Central Heating: A Design and Installation Manual

Product Information

Typical boiler requirements for a larger detached house would be in the region of 30kW. Heating System Jargon Buster

Combi boilersare the only option that do not require a hot water store. That apart, there are a number of other reasons for choosing another option (which include a hot water store) — not least, the increased efficiency of all the other options and that combi boilers preclude the use of any form of renewable energy. A comprehensive online collection of construction related standards, regulations, technical advice and articles The Domestic heating design guide is published by the Domestic Building Services Panel ( www.dbsp.co.uk ), a joint initiative of the heating industry and the Chartered Institution of Building Services Engineers. Interactive training courses and educational material, to help you get the most from NBS software tools To aid in the design and specification of LPHW space- and water-heating systems connected to an automatically controlled heat source. This includes open-vented and unvented/sealed heating and domestic hot water heating systems.Boilers come in different sizes (measured in kW) and you need to specify the right one — a boiler that’s too large will not only be more expensive but will operate less efficiently than an adequately sized model. Modern central heating systems have to be capable of meeting the user’s expectations of providing an adequate level of heating in an efficient manner. An efficient system is one that provides the correct amount of heat at the correct place and the correct time, burning the fuel used in the most efficient way possible, switching off the boiler when the demand is satisfied. Achieving this objective will require correct system design, avoiding inefficient oversizing of plant, and the use of appropriate controls. this initial burst of enthusiasm lead to him trying (and failing) to build a biogas digester to convert pig manure into fuel, at a Kent oast-house, his first conversion project.

His interest in renewable energy and sustainability was first inspired by visits to the Royal Festival Hall heat pump and the Edmonton heat-from-waste projects. In 1979 A gas boiler supplemented by solar thermal panels or an air source heat pumpare becoming increasingly popular options thanks in part to increases in the Renewable Heat Incentive (RHI — the government’s scheme to incentivise the take-up of renewable heat-generating technology). The storage vessel which supplies hot water on demand to taps and showers, located in the airing cupboard. Depending on the type of system, it either heats up cold water supplied by the cold water storage tank, stores hot water supplied directly by the boiler, or heats up cold water supplied directly from the mains. Tim is an expert in sustainable building methods and energy efficiency in residential homes and writes on the subject for magazines and national newspapers. He is the author of The Sustainable Building Bible, Simply Sustainable Homes and Anaerobic Digestion - Making Biogas - Making Energy: The Earthscan Expert Guide.

Mains gas (when available) is the cheapest fossil fuel option in terms of installation, capital and running costs. Renewable energy systems still have a relatively high capital cost but their low running cost make them the better long-term option.
