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. THE Domestic heating design guide has been produced to assist specifiers and designers of ‘wet’ central heating systems for single-family and multiple-occupancy buildings and covers both new and existing dwellings. Wet central heating systems are low-pressure hot water (LPHW) systems for distributing heat throughout a building; they are sometimes called ‘hydronic’ systems. The Guide is also intended for practitioners who want to gain a better understanding of the principles and methods underlying the design process, and it offers a method for reaching agreement with a client as to what is needed and will be provided.

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. The latest articles and guides from NBS subject specialists and construction industry contributors. Underfloor heating :This tends to be the emitter of choice for many self builders and extenders, for the comfort, efficiency and the extra wall space it gives You’ll generally be guided (or told) by your supplier or installer what cylinder to install. The advice would be to do some research and take part in the decision – there is a fairly wide spread in terms of efficiency and price. What Size Boiler Do I Need? The PDF version of the Domestic heating design guide has been corrected to reflect corrections to Table 3.18.

However, the more sophisticated the system the greater the potential for problems, so good design often requires a compromise between what is the ideal solution and what is advisable in terms of operational and maintenance considerations. The design and regulatory requirements for the heat generators themselves. Specific requirements for the installation of gas, solid fuel, wood or biomass, liquid fuel-fired and electrical heating equipment, including fuel storage where applicable, are provided in other publications. Only outline details and the implications of the LPHW system for the heat source are given in this Guide (see section 1.6).

The big decision is whether to go with just a boiler or go down the route of installing a renewable energy system, and if so, whether it will be the sole heat source. 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. 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).Interactive training courses and educational material, to help you get the most from NBS software tools This new 2016 edition of the Guide is the result of work undertaken by the Domestic Building Services Panel of CIBSE. The Panel has recognised that the use of under-floor heating has increased significantly in the UK and Ireland and seen the need for the provision of additional advice on the subject, specfically for those operating in the Domestic Sector. Equipment manufacturers provide comprehensive instructions and training in the design and installation of their own products. However, with the more widespread use of floor heating there is a requirement for a more general level of advice on design and installation procedures. To make a difference to your heating bill, the control system must allow the temperature to be set for each room. It is uncommon that a house will need every room to be heated to the same temperature at the same time (think guest bedrooms which only receive occasional use).
