Alpha Evoke NX Combi Boiler 28–33kW
The Alpha Evoke NX is Alpha's merchant-range natural gas combi with a renewed stainless steel heat exchanger, a straightforward replacement combi for flats and small to medium homes. Choose 28kW or 33kW. It uses the same Alpha CD 60/100 flues and accessories as the E-Tec NX.
Key points
- 28kW and 33kW models (28NX and 33NX), natural gas
- Stainless steel heat exchanger in a lightweight thermoplastic moulding
- Grundfos hydroblock with Delta T variable speed pump
- Adjustable heating flow temperature and range-rated output
- Combined expansion relief and condensate drain
- Weather compensation ready; OpenTherm and Alpha BUS controls
- Removable push-fit 60/100 flue connection
Required with this boiler: a flue kit
Alpha supplies this boiler without a flue (only the flue turret is in the box). The Flue kit selector above Add to cart adds the Alpha CD EasyFlue 1000mm telescopic horizontal flue kit (6.2001010) by default, as a separate line in your basket. Pick the Alpha CD vertical flue terminal with 1m flue (6.2000520) instead for a roof exit.
Only choose "I already have this" if you already have a compatible Alpha CD 60/100 flue kit for this boiler. Check maximum flue lengths and terminal positions in the installation manual.
What's included
- 1 x Alpha Evoke NX boiler in the output you select, boiler only, as supplied by Alpha
- Flue turret with seals, connection kit with valves, wall mounting bracket, condensate pipe and literature pack, as supplied by Alpha
- Free with this deal: one Alpha flue and one flue bend from our stock (see above)

Dimensions (H x W x D): 712 x 440 x 253mm (Alpha installation instructions). Maximum flue length 12m horizontal, 14m vertical including the terminal.
