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 you will always have heat and hot water where and when you 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 you already have 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: you can cut your gas consumption by up to 82.5% when Xtend split is paired with any of our Intergas ErP combi boilers. You will still enjoy substantial gas savings should you choose to have Xtend split retrofitted to your existing ErP boiler or paired 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 monobloc (the outdoor and the indoor units) to an existing Intergas ErP combi or system boiler, that boiler warranty is increased too.

Don’t need the full package?

You don’t have to buy a combi or system boiler or accessories from us to unlock the benefits of our hybrid heating system, you can simply buy our indoor and outdoor units (they come as a pair) and have them retrofitted to your existing boiler, providing it’s compliant of course. These two units come with a five-year parts and labour warranty.

Ultimate efficiency

When you have an Intergas combi boiler installed 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.

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).
