Biomass Systems

CHP Mechanical Services take great pride in the knowledge that all products used in our installations are of the highest quality hence the choice of the manufacturer Herz which offers a range of boilers to cover both the domestic and commercial markets. The Herz range utilises the latest in Austrian technology and has been continuously active in the market since 1896. The company is proud of its focus on “modern, cost-efficient and environmentally friendly heating systems with the highest levels of comfort and convenience as well as being user friendly.” By selecting a Herz system customers are achieving a balance between quality, cost and sophistication.

Biomass systems (or Wood Pellet/Wood Chip Boiler) can reduce your heating bills by up to 40% against gas and oil. They are an economical way of heating your home with efficiency in excess of 90%. The boiler is a fully modulating boiler which burns wood pellets. The pellets are normally delivered in bulk and blown in to your pellet store, they are then transferred by an auger to the boiler.

The boiler operates on a time clock just the same as your oil or gas boiler, so you do not need to do anything more than you do with oil or gas with the exception of emptying the ash pan every 4 – 5 weeks, although de-ashing is available on all our boilers at an additional cost.

For Domestic Installations: some of the considerations you must make when purchasing a wood pellet boiler are:

•Have I got space for a 2.4m2 pellet store beside the proposed boiler location?
•Will the pellet delivery lorry get within 15m of my pellet store?
•Is the entrance to my property large enough to allow the pellet delivery lorry access? (Typical size of an oil tanker).

 

Benefits of a wood pellet boiler include:

•Carbon neutral
•Reduce heating bills by up to 40%
•Grant aid available pending Renewable Heat Incentive
•More stable fuel prices than oil or gas
•Fully modulating boiler

Wood Pellet/Wood Chip Boiler (54– 500 kW)

BioMatic boilers are one of the most compact biomass systems available on the market and have the smallest carry-in dimensions of equivalent systems. All six models in the range have a compact modular design allowing for fast installation, and in most cases, the boiler can be installed into existing oil or gas plant rooms. BioMatic systems are automatically cleaned during. Operation is controlled automatically with BioControl 3000, providing ease of use. Combustion and emissions can be optimised and controlled using the installed Lambda Probe which continuously monitors exhausts and fuel qualities. Installations can be tailored to individual needs with a range of solutions for large buildings such as hospitals and hotels, as well as housing estate projects and wood-manufacturing plants.
