Specifying a Tiileri masonry heater
All six Tiileri models fall under standard EN 15250:2007 and are documented by their manufacturer. This page brings together the data that can already be published; the manufacturer’s documentation is sent to you on request, until the full specifiers’ area is available.
Data that can be published so far
| Model | Catalogue weight | Nominal output | Efficiency (DoP) | Safety distances (DoP) | Declaration of performance | |
|---|---|---|---|---|---|---|
 | Heidi | 450 kg | 8.2 kW | [TO BE CONFIRMED] | Below the cooking surface: 50 mm at the back and sides. Above the cooking surface: 500 mm at the sides, 1,000 mm upwards. 50 mm to the floor | RRF-50 23 6334 (shared with the Helmi) |
 | Helmi | 850 kg | 8.2 kW | 77% | Below the cooking surface: 50 mm at the back and sides. Above the cooking surface: 500 mm at the sides, 1,000 mm upwards | RRF-50 23 6334 |
 | Aida | 1,130 kg (h. 1800) | 1.4 kW | 91% | 50 mm at the back, 50 mm at the sides, 150 mm above | RRF-50 21 5712 |
 | Aino | 1,190 kg (h. 1950) | 1.4 kW | 91% | [TO BE CONFIRMED] | RRF-50 21 5712 |
 | Sofia | 1,950 to 1,980 kg | [OUTPUT: TO BE CONFIRMED] | 88% | 50 mm at the back, 50 mm at the sides, 150 mm above | RRF-50 21 5713 |
 | Amanda | 2,110 to 2,240 kg | [OUTPUT: TO BE CONFIRMED] | 88% | 50 mm at the back, 50 mm at the sides, 150 mm above | RRF-50 21 5713 |
Safety distances: minimum distances between the heater and combustible materials.
Standard
EN 15250:2007: slow heat release appliances fired by solid fuel, for domestic heating. It applies to all the heat-storing stoves in the range.
Declaration of performance (DoP)
The manufacturer’s document stating the declared performance of the appliance under the standard. Three declarations cover the range: RRF-50 21 5712 (Aida and Aino), RRF-50 21 5713 (Amanda and Sofia), RRF-50 23 6334 (Helmi and Heidi).
Built-in firewall (Sofia, Amanda)
The declaration of performance gives 50 mm at the back; the Finnish catalogue gives a rear safety distance of 0 mm for the version with a built-in firewall. This distance is not yet published in the French documentation: to be confirmed for each project.
AirBox
Ducted combustion air supply, available on Helmi and Heidi — earlier factory catalogues say otherwise and are out of date on this point.
Not yet published
- Stored energy and heat release time of Aida and Aino: [TO BE CONFIRMED], the manufacturer’s sources disagree.
- Nominal output of Sofia and Amanda: [OUTPUT: TO BE CONFIRMED].
- Efficiency of the Heidi and safety distances of the Aino: [TO BE CONFIRMED].
- Floor loads and supporting floor specification: no general specification. The load-bearing capacity of the floor or slab is assessed project by project.
- Model specification clauses for a CCTP (cahier des clauses techniques particulières, the French technical specification in tender documents): available soon, on request in the meantime.
We would rather leave a box empty than publish a value not confirmed by the manufacturer.
Key points
- Standard EN 15250:2007 across the whole range, three declarations of performance.
- Built-in firewall on Sofia and Amanda; AirBox available on Helmi and Heidi.
- Supporting floor and conflicting values: assessed case by case.
