Typical examples include larger homes and small hotels. Light commercial/non-domestic Ideal for light commercial or non-domestic applications with: • High demands for DHW – e.g. multiple sinks, showers etc. • No or little requirement for space heating – e.g. due to air conditioning, district heating etc. • Where pre-heating of DHW is available. Typical applications include restaurant kitchens, gyms, nurseries, hairdressers, hotels, nursing homes and smaller schools. For more information on ErP, see pages 10-11. Commercial Suitable for large commercial applications where there is: • Consistent high demands for DHW – e.g. laundries, Energy saving condensing design The use of a condensing appliance contributes to achieving higher efficiency by incorporating a secondary heat hospitals, etc. • Very high cyclic demands for DHW – e.g. hotels, schools etc. exchanger. Heat within the flue gases is used to preheat the inlet water, and so recaptures energy that would Greenspring’s ability to use water pre-heated by otherwise be lost. renewable heat sources supports planning and investment requirements. Applications The Greenspring water heater has been optimised for use in Such applications can take full advantage of the cascade domestic and commercial applications where there are high controls that are part of the Greenspring offering. These demands for domestic hot water (DHW). controls provide the ability to deliver up to 250 litres of hot water a minute, on demand, with no need for costly At 50kW heating output, the Greenspring water heater hot water storage capacity. offers the following performance: • Up to 20.6 litres per minute with 35ºC rise • Up to 28.8 litres per minute with 25ºC rise. Certain commercial applications may also take advantage of the ability to provide a hot water temperature of up to 84°C for sterilisation processes and secondary circulation. The Greenspring water heater can be used with natural gas or liquid propane gas (LPG) and can be installed in single units or multiple cascades of up to 12 units. Extended flue lengths of up to 8m are also possible, helping to provide even greater design flexibility. 6 Key beneﬁts to the end user Ease of installation and maintenance High volumes of hot water • Error codes clearly displayed on LCD screen • Front mounted controls • Wall mounted • Easy access to components • Compact design. • Multiple showers, sinks and baths at the same time.

Use with renewables A Greenspring water heater is designed to work with pre-heated water from, for example, a solar thermal system or heat pump(s). If the inlet water is within 5ºC of the set-point on the LCD, the appliance will not fire up, simply letting the pre-heated hot water flow through to the outlets. In this case the solar symbol appears on the LCD (see below). The burner will only fire when it can raise the water temperature by over 5ºC at minimum output. The maximum inlet temperature to the water heater is 60ºC. Cascade kit The cascade kit is a wiring accessory that allows the control of up to 12 water heaters to be connected together for an ‘intelligent’ (rotating lead) cascade.

The ErP Directive, which is a new regulation set by the European Union, is designed to drive improvements in the efficiency and performance of heating and hot water products. Its purpose is to ensure that end users are aware of the level of energy efficiency inherent within their appliances. As such, the Directive will help improve the overall efficiency of the housing stock, while helping homeowners to reduce their energy bills. The ErP regulations cover boilers, combination boilers, water heaters and other heating appliances up to 400kW. What is Energy Labelling? The Energy Labelling involves a label which we are familiar with today on washing machines and televisions at the point of XXL sale. The Energy Labelling regulations introduce Europe-wide energy labelling requirements for boilers, combination boilers, water heaters and other heating products up to 70kW and hot water cylinders under 500 litres. How will the labelling scheme work? The new Energy Labelling Directive will Model name Product A CH efficiency band A A B C D E F G Sound power level kWh/annum GJ/annum dB introduce new efficiency classes with from A to G alongside the existing efficiency 2015 ratings for products in the domestic and light commercial sectors. Most condensing water heaters will fall within the A band, which requires them to achieve more than 85% hot water efficiency (at XXL load profile), while renewable technologies such as heat pumps will likely be in the A+ or A++ bands (depending on flow temperature). 10 812/2013 Annual power and fuel consumption What about systems that contain What if I cascade the Greenspring Continuous different products? Flow Water Heater? In these circumstances, there is a responsibility for There is no requirement to create a package label providing a package label when combining a heating when cascading multiple water heaters. appliance with a temperature control and/or solar device, cylinder or a supplementary heating However, a package label is required when appliance (for example, a two boiler cascade). combining a continuous flow water heater with solar thermal. The person who puts that package together will need to produce a package document known as a fiche (data table) and label that provides the combined energy efficiency rating rather than ratings of each individual component. For example, this could be the merchant’s responsibility if they supply a complete package under one part number or the installer if the items are bought individually under separate part numbers. In this circumstance, Worcester will provide an online tool that makes calculating the overall package efficiency of a Worcester system effortless. ErP easy as ABC with Worcester The Energy Related Products (ErP) Directive comes into force on the 26th September 2015. Worcester will have a number of measures in place to support you including: An online tool which creates product and heating system labels ErP will be covered in all Worcester training courses ErP experts – our technical and customer support teams can answer all your questions.

However, if the appliance is to be fitted in a timber frame building the guidelines laid down in BS 5440:Part 1 and the IGE “Gas Installations in Timber Frame Buildings” should be adhered to. 1. The room in which the appliance is installed does not require a purpose provided air vent. 2. If the appliance is installed in a cupboard or compartment with dimensions that allow the following The appliance must not be installed in locations where the minimum clearances, then no ventilation is required ambient temperature is expected to drop below 0 degrees. (see below): The appliances may be installed into an airing cupboard if required.

See section “Compartment Installation” on right. 20mm* Mounting on a combustible surface All Greenspring wall mounted water heaters can be sited on a combustible surface. EN482, Section 184.108.40.206 states no means for protection of combustible surfaces are necessary if the temperature of the wall does not exceed the room temperature by more than 60ºC. Testing of Greenspring gas-fired wall mounted water heaters has shown that this temperature is not exceeded. Installation and service clearances The minimum clearances shown opposite (fig 1) should be allowed for installation and servicing. Compartment ventilation would be required at these clearances. 14 10mm 10mm Fig 1 Minimum of 20mm required from/for front clearance *To a removable surface Important: bathroom locations and clearances Casing dimensions as illustrated in the diagram below 452mm • The water heater must not be installed in zones 0, 1 or 2 • Any switch or appliance control using mains electricity 286mm C must not be within reach of a person using the bath or shower • Electrical switches, fused spurs and socket outlets must not be situated in the bathroom • A water heater fitted with a non-mechanical timer or with no timer in the water heater can be installed in Zone 2 or 775mm outside the shaded area A • A water heater with a mechanical timer or RF mechanical timer with a room thermostat must only installed outside the shaded area • Additional Residual Current Device (RCD) protection may be required.
