I’ve read threads that suggested using a water heater that was designed for camping. I thought about trying it. I happened upon an inline heater designed for portable carpet cleaning machines, The Mytee 240-120. I’ll try to put a link to the Mytee webpage below. The heater doesn’t produce any pressure. The water is heated as it flows through. There is 4 settings depending on how cold the input water is and how hot you want it to be in the end. Have you heard of anyone using a machine like this? It seems like it would work.
Seems like the heat of the water could be to high for window cleaning. In colder temps the water from a standard hot water system (or even one of those camping water heaters) isn’t a lot higher than 80-90 degrees Fahrenheit at the jets. The temp from the carpet cleaners heater could shatter the glass.
Tony-
The MAX temp on this unit lists 210 degrees @ 2400 watts, but they have lower settings. 600, 1200, 1800, & 2400 watts
So if the math worked out to be simple enough at 600 watts you could expect the water temp to be 50 - 60 degrees???
Just thought I would mention it is variable power/heat.
That’s a good point but still you could only use one or maybe two settings (unless you clean carpets) and it costs almost $500. The campsite heaters cost under $200 and would be more useful for wcers. jmo
In that instance, you would be correct. I am not familiar with the campsite heaters.
This is the one I’ve seen reference to. I may buy one myself. You’d have to buy fittings to attach it to your wfp.
Eccotemp L5 Portable Tankless Water Heater - Lowest Prices GUARANTEED!!
It seems like I read thread a while back and the idea that I understood was that the L5 may not last very long with continuous use. The thing about the Mytee heater is that it is designed for continuous commercial use. The guy at the carpet cleaning company told me that it would raise the water temp about 60-70 degrees. He told me that it would get the water up to 210F if you used it with a portable exreactor filled with warm to hot tap water. At any rate, I’ll probably be getting one for my portable exreactor anyhow. I thought I would pass the idea along. I’ll post the results of using it for WFP later for the curious and/or interested.
You also need to find out the minimum flow rate of the water. Most in the UK have been limited by the actual unit requiring a steady high flow to make the unit function meaning a lot of waste water which is not an option in the UK. This can be bypassed by altering the unit/having a break tank.
Thats a great point that I hadn’t considered! I’ll have to consult the Mytee people. Thanks:D
I wanted to kickstart this thread. Seems like there is more interest in heated pure water these days.
Seems like the Mytee 240-120 would be a perfect inline heater for wfp purposes. Does anyone run something like this:
I was thinking about making a box and line it with black paint and putting a glass top on it. Kinda like the solar water heaters you see on peoples roofs just diy. I guess they can get to 150 degrees in the summer.
looks cool, but pricey. also, i didn’t see any volume output stats in that link. that would be good info.
essentially, you trade the propane tank from the L5 or L10 for a buttload of extension cord.
You could run a short one through the customer’s window into an outlet. I do that all the time to run my air compressor at home - no outdoor socket. I’ve noticed that there is usually a window nearby any hose bib esp. on the front of the house.
I use a 1000 watt submersion heater in my 25 gallon tank during th colder months. Fill the tank the night before, turn on the heater right before bed, and the tank is piping hot by morning, and appears to keep the rest of the car defrosted, as well. Water stays plenty warm for several hours. I don’t have room for an on-board heater.
One tip if you’re going to go this route: wrap the opening on the top of the tank with plastic to cut down on evaporation- otherwise you’ll have a quart of moisture inside your vehicle! You could also modify a second lid for just the heater.
Seems a lot less hassle using a propane tankless… Not to mention you can get one for around $120 and no need to find an outlet.

Thanks for the feedback [MENTION=2739]advantage202[/MENTION] and @Pure Water Window Cleaning. Great video Joshua.
Do you use hot water during all seasons or just the cold months?
[MENTION]@CapeCodCleaner
I love it for late fall, winter and early spring. I don’t use during the heat of summer since we are normally 90-100+ thru summer. But some people like to use it year round.
Thanks! Similar to Jeremiah, we mostly use it when the temperature is close to or below freezing.
However, we also use it for first cleans. It really cuts down scrubbing power. I’d say it cuts the work in half. Bird dirt comes off sometimes without even scrubbing and I’ve even avoided laddering up on several construction cleans with tape and silicon which I just scrubbed super hard with hot hot water.
I had a cool experience last year. I was heavily marketing to a condo development when I got a call from the pm. She said that she’d love to utilize our system and techniques because there was no other company in the area who could reach certain difficult access buildings. However, because she didn’t trust our technology, she would like to see the results up close and personal on a small job before she’d let us submit proposals for a dozen of her properties. The building where she lived had hard access windows that hadn’t been cleaned since 1989, when the structure was built. 4 panes, $80, 15 minutes with hot water. It led to winning 10 of the 12 properties she presented our proposals for.
