Karcher K series question.

Is it safe to be able to connect a K series to a Hot water supply or will it damage the pump and motor.

Thanks and Happy Christmas to everyone.

Maybe.

I imagine it will overheat.

why would you want to do that?

Would be massively impressed if you got enough water pressure from a hot tap, but also confused why you would?

Hot water cleans better. Same as it does in your kitchen sink.

Check the spec of the model you have, some can take hot water, most can’t.

If you want a hot water pressure washer the best type are the ones which heat the water up for you.

Thanks everyone for your replies. It was just a thought when cleaning the car.
Probably best to just use it cold.

K series? Probably unlocked, try overclocking it.

Mate over the road has just done his -He has a hot and cold tap within a few feet of each other - he made up a Tee piece to join taps - all he does is turn on hot tap just a bit then turn on cold and mix them till he gets a constant warm flow -Not red hot but medium hot and it works a treat - It didn't leave any of that white road smear on doors or wings - he also used a traffic film remover before he started.
I was impressed but did wonder about heating oil bill.

PS he is on a combi boiler so pressures should be the same -also he was thinking a non return valve on each supply.

Also the HOT water would make most garden hoses go soft and they may just collapse with the suction

They don't use much water at all when running, you can run some from a barrel or other container of water. The biggest issue is the K series uses the water to cool the motor so "hot" water could damage the motor.

If you want hot water to help you clean your car, then I'd suggest you get some proper car cleaning products.
I don't know what you currently use, but you can buy a number of different products that make it easy for you to wash your car and don't need you to use the pressure washer to clean the car.
