Xtend split hybrid

Xtend is our hybrid heating system that will revolutionise home heating. Not only is it a serious energy saver, cutting gas consumption by up to 82.5%, Xtend provides all the comfort of a traditional heating system, so the homeowner will always have heat and hot water where and when they want it.

We call Xtend a ‘hybrid’ because it combines two technologies: a gas combi boiler and a heat pump which comprises a 5kW split air source heat pump (ASHP) and a compact indoor unit. The indoor unit acts as a distribution centre, connecting and controlling both the outdoor unit and the boiler during a heat demand.

The combi boiler provides the hot water and the heat pump heats the home via radiators or underfloor heating. When the temperatures drop, our smart system will alternate between the boiler and the heat pump, ensuring comfort levels are maintained and the most energy-efficient combination of appliances used. The fan in the ASHP modulates its speed to meet the heat demand, which keeps energy consumption as low as possible and, as it generates energy from the outside air, it has zero emissions, making Xtend an excellent low carbon heating system for today.

If the homeowner already has a compliant Intergas ErP combi boiler installed, then Xtend – the indoor unit and outdoor unit (ASHP) – can be retrofitted to it, substantially reducing the installation time, not to mention the cost.

Please note: your customers can cut their gas consumption by up to 82.5% when Xtend split is paired with any of our Intergas ErP combi boilers. They will still enjoy substantial gas savings should they choose to retrofit Xtend split to their existing ErP boiler or pair it with another manufacturer’s ErP system or combi boiler.

15-year boiler warranties. Yes, really!

Xtend comes packed with so many features and benefits, it’s easily one of the best hybrid heating systems in its class. Take the boiler warranty, whatever Intergas boiler the homeowner chooses as part of Xtend, we’ll increase its warranty. For example, the Xtreme, Xclusive, Eco RF and HRE warranties are all extended to 15 years and the Rapid and Rapid Plus to 10. If you retrofit Xtend monoblock (the outdoor and the indoor units) to an existing Intergas ErP combi or system boiler, that boiler warranty is increased too.

Design freedom

Another benefit of Xtend is that we’ve kept it compact to give you and the homeowner control over where the indoor and outdoor units are installed. Our indoor unit is one of the smallest on the market and can be fitted anywhere in the home providing it’s within 15m of the boiler. Similarly, the outdoor unit (ASHP), which is smaller than a stand-alone heat pump, can be sited outside the property, as long as it’s within a minimum distance of 3m or a maximum distance of 25m from the indoor unit.
Please note: the installation must comply with manufacturer’s instructions and building regulations.

Ultimate efficiency

When you install an Intergas combi as part of our hybrid heating system, you’re guaranteed efficiencies others cannot match. Thanks to our revolutionary bithermic heat exchanger, all our boilers condense in both heating and hot water modes, respond to the demand for heat faster and keep carbon emissions as low as possible. Add to this a robust build, a maximum of four moving parts and no diverter valves in our combis, you have boiler reliability that’s off the scale.

Sound advice

If it’s a pump, there will be some noise, but with our outdoor unit (ASHP) you can relax in the knowledge that at only 34dB(A) at five metres, it’s exceptionally quiet. For context, a soft whisper is 30dB(A).

Xtend provides all the comfort of a traditional heating system, while cutting gas consumption by up to 82.5%. 

Hybrid heating systems are suitable for a diverse range of properties and deliver immediate carbon savings.

Seasonal Coefficient of Performance (SCOP)

For an air to water heat pump to work, the outdoor unit must be supplied with energy in the form of an electrical current. This is combined with energy supplied from the outside air and thermal energy is then produced to provide central heating. The key indicator of a heat pump’s efficiency is its SCOP value. The value shows how much thermal energy (in kW) the heat pump produces for every kW of electrical current supplied, averaged out across one year (all four seasons).
