The fittings are also threaded 3/4” BSP male should threaded pipe connections be required. Air ducts must be at least in 6 inch rigid pipe. 4.3 COLD WATER SUPPLY A 22mm cold water supply is recommended, however, if a 15mm (1/2”) supply exists which provides sufficient flow (see section 2.3) this may be used.
4 . Installation Hot water air source heat pump 4 . Installation Hot water air source heat pump Should you wish to site the Expansion Valve on the Cold Water Combination Valve this can be done by unscrewing the connection nut beneath the Expansion Valve on the Expansion Core Unit and removing the Expansion Valve. The connecting nut and blanking plug should then be unscrewed from the Cold Water Combination Valve and replaced with the Expansion Valve.

UNVENTED HOT WATER STORAGE SYSTEMS AND CONTROLS The purpose of this guide is to provide useful information on Unvented Hot Water Storage Systems and their benefits, the features and functions of the typical controls used. How the Unvented System Works The basic difference between the high pressure Unvented Systems and a traditional low pressure vented system is that we no longer require the cold water storage cistern, open vent pipe or cold feed pipe.
UNVENTED HOT WATER STORAGE SYSTEMS AND CONTROLS The significant benefits to be gained from the installation of an Unvented Hot Water Storage System can be divided into two categories; benefits to the Specifier/Installer and benefits to the householder. Householder Benefits • Superior performance - ensures constant high flow rates at all outlets and allows rapid filling of baths. • Balanced pressures - far wider choice of continental style taps and showers can be used.
UNVENTED HOT WATER STORAGE SYSTEMS AND CONTROLS A recent development now available in the UK is the Combi Storage unit. This type of unit incorporates the benefits, features and controls associated with Unvented Systems but has a limited storage capacity of hot water. Bubble-Top Units Bubble-Top units, manufactured from either copper or stainless steel, accommodate the expansion of the heated water by using an internal air-bubble which is generated and trapped at the top of the unit during commissioning.
UNVENTED HOT WATER STORAGE SYSTEMS AND CONTROLS Originally supplied as separate components, Reliance have developed and engineered these controls to form a one piece or two piece Inlet Control Group for units requiring DN20 Nominal size controls and, a three piece Inlet Control Group for units requiring DN25 size controls.Inlet Control Group One Piece (Multibloc).
UNVENTED HOT WATER STORAGE SYSTEMS AND CONTROLS Inlet Control Group - Two Piece (Core Unit) Inlet Control Group - Three Piece (Check Valve Manifold) Forerunner of the Multibloc one piece control, this Inlet Control Group is again used on all types of Unvented Systems and comprises of a separate Pressure Reducing Valve/Strainer and combined Check/Expansion Valve core unit offering the following features.
UNVENTED HOT WATER STORAGE SYSTEMS AND CONTROLS All Reliance Inlet Control Groups are supplied with comprehensive Installation and Maintenance instructions to supplement the relevant Unvented System manufacturer‟s Instructions. All potable Expansion Vessels with a nominal capacity of 16 litres or greater incorporate a replaceable membrane to facilitate replacement in the unlikely event of failure.
UNVENTED HOT WATER STORAGE SYSTEMS AND CONTROLS The Temperature & Pressure Relief Valve is the third and final level of protection. Although this valve does incorporate a pressure relief function, the sole purpose of this control is to prevent the system water temperature exceeding 99° C - the pressure relief function is not used.
UNVENTED HOT WATER STORAGE SYSTEMS AND CONTROLS Spare Components Problems and Remedial Action The Inlet Control Groups supplied by Reliance for use with Unvented Systems have proven to be extremely reliable in field service but, in the unlikely event of failure, the following spare components are available from the relevant manufacturer of the Unvented System in question.
TPR15 Pressure and Temperature Relief Valves Appendix 2 Product Specification Sheet TPR15 Pressure and Temperature Relief Valves A compact, cartridge type pressure and temperature safety relief valve for use on unvented hot water systems. Uses Product Features and Benefits • Fully approved by WRAS for use on unvented hot water systems. • Available in a wide range of relief pressures between 4.0 and 10 bar.
TPR15 Pressure and Temperature Relief Valves Description The new Reliance compact pressure and temperature relief valve has been designed to provide protection against over pressurisation which can occur within an unvented hot water system if the input temperature controls fail. The valve is designed to be fitted in the upper portion of the cylinder as this is where the hottest system temperatures will be found.
