How much does it cost ?
The thermostatic mixer is a bit more expensive than a traditional faucet, but you will quickly realize that you have made the right choice. Firstly the price difference is only a small amount. Secondly, the thermostatic mixing valve will allow you to consume a lot less water, and thus considerably reduce your water and energy bills.
There are efficient mixers at all prices, however, we advise you to avoid entry level products which may need to be replaced frequently or could even burn you. Also, purcahse products that have been approved to a thermosatic standard. Ask your installer or supplier to confirm.
