Here’s one on the cost-benefit of installing thermostatic mixing valves: “It is very likely that installing TMVs as standard in social housing in new buildings and major refurbishments accompanied by educational information represents value for money.” Here’s a powerpoint from the American Burn Association discussing scald prevention: […]
