Pellet Stoves

A wood fire that lights itself, holds its temperature, and goes out when the room is warm.

Nearly twenty years of pellet heating

The barriers have gone

We 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 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 supply, install and maintain their UK‑made room‑heating and boiler stoves in Scotland.

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

We are now seeing overwhelming support for pellet appliances across the UK, with many customers choosing them over log‑fuelled ones: automated combustion, stable and controllable heat, very low emissions, clean fuel handling, high efficiency, and compatibility with modern airtight homes.

Three kinds

Which one depends on what you need heated

Room‑heating

A wood stove that lights itself

The same concept as a conventional wood‑burning stove, running on clean, consistent pellets rather than logs. The same flame, the same focal point — with automated control, higher efficiency and far less to do each day.

  • Burns standardised pellets with low moisture content
  • An onboard computer lights it and holds your chosen temperature
  • Steady, controlled output without overheating the room
  • Minimal daily maintenance
  • Very low emissions, typically well below a modern EcoDesign log stove

Ducted

Warm air, moved where you need it

Everything a room‑heating stove does, plus insulated ducting that carries warm air to hallways, bedrooms, loft spaces or adjacent rooms from a single appliance — direct from the stove, or out to a discreet wall or ceiling terminal.

  • Distributes heat far more evenly through a house
  • Suits awkward layouts, larger footprints and hard‑to‑heat rooms
  • Can be added to most pellet stoves, not only purpose‑built models

Boiler stoves

Heat the room and the water

It looks like a standard room‑heating stove, but it heats water at the same time — radiant heat where it stands, and hot water for the rest of the house.

  • Heats the room like a normal pellet stove
  • Sends hot water to radiators or underfloor heating
  • Provides tap water via a thermal store
  • Can take a ducted air system as well

Poujoulat PGI

The chimney makes the stove

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

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

Because it is balanced, it is unaffected by wind — which matters in exposed rural locations. It also supports shorter runs and, with approved manufacturers, horizontal terminations, giving far more flexibility in modern homes.

For low‑energy and Passivhaus‑level buildings, PGI offers a full range of airtight, insulated components.

Typical questions we’re asked

Everything people want to know first

What are wood pellets?
Compressed waste sawdust — a clean, renewable fuel with low moisture content and consistent size. Widely available in 10–15kg bags, or blown into bulk storage for larger systems. Pellets are poured into the stove’s hopper, which feeds the appliance automatically.
How much ash do they produce?
Very little. The small amount there is makes free garden fertiliser.
How do they work?
Fully automated combustion. An onboard computer lights the fuel, regulates the burn and maintains your chosen room temperature — the flame view and comfort of a wood fire, without tending it.
How efficient are they?
Very. Comparable to other forms of biomass and to modern fossil‑fuel boilers, with the added benefit of fuel stability rather than exposure to global gas and oil prices.
Can one replace my boiler?
Yes. A pellet boiler stove can replace a gas or oil boiler while keeping your existing radiators or underfloor heating — or you can add a room‑heating stove as a feature appliance alongside it.
Are pellets produced locally?
Yes — here in Scotland, supporting forestry, manufacturing and haulage jobs.
Are they cheaper to run?
Installed systems typically cost less to run than LPG, oil or kiln‑dried logs.
Do they suit rented properties?
Yes, particularly rural cottages and farm lets where solid fuel is already in use. Automated combustion means no wet fuel, fewer breakdowns and safer operation for tenants.
What sizes are available?
From 1.5kW to over 20kW, covering everything from a small room to a whole house.
Do boiler stoves give hot water?
Yes. All of ours are paired with a thermal store, giving mains‑pressure hot water, radiators and underfloor heating.
What styles are there?
Tall, squat, round, square, modern, traditional. There is a pellet stove for every home.
How clean are they?
Very low emissions — typically far lower than a modern EcoDesign wood stove.
Do I need to clean it?
Minimally: about a minute daily, the ash pan weekly through the heating season, and the chimney once or twice a year depending on use.
Do I need a chimney?
Yes. We can use an existing one or install a new stainless‑steel system.
Do I need an air vent?
Usually not. Over 90% of our installations use a balanced chimney, similar to a modern boiler flue: fresh air is drawn down the outer layer, pre‑heated, and fed to the combustion chamber.
Do I need a hearth?
Yes — non‑combustible, at least 12mm thick.
Will it overheat the room?
No. Pellet stoves are thermostatically controlled: set the temperature and the stove holds it.
Do they suit passive houses?
Yes. With a balanced chimney and thermostatic control they work beautifully in airtight, low‑energy and Passivhaus‑level homes, with no overheating.

Installation

Balanced flues, done properly

Over 90% of our installations use a balanced chimney system, so most homes need no wall vent at all — fresh air comes down the outer layer of the flue, pre‑heated, straight into the combustion chamber.

We can work with an existing chimney or install a new stainless‑steel system, and every installation is carried out by us from start to finish.

From 1.5kW in a single room to over 20kW running a house.

Tell us the room, the layout and what else you heat with, and we will tell you which of the three fits.
