You get a wall plate included,time clock extra,if you are doing straight swop,note the flue is off centre
There are doing a cheaper eco combi range,this has no wall plate and you have to purchase fittings to flow and return and cold water isolation ,also just standard flue and elbow supplied,no other flue arrangement recommended on this model
I use HPS in london,if you ring Rehema they will give you any local stockest
If fitting for first time,read up on start up sequence when first power up
