The Sanden Quick Connection Kit includes the tempering valve, ECV (Expansion Cold Water Valve), elbows, insulation gloves for all the elbows and valves so you have the most efficient set up - you can't buy the insulation gloves separately. Makes the plumbing install much quicker (plumber only needs to source copper + lagging for the copper). Always highly recommended to ensure the Sanden is installed to specifications
Normally a house with upto 2 bedrooms is 15mm and 3+ is 20mm.
