KESTON C40 CONDENSING BOILER THE POWERHOUSE CONDENSING BOILER UP TO 40KW FOR LARGE DOMESTIC APPLICATIONS For larger domestic or smaller commercial applications the C40 delivers a massive 40kW output from a domestic size wall-hung unit with ultra small flueing to match. The C40, as with all Keston boilers, has an extremely high efficiency performance of up to 98% (GCV). The C40 also offers "dual thermostat" technology as standard. This enables the boiler to switch between two temperature settings, depending on the demand source. Ideal for underfloor and hot water applications. For higher output applications Keston offers a complete range of commercial heating products including made-to-order multiple boiler solutions. PRODUCT DESCRIPTIONS A modulating shunt pump, integral to the appliance, will ensure the heat exchanger receives the correct water flow when firing and operates at optimum efficiency. Keston boilers are of low mass and low water content giving a rapid response when there is a call for heat. The unit is totally room-sealed and requires no ventilation for the compartment in which it is installed. As with all Keston boilers, the C40 boiler is exceptionally easy to install and maintain. They are entirely eco-friendly with negligible NOx emissions (Class 5 rated) and can substantially reduce fuel bills.

The design, with its single pass heat exchanger, avoids the complications associated with other condensing boilers. The unit is totally room sealed and requires no ventilation for combustion air to the room or compartment in which it is installed. The C55 is exceptionally easy to install and maintain. Pre-fabricated multiple boiler assemblies are available as an option to assist speedy installation. They are environmentally sound and can save 30 per cent on heating bills. The Keston C55 comprises high efficiency, single pass stainless steel heat exchangers with ultra low emission burners.

KESTON C90 Condensing Boiler The patented design of the wall-mounted C90 is fully modulating from 22kW to 90kW and boasts all the benefits of Keston's condensing technology. The C90 has been developed as an economic solution, both in terms of price and space. The C90 comprises high-efficiency, single pass stainless steel heat exchangers with ultra low emission burners. The boiler can deliver two different flow temperatures at the same time, whilst maintaining low temperature heating output for underfloor or weather-compensated heating. As well as providing perfect operating conditions for such applications, this feature helps saves on pipework and controls, normally required on such systems. The stainless steel heat exchangers are highly corrosion resistant in a corrugated pipe form, which provides massive surface area within a compact dimension. The hot combustion gases from the down-firing pipe burner pass around the pipes imparting heat into the system water. The integral variable speed pumps within the appliance cabinet ensure the heat exchangers receive correct water flow when firing. FEATURES & BENEFITS Easy installation - wall mounted, ultra compact For weather compensation just add an optional sensor Automatic speed controlled pumps for increased efficiency Low cost 100mm diameter plastic flue saves on installation cost No need for mixing or controlling valves Dual flow technology enables the boiler to produce two different flow temperatures at the same time Wall mounted Integral pump exercise function Optional interface box can receive an external 0-10 volt signal to set boiler module temperature Automatic Lookout avoidance - the boiler can anticipate problems in advance Suitable for open vented or sealed systems Keston Brochure PDF	KESTON C110 Condensing Boiler The C110 is wall-mounted and fully modulating, from 28kW to 110kW. As with all Keston boilers, it has an extremely high efficiency performance of up to 98 per cent (GCV). The C110 has been developed as an economic heating solution, with dual-flow technology. The unit is highly energy-efficient, high performance and low on emission burn. The dual-flow technology means that the boiler can deliver two different flow temperatures at the same time, whilst maintaining low temperature heating output for under floor or weather compensated heating. This technology allows the boiler to provide two flow and return tapping pairs, for separate connection to heating and hot water circuits. FEATURES & BENEFITS Easy installation - wall mounted, ultra compact For weather compensation just add an optional sensor Automatic speed controlled pumps for increased efficiency Low cost 100mm diameter plastic flue saves on installation cost No need for mixing or controlling valves Dual flow technology enables the boiler to produce two different flow temperatures at the same time Wall mounted Integral pump exercise function Optional interface box can receive an external 0-10 volt signal to set boiler module temperature Automatic Lookout avoidance - the boiler can anticipate problems in advance Suitable for open vented or sealed systems Keston Brochure PDF

KESTON MULTI-BOILER PRE-FABRICATED RIGS

• Keston Rigs PDF

KESTON MULTI-BOILER PRE-FABRICATED RIGS The Keston concept has an established history of reliability, with thousands of boilers being successfully installed in commercial, industrial and domestic premises throughout North America and Europe. The modular design means almost any heating output can be achieved. The SEDBUK 'A' rating of our complete range ensures peak operating efficiencies and minimum running costs. Factories, commercial and public buildings, ranging from schools, blocks of flats, offices, hotels, pubs and restaurants through to sports halls, department stores, hospitals and museums, are just some of the applications that have benefited from installing Keston condensing boilers. The Keston Rigs are delivered to site pre-assembled and incorporate up to five units within a floor standing frame and up to 20 boilers operating in sequence across multiple frames. A dual boiler wall-hung rig is also available. The units are pre-piped to a single balance header. THE MODULAR APPROACH The compact size and versatility of the Keston makes it the perfect solution for a modular system, offering the designer complete freedom of choice. A boiler sequencer is included with integral weather compensating control to ensure optimum use of plant to meet demand and rotation of lead unit. The balance header includes tappings for air vent; fill point/expansion vessel, drain off and system flow and return. The number and size of system tappings is as per the customer's own specification. RIG OPTIONS In today's complex design approach it's common to have systems which require a number of different flow temperatures such as underfloor heating, weather compensation, DHW via indirect cylinder, air handling units, etc, the Keston plant rig approach can solve this problem by incorporating diverter valves to selected boiler(s). In this way the selected boilers can be seconded from serving the main system flow to serve another requirement at another flow temperature. Once this requirement is satisfied the selected boilers are diverted back to join the other boilers serving the system at the main flow temperature. Whilst the boilers are seconded away, the rig controller automatically increases the power demand from the remaining boilers to compensate. This can be repeated with other boilers at other temperatures to meet user requirements. Indeed, Keston can accommodate almost and rig requirement including integrated DHW storage, system pumps, pressurisation units and more.
