PulsaCoil A-Class
An open vented mains pressure hot water system
PulsaCoil A-Class With Front Exposed Tried and tested in the market place for over 20 years

PulsaCoil A-Class is the latest evolution of Gledhill ’s low tariff electrically heated mains pressure hot water system which delivers the same exceptional hot water performance as ever but is now even more efficient,more responsive, simpler to install and operate.

Requires no pressure relief, no
tundish – no runaway of any kind.

PulsaCoil ’s ability to provide mains pressure hot water at high flow rates without the need for pressure or temperature relief valves, tundishes and associated run- away pipework has made it the no.1 choice in new build apartments and inner-city conversions.

Immersion heaters that can never scale

Because the immersion elements are situated in the same primary water all the time and this water is not renewed, no scaling takes place, even in hard water areas.

No annual service required

The appliance ’s advanced construction ensures a long life and the primary store design removes the need for annual checks on sacrificial anodes, found on many unvented units.

Smaller Size
With the width reduced to just 530mm and a height reduction of up to 260mm on the largest models, PulsaCoil A-Class will fit in a smaller space and there is now even more usable space in the airing cupboard. All this is achieved despite an improved performance from each unit.

Easy to Install
All models are supplied shrink wrapped with built in moulded lifting handles.All controls and pipe-work are mounted on the front face of the unit for ease of installation and maintenance.

Gledhill ’s revolutionary design enables rapid second fixing using copper or approved plastic piping and a variety of optional fixings, such as flexible pipes and push fit connections.

Water Treatment
The Domestic Heating Compliance Guide published in May 2006 requires a water treatment device to be fitted where the hardness is greater than 200ppm. This is a requirement for both combis and storage vessels to comply with Building Regulations L1A and L1B. The Gledhill in-line scale inhibitor CAN BE SPECIFIED AT TIME OF ORDER for a very modest cost. This is fitted within the case and therefore does not require the provision of a fused spur in the cupboard.

Significant Reduction in Site Wiring
Fused power supply circuits have been reduced from 3 to 2 and this means a significant saving in site wiring.

Simplified Electrical Connections
Incorporating Pushfit electrical wiring terminals means faster installation and more reliable connections.


Integral Boost Facility
PulsaCoil A-Class comes complete with a boost button on the front of the appliance. This eliminates the need for a separate boost timer and associated wiring – saving time and money on site.
