Dorchester DRLL water heater meets the requirements of ErP regulations and refurbishment projects alike: It can be used on old systems with existing flues (subject to survey), saving on costs for flue replacements. The integral stainless steel burner produces low NOx emissions (3445 mg/kWh) and benefits from an automatic gas/air premix burning system for increased efficiency. The water heater is available as three models with continuous outputs (50°C delta T) of 850 to 1600 litres/hour, recovery rates from 12 to 23 minutes and a working pressure of up to 8
ZTAG3 is a sleek keypad and proximity reader, designed to provide a compact,
proximity tag or pin code activation, accommodating up to 1,010 key tag holders or pin numbers. Users approach the keypad and enter a four digit code or hold a personal proximity tag within a few inches to activate one of the EZTAG3’s two on board relays which in turn activates an appropriate door release in separate controlled areas. The EZTAG3 supports two separate lock outputs, as well as fail safe and fail secure locks. It comes complete with 10 tags and features a robust housing
with a narrow (45mm x 152mm) footprint allowing installation where space is at a premium. The units are further enhanced with the use of LED operational indicators and an attractive blue backlighting of the keypad. There is also a doorbell option. A new black keypad is also
being introduced for the EZTAG3PRO Kit (pictured), which offers a complete door entry system in one handy and convenient box.

bar help to meet the continuous demands of bigger (taller) buildings. The Dorchester DRXP on the other
hand is a condensing water heater with stainless steel tank available in two models (3850kW input) of 184 litres. With an ErP efficiency of 91% 93% and NOx emissions 53 mg/kWh, it is compliant with the latest ErP regulations that were further restricted in 2018. Thanks to the grade 444 stainless steel tanks, no anodes are required to
protect it from corrosion. This makes it a great choice for soft water areas. As fully roomsealed appliance, it can be sited in small compartmental areas. Flexible flue options mean the water heater can be installed almost anywhere.

New Part M additions for GridPro
S
colmore has expanded its GridPro range of interchangeable mounting plates and modules to include Part M frontplates.
The Part M GridPro Frontplates range offers a
visually contrasting, flexible range of wiring accessories and will join Scolmore’s comprehensive Part M collection, which is a high quality, flexible and modern solution to assisted living requirements. The new GridPro additions comprise 1gang, 2gang, 3 gang and 4gang standard switch plates. A key feature of the GridPro design is that there is
no requirement for a yoke with the 14gang frontplates – the modules are secured to the back of the GridPro frontplates via the screw feature on the modules. The benefit of not having to use a yoke is that it allows installers to use standard back boxes. The Part M range also comprises 1gang, 2gang
and 3gang wide rockers. With ease of visibility in mind, these wide rockers are an ideal choice for assisted living installations and to aid with Part M compliance. Completing the Part M lineup is the locating plug
socket originally which is designed to assist people with impaired vision or poor hand to eye coordination to more easily insert a plug into a socket. The contoured shape of the front plate guides the earth pin into position. For further information contact Scolmore on

Smart sensing from Sontay There is one configurable
digital input and one analogue input by default in each sensor. The digital input can be configured as a volt free contact, which could be used for external occupancy detectors, fan proving switches or even pulse counting input for metering products. The pulse counting format uses contact debounce and is filtered. The analogue input can be configured as an additional thermistor (10K3A1) input or a 0 10Vdc input. Two digital and three
innai is offering FREE audits for all hospitals and medical centres in order to
maximise energy and financial efficiency in the delivery of hot water at the point of use. Maximising efficiencies can lead to fuel savings, alone, of up to 30% on current energy prices as the hot water is heated only when it is used turn the tap off and the energy costs can stop immediately. The audit, in close
cooperation with the site, measures all data concerning use and presents a full and detailed report prepared by CIBSE recognised engineers. This is all free of any charge. Rinnai is the world’s
leading manufacturer of continuous flow hot water systems a range of units that can be manifolded to supply, virtually, limitless temperature accurate water to a site of any size. It also means less space spent on plant rooms and no or little maintenance as all units are proven to be robust with extended working life and warranties to support this. Rinnai’s Sensei N Series water
heating range offers a new and compact design with enhanced combustion that allows for easier and quicker installation and gives high levels of operational performance. All components in the range
are designed and manufactured by Rinnai, and this ensures maximum quality and reliability from the world leader in commercial continuous flow water heating products and systems. The Rinnai Sensei N Series is
also the first ever continuous flow hot water heating unit manufactured with stainless steel heat exchangers to be available in the UK this gives a greatly extended working life. Added to this is the Sensei N Series market leading extended warranties. The advanced burner controls
analogue outputs can also be ordered as an option.

with the Sensei N Series models ensure that all the appliances are well ahead of the NOx requirements set within ErP. The current level of permissible NOx set by ErP is 56 mg/Kwh. The Sensei N Series range have
been thirdparty tested at 28 mg/Kwh making them one of the greenest water heating
appliances available. As the units do not incorporate
storage their ‘green credentials’ are further recognised by BREEAM and score additional credits under the building regulations. In answering the threat of
Legionella proliferation – continuous flow technology is
recognised as heavily reducing the risk of Legionella proliferation when compared to other types of hot water delivery. The main reasons for this are that there is no storage, system turn over is regular and the area for debris is much lower than storage type systems. The industry uptake of Rinnai’s
continuous flow heater systems is proven to be more energy efficient than conventional storage systems and are increasingly the experts’ preferred method of hot water provision. Rinnai units easily cater for any size projects that need high volumes of water at intermittent or any times of day. Rinnai manufactures over
2million water heaters every year and as such is at the forefront of creating unit cost advantages for installers. Competitively priced, the units offer all technological advances and innovations, all at a similar cost to lower specification competitor models. Contact the company direct by
