    Looking to source / get a rocommendation on a thermostatic / tempering valve for a DHW line coming off a solar buffer tanks. The tank has no storage as its a stainless coil going through it. Its a pressurised system coming off a tank (1300lt) which is pumped ( Grunfos MQ345) spilts into (1) 3/4" line to buffer tanks & (2) cold water to house.DHW temp off buffer tank varies between 50C and 75C depending on the season / sun. There is also a DHW return line

    Currently have a reliance heatguard TMV2 in place but the pressure drop across it is massive & Reliance say the unit is for point of use mixing rather than for a whole house. Sounds like wrong valve was put in day one

    Looking for advice / recommnedation ( PM if possible) for a tempering / thermostatic mixing valve for a large house with a low pressure drop across it capable of 60 lt/min . If it could accept a DHW recirc line that would be a bonus. Many thanks
