Who are Domusa?BioClass NG

Domusa are the market leader boiler manufacturer in Spain with the 30% market share of their general boiler market and a 50% of the pellet boiler market. They are known for producing well priced, high quality appliances without compromising on innovation. The Biomass NG boiler is their latest generation pellet unit, with new controls, a patented grate cleaning system, and an innovative return water pre-heat. This dispenses the need for specialist valve sets normally required for biomass appliances.



EN 303-5 Class 5 Certification

Domusa have tested their appliance and it has achieved the best classification in the latest EN303-5 standards. With a 95% efficiency rating, this boiler puts many of the premium Austrian boilers to shame at less than half the price.

Fully certified for the UK

The Bioclass NG has full MCS accreditation, is RHI compliant, and has clean air exemption.

Automatic CleaningBurner

Solid fuel produces ash, and poor quality fuel produces klinker and residues that negatively affect the performance of your boiler. The Bioclass NG has a fully automatic heat exchanger and a patented grate cleaning system. The grate cleaner is particularly innovative and is designed for use in markets that burn alternative fuels such as olive stones. It cleans during the operation of the boiler with no performance overhead, so the Bioclass NG can burn 24/7, with no down time.


Fully Modulating

The bioclass NG is fully modulating, this means that it can operate at high efficiency over a wide output band. Typically the boilers will operate at 25% of their maximum power without loss of efficiency. The Bioclass NG can operate with direct connection into the heating system without the need for a buffer.

SiloFlexible Storage Solutions

Bioclass boilers come with a complete set of accessories, from integrated hoppers to bulk fill silos with vacuum feed control. The boilers can also be controlled via an external thermostat, or even using telephone control as standard.



Easy to Install and Service

Domusa have really paid a lot of attention to the ease of installation and servicing. The control systems come pre-configured with control of a Y-Plan system as standard, and have two seperate flow connections for the straightforward control of a hot water cylinder and/or heating system. The simple to use cpu has a neatly integrated display and can control up to two seperate heating circuits if required. Servicing the boiler is done from the front or the top meaning that the boiler can be fitted tight up against the wall. During operation, the boiler is virtually silent meaning that the boiler is ideal for utility room applications.

Large Model Range

The Bioclass NG comes in power outputs of 10, 15.6, 25.3,  and 42.7kW which will cover most UK domestic applications. For larger outputs the boilers can easily be cascaded using a single hopper, giving a total of up to 85.4kW.
