I have a house with underfloor heating fired by a Baxi Luna

Customer Question

I have a house with underfloor heating fired by a Baxi Luna 3 comfort ht 330 boiler.
For the third time over several months, the boiler does fire up when the heating is turned on at the controls inside the house.
the controls have been switched to 'off' over summer but now the colder weather is near, we want the house heated.
We were never given a manual with instructions when the unit was installed 18 months ago and would like to obtain a new hard copy.
The person who installed it does not seem to be much help - just says 'it should go on when you turn it on in the house'!!
