Our take on Modine for greenhouse applications Modine stands by their warranty which isn't the case for many heater manufacturers due to humidity typical of greenhouse environments. Don't get us wrong, there are other manufacturers that manufacture solid gas fired heaters, but none we've found that can beat the value of the Modine PTP series on price, and the PTC line for efficiency (93-97%) in relation to price. The 10-year heat exchanger warranty is hard to beat, and the polyester paint is corrosion resistant which does well in a greenhouse.

The PTP series features a stainless steel tubular heat exchanger which comes with a 10-year heat exchanger warranty. The PTP series is horizontally vented and offers good value considering the efficiency rating, durability, and warranty at this price. The PTP delivers 80% thermal efficiency in a robust package of design features, including:

  • 10-year heat exchanger warranty
  • Built to accommodate greenhouse environments
  • 400k BTU/hr input, 320k BTU/hr output at up to 2000ft elevation
  • Seven model sizes available ranging from 150,000 to 400,000 BTU/hr
  • Standard stainless steel heat exchanger extends the life of your heater
  • Permanently-lubricated fan motor outside the cabinet is standard for troublefree dependability and is enclosed to limit exposure
  • Tubular heat exchanger design is dependable and efficient
  • Power exhauster and controls are mounted inside the cabinet for maximum protection from moisture and dust making it a great fir for greenhouse environments
  • An easy access controls section makes the PTP models easy to install
  • For lower BTU requirements, the Hot Dawg is available from 30,000 - 125,000 BTU/hr (stainless steel heat exchanger is optional)
  • The PTP series features baked on polyester paint with excellent corrosion resistance in neutral tones.

Heater Maintenance Checklist

BTU Primer Most manufacturers advertise a heaters input BTU which is the amount of fuel a heater consumes per hour. To get what matters, your output BTU, simply multiply your input BTU by your efficiency. In the case of the PTP 400, we multiply 400,000 x .80 (80%) which gives us an output of 320,000 BTU/hr. Elevation lowers heater effectiveness. Above 2000ft elevation, for every 1000ft reduce your output rating by 4%. For example, the PTP 400 at 4000ft elevation would output 294,400 BTU/hr.

Any product listed with the blue delivery truck has Free Shipping

Be aware only products with the blue free shipping symbol have free shipping. All other products have quoted shipping.

For all products not marked with the free shipping icon, we will calculate shipping and get in touch with you with a shipping quote before finalizing your order.

Greenhouse and commercial greenhouse equipment shipping costs are calculated separately from the rest of your order. These items are mainly greenhouses and large/heavy commercial items that require freight shipping. This allows us to get you the lowest rate possible based on your proximity to our manufacturing facility.

We will be sure to get you a prompt shipping estimate and invoice once you are ready to purchase! We will reach out by phone or email whenever an order or quote request for a greenhouse or commercial greenhouse equipment is submitted. Our fast and friendly staff wants to make sure you get the best rates and make sure that your order is complete and accurate before it gets sent out!

$500 minimum on all orders!

Hortitech Direct keeps prices competitive and products delivered efficiently by having minimum orders of $500. Contact support if you have questions!

Lead Times

We do our best to get you your order as quickly as possible.  Be aware, however, that shipping in the commercial greenhouse industry can be unpredictable due to seasonality. Our priority is to keep costs down and pass those savings on to our customers. Although we do our best to get orders shipped out as quickly as possible please account for the possibility of shipping delays for this reason. We are manufacturers ourselves and work directly with manufacturers as much as we can. To keep costs down we aggregate shipments.

Damaged Shipments!!!

Inspect all items on arrival: Drivers MUST sign if ANYTHING is damaged due to handling during shipping before they leave your property. You cannot return or be reimbursed for items damaged during shipping without a signed receipt from the driver.

Parcel Shipments

For smaller parcel shipments your order will be delivered by UPS, FedEx, or USPS and will generally ship and arrive in a predictable fashion. We will supply you with a tracking number as soon as your order is shipped.

Standard Freight

Larger orders ship out by freight on one or more palettes.

Freight Agreement

Freight Friendliness Required: Your location must be able to accommodate freight. Semi-trucks vary in size and can be as long as 80ft and sometimes require room to turn around to head out of your location.

Presence Required: An authorized person must be present to accept and unload freight shipments.  If special equipment is required to unload freight shipments such as a forklift or palette jack they must be supplied by the customer.

Extra Delivery Fees: Some orders incur additional delivery fees due to limited accessibility. This can include busy city centers, Hawaii, Alaska, other islands, or inaccessible areas. We will contact you prior to charging additional shipping fees for your approval. At rare times our freight agents will contact us about additional costs they incur which must be paid prior to delivery due to "obvious" barriers to delivery. Again in these rare circumstances, we'll get in touch with you to find a resolution that is fair to all involved. If you have any questions about shipping feel free to get in touch with us!
