Money Back Guarantee

On certain products an unconditional Money Back Guarantee is offered. Experience has shown that only in isolated cases will our product range fail to solve the problem encountered. If, having installed the product correctly, the problem still remains, simply return it to the place of purchase within a reasonable period of time, with full proof of purchase, for a full refund.

The MBG applies to all products with the MBG symbol displayed. The guarantee will not apply where a product has been subjected to temperature in excess of the recommended operating temperature and where excessive wind speeds are experienced, or where it can be shown unseasoned wood has been burnt. The offer does not affect your statutory rights.
This Rotorvent and its predecessor models has been in production and use for over 20 years and many tens of thousands have been sold and installed to solve chimney problems. The Money Back Guarantee will provide the return of the purchase value by the seller if the Rotorvent does not solve the problem of downdraught.
Although Rotorvents are manufactured to the highest quality standards from premium grade materials, experience has shown that there are parameters against which the product will reasonably perform.
Accordingly the Rotorvent Turbolite should not be used in the following circumstances:

When the flue temperature can exceed 250 degrees celsius
When installed on a short chimney- 4m or less in height
When wet or unseasoned wood is being burnt

If having read the above, you believe that the product is not appropriate for your anticipated use, there are other options. Colt Cowls manufactures a wide range of static anti downdraught cowls which will very satisfactorily resolve most widely encounterered chimney problems.
