwork associated with overseas shipments. However, the customer will always be notified of the amount of the handling fee prior to any chargeable work being performed.


Our experienced packers take every reasonable precaution to prevent damage-in-transit. Should you discover such damage, please make a claim to the carrier as soon as possible. We strongly urge you to photograph and document the exterior of the shipping container for your use in making a claim to the carrier. Please see Freight Terms above for your liabilities related to lost or damaged shipments.


Due to manufacturer price changes, any prices shown in any of our publications or on the internet are subject to change at any time. In all cases we will attempt to update our pricing as soon as possible to avoid any confusion or delays in processing customer orders. Pricing discrepancies could result from reasons including, but not limited to, manufacturer price increases, inaccurate part numbers on our communications or marketing materials, typographical errors, delays in pricing updates, etc. In the event of a pricing discrepancy at the time of order, Thermal Devices will notify the customer and the customer may choose to amend their order with Thermal Devices or cancel the order provided that the order has not been entered or processed by Thermal Devices and the reason for the price increase was not a change in requirement or scope by the customer.

Sales Tax:

Thermal Devices is required to charge sales tax on all orders shipped to delivery destinations in states with online (remote seller) sales tax laws or states in which Thermal Devices has a physical nexus. Thermal Devices customers with a valid tax exempt certificate for orders must indicate so at the time of every order and submit that certificate with their initial application for credit or when placing an initial credit card order.

Order Cancellations:

If an order cancellation becomes necessary, please call us immediately. If the order in question represents only stock product from our warehouse (not a manufacturer or our other supplier’s warehouse) that has not been “picked” to ship at the time of cancellation, there will be no cancellation charge. We will make every effort to have items ordered from a manufacturer or other supplier canceled at minimal expense. However, cancellation charges beyond our control may be imposed by the manufacturer or supplier for which the customer will be solely responsible. Orders for custom designed, custom built products cannot be canceled or returned once the order is entered with Thermal Devices.

Returned Goods:

Should it become necessary to return a product to Thermal Devices, please request a Return Material Authorization (RMA) number from the customer service department. Our receiving department cannot accept returned goods unless they are properly identified. Originally stock products from our warehouse returned in new, un-opened, resalable condition will be subject to a minimum restocking charge of 20% of the original purchase price. Unfortunately, opened or used products may not be returned under any conditions. For all non-stock items, items ordered from our vendors or for custom manufactured products, returns will be subject to acceptance and restocking charges imposed by each individual manufacturer or vendor and the customer will be solely responsible for those charges.

Defective Merchandise Procedure:

Please inspect all merchandise upon receipt. If a customer believes a product to be defective, a claim must be made to the customer service department within 30 days of receipt of product. We will attempt to ascertain the source of the defect and take immediate steps to alleviate the inconvenience to the customer. In most cases, the normal procedure is to return the product to Thermal Devices who will return it to the appropriate manufacturer for evaluation, repair or replacement. In all cases, the manufacturer’s warranty will govern the disposition of the product.

Should no defect be found, the customer may be responsible for any evaluation fees and freight associated with the return transaction. If the customer desires a replacement product immediately, the customer may place a new, distinctly separate order for the replacement part. Upon return of the defective part, Thermal Devices, at our discretion or the discretion of the manufacturer will either repair or replace the defective unit or issue a merchandise credit equal to the amount of the initial invoice less any freight and handling charges. It is our desire to treat our customers fairly and we will make every attempt to handle a return transaction with the best interests of the customer in mind.


By their very nature, most heater products are custom assembled for each customer. Even stock heaters are generally modified with lead wires or other design issues that make such products non-returnable once received by the customer. Therefore, all heaters purchased from Thermal Devices are non-returnable unless they are deemed defective by the manufacturer following a proper return and evaluation as described above. In such a case, the manufacturer’s standard policies or warranties shall govern the solution to the problem.

Please note that Thermal Devices will ship stock heaters in the exact quantity specified on a customer’s order. However, in the manufacturing of non-stock heaters, it is necessary to allow for losses in production. For this reason, we reserve the right to ship as stated below:


1 – 5
6 – 10
11 – 25
26 – 50
51 – 80
81 – 99
100 +


No Variation
+ / – 1 unit
+ / – 2 units
+ / – 4 units
+ / – 6 units
+ / – 8 units
+ / – 5% of order

This is an industry standard manufacturing variation chart with regards to heater manufacturing and all heater manufacturers can generally be expected to follow the guidelines above. Therefore, we urge our customers to be aware that large quantity orders may be over-shipped or undershipped according to the chart above. Over and under shipments are billed at the original purchase price for the final quantity shipped regardless of original quantity ordered and the order will be considered fulfilled and closed.

Quantity Discrepancies:

All quantity discrepancies must be reported with 72 hours of receipt of product. Thermal Devices will not be responsible for quantity discrepancies not reported within 72 hours of receipt of shipment.

Governing Law:

In all disputes or matters arising or related to any purchase or interaction between a customer and Thermal Devices, the laws of the state of Maryland, without regard to principles of conflict of laws, will govern these Terms and Conditions. Customer further agrees jurisdiction and venue with respect to any dispute shall be proper in the state and federal courts of the State of Maryland.
