Regulations and guidelinesThe following regulations and guidelines must be observed:- Hoval technical information and installation instructions- Relevant British Standards and Guidelines- Hydraulic and technical control regulations- Local Building regulations

Water qualityHeating water:European standard BSEN 14868:2005 and VDI guideline 2035 must be observed. Particular note must be taken of the following regulations:

- Hoval boilers and water heaters are suitable for heating systems without significant oxy-genation (system type 1 in accordance below with BSEN 14686:2005)

- Systems with- Continuous oxygenation (e.g. floor heating without diffusion-proof plastic pipes) or - Intermittent oxygenation (e.g. frequent top-ping up required) must be fitted with a system separator.

- Treated heating water must be checked at least once per year or more frequently as specified by the inhibitor manufacturer.

- If, in the case of existing systems (e.g. boiler replacement), the water quality of the existing heating water complies with VDI 2035, it is not recommended that the system be refilled. VDI 2035 also applies to top-up water.

- Before filling new systems, or, if applicable, existing systems, the heating system must be professionally cleaned and flushed before the boiler is filled.

- Components of the boiler/ heat exchanger that come into contact with the water are made of ferrous materials and stainless steel.

- The combined chloride, nitrate and sulphate content of the heating water must not exceed a total of 50mg/l.

- Once the heating has been in operation for 6-12 weeks, the pH value of the heating water should be between 8.3 and 9.5.

Water for filling and topping up the system:- Untreated drinking water is generally most suitable for filling and topping up a system with a Hoval boiler. However, the water quality of the untreated drinking water must always comply with VDI 2035 or must be demineralised and/or treated with inhibitors. The specifications of BSEN 14868: 2005 must be observed.

- In order to maintain the boiler’s high efficien-cy level and to avoid overheating of the heating surfaces, the values in the table below must not be exceeded. These values are calculated in relation to the boiler output (the smallest individual boiler in the case of multiple boiler systems) and the water content of the system.

- The total quantity of water used to fill and top up the system during the boiler’s life must not exceed a value equivalent to three times the water content of the system.

Heating System- The boilers must not be installed in areas where halogen compounds occur and could enter the combustible air (e.g. washing, drying, workshop areas, hairdressing salons etc.).

- Halogen compounds can be caused by cleaning, degreasing, and solvent agents, adhesives and bleaching liquids.

- A suitable supply of combustion air must be guaranteed. It must not be possible to close the air supply apertures. Minimum free area for the air supply aperture is 13cm2 per 1kW boiler output at a flow of 4.2m3/hr. per 1kW boiler output.

- High and low level ventilation should be pro-vided (⅓ high level and ⅔ low level split).

Space requirementsSee separate dimensional information on pages 7 and 8.

Use of Buffer VesselThe BioLyt Wood Pellet boiler is designed to be fully automatic and is supplied with an auto-matic firing device or ignition sequence that will bring the boiler on from cold without manual intervention and has a timed automatic burnout

once the boiler has satisfied its set point temperature returning the boiler to an “out” condition. From cold the boiler would typically reach its modulating mode after approximately 20 minutes and similarly it takes approximately 20 minutes for the burnout to bring the boiler from the modulating mode to out. Once the burnout process is initiated it has to take the boiler out. It is therefore strongly recommend-ed that a load balancing buffer or accumulator vessel is included in the primary boiler circuit to ensure that any sudden or variable system requirements can be met promptly. Please contact Hoval Technical Department for advice on sizing.

Heating InstallationLow return temperature protectionA boiler low return temperature protection kit is supplied with all BioLyt boilers to ensure that the minimum return temperature requirement of 45°C is met. Details of this kit are shown on page 18 of this leaflet and also shown on the typical hydraulic schematics.

Hydraulic system DesignThe boiler hydraulic system design must comply with an official Hoval schematic. Vari-ous examples are included in this leaflet and a range of schematics can be downloaded from www.hoval.co.uk, or can be supplied on request. Please contact Hoval Technical for further advice.

Noise AttenuationThe following steps can be taken to reduce noise:- Make the walls, ceiling and floor of the boiler plant room is as solid as possible, fit sound absorbers in the air supply ducting, provide conduit supports and brackets with sound dampening fittings.- If there are living quarters either above or below the boiler plant room, fit rubber vibration dampers underneath the base channels of the boilers and connect pipework with flexible connections.- Connect circulating pumps to the system with flexible connections.

Expansion vessel/ expansion- It is recommended that the system expan-sion vessel is connected to the heating system with a cold fill loop. This means that the entire system will not need to be emptied in order to carry out work on the vessel.- In the case of open vented, the system height must be such that the required minimum oper-ating pressure is maintained.

Safety valve & automatic air vent- A safety valve and automatic air vent must be fitted to all boilers.- A Hoval safety valve and automatic air vent set (c/w pressure gauge) is included with the boiler as an accessory. Please see page 17

■Wood Pellet store design and feeding system guidelines

11 42125186/00 - 08/16

Hoval BioLyt (50-160)

The successful and effective biomass installation in depend-ant on a well-planned and installed pellet feeding system to ensure the delivery of pellets to the point of combustion in the correct volume, quantity and quality.

With regard to the bulk storage or wood pellet fuel store the following simple guidelines offer advice to assist in the design and sizing for a successful installation.

A bulk wood pellet store should be located as close as pos-sible to the biomass boiler. The design of the fuel store and the recovery of the pellets from the store to the subsequent transfer of the fuel to the boiler should be kept as simple as possible. Tall thin storage, such as purpose designed silos, often represent the most effective way of storing wood pellet fuel and can lead to the best use of given storage volume. The angle of the discharge cone from such a silo would typically be 60° to ensure complete mass flow from the store. A possible alternative to a storage silo would be a bespoke build bunker store. These typically require a larger floor area and are less effective in terms of the available recoverable volume of fuel. Some profiling of the bunker base should be considered - minimum angles of 45° should be adopted if profiling a bunker - which will significantly reduce the volume available for the storage of pellet fuel. The natural angle of repose of the fuel will vary depending on the quality of the wood pellet but will typically be greater than 45°. Again this can significantly reduce the recoverable volume available in the pellet store. Whichever fuel store design is adopted it must be such that it:

- Keeps the fuel dry as water ingress will cause the pellets to fall apart and block handling equipment.- Is located as close as possible to the boiler.- Has adequate vehicle access to allow easy bulk delivery.- Is fitted with appropriately sized delivery pipe work.- Bulk fuel deliveries would normally blow fuel into a store via a delivery pipe.- Delivery pipe work/bunker design should not cause undue fuel breakage during delivery.- Is sealed to prevent possible dust nuisance.- Conveying air used for fuel delivery needs to be filtered prior to discharge.- Is sized to suit boiler load and likely bulk delivery pay load.- May need to be behind a fire rated wall if inside the plant room (check with Building Control).

Pellet recovery from the fuel store would typically either be via pick-up auger(s) angled into the bunker or directly from the outlet of a coned purpose built store or silo. From the bunker or silo the wood pellet fuel is delivered to the trans-fer box of the stoker.

There are three key factors that influence the size of the pellet store:

- Available Space - usually adjacent to or close to boilers- Taking account of best use of that space.- Estimated fuel consumption.- The required frequency of delivery - or the size of delivery anticipated.

Hoval can offer a number of silo based fuel store options or advise on most appropriate use of available space for a bespoke build fuel store.
