Who are Domusa?

Domusa Teknik are the market leading boiler manufacturer in Spain with 30% market share of their general boiler market and over 50% of the pellet boiler market. They are known for producing well priced, high quality appliances without compromising on innovation.


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 an efficiency rating greater than 93%, this boiler performs as well or better than other appliances that are twice the price.

Fully certified for the UK

The Bioclass HM has full MCS accreditation, is RHI compliant, and has Clean Air Exemption.


Updated burner design

Solid fuel produces ash and poor quality fuel produces klinker and residues that negatively affect the performance of your boiler.¬† The Bioclass HM is the third generation of pellet boiler with a highly optimised grate design crafted with the experience of 1000’s of running systems. As with all Domusa boilers, the burner is removable, and easy to clean and service.

Fully Modulating

The Bioclass HM 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 HM can also 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 separate 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 separate 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 HM comes in power outputs of 10, 16, 25, 43, and 70kW which will cover most UK domestic and smaller commercial applications. For larger outputs the boilers can easily be cascaded using a single hopper, giving a total of up to 140kW.
