An oversized boiler short-cycles, wears out and costs more to run. We size from the heat-loss figures for the actual building.

Wall-hung and floor-standing condensing boilers, combi units, burners and complete boiler-room packages.
Wall-hung combi and system condensing boilers for apartments, floor-standing and cascade units for buildings, gas and oil burners, plus the boiler-room hardware around them — manifolds, circulators, expansion vessels, flues and controls. Sized against the real heat load, supplied as one package, documented for the gas certification file.

A boiler only hits its best efficiency when the rest of the system lets it — the emitters, the controls, and how the whole plant is put together matter as much as the badge on the front. We spec the plant so the boiler runs at its best for years, not just on the day the brochure was printed.

A boiler two sizes too big costs more to buy, more to run, and dies sooner. Getting the size right is the cheapest upgrade in the room.
For blocks of flats and hotels, two to four smaller units working together usually beat one big boiler: the plant tracks the actual load, one unit can be serviced without cutting off heating, and it performs just as well on a mild November day as a cold January one.
The boiler, the flue, the pumps and the controls are quoted and delivered as one package, with the documents your gas engineer needs to sign off.

A compact combi boiler covers most flats. Larger families or two bathrooms in daily use call for a system boiler with its own cylinder, so the shower doesn't drop when the kitchen tap runs.

Two to four units working as one plant cover a wide range of demand and keep the building warm during maintenance. Weather-led controls track the actual day instead of a fixed setting.

Radiators, underfloor heating and air-handling coils can all run at their own temperature from one plant, with building-management-ready controls that report on it.

A large hall loses heat fast through doors and roof, so we size the plant and the air handling to the actual volume rather than a nominal floor area, and choose destratification or warm-air units where they beat radiators on running cost.

We pick the output from the actual heat loss, then check how low the boiler can modulate — that's what decides comfort and bills in mild weather.
Correct controls and correctly sized emitters keep the boiler in its most efficient mode, which is where the quoted efficiency actually happens.
Route, length and condensate drainage are resolved before installation day, not improvised on it.
Compliance certificates and flue drawings go straight into your gas certification file — we prepare them as part of the order.
A boiler squeezed into a cupboard with no clearance turns every annual service into a half-day job and every repair into a bigger one. We check access, ventilation and clearances against the actual room before the units are ordered, so maintenance never becomes the excuse for a breakdown.
Insulation and hot-water demand change the right size far more than square metres do.
Without the rest of the system corrected, the promised savings never show up on the bill.
It needs a proper, frost-safe route — get it wrong and it becomes a leak later.

The boiler, the flue, the pumps and the controls are quoted and delivered as one package, with the documents your gas engineer needs to sign off. This is the part most suppliers leave out: what we import, how gas Boilers & Burners should be specified before anyone prices it, where projects lose money, and what our 1–2 weeks lead time actually covers.
Wall-hung combi and system condensing boilers for apartments, floor-standing and cascade units for buildings, gas and oil burners, plus the boiler-room hardware around them — manifolds, circulators, expansion vessels, flues and controls. Sized against the real heat load, supplied as one package, documented for the gas certification file.
Because we buy gas Boilers & Burners directly from the factories, the range you see is the range we can programme — not a catalogue we hope to source later. In practice that means combi Condensing Boilers, system Boilers and floor-Standing & Cascade, each with its own price band and availability, so a specification can be tuned to a budget instead of abandoned.

Specifying gas Boilers & Burners well comes down to a short list of decisions taken in the right order — size to the building, then check turndown, design for a boiler that actually condenses, plan the flue with the boiler and get the paperwork sorted. Taken on paper, these cost nothing. Taken on site, each one is a change order.
We write the specification with you before anything is quoted, so the number you get is for the material that will actually be installed. That means confirmed dimensions and finishes, the right performance class for the space, and quantities that include the waste factor rather than discovering it mid-installation.
The same reference behaves differently depending on where it goes — apartments and houses, apartment blocks and cascades, hotels and guesthouses and offices and clinics each carry their own requirements, and we specify against the space rather than against a mood image.
Recovers extra heat from the flue gases for a real efficiency gain — but only when the system around it is set up right.
One appliance for both heating and instant hot water.
Several boilers run as one system, for wider range and built-in backup.
Automatic control that adjusts the boiler to the outdoor temperature.
Almost every delay we are called in to rescue traces back to the same handful of causes: sizing on floor area alone, fitting a modern boiler to an old system, forgetting the condensate drain and mixing control brands blindly. None of them are exotic, and all of them are avoidable at specification stage.
Sizing on floor area alone is the most expensive one, because insulation and hot-water demand change the right size far more than square metres do.
We have supplied gas Boilers & Burners into apartments, apartment blocks & hotels and offices & clinics, and the pattern is consistent: the projects that run smoothly are the ones where the material was locked before the trades were booked.
Fitting a modern boiler to an old system — checked once on paper, never again on site.
Insulation and hot-water demand change the right size far more than square metres do.
Without the rest of the system corrected, the promised savings never show up on the bill.
It needs a proper, frost-safe route — get it wrong and it becomes a leak later.
Smart modulation only works when the thermostat and boiler are compatible — we make sure they are.
Standard lead time on gas Boilers & Burners is 1–2 weeks from confirmed specification, and that window covers the whole chain — factory programming, consolidation, transport, customs where applicable and delivery to site or to your warehouse. We quote the landed number, not an ex-works price that grows later.
Pricing is per project rather than per line. Because we import directly and consolidate gas Boilers & Burners with the rest of the materials for the same room, you get one quote, one delivery window and one point of contact — and the savings show up on the total, not just on a headline reference.
If you already have drawings, send them and we will come back with a specification and a landed price. If you do not, we will build the specification with you first. Either way, nothing is ordered until the quantities, finishes and dates are agreed in writing.
For most apartments a 24–28 kW wall-hung combi condensing boiler covers heating and instant hot water on a single unit. Larger flats with two bathrooms take a system boiler with a cylinder so hot water doesn't fall away when two taps run.
The equipment price depends on output, modulation and controls — we quote direct importer pricing on the boiler plus the full boiler-room package, so you compare one figure instead of a boiler price plus surprises.
If the building already has a gas connection and radiators at 60–70°C, a condensing boiler is the low-capex answer. If you're building or moving to underfloor heating, a heat pump usually wins on running cost. We quote both against your figures.
Often yes — a modulating gas or dual-fuel burner on a sound boiler body is a fraction of the cost of a full plant replacement. We check the body, the flue and the controls before recommending it.
Yes — declarations of performance, efficiency data, flue schematics and installation manuals come with the equipment, which is what your gas engineer needs to certify the installation.
