Chapter 10 Domestic fuel systems

                6 CONSIDERATIONS THAT

                COULD AFFECT THE STORAGE

                REQUIREMENTS OF FUELS


                When considering the type of fuel system to be used in a dwelling, there are
                several factors that need special consideration:
                l  space for fuel storage
                l  delivery requirements
                l  safety
                l  weather conditions
                l  distribution
                l  proximity to dwelling.

                Space for fuel storage
                Space for fuel storage is a major factor when deciding which fuel system to use.
                Most fuels require specific distances in which to site storage vessels, tanks or
                silos. This may take the form of environmental concerns, as with heating oil, or
                explosion or fire risks, as with LPG. Where biomass is concerned, it may be the
                sheer mass of the fuel that is problematic.

                Delivery requirements
                The transportation and delivery requirements for domestic fuels differ
                according to the fuel, as described below.
                l  Heating oil: most oil tankers carrying domestic heating oil carry 45 m of
                   hose. This is suitable for most installations. However, extra-long hoses can be
                   requested. Consumers should remember to measure around any corners or
                   obstacles when stipulating the oil tank distance from the access point.
                l  LPG: LPG bulk deliveries are usually delivered in mini-LPG tankers. These
                   are 2.6 m wide and require access 2.75 m wide with a minimum access road
                   width of at least 3 m. It is a requirement that a line of sight is maintained
                   between the storage vessel and the tanker, with a maximum hose length of
                   40 m, to ensure the safe delivery of LPG to the bulk storage tank.
                l  Coal/smokeless fuels: solid fuels such as coal and smokeless fuels are   p  Figure 10.16 A typical small

                l  Biomass: in October 2015, rules to support sustainable fuels for the       deliveries
                   Domestic Renewable Heat Initiative (RHI) came into effect for all biomass
                   heating systems. The Domestic RHI scheme aims to support homeowners
                   and landlords who have invested in renewable heating technologies. This
                   includes biomass, heat pumps and solar thermal panels. The idea behind the
                   RHI scheme is to reward those people that stick to the RHI rules regarding
                   sustainable supplies of fuel by paying them a tariff per kW/h. Payments are
                   made every three months for a period of seven years.
