Biomass Boilers

Biomass boilers provide automatic heating systems using renewable sustainable fuel.

Pellets are made from wood in small standardised cylindrical pieces. No adhesives or additives are used.

As with lump wood, combustion is carbon neutral and this represents a considerable contribution to climate protection.

Chip/Pellet boilers also available –individual outputs to 300kW.

Fuel Feed Systems supplied for chip and pellet systems – selection below - other designs available

Evacuated Tube Solar Panels

Full vacuum tube collectors

The full vacuum production technique produces high performance, even in winter. The fast reaction collectors ensure a better gain than with flat panel, partial vacuum collectors and in poor weather (lowradiation) conditions. Protected against hail and storms. In combination with the stable base,theplacement of the tubes with air slots between them provides low wind resistance, and the thickborosilicate glass construction in combination with the rounded tube surface diverts the hailavoiding damage,

High annual efficiency Excellent winter performanceQuick kick off Highly efficient vacuum insulationLong life

Thermal Solar Panels Sunstar 1670 & 2470 (Heat Tube)

Each panel comprises 16 or 24 tubes, Multiple panels are used to increase heat output.

When installed the angle of the panels may be adjusted to optimise

seasonal performance.

Thermal Solar Panels Sunstar DF 100-6 (Direct Flow)

Each panel comprises 6 tubes, Multiple panels are installed to increase heat output.

These panels may be

installed vertically or flat.The image above shows aninstallation where thepanels are installed at anangle of approximately 87.5o.

Proven reliability Tubes have overheat protection No sun damage when not in use Hail resistant borosilicate glassWork even in cloudy weather

Radiator Free Standing

Range Radiator

The Olymp aluminium radiators transmit heat 4 times faster than steel. Their low water content leads to further savings. Compared to steel radiators, savings of up to 30% may be achieved.

This also means that an Olymp AluRad will be smaller and considerably lighter than a steel radiator with the same heat output at the same flow temperature.

AluRads are smaller and ideal for heat pumps and systems with under floor heating without performance loss.

MHIV Water Booster Set. Single pump booster set featuring a high

efficiency Lowara variable speed multistage pump. By utilizing variable speed technology this booster set will reduce power

consumption, energy costs and noise levels. The booster set size is also reduced as the design requires expansion vessel to store a smaller volume of buffer liquid than usual.

High quality buffer vessels from copper, mild steel, stainless steel and galvanised mild steel materials. Our buffer vessels can be connected to many different types of systems ranging from air conditioning chillers, biomass boilers, heat pump boilers, solar thermal or a

combination of these. Our vesselsrange from 10 litre all the way up to10,000 litres meaning we can caterfor any building from a small canalboat to a large office block, school or hospital.
