BOXT customer reviews of the Vaillant ecoTEC plus

We have recently had a new boiler installed [Vaillant ecoTEC]. The team that have sold, supported, installed and after care has been exceptional. I would absolutely recommend this company in a heart beat.

Steven Coppinger

so happy with my new boiler [Vaillant ecoTEC plus]. It’s sitting pretty on my kitchen wall and I couldn’t be happier. Overall, thanks to BOXT for an outstanding service.

The process was easy we opted for a Vaillant ecoTEC plus 836 combi boiler which would replace a traditional water tank fed system ...5 well deserved stars all round 👍
