Pellet stoves

Nearly Twenty Years of Pellet‑Heating Expertise

We at Gondwana Green Heat have been fitting pellet stoves for almost 20 years. In the early days, pellet heating had a slow start in the UK compared with our continental neighbours — largely due to traditional tastes and hesitation around new technology.

Those barriers have now been overcome. Manufacturers such as Island Pellet Stoves in Wales have transformed the market by producing pellet stoves that look and feel like classic wood burners, complete with a natural flame pattern. We are proud to be the dedicated Scottish dealer for Island Pellet Stoves, supplying, installing and maintaining their high‑quality UK‑made room‑heating and boiler stoves.

We also continue to work closely with MCZ of Northern Italy — one of Europe’s most respected pellet‑stove manufacturers — offering a stunning range of contemporary and innovative pellet stoves and pellet boiler stoves.

The Three Types of Pellet Stove We Offer

We supply and install three distinct categories of pellet stove, each suited to different homes, heating needs and design preferences:

  • Room‑heating pellet stoves
  • Pellet boiler stoves
  • Ducted pellet stoves

A room‑heating pellet stove is essentially the same concept as a conventional wood‑burning stove, but with the added convenience of running on clean, consistent wood pellets rather than logs. It gives you the same flame view, the same comfort, and the same focal‑point presence in the room — but with automated control, higher efficiency and far easier day‑to‑day use.

A room‑heating pellet stove:

  • Burns standardised wood pellets with low moisture content
  • Uses an onboard computer to light the fire automatically and maintain your chosen temperature
  • Provides a steady, controlled heat output without overheating the room
  • Requires minimal daily maintenance
  • Offers very low emissions, typically far lower than modern EcoDesign log stoves

A ducted pellet stove offers all the benefits of a standard room‑heating pellet stove, with one major advantage: it can move warm air to other parts of your home through discreet ducting.

A ducted pellet stove pushes heated air through insulated ducts, allowing you to warm hallways, bedrooms, loft spaces or adjacent rooms from a single appliance. The ducting can be connected directly to the stove or routed to a discreet wall or ceiling terminal, giving a clean, unobtrusive finish that blends into the home.

This system allows you to distribute heat far more evenly, making a ducted stove an excellent choice for homes with awkward layouts, larger footprints or areas that are difficult to heat.

It’s also worth noting that we can add a ducting system to most pellet stoves, giving customers far more flexibility when designing their heating system.

A pellet boiler stove looks just like a standard room‑heating pellet stove, but it also has the ability to heat water at the same time. This means you can enjoy comfortable radiant heat in the room where the stove is installed and produce hot water for radiators, underfloor heating and domestic hot water — all from a single appliance.

A pellet boiler stove:

  • Heats the room like a normal pellet stove
  • Sends hot water to radiators or UFH
  • Provides tap water via a thermal store
  • Can also be fitted with a ducted air system to distribute warm air around the home

This makes pellet boiler stoves one of the most versatile heating options available, especially when paired with a thermal store or integrated into a hybrid renewable system.

Why Pellet Stoves Are Now Surging in Popularity

We are now seeing overwhelming support for pellet stoves and pellet boiler stoves across the UK, with many customers choosing them over conventional log‑fuelled appliances. The shift is clear: pellet stoves offer a long list of advantages that traditional wood‑burning stoves simply cannot match. From automated combustion and stable, controllable heat to very low emissions, clean fuel handling, high efficiency, and compatibility with modern airtight homes, pellet stoves provide a smarter, cleaner and more convenient heating experience.

Pellet Stoves: Typical Questions We’re Asked

What are wood pellets?

Wood pellets are made from compressed waste sawdust — a clean, renewable fuel with a low moisture content and consistent size. They’re widely available in 10–15 kg bags, or can be blown into bulk storage for larger systems. Pellets are poured into the stove’s hopper, which feeds the appliance automatically.

How much ash do pellet stoves produce?

Very little. The small amount of ash can be used as free garden fertiliser.

How do pellet stoves work?

Pellet stoves and pellet boiler stoves use fully automated combustion. An onboard computer lights the fuel, regulates the burn and maintains your chosen room temperature. You get the flame view and comfort of a wood fire without tending it manually.

How efficient are pellet stoves?

Pellet appliances offer very high efficiency, comparable to other forms of biomass and modern fossil‑fuel boilers. They also provide fuel stability, reducing reliance on global gas and oil prices.

Can a pellet boiler replace my existing boiler?

Yes. A pellet boiler stove can replace a gas or oil boiler while keeping your existing radiators or underfloor heating. You can also add a room‑heating pellet stove as a feature appliance.

Are pellets produced locally?

Yes — pellets are produced here in Scotland, supporting forestry, manufacturing and haulage jobs.

Are pellet stoves carbon neutral?

Pellets are considered carbon neutral, making them a strong renewable‑heat option.

Are pellet stoves cheaper to run?

Installed systems typically cost less to run than LPG, oil or kiln‑dried logs.

Are pellet stoves suitable for rented properties?

Yes. They’re ideal for rural cottages and farm lets where solid‑fuel systems already exist. Automated combustion means no wet fuel, fewer breakdowns and safer operation for tenants.

What sizes do pellet stoves come in?

We supply stoves from 1.5 kW to over 20 kW, covering everything from small rooms to full‑home heating.

Do pellet boiler stoves provide hot water?

Yes. All our pellet boiler stoves are paired with a thermal store, giving mains‑pressure hot water, radiators and underfloor heating.

What styles are available?

We supply tall, squat, round, square, modern and traditional designs. There is a pellet stove for every home.

How clean are pellet stoves?

Pellet stoves have very low emissions — typically ten times lower than a modern EcoDesign wood stove.

Do I need to clean my pellet stove?

Yes, but only minimal maintenance:

  • Around one minute daily
  • Weekly ash‑pan emptying during the heating season
  • Chimney cleaning once or twice per year, depending on use

Do I need a chimney?

Yes. We can use an existing chimney or install a new stainless‑steel system.

Do I need an air vent?

In most cases, no. Over 90% of our installations use a balanced chimney system, similar to a modern boiler flue. Fresh air is drawn through the outer layer of the chimney, pre‑heated, and fed into the combustion chamber — improving efficiency and eliminating the need for a wall vent.

Do I need a hearth?

Yes — a non‑combustible hearth with a minimum thickness of 12 mm.

Will a pellet stove overheat my room?

No. Pellet stoves are thermostatically controlled. Set your desired temperature and the stove maintains it automatically.

What is the biggest output available?

We supply pellet stoves from 1.5 kW up to 20+ kW.

Are pellet stoves suitable for passive houses?

Yes. With a balanced chimney system and thermostatic control, pellet stoves work beautifully in airtight, low‑energy and Passivhaus‑level homes — with no overheating issues.

Poujoulat PGI Pellet Chimney Systems

The Poujoulat PGI pellet chimney system is now our primary choice for pellet‑stove flue technology — and for good reason. PGI transforms a great pellet stove into an exceptional one.

PGI is a balanced‑flue, air‑tight, fully insulated chimney system designed specifically for pellet appliances. By pre‑heating the stove’s combustion air, PGI improves overall efficiency and reduces particle emissions, delivering cleaner, more stable performance.

Because the system is balanced, it is unaffected by wind, ensuring consistent operation even in exposed rural locations. PGI also supports shorter chimney runs and, with approved manufacturers, can even allow horizontal terminations — giving far more flexibility in modern homes.

For low‑energy and Passivhaus‑level buildings, PGI offers a full range of air‑tight, insulated components, making it one of the most advanced pellet‑chimney solutions available.
