Customers can review TISIGO’s principal domestic and commercial biomass service areas or contact the company directly to confirm coverage for an individual property or multi-site contract.

Why does a biomass boiler require specialist servicing?

A biomass boiler is considerably more complex than a conventional gas or oil boiler. In addition to producing heat, it must receive and transport fuel, control combustion, manage ash, monitor temperatures and draught, operate pumps and valves, and communicate with other parts of the heating system.

A fault that appears to be caused by one component can originate elsewhere. Repeated ignition failures, for example, may relate to the igniter, fuel quality, feed rate, airflow, draught, sensors, control settings or accumulated deposits.

Professional biomass boiler servicing should therefore extend beyond basic cleaning. A competent service may include inspection of:

The combustion chamber and heat exchanger
Ignition and fuel-feed components
Fans, motors, augers and rotary valves
Lambda, temperature and pressure sensors
Flue condition and combustion performance
Pumps, valves and hydraulic controls
Water quality and inhibitor levels
Safety devices and electrical connections
Ash removal and automatic cleaning mechanisms
Boiler settings, alarms and fault history

This whole-system approach helps identify developing problems before they cause an avoidable breakdown.

Domestic biomass boiler servicing and repairs

Homeowners depend on their boiler for heating and hot water, often in rural properties without access to the gas grid. A breakdown during cold weather can therefore become serious very quickly.

TISIGO provides domestic biomass boiler maintenance for wood-pellet, log and woodchip heating systems. Its engineers carry out system inspections, combustion-area cleaning, sensor testing, fuel-feed checks, performance assessment and repairs where faults are discovered.

Routine maintenance can help to:

Reduce the likelihood of unexpected breakdowns
Maintain efficient combustion and sensible fuel consumption
Identify worn components before complete failure
Improve heating reliability
Extend the useful life of the boiler
Support applicable manufacturer maintenance requirements

TISIGO also provides domestic biomass boiler installation, repairs and upgrades, including support for boilers that the company did not originally install, subject to an initial technical assessment.

Commercial biomass boiler maintenance

Commercial biomass installations frequently serve farms, schools, care facilities, workshops, offices, accommodation sites and other buildings where prolonged heating failure can disrupt normal operations.

TISIGO’s commercial biomass boiler services include planned maintenance, repairs, technical investigation, installation and ongoing service support. The company offers HABMS-approved commercial service contracts for biomass boilers up to 2 MW.

A structured maintenance arrangement can be particularly valuable for commercial operators because it provides:

Planned servicing around operational requirements
Earlier identification of deteriorating components
More consistent maintenance records
Reduced exposure to unplanned downtime
Better preparation for seasonal heating demand
An opportunity to plan repairs and parts procurement
Support with applicable RHI and maintenance obligations

Rather than treating every breakdown as an isolated event, effective commercial maintenance should consider repeated alarms, fuel quality, servicing history, system loading, controls and the performance of the wider heating installation.

Biomass engineering for industrial sites

Industrial biomass boilers may be used to heat factories, warehouses, workshops, recycling facilities and manufacturing premises. Some systems also contribute to process-heating requirements.

These installations can contain multiple boilers, large fuel-storage and conveying systems, complex controls, buffer vessels, heat-metering equipment and extensive distribution networks. Their scale means that minor defects can develop into expensive operational failures if they are not identified promptly.

TISIGO works across a range of commercial and industrial biomass sectors, including:

Agriculture and farming
Manufacturing
Factories and warehouses
Education and public buildings
Recycling and waste management
Garden centres
Care facilities
Large commercial properties

For industrial customers, the objective is not simply to restart the boiler. The underlying cause of a failure must be identified, repairs must be practical, and the effect on the wider plant must be considered.

Biomass boiler fault diagnosis and repair

Effective fault diagnosis is one of the clearest differences between a general heating contractor and an experienced biomass engineer.

TISIGO’s engineers investigate mechanical, electrical, combustion and system-related faults. This may include testing components, reviewing boiler data, inspecting fuel delivery, assessing combustion conditions and establishing whether a failure is the cause of the problem or merely a symptom.

Published customer feedback on TISIGO’s service-area page highlights successful diagnosis of persistent ignition problems, helpful technical advice and the restoration of pellet-heating appliances that were no longer performing correctly.

Where replacement parts are required, access to suitable components can be as important as the diagnosis itself. TISIGO’s associated EcoSpares biomass parts service supplies genuine and specialist components for a range of biomass systems, helping reduce delays caused by difficult-to-source parts.

Biomass boiler installation, replacement and upgrading

TISIGO also designs, installs and commissions biomass heating systems for homes, businesses and larger commercial properties.

A successful installation must be based on more than the nominal boiler output. The design should consider the building’s heat demand, operating pattern, fuel type, fuel storage, delivery arrangements, flue, hydraulic design, controls, buffer capacity and future maintenance access.

For existing systems, complete replacement is not always the only answer. Depending on the boiler’s condition, targeted improvements to controls, metering, fuel feed, hydraulic arrangements or worn ancillary equipment may provide a more proportionate solution.

TISIGO assesses each installation individually and recommends work based on technical need rather than unnecessary replacement.

Which biomass boiler brands does TISIGO support?

Biomass boilers differ significantly between manufacturers. Control logic, service procedures, fault codes and replacement components are rarely interchangeable, making brand-specific experience valuable.

TISIGO works with numerous established biomass heating manufacturers. Its published biomass boiler brands include Woodco, Duroflame, KWB, Trianco and Fröling, with support also available for other domestic, commercial and industrial systems.

Customers should provide the boiler manufacturer, model, approximate output and displayed fault information when making an enquiry. Photographs of the boiler, control screen and affected components can also help the engineering team prepare for the visit.

Heat meter replacements and RHI support

Heat meters play an important role in many non-domestic Renewable Heat Incentive installations. Inaccurate, expired or unsuitable metering can create compliance and payment risks.

TISIGO provides a managed biomass heat meter replacement service, including system assessment, meter identification, safe removal, installation, commissioning and data validation. Relevant documentation can then be retained by the operator for its records and any applicable Ofgem requirements.

Organisations approaching a metering deadline should act before the existing meter falls outside its permitted service or recalibration period. Early planning allows compatibility, availability and installation requirements to be checked without unnecessary urgency.
