Whitfield House, a magnificent stately home nestling in the Herefordshire countryside, is being economical on its heating bills and making use of the acres of managed woodland that surrounds it; a saving provided by a wood-chip burning heating system from Euroheat.
St Peter’s Church in Peterchurch, Herefordshire, has recently been adapted to bring 12th and 21st century architecture together. Recent renovations have included under floor heating, making this once draughty building warm, powered by a Compact HDG 65kw pellet boiler supplied by Euroheat.
HDG Compact 50 Wood Chip and Wood Pellet water heating Boiler
What is special about HDG Compact 50kW
Overview
Especially Clean
The advanced combustion technology of the Compact is perfectly designed to burn pellets or wood chips as fuel, resulting in very low emission values. Extremely high efficiency levels are also achieved through the combustion of this environmentally friendly fuel.
Especially Econmical
Optimitsed combustion technology results in low pellet comsumption. An advanced thermostat controls the boiler temperture ensuring that only the required amount of heat is produced.
Absolutely Safe
The HDG compact has been subjected to strict in-house and independant safety tests. The cellular wheel sluice reliably prevents back-burn and the escape of low temperture gas. This sluice wheel, combined with an integrated water extinguishing system provides total safety.
Especially Convenient
Features such as automatic transport of the pellets to the combustion chamber, automatic ignition, self activated cleaning and large ash container combine to provide maximum convenience automatically controlled by the HDG Comptronic boiler control.
The HDG Compact 50kW at a glance:
The HDG Compact 50/65 is an automatic wood-heating system which is designed to burn wood chips, pellets and shavings (up to 45% wood moisture content, wood chips up to 50 mm 2 cross section, maximum length 120 mm).
It offers convincing features such as innovative HDG Compatronic burning and control technology, a rotary feeder for uncompromised safety, automatic cleaning and ash removal for maximum convenience as well as economical operation.
The compact and economical heating boiler is delivered completely assembled. Upon request, it can also be supplemented with reliable remote maintenance and SMS control functions.
How it works
Fuel is fed directly onto the combustion grate. Fuel feeding, primary and secondary air are controlled independently of one another. Tilting grate technology ensures that optimum performance is maintained even when the proportion of non-combustible material is increased.
The system only operates with combustion emissions at an optimum level. Prolonged smouldering is avoided while glowing hot embers are maintained. This serves to counteract the contamination of the heat exchanger and the chimney.
When the fuel reaches the fill level, it is ignited by hot air blowers. The automatic ignition feature makes the system even more convenient to operate and enables automatic operation with minimal effort from the user.

The cleaning turbulators make the cleaning of the heat exchanger significantly easier. Upon demand, they can be moved automatically by means of a drive unit.
The tilting grate dumps the ashes into the ash container below. Ash and non combustible material are completely removed, thus ensuring consistent maximum output from the boiler. This concept also allows for the use of logs during emergency operation.
As an option, ash in the combustion chamber and flue ways can be conveyed by means of ash removal worms into outdoor ash containers, which are fastened to the boiler body with quick release clamps. The mobile containers are disconnected from the boiler in one simple step, so that they can be completely and easily emptied.
Heat conveniently. With wood! This is what we`re working steadily and intensively toward. Wood heating with HDG boilers is thus not only ecological and economical but at the same time dependable and user-friendly.
Standing behind our products are more than 180 committed employees as well as numerous factory representatives and heating engineers in Germany and the UK, who support our customers on-site.

Typical quality by HDG Our home and company philosophy Standing behind the HDG name and brand is a management team and over 180 employees who do their jobs with conviction and conscientiousness.
HDG is assisting in the change in energy provision. The high demand for wood heating systems is evidence of the dynamic increase in the importance of wood as a fuel for heating and shows that HDG heating systems are a solution of interest and are desired as products.
Experience brings trust
Innovators in the field of wood heating
Development and production
In the wood market segment, HDG has an extensive product range such as is scarcely offered by any other supplier; it comprises boilers for heating with log wood, sawdust, wood chips and pellets. The spectrum of off erings extends from modest heating systems of 4.5 kW to large systems of 400 kW. This wide variety reflects the established professional experience of the company. HDG has thus won the trust of buyers in agriculture and forestry, in commercial enterprises as well as private users. The total of over 35,000 satisfied customers speaks for itself.
HDG has long spurred the development of wood heating systems forward. In addition to the optimisation of combustion technology, the team of developers also focuses very heavily on the improvement of user-oriented features. The consistency with which this is implemented is evidenced by the many awards for innovation that HDG has received. These confirm how important the developments by HDG are for the advancement of heating technology.
HDG develops and designs its own products and produces them with a high standard of manufacturing quality. Qualit is the keyword in all levels of the production process. Quality assurance is initiated as early as the designing stage of products. They are supported at all levels of production with a differentiated quality management system and the final assembly also serves as a quality check. Furthermore, independent testing institutes are charged with performing regular inspections of the products according to the strictest standards of quality.
Typical quality by HDG User-friendliness, cost-eff ectiveness and environmental protection are the three large criteria at HDG. Our heating systems are designed to make heating with wood convenient for our customers. The operation of the system – whether during heating up, refi lling or the system’s care and maintenance – should therefore be as simple and convenient as possible. A high degree of effi ciency, but also high durability in regard to the demands of use as well as an above-average service life and very low emissions are the characteristics shared by HDG heating systems.
