Installation
A chimney that already serves a boiler or an older stove is not automatically available for a second appliance, and the sentence that settles it is rarely on the listing. What matters is the appliance type: a firebox whose door closes itself cannot be left open to draw air from the shared flue, and that is the condition under which several countries allow more than one appliance on the same chimney. Manufacturers describe this as type 1 rather than type 2, and the three pages below are the only ones in this catalogue where the claim is made in the listing itself. It is not a substitute for the sweep’s approval — that is a local decision about a particular chimney, its cross-section and its height — but it is the difference between an appliance that might be permitted and one that certainly is not.
A shared flue works because every appliance on it stays closed to the room while the others draw. A self-closing door is what guarantees that when somebody walks away mid-load, and it is the reason the distinction between type 1 and type 2 exists at all.
An appliance whose door stays open where it is put is not a worse appliance. It is one that has to have the chimney to itself.
A maker can state that the appliance is built for multiple connection. It cannot state that your chimney will take it, because that depends on the section, the height, the draught and what is already connected.
The three pages here are the only ones in this catalogue where the first half of that is written in the listing rather than left to be assumed. The second half belongs to whoever signs off the installation where you live.
Most pellet stoves are fan-driven, which puts the flue under positive pressure rather than letting the chimney pull. A system built for natural draught is not sealed for that, and a shared flue carrying both regimes is a question for a specialist rather than for a listing.
One pellet appliance in this catalogue states multiple connection. That statement and the pressure question are two different things, and both have to be answered.
7 kW, soapstone, self-closing door, multiple connection approved
The only appliance here approved for multiple connection and for coal, with an automatic air regulation for continuous burning and optional storage stones.
Best for: An installation where a shared flue is already the situation and the maker’s approval is what is needed
Fully automatic, Wi-Fi app, ceramic igniter, multiple connection
One dense feature line covering app control, a ceramic igniter and — the notable one — approval for connection to a shared flue.
Best for: An installation where a shared flue is already the situation and the maker’s statement is what is needed
A type 1 appliance has a self-closing firebox door; a type 2 door stays where it is put. The distinction exists precisely because a shared flue must not be opened to the room by one appliance while another is drawing on it. Where a listing states type 1 and multiple connection, the page prints it; where it states type 2, the page prints that too.
No. It means the appliance is built for it. Whether a particular chimney can carry two appliances is a calculation about that chimney — its section, its height, the draught it produces — and in most places it is signed off by the sweep or the inspector. The listing statement is a necessary condition, not the decision.
One listing in this catalogue states that it is suitable for multiple connection, and it is on this page. It is worth reading carefully: pellet appliances are usually fan-driven, which puts the flue under positive pressure, and a system built for natural draught is not sealed for that. The two questions are separate and both have to be answered.
For : An installation where a shared flue is already the situation and the maker’s approval is what is needed
Main strength : The only appliance in this family stated as approved for multiple connection
Main limitation : No efficiency figure on the most expensive appliance in this family
For : An installation where a shared flue is already the situation and the maker’s statement is what is needed
Main strength : Stated as suitable for multiple connection, which almost nothing on this shelf claims
Main limitation : No output figure at all, on an appliance at the upper end of this family’s prices
Head-to-heads already published between two models from this guide or this aisle.
The models here come from the catalogue of this site. Specifications are those published by the manufacturer and on the Amazon product page; prices are what Keepa reported on the date below, and both move. The ranking uses declared specifications, the balance of stated strengths and limitations, and price. No product on this site has been physically tested, and nothing here claims otherwise.

Wood heating is bought when the house is already cold, and that is the worst moment to judge a figure: demand for this shelf climbs through the winter and falls away in spring, so a struck-through price in November tells you nothing at all about what the same reference cost in June. UniverTrack keeps a weekly history for each retailer, so a discount is weighed against a figure somebody actually paid rather than one composed for the banner — and it says when ordering is genuinely the moment.
