Warmth, where your project calls for it.

Dimplex Optimyst Direct-wire Heater Accessory — CDFI-TMHEAT

Bring supplemental warmth to a documented Optimyst Pro installation with a separate 1,000W fan-forced heater. CDFI-TMHEAT can be used with the named Pro 500 and 1000 cassettes or as a standalone heat source.

The heater is a distinct part of the project: it does not create water vapor, supply flame media or turn every Optimyst enclosure into a compatible system. Keep the exact cassette generation and installation arrangement together when planning the connection.

A ten-foot extension wire supports remote operation through the cassette. Built-in overheat protection and a compact body support the installation, while the 120V hardwired connection should be planned with the installer.

The right connection starts with the right model.

Let’s get your project right.

Which Optimyst cassettes does this heater sheet name?

The exact CDFI-TMHEAT sheet names CDFI500-PRO and CDFI1000-PRO. It describes use with an Optimyst Pro 500 or 1000 cassette, or as a standalone heater. A similar RGB product name does not establish compatibility with a newer cassette or enclosure.

Does this accessory create the flame effect?

No. This is a fan-forced electric heater. The water-vapor flame effect comes from a separate compatible Optimyst cassette. Adding this heater does not supply a cassette, water system or decorative log set.

How is it powered?

The manufacturer specifies a 120V hardwired supply and 1,000W heat output. Have the electrical and installation requirements checked for the actual project. Do not treat a plug kit for a different Dimplex appliance as a verified conversion for this heater.

Can I operate it without an Optimyst cassette?

Yes. The product sheet describes standalone use as well as installation with the named Pro cassettes. The installer still needs to follow the heater’s own placement, connection and access requirements.

Does the ten-foot wire mean a separate handset is included?

The catalog describes a ten-foot extension wire for remote operation through a cassette. That does not establish a separate handheld remote in this accessory package. Plan control integration around the exact cassette and heater documentation.

Will this heat an entire home?

This 1,000W fan-forced heater is intended for supplemental warmth. The manufacturer describes up to 400 square feet; actual performance depends on insulation, ceiling height, climate and room layout. Size the primary heating system separately.

Are the carton measurements the installed size?

No. The product sheet separately lists carton measurements. The catalog body dimensions are 15 inches wide, 7.75 inches high and 3.4 inches deep. Installation clearances and the surrounding assembly must come from the heater instructions, not its shipping carton.

Can I add it to a current RGB Pro Box because both use Optimyst?

Do not infer that combination. This exact sheet documents the CDFI500-PRO and CDFI1000-PRO generation. A current RGB enclosure can have its own heater arrangement; match the complete system model before adding another heat source.

What protection is documented for the heater?

The product sheet lists built-in overheat protection. Keep airflow and service access clear as required by the installation instructions. A safety cutout does not remove the need for correct placement and electrical installation.

What should I keep for future support?

Keep the CDFI-TMHEAT model number, purchase record, installation information and any connected cassette model. The exact product sheet lists a one-year accessory warranty; coverage for a separate cassette or enclosure is a different matter.

CONFIDENCE BEYOND THE FIRST FIRE

The right fit. The right support.

The exact CDFI-TMHEAT product sheet lists a one-year accessory warranty. Keep the model and purchase record for support; separate cassette and enclosure coverage is distinct.

Tracking your order

Look for your shipping confirmation email for tracking information when your order ships. Items may arrive in separate shipments. Carrier delivery dates are estimates; contact us if you need help checking your order’s status.

Curbside delivery

Large or heavy products may arrive by freight. Standard freight delivery is curbside: plan for help moving the shipment from the curb to its final location. Carry-in service, assembly, installation and packaging removal are not part of standard curbside delivery.

Hassle Free Returns

Return requests must be made within 7 days of receiving your order. Call or email us with your order number and the item you would like to return.

You must contact us in advance to arrange return pickup. Please do not send items back without first arranging the return with us.

There is no restocking fee. For change-of-mind returns, customers are responsible for return shipping costs, which will be deducted from the refund. Customers do not pay return shipping for damaged items.

Keep the original packaging and all parts and accessories. If you’re considering a return, leave the product unused and uninstalled while we review your request. Custom-made items are identified on the product page before adding to cart and before order confirmation. Custom items cannot be returned for change of mind. Damaged-item support still applies.

Call or email us with your order number to request a cancellation.

Refunds

Approved refunds are issued immediately upon inspection of the returned item, to the original method of payment used for your order. Once we issue your refund, it usually takes 7–10 days for the credit to appear in your account. The exact timing depends on your credit card issuer, bank or payment provider and their processing policies.

This timeframe begins when the refund is issued, rather than when a return is requested or shipped. For change-of-mind returns, return shipping costs will be deducted from your refund. Customers do not pay return shipping for damaged items. There is no restocking fee.

If your refund has not appeared after 10 days, check your account or card statement and contact your bank or payment provider. If you still need help, contact us with your order number so we can help check the status.
