Hi all
I've got a couple of old solar panels I recued from going to the dump and a water tank from a boat, which has a heat exchanger coil and an immersion heater in it. I plan to rig this up for the small hotel I run. I can't break into the main hotel system at the moment but can get the tank output from the tank to the laundry, to run that on solar hot water, which is a start! My question for all your learned minds is this. I'm used to washing machines in the UK with hot and cold water feeds but where I am in Portugal, the machines only have one feed, from the cold. So I thought just stick the solar hot water in the machine and the built in thermostat will just turn the heating element on for a shorter time, as feed water will be preheated. But then I realised if I get hot, hot water this might be too hot for particular clothes being washed. So my solution is to put a mixer that came with the tank on the "T" from the cold pipe and solar hot water pipe. Then when washing, just set machine wash temp on the mixer adjuster as well as the machine controller dial itself. Any comments on this? Seems so simple there must be something wrong. Appreciate any thoughts.
Thanks
