FAQs about Alpha Boilers

Here are a few common questions regarding Alpha system boilers. If you have any more concerns, don’t hesitate to reach out to our team.

No, Alpha system boilers do not require heat pumps. They work as standalone systems alongside hot water cylinders and radiators. Heat pumps are optional and only used in hybrid or more modern low-carbon setups, so they are not needed for the boiler to function normally.

This will depend on the model you choose and your home’s pre-installation requirements. Boilerhut offers a free and simple quote process that can be done fully online. Get an online quote now by simply sending us some pictures and your home requirements.

Yes, smart thermostats can be used with Alpha system boilers. The E-Tec NXS is compatible with OpenTherm and Alpha BUS control, while the ProTec NX only supports OpenTherm. Our Alpha system boiler installers will advise you on which is best for your home:

  • OpenTherm: Allows a smart thermostat to modulate the boiler’s heat output in real time for better efficiency and comfort.
  • Alpha BUS: Alpha’s own communication system that links heating components for more precise and coordinated control.
