The most reliable and efficient boiler money can buy
Designed with reliability, performance, outstanding efficiency and long term value for money as key considerations the QuanTec range also include isothermic and full heat condense stainless steel heat exchangers with ‘cool door’ technology, low carbon and low NOx levels and pluming reduced to almost invisible levels. Combined with ease of installation and maintenance it makes the QuanTec boilers the homeowners’ and installers’ choice.
Included in the range is Johnson & Starley’s flagship model the HR28C with integral Passive Flue Gas Heat Recovery. Currently no other manufacturer can compete with the HR28C in size and performance, making it possibly the most efficient boiler in the world!
Johnson & Starley’s QuanTec HR28C is the latest innovation for combi boilers. Exceptional efficiency in gas consumption is achieved by the Full Heat Condense heat exchanger which incorporates a Domestic Hot Water (DHW) pre-heating function. This is achieved by extending the path of the flue way to pre-heat the water circulating in the additional coil on the back of the heat exchanger, utilising all the energy from the flue gases.
This enables the HR28C to reach an efficiency level never reached before (110% in DHW mode) and substantial energy savings (<25% in gas consumption). Savings of up to 26% in hot water demand, in addition the HR28C considerably reduces CO emissions and is 100% recyclable so it’s working hard to protect the environment even further. All this whilst, with dimensions of 780x423x321, it still retains the same size as a standard boiler.
