Alpha Evoke NX 28kW boiler installation in Tonteg
For this home near Pontypridd, SwiftHeat UK Group Ltd fitted an Alpha Evoke NX 28kW combi boiler to provide central heating and hot water on demand. The boiler is A-rated for heating, with an ErP seasonal space-heating efficiency of 94%.
Kieran Heycock, our Principal Engineer, was the homeowner’s point of contact. He fitted a Hive Mini wireless thermostat and set the heating schedule around the household’s routine.

What we fitted and how we handed it over
Flue and system protection
We fitted an Alpha vertical flue and a magnetic filter. The filter captures magnetic debris circulating in the heating water, helping to protect the new boiler.
Hive Mini heating controls
The programmable wireless thermostat was included at no extra charge. At handover, Kieran showed the homeowner how to operate the boiler and adjust the schedule on their new controls.
Commissioning and notification
We carried out the installation checks, commissioned the boiler, completed the Benchmark checklist and notified the installation through Gas Safe for the Building Regulations compliance certificate.
Every SwiftHeat boiler installation also includes a complimentary Boiler Management Condition Report.
Warranty cover and support after handover
We registered the boiler with Alpha for its seven-year parts and labour warranty, subject to Alpha’s terms and annual servicing. SwiftHeat provided a separate 12-month installation workmanship guarantee.
When the boiler pressure later dropped, the homeowner contacted us. We helped restore the pressure, reset the boiler and checked that the heating was working again.
