Hot water enhancements are able to provide far greater control over how water is delivered, to where, and in what quantity. Likewise, when they're installed and used appropriately, they can also help you cut down on the amount of water wasted in your home.
Temperature controllers
These devices allow you to automatically set the exact temperature of water from a given tap, and in some cases even to specify to what level a bath or sink should be filled.
Hot water recirculation systems
Also known as 'comfort pumps', these systems pump hot water through your pipes to ensure that it's always available when and where you need it.
Cold water diverters
In most plumbing setups, it takes a while for hot water to reach the hot tap when it's turned on. Cold water diverters recycle the cold water which would otherwise pour down the drain in this time.
