The Stovax Riva 40 is the smallest in the high efficiency Riva cassette range. Thanks to its size, it is designed to fit into a standard 22" high x 16" wide British fireplace opening. This allows for easy installation into an existing chimney breasts with less building work required.

The Riva 40 has a 4.9kW heat output which is perfect for most rooms and an impressive 80.5% efficiency. This stove meets Ecodesign regulations and is A+ energy rated. The Riva 40 is the only in the range with the ability to burn smokeless fuel, if desired. Developed for outstanding performance, the Riva 40 is an excellent choice for rural and urban homes alike.

Riva2 fires feature a Ri-Ignite Boost mode, allowing a rapid boost to make it effortless to ignite logs, even from a small ember. An advanced DualFlow Airwash system introduces an air flow from the top and bottom of the firebox to ensure a crystal clear view of the flames. There are two sliding air controls making it easy to operate and a removeable ashpan for easy maintenance.

Feel free to contact us for collection information and locations of our warehouses.
Delivery Information:
Your goods will usually be delivered on a 10-tonne vehicle (about the size of a bin wagon). If there is likely to be a problem with access please contact us in advance of placing your order. Examples of areas we cannot deliver to are long or gravelled drives, areas inside walled cities with height restrictions, narrow lanes, grassed lawns, steep drives, narrow gateways or up/down steps. We may be able to make alternative delivery arrangements if you contact us in advance.
With our standard delivery service, there will be one driver, we suggest you have at least one other person with you to assist. The driver will move the goods to the nearest accessible wheel point depending on access. Unfortunately due to insurance and health and safety issues, the driver is not permitted to move the goods inside your property but can wheel them into a garage. 
We advise that you check the goods while the driver is still there. The driver is obliged to wait for up to 10 minutes, (for palletised goods only) whilst you unpack and check the goods. If the driver refuses to wait then please mark the goods as damaged on the delivery note, so you are covered for all eventualities. If you have checked the goods and they are found to be damaged, please mark this clearly on the delivery note and contact our offices straight away.
If you are unavailable when your goods are delivered on your pre-booked delivery date, then re-delivery charges will apply. If you are unavailable when smaller packaged goods (eg. Stove Glass) are delivered, the courier company will leave a note, explaining how to re-arrange delivery for a more convenient time.
