"A very basic product with just as basic fitting instructions. If this is a one off things you might like to buy at the same time are some ptf tape, a length of heat resistant cable, two flexible pipes with female connections at one end and appropriate connections for your installation at at the other. If your mains pressure exceeds 6 bar you will need to fit a pressure reduction valve. In areas of fluctuating high pressure it is best to fit one in any case. The unit is quite compact, enclosed in a plastic insulation filled shell and feels sturdy enough, when working the external surface is mostly cool indicating a good level of insulation. There is a little heat, nothing to cause concern, in the area of the control panel where there is not as much insulation. A bracket, without fixings, is provided for wall mounting or it can sit under a sink. A 6 bar pressure release valve is provided and you will need a T to include it if fitting new pipe work. Once you work out how to get the cable in through the conduit at the bottom rear and connected up the terminals by removing the front panel installation is easy. I think they could have pre-fitted an appropriate cable. The instruction manual is almost generic and of minimal help in illustrating the unit or panel removal. It has a plumbing diagram showing the correct location of the pressure release valve and minimum pipe requirements to allow for water expansion. It is a good enough unit but my feeling is that the manufacturer could have been a little more helpful in describing the unit in the installation instructions. It is very similar to larger units of this type found in other parts of Europe at lower cost. Maybe in the inflated UK market it is good value."
