Intergas Xtend – the hybrid
The hybrid heating system that will revolutionise home heating. Not only is it a serious energy saver, cutting gas consumption by up to 82.5%, but Xtend provides all the comfort of a traditional heating system, so you will always have heat and hot water where and when you want it.
It combines two technologies: a gas combi boiler and a heat pump comprising a 5kW split air source heat pump (ASHP), the outdoor unit, and an indoor unit.
The combi provides the hot water, and the heat pump heats the home via radiators or underfloor heating; when the temperatures drops, the combi assists the heat pump in heating the home.
As the heat pump generates energy from the outside air, it has zero emissions, making Xtend an excellent low-carbon heating system today.
The only problem is that it is not eligible for the boiler upgrade scheme grant.
If this changes a lot more people will be willing to embrace heat pump technology and that will make a real difference to CO2 emissions.

WHAT IS ‘TEMPERATURE DIFFERENTIAL’ IN HEAT PUMPS?
“Temperature differential,” often referred to as Delta T (Δ ΔT), DT, or flow/return, is a term used in various engineering and scientific contexts to describe the difference in temperature between two points. In the context of heating, ventilation, and air conditioning (HVAC) systems, as well as in hydraulic and thermal engineering, it has specific applications:
HVAC Systems: In HVAC, Delta T is the difference between the air temperature entering a system (inlet temperature) and the air temperature exiting the system (outlet temperature). This difference is crucial for assessing the efficiency of the heating or cooling process. A higher Delta T indicates a more efficient transfer of heat.
Hydraulic Systems: In hydraulic systems, especially those involving heating or cooling, Delta T refers to the difference in temperature between the fluid (such as water or hydraulic fluid) as it enters a component (the flow temperature) and the temperature as it exits (the return temperature). This concept is essential for evaluating the performance of radiators, heat exchangers, and similar components. A properly functioning system should have a specific Delta T, indicating effective heat transfer.
Thermal Engineering: In broader thermal engineering applications, Delta T is used to calculate the heat transfer in processes, design systems, and ensure that devices operate within their intended temperature ranges. It’s a fundamental parameter in the equations of conduction, convection, and radiation heat transfer.
Understanding Delta T is essential for optimizing the performance of systems and ensuring they operate efficiently and effectively. It helps diagnose issues, improve energy efficiency, and ensure the comfort and safety of environments and processes.
