We installed one of their heaters in a Church vestry which was ok for about 8 weeks then problems started.
They wouldn't reply so we paid for outsourced parts but their product just isn't reliable. Ended up installing a different heater and being approx £600 out of pocket.
Still no response to our 2 tickets raised, just a bot acknowledging receipt.
