You have spliced into a heater hose to warm your washer fluid? I really hope you haven't. Allowing coolant and washer fluid to mix is going to be detrimental to both systems never mind the opportunity for leakage and catastrophic failure of the cooling system.

I made a washer fluid heater that is spliced into the heater hose. Works well.

Also thermal shock is not good for a windscreen. Unless you like keeping Autoglass in business.

The system is as follows.
A short length of 15mm domestic copper pipe surrounded by a piece of larger bore copper pipe. The ends of the larger bore sealed to the 15mm to produce a container. Water from the washer hose enters the tank via small bore copper brake pipe and exits via another brake pipe. Both ends of the 15mm pipe have copper/brass olives to prevent heater hose from sliding off. One brake pipe needs to be full length to enable washer fluid to get hot.
Points to note.
The coolant and washer fluid do not mix. This is purely heat transfer from one fluid to another via a copper pipe.
Adding the olives to the ends of the 15mm pipe prevents the hose being pulled of the pipe. They are in effect acting in the same manner as the ridges formed in normal heater pipe.
The system was installed approx. 30 months ago. It doesn't leak and hasn't failed.
I tested the temperature of the water at the washer jets and found that the drop between the device and the jets was enough to quell any thoughts of cracking the glass.
If anyone would like detailed measurements of the device, just ask.

That sounds fresh out of practical classics 1950s edition, certainly not something I would be doing to a car new enough to still be under warranty. Very hard pass from me I'm sure.

Roger, very ingenious rig, thanks for posting! Very clever.
I've considered installing a short length of foil hose under the hood to duct some of the engine's waste heat up to the region of the windscreen washer bottle, but your solution is definitely much more sophisticated.
A photo would be great, if you can get a good angle for a pic.

Why not just fit a 12v 50w fish tank heater into the washer reservoir with a thermostat to keep it at a gentle 10 degrees. Save the modification of the cooling system, then if it does fail the somewhat critical engine cooling system is unaffected?
